EMI/RFI Filters

Overview

Military, Medical and Communications Applications

Through its strategic partnership with Instec Filters, Gowanda now offers EMI/RFI filters which suppress electromagnetic interference using capacitive and inductive elements. The capacitive elements shunt the interference to ground while the inductive elements raise the impedance of the line. The robust design of the filters enable them to be used in demanding situations and harsh environments, including military, medical and communications applications.

Features

Miniature Designs

• For applications where larger bolt-style simply won’t fit
• Gold plated feedthrough/filters available in solder-in or press-fit styles
• Feedthru’s can be mounted on 0.200 inch (5.1 mm) centers if needed
• Can also be supplied as pre-assembled filter plates

Hermetic Construction

• Hermetic construction allows them to function in harsh environments
• Circuit designs range from basic C-filter configuration to multi-segment configurations such as T-T filter
• More complex configurations enable steeper frequency cutoffs to be achieved
• High-temperature versions can operate in down-hole applications

Upscreening & Pb-Solder

• Gowanda offers EMI filters assembled with HMP solders (unless Pb-Free is specifically requested)
• These meet the rigors of military, aerospace, and other HIREL applications
• Upscreening is available to MIL-PRF requirements
• Gowanda will quote and build to most customer Source Control Drawings
