Power supply ICs come in rad-hard plastic packages
Texas Instruments announced an expansion in its portfolio of space-grade analog semiconductor products in highly reliable plastic packages for a diverse range of missions. TI developed a new device screening specification called space high-grade in plastic (SHP) for radiation-hardened products and introduced new analog-to-digital converters (ADCs) that meet the SHP qualification. TI also introduced new […]
SMD TVS diodes feature higher surge handling for aerospace, avionics apps
Littelfuse, Inc. announced the new 5.0SMDJxxS-HRA TVS Diode Series. The high-reliability TVS diodes are designed, manufactured, and screened to provide robust overvoltage protection, with low early failures and zero degradation over continuous surge events. Today’s aircraft use more and new composite materials, thus requiring higher-level lightning protection for all electrical and electronic equipment. The 5.0SMDJxxS-HRA is […]
Multilayer varistors withstand severe flexing, vibration, and temperature cycling
KYOCERA AVX has released the industry’s first automotive-qualified multilayer varistors (MLVs) equipped with the company’s patented FLEXITERM soft termination technology, which has been widely employed on a number of automotive-qualified multilayer ceramic capacitors (MLCCs) for more than 15 years. Designed to satisfy automotive industry demands for more robust component solutions, the new VCAS Series MLVs with FLEXITERM […]
Current-sense shunt resistor offers 0.5 milliohm resistance, 3-W power rating
High-efficiency current sensing requires low resistance values. However, lead resistance may cause inaccuracies in sensing measurement for ultra-low resistance values. Four terminal Kelvin connections with separate sense and current flow connections eliminate the detrimental effects of lead resistance yielding a very accurate measurement of the power delivered. Stackpole’s CSSK3637 is a four-terminal device offering resistance […]
High-voltage contactors feature light weight, compact size
TE Connectivity released an additional configuration of its KILOVAC CAP120R contactor. TE’s KILOVAC CAP120R contactor is ideal for defense, marine, UAM (urban air mobility), UAV (unmanned aerial vehicle) commercial, and military aerospace applications requiring lightweight latching coils and reduced power consumption. The CAP120R contactor now features a high-voltage latching configuration. The 150-amp DC contactor also includes a […]
