Littelfuse has introduced a new series of SIDACtor Protection Thyristors in DO-214AB (surface-mount) packages, designed to protect low-data-rate interfaces and outdoor data interfaces in general industrial applications. The Pxxx0S3NLRP Series provides robust surge protection performance at up to 2.5kA, while maintaining much lower switching threshold (VS) and on-state voltage (VT) than traditional protection solutions like […]

Flyback transformers sport low leakage inductance
In partnership with Dialog Semiconductor, Wurth Electronics Midcom announces the new flyback transformers for iW1818 and iW1830, reference designs for AC/DC controllers. Equipped with single or dual outputs, these MID-OLDIAOLDIA offline transformers offer high efficiency, low leakage inductance, and excellent EMI performance. The new, reinforced, insulation, flyback transformers are best suited for white goods, home […]
How to select input capacitors for a buck converter
by Maniing Xie, System Application Engineer, Power Design Systems, Texas Instruments Electromagnetic interference (EMI) can create serious issues for manufacturers in an industrial environment. A buck converter generates a pulsating ripple current with high di/dt at the input. Without input capacitors, ripple current is supplied by the upper power source. Printed circuit board (PCB) resistance […]
Low resistance resistor jumper operates at -55°C to +170°C
KOA Speer Electronics introduces the TLRZ series metal plate zero ohm jumper, available in 0603, 0805, and 1206 package sizes with current ratings of 26A, 31.6A, and 40A respectively. The TLRZ is a low resistance resistor jumper with an operating temperature of -55°C to +170°C. The TLRZ’s metal plate construction provides excellent dimension accuracy and […]
GaN power FETs combine with analog drivers in 650-V half-bridge design
Dialog Semiconductor plc, a provider of highly integrated power management, AC/DC power conversion, solid state lighting (SSL) and Bluetooth® low energy technology, today announced and is demonstrating its first gallium nitride (GaN) power IC product offering, using Taiwan Semiconductor Manufacturing Corporation’s (TSMCs) 650 Volt GaN-on-Silicon process technology. The DA8801 together with Dialog’s patented digital Rapid Charge™ […]
DC link capacitor for IGBT modules
TDK Corporation presents a new EPCOS DC link capacitor that has been specifically designed for the HybridPACK™ 1-DC6 IGBT module from Infineon Technologies. The outstanding features of this component are the six busbar terminals with dimensions that are matched precisely to fit the IGBT module. This multiple contacting produces an excellent current capability while at […]
Low-capacitance TVS diode Arrays work as common-mode filters
Littelfuse has introduced a series of low capacitance TVS Diode Arrays optimized for protecting electronic equipment that may experience destructive electrostatic discharges (ESDs). SP814x Series TVS Diode Arrays (SPA® Diodes) integrate four or six channels of ultra-low-capacitance rail-to-rail diodes and an additional zener diode to safely absorb repetitive ESD strikes above the maximum level specified […]

Potential game changer for prosthetics:
The electroadhesive clutch
Researchers at Carnegie Mellon University have come up with a solid-state clutch they say is three to 30 times lighter than ordinary clutch mechanisms with the same holding force. Consisting of little more than a couple sheets of aluminized Mylar, the clutch consumes 340 to 750 times less energy compared to previous devices while operating […]
