The WS series expands greatly upon the XS and YS offerings by providing increased filtering in the HF through MICROWAVE frequency spectrum from 500 KHz up to 10 GHz. The larger diameter of the WS series means even higher values of capacitance, a rated DC current of 15 Amps, plus 125 VAC/400 Hz ratings are available. Designed to be soldered into a package, bracket or bulkhead (and maintain hermeticity), it is ideal for low to medium impedance circuits where large amounts of capacitance to ground can be tolerated. In the “L” section version an internal ferrite bead element provides both inductance and series resistance (lossy characteristic) which improves insertion loss and provides superior transient performance. Alternate lead lengths or special capacitance values may be ordered. Custom packages or bracket assemblies utilizing this feed thru can be furnished to your specifications.


  • High temperature construction withstands 300°C installation temperatures
  • High purity gold plating provides excellent solderability or compatibility with thermal and ultrasonic wire bonding
  • Meets or exceeds the applicable portions of MIL-F-28861/13
