Miniature Solder-In EMI Filters

Spectrum Control's line of miniature solder-in EMI filters have a hermetic seal on one end for through-hole sealing between compartments, allowing it to be soldered into a package, bracket, or bulkhead while maintaining hermetically. The high-temperature construction of these EMI filters meets military requirements for solderability and resistance to soldering heat. The high-purity gold plating provides excellent compatibility with gold bonding techniques. Available in MIL-C-11015 versions, custom designs, and RoHS compliant versions.
