Fischer Connectors launched an even smaller ultra-miniature connector, MiniMax 06, as an extension of its miniature high-density product range, the Fischer MiniMax Series. The MiniMax 06 connector can include up to 12 power and signal contacts in a footprint of only 10 mm. This corresponds to a density factor of 0.83 – a unique technological feature for a connector with standard 0.5 mm contacts. The new MiniMax 06 connector also includes a new unique configuration with 2 signal and 2 high-power 1.3 mm contacts for applications needing 10 Amps or more power, doubling the standard 5 Amps current rating of the existing MiniMax product line. MiniMax 06 is easy to use and ensures premium performance even in harsh environments. Also available as a pre-cabled solution, it is ideally suited for handheld or body-worn applications when space is limited, in such fields as defense and security, instrumentation, testing equipment, civil or military unmanned aerial vehicles (UAVs), among many others.
Increased power & miniaturization with continued durability With this new smaller connector, Fischer Connectors continues to drive the evolution towards combined signal and power connectors as a way of making electronics lighter and smaller. MiniMax 06 integrates fully into the ultra-miniature high-performance Fischer MiniMax Series, well-known for its use in limited space and lightweight applications, and for meeting the combined needs of multiple signals and power. Tested for high-speed protocols such as HDMI and data transfer up to 10Gb/s, the series also addresses the growing market need for higher data transmission rates.
To meet the growing demand for precise and reliable compensation resistors used in building transducers such as load cells, Micro-Measurements announced that its bondable resistors for transducers are now being built on Advanced Sensors Technology and feature high-purity nickel. The LT02 and LT10 series of fixed-value nickel resistors offer tight resistance tolerance and repeatable performance for use in transducer bridge completion circuits.
As the foundation of consistently reliable and precise transducers, Micro-Measurements' Advanced Sensors bondable nickel resistors are built on a new manufacturing process using state-of-the-art equipment and tooling. This results in a tighter tolerance, better stability, and shorter lead times when compared to conventional manufacturing techniques. Customers who have tested the resistors in transducer products have reported more repeatable test data when compared with previous-generation conventional resistor types.
For the highest accuracy, precision strain-gage-based transducers require compensation for several undesirable influences, most notably the influence of temperature change. These compensations are typically effected using precision resistors of various values and temperature sensitivities. Micro-Measurements offers a complete line of bondable precision resistors for use as transducer compensation elements, including fixed-value and adjustable resistors manufactured using either high- or low-TCR materials.
Micro-Measurements fixed-value resistors, such as the LT02 and LT10 patterns, are typically used for adjusting the full-scale span output with temperature changes, and they are therefore normally produced in high-TCR resistive alloys such as Balco or nickel.
IXYS Corporation announced the introduction of the PCX-7500-LIV and PCX-7500-LIV-EX high-power laser diode driver/current sources by its IXYS Colorado division. These instruments provide precision pulsed current with accurate microprocessor-based digital power control.
The PCX-7500-LIV is an air-cooled, benchtop current source designed to drive laser diodes, bars and arrays at up to 60 amperes of current, 110 volts maximum forward voltage and 1 kilowatt maximum output power. Pulse widths are adjustable from less than 20 microseconds at 10 amps to less than 200 microseconds at 1 amp. The PCX-7500-LIV is ideal for research, laboratory, scientific and industrial applications.
The PCX-7500-LIV model is a stand-alone instrument that includes an internal diode compliance voltage power supply. The PCX-7500-LIV-EX model is comparable in current pulse specifications to the PCX-7500-LIV, but requires an input DC power supply up to 125 volts to provide the diode compliance voltage. The flexibility of this configuration allows the user to drive laser diodes over a broad range of compliance voltages with a single PCX-7500-LIV unit, from single diodes to large multi-diode arrays.
Utilizing one of several communication choices that are standard with the PCX-7500-LIV, users can easily develop automated testing and characterization configurations that can be stored in the instrument's on-board memory. It may also be operated through its intuitive front panel controls. Its color QVGA LCD display provides immediate visual confirmation of all operating parameters.

Wolfspeed has introduced the first fully-qualified commercial power module from its Fayetteville, Arkansas location. The high-performance 62mm module represents a new generation of all-SiC power modules that enable unprecedented efficiency and power density for high current power electronics, such as: converters/inverters, motor drives, industrial electronics, and high performance electric vehicle systems. The new module allows systems designers to realize lighter weight systems that are up to 67% smaller by achieving efficiencies of over 98% and improvements in power density of up to 10 times compared to systems built with silicon-based technologies.
Compared to conventional silicon IGBT power modules, or even previous generations of SiC MOSFET modules, the new module will offer significantly higher power density for applications in which volume and weight are critical limitations. Operating at a higher switching frequency without any compromise in system efficiency means a reduction in the number and size of magnetic and passive components required for the balance of the system. The superior thermal characteristics of SiC devices, along with the packaging design and materials, enable the module to operate at 175°C, which is a key advantage for many industrial, aerospace, and automotive applications.
The newly commercialized Wolfspeed module design is the industry's most optimized to achieve the unique benefits of SiC technology with a 66% reduction in module inductance to 5.5nH, compared to competitive power products at 15nH. This reduction in module inductance enables faster switching speeds, higher frequency operation, and ultra-low losses.
STMicroelectronics has introduced the new TSX7 series of precision 16V op mps that combine very high accuracy with a wide operating-voltage range and excellent robustness. The low input-offset voltage, Common Mode Rejection Ratio (CMRR), and temperature drift eliminate any need for trimming or calibration in the assembled circuit while ensuring consistent performance over a wide automotive-grade temperature range from -40°C to 125°C.
The new devices build on ST's advanced 18V analog manufacturing technology and the success of its TSX5, TSX6, and TSX9 series of low-power op amps.
The low input-bias current and the energy-efficient combination of low power consumption and gain bandwidth make the TSX7 series ideal for use in power-constrained sensor-signal-conditioning applications, while the wide supply-voltage range, stability in challenging operating conditions, and tolerance of electrostatic discharge (ESD) up to 4kV (Human Body Model) fit well in applications such as industrial equipment, building automation, medical instrumentation, LED lighting, and automotive Electronic Control Units (ECUs). In addition, the rail-to-rail input and output functionality allow the TSX7 op amps to be used for low-side and high-side current measurements without limitation.
Key technical features include:
The TSX7 op amps are in volume production, with prices starting from $0.52 for 1,000 units.
