The choices vary, from traditional fuses to PPTCs and eFuses, but what is the right choice?

How evolving regulations and emerging technologies are shaping the next generation of secure mobility.

This question came up in a discussion about power electronics failures for which there was initially no viable explanation. Cosmic rays are not an invention by Stanislav Lem or a myth from the Star Wars universe. Cosmic radiation consists of high-energy particles ejected into space in large quantities by stars such as our sun. Our planet's magnetic field deflects most of what travels toward Earth, and only a few high-energy particles enter the Earth's atmosphere.

Chicago, Illinois. Littelfuse, Inc. expanded its NanoT tactile switch family featuring miniature, surface-mounted, waterproof tactile switches, now incorporating new operational force options and top- and side-actuated models. According to the press release, the series is the smallest tactile switch solution available today.

As rechargeable battery technology increases battery charge density and capacity, more and more products are operating on Lithium-ion (Li-ion) battery power.

Littelfuse, Inc. announced an update to its C&K Switches KSC2 Sealed Tactile Switch product line with Precise Electrical Height. The KSC2 series is ideal for surface-mount technology (SMT) and is IP67-rated with 3.5 mm high momentary-action tactile switch featuring a soft actuator.

Chicago, Illinois. Littelfuse, Inc. introduced its LS0502SCD33S, the newest member of the eFuse Protection IC lineup. The design introduces the Single Cell Super Capacitor Protection IC, developed specifically for charging backup power sources under harsh environments. The LS0502SCD33S leverages supercapacitor technology delivering a broad temperature range and offers superior power/energy density. It efficiently manages high operational voltages (above 3 V).
