Capacitors

Bridging the gap between batteries and capacitors, Type MEC electrochemical capacitors are said to provide high-capacity storage, long service life, and low maintenance. Capacitance is as high as 100,000 farads; voltage ratings are up to 11V. The components can augment existing batteries or replace batteries in high-power applications, such as starting engines.

Switch

A patented auto-detect feature automatically configures the circuitry of the GMR switch to function as a sinking or sourcing device. The 4-mm solid-state switch senses actuator position, and fits in a track within a cylinder's geometry. Giant magnetoresistive technology enables a response rate of 0.10 msec and low symmetrical hysteresis.
