A protection relay is a smart device that receives inputs like current, voltage, resistance, temperature, or even light, compares them to set points, and provides outputs such as visual feedback in the form of indicator lights and/or an alphanumeric display, communications, control warnings, alarms, and turning the power off and on. They are used for […]

Ferrites feature NiZn core, handle 1 MHz to 1 GHz EMI
Würth Elektronik is launching another line of retrofittable interference suppression solutions with AEC-Q200 qualification, as required for the automotive industry. The WE-CAR-TEC series snap ferrites feature a NiZn core material. WE-CAR-TEC ferrites suppress electromagnetic interference in the frequency range from 1 MHz to 1 GHz. The internal security locking system prevents unauthorized removal from the cable. […]
APEC 2023 announces first-ever student job fair
The Applied Power Electronics Conference (APEC) will conduct its first-ever Student Job Fair on Tuesday, March 21, 2023, from 2:00 p.m. to 4:00 p.m. at the Orange County Convention Center in Orlando.

Thermal gap filler incorporates carbon fibers to boost conductivity, maintain flexibility
Sarcon CF210A is the newest Fujipoly thermal gap filler and incorporates carbon fibers along with traditional fillers found in thermal gap filler materials. The carbon fibers allow for higher thermal conductivity (21 W/m•K) while remaining compliant. Sarcon CF210A’s compliance is closer to a much lower conductivity gap filler such as Sarcon PG25A. While the thermal […]
650 V GaN HEMTs now offered with 80mΩ RDS(on)
Innoscience Technology announced a new low RDS(on) 650V E-mode GaN HEMT devices. INN650D080BS power transistors have an on-resistance of 80mΩ (60mΩ typical) in a standard 8×8 DFN package, enabling higher power applications, for example in totem pole LLC architectures or fast battery chargers. Thanks to Innoscience’s innovative strain enhancement layer, InnoGaN devices feature low specific RDS(ON) as […]
Co-polymer resin meets strict requirements for 1.6Kv solar systems
SABIC launched a breakthrough polycarbonate (PC)-based copolymer resin, well-suited for photovoltaic (PV) connector bodies, that meets stricter performance and regulatory requirements for emerging 1.5Kv solar systems. The new LNP EXL9334P copolymer resin achieves the highest comparative tracking index (CTI) level (UL PLC0) and IEC as Material Group 1 (IEC MG 1). It also delivers low-temperature […]
eGaN power FETs feature high power density, tiny footprint
EPC launches the 80 V, 4 mOhm EPC2619. This is the lead product for a new generation of eGaN devices that have double the power density compared to EPC’s prior-generation products. The EPC2619 has an RDS(on) of just 4 mOhms in a tiny, 1.5 mm x 2.5 mm, footprint. The maximum RDS(on) x Area of […]
Power management IC optimized for OLED screens
Magnachip Semiconductor Corporation announced that the company has launched its first Power Management Integrated Circuit (PMIC) for IT devices equipped with OLED screens. A PMIC is a core component to supply power to electronic devices. It plays an increasingly important role as the battery life of handheld IT devices like laptops and tablets is highly […]
Gas-discharge tube surge arrestors feature low capacitance, insertion loss
Bourns, Inc. expanded its next-generation Gas Discharge Tube (GDT) line with a 3-electrode surface mount product family. With the introduction of its Model GDT35 Series, Bourns continues to set the standard for breakthrough overvoltage surge arrestor performance by significantly heightening the level of protection against voltage transients caused by lightning or accidental contact with AC power lines, offering […]
