MtronPTI uses ECCOSTOCK FFP for Staking Toroidal Inductors in Place

MtronPTI (www.mtronpti.com), a full service manufacturer of frequency control devices sought to encapsulate several toroidal inductors in one of their 250 MHz High Power RF Filters. These inductors (shown after potting below) undergo extreme vibration throughout its lifespan and without being properly staked in place, they would eventually vibrate loose causing the equipment to malfunction.

Toroidal inductors and transformers are electronic components, typically consisting of a circular ring-shaped magnetic core of iron powder, ferrite, or other material around which wire is coiled to make an inductor. Toroidal coils are used in a broad range of applications, such as high-frequency coils and transformers.

ECCOSTOCK® FFP is a low loss, one part, epoxy based free flowing powder that cures to a rigid non-burning syntactic foam. ECCOSTOCK® FFP is designed to infiltrate densely populated electronic packages, readily filling void space around components when vibrated in place. It can be used to stabilize crystal oscillators as well as other delicate components that need to be held in place or thermally protected. It may also be used in machinery operating in high vibration environments to minimize damage to electrical components.

ECCOSTOCK® FFP is extremely lightweight and provides physical support as well as thermal insulation without increasing the weight or affecting the dielectric constant.
