Littelfuse has introduced the LST Varistor series. Constructed with a proprietary, thermally protected varistor technology (TMOV), developed by Littelfuse, this new varistor incorporates both a built-in thermal disconnect function and electric arc shield. This combination provides additional robust protection to prevent catastrophic failure and fire hazard even under the extreme circumstances of abnormal overvoltage conditions or varistor en...

Littelfuse has introduced an expanded reed relay product portfolio that extends voltage capabilities to include AC ratings, supports AC or DC loads up to 300 Vdc, and provides input/output isolation voltage 2,500 VRMS. These miniature reed relays are available in single In-line (SIL) and dual-in-line (DIL) packages.

Littelfuse has announced the PLA172P OptoMOS Relay, an 800V normally-open single-pole 6-pin solid-state relay (SSR). It is the first solid-state relay in the Littelfuse product portfolio that comes with guaranteed electrical parameters at 105°C ambient operating temperature.

Littelfuse has introduced a new arc-flash knowledge centre online for engineers, electricians, maintenance workers, and others creating a safer electrical environment. The resource portal helps workers protect critical infrastructure by providing arc-flash information on causes, mitigation and incident energy calculations as well as white papers, videos and case studies.

Littelfuse has announced the ITV Series, a three-terminal, surface mountable li-ion battery protector designed to guard against the damage caused by both overcurrent and overcharging.

Littelfuse has announced the expansion of its SPXI series in-line solar fuses to include 35 to 60 amperage models. Designed to integrate into in-line assemblies within a wire harness, these 1,500V DC solar fuses protect photovoltaic (PV) installations from overloads and short circuits to minimise damage to solar panels.

Littelfuse has announced the Gate Drive Evaluation Platform (GDEV). The new evaluation platform helps designers evaluate SiC MOSFETs, SiC Schottky diodes, and other peripheral components like gate driver circuitry, so that they can better understand how silicon carbide technologies will behave in converter applications under continuous operating conditions.

Littelfuse has announced an additional five series of high-temperature Alternistor TRIAC switching thyristors. The thyristors are designed for use as semiconductor switches in appliances and equipment powered by line AC voltages up to 250VRMS.

A new series of low capacitance TVS Diode Arrays (SPA Diodes) has been introduced by Littelfuse. The series is optimised 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.  

Littelfuse has 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.
