Fusible resistors vs fuses
Safety standards often dictate what component provides the best protection against overcurrents. Todd Phillips, Saad Lambaz • Littelfuse, Inc. Most people would probably agree that the time it takes to recharge their cell phone, gaming console, or tablet computer is both inconvenient and annoying. Faster charging requires a more powerful charger or power supply. The […]
Protecting autonomous vehicle control circuits
The subsystems that make up an autonomous vehicle should be bullet-proof when it comes to electrical interference and transients. James Colby, Prasad Tawade Littelfuse, Inc. Those who follow autonomous vehicle technology are usually well aware of its benefits. But the safety and convenience autonomous vehicles offer can only come if the vehicle electronics is reliable […]
The try-before-you-buy route to energy efficient power design
Evaluation platforms help pick SiC components in power conversion circuits. Xuning Zhang, Levi Gant, Littelfuse, Inc. The quest for greener energy production and consumption has put a premium on high-efficiency power circuitry. In that regard, many modern power supplies and converters operate at much higher voltages that allow use of lower currents to minimize I2R […]
Tiny, dual-channel PPTC protects network and telecom equipment
Littelfuse, Inc. announced a new series of 250V Telecom PPTCs designed to help make telecom and network equipment more reliable. The TSM250-130 series protects against power cross and induced power surges as defined in ITU, Telcordia GR1089 and IEC 62368-1. Because it combines two resistance-matched PPTCs in a single surface-mount housing, it reduces the board […]
High-temperature thyristors handle up to 250 Vrms
Five new series of high-temperature Alternistor TRIAC switching thyristors are designed for use as semiconductor switches in appliances and equipment powered by line AC voltages up to 250 VRMS. Available in five compact, surface-mount and through-hole packages, these components expand the Littelfuse TRIAC product line by making high 150°C maximum junction temperature devices available in […]

The thyristors are designed for use as semiconductor switches in appliances and equipment powered by line AC voltages up to 250VRMS. Available in five compact, surface-mount and through-hole packages, these components expand the Littelfuse TRIAC product line by making high 150°C maximum junction […]
Low-capacitance TVS Diode arrays protect 10GbE high-speed differential data lines from discharge and surge events
Littelfuse, Inc. introduced a series of low capacitance TVS Diode Arrays (SPA Diodes) optimized to protect high-speed differential data lines from electrostatic discharge (ESD), cable discharge events (CDE), electrical fast transients (EFT), and lightning-induced surges, keeping network communications reliable by safeguarding signal integrity. The SP3384NUTG Series can protect up to four channels against up to […]
TVS diodes provide 8-kW peak pulse power dissipation in a space-saving package
A new series of higher surge TVS Diode products come in an DO-214AB package. The 8.0SMDJ series is optimized to protect sensitive electronic equipment from transient voltage induced by lightning and other voltage events. Because it combines up to 8,000 W of peak pulse power dissipation in a compact DO-214AB SMC package, the 8.0SMDJ series […]
