MERITEK
Radial Leaded, Epoxy Dipped Multilayer Ceramic
Capacitors are constructed with a moisture and shock resistant
epoxy coating, and can be supplied in bulk or tape and reel
packaging for automatic insertion in printed circuit boards. They
have a wide range of applications in computers, data processors,
telecommunication, industrial controls and instrumentation
equipment, etc.
