Competing brands of batteries can have substantially different dimensional specs. Where this dimensional tolerance has an impact is in the battery holder. A coin cell holder must be designed so it can handle normal height variances while at the same time, not accept batteries of a different type. Obviously, the battery holder can’t have a […]

Better barriers make lithium batteries hard to beat
An advanced barrier between the electrodes in lithium-ion batteries could help head off fires and overheating that occasionally arises in laptops or industrial applications. The barrier uses nanofibers extracted from Kevlar. The barrier helps minimize the growth of metal tendrils on battery electrodes that can otherwise lead to electrical shorts. In normal battery operation, there […]
Small batteries pack big wallop for wireless devices
by Sol Jacobs, Tadiran Batteries Battery makers have devised chemistries that put a lot of energy in a tiny volume. Generally speaking, every penny counts when it comes to designing devices for a mass consumer market. That’s one reason smartphones use relatively inexpensive, rechargeable lithium polymer batteries for power. Constructed from a thin, flexible material, […]
DIN-mounted surge protector
L-com Global Connectivity, a designer and manufacturer of wired and wireless connectivity products, announced that they have released a new DIN mountable 3-stage lightning protector to protect RS232 and industrial control lines. The HGLND-D2-12 is a high performance 3-stage lightning protector that provides superior protection of differential or balanced digital or analog lines from transients […]
20-A step-down regulator optimized for low V IN/low V OUT
Linear Technology Corporation introduces the LTM4639, a 20A DC/DC step-down µModule® (micromodule) regulator capable of converting 2.5V to 7V main-power system rails to point-of-load voltages as low as 0.6V with optimum efficiency.
