Passive electronic component types and the need for electrical insulation

SolEpoxy supplies a range of epoxy coating powders developed for electrical insulation of passive electronic devices including resistors, varistors and capacitors. From incredible thermal cycle materials for Class 1 rated Ceramic Capacitors, to low cost epoxy coating powders for film wrap capacitors, SolEpoxy products pioneered this industry and continue to push the envelope for the best performing materials on the market today. Most of the products offered by SolEpoxy for passive electronics have a UL-listing.

Passive electronic components are normally two-terminal components that cannot introduce net energy into a circuit and also cannot amplify a signal (have the ability to produce gain).

Examples of passive components include:

  • Capacitors: Components that store and release electrical charge
  • Resistors: Components that oppose current and pass current in proportion to the voltage.
  • Varistors: Components that pass current when there is too much voltage.
DK18-05 Class 2 & 3 capable epoxy coating powder for ceramic capacitors /varistors and tantalum capacitors 
DK18-05 is a medium-performance, epoxy coating powder developed for Class 2 & 3 ceramic capacitors /varistors and tantalum capacitors.
DK18-0955 is best price-to-performance epoxy coating powder for Class 3 ceramic and film wrap capacitors 
DK18-0955 offers the best price-to-performance for class 3 ceramic and film wrap capacitors. DK18-0955 has excellent pickup and curing at temperatures as low as 110C, making it excellent also for other temperature sensitive devices.
DK18-2100 Class 1 capable epoxy coating powder for automotive power ceramic capacitors and varistors 
DK18-2100 is a high-performance epoxy coating powder developed for Class 1 power capacitors and varistors, which are physically large high power and high voltage devices. On internal tests, DK18-2100 has passed the AEC-Q200 automotive stress test for thermal cycles, meaning that it has endured over 1000 cycles from -55C to +125C without a single crack.
