C and Pi Filter Connectors – For Improved Signal Quality
Our Micro-D filter connectors serve double duty by also eliminating unwanted high-frequency noise. These connectors feature a precision milled aluminum shell and thermally conductive epoxy potting to prevent damage to filters during soldering. Configuration options include vertical and 90° printed circuit board orientations as well as time and cost saving solutions such as prewired pigtail filter connectors and in-line filter adapters. Glenair Micro-D connectors are in stock and available for immediate shipment.
Glenair Filter Micro-D connectors are low-pass filters, transmitting DC and low frequency signals while attenuating unwanted high frequency noise. These connectors are available with C filter elements or Pi filters. The filter substrates are constructed with a ceramic planar capacitor array.
Glenair Filter Micro-D's meet the demanding performance requirements of MIL-DTL-83513, except for a reduction in the dielectric withstanding voltage rating to 250 volts DC (higher voltages available on request). The TwistPin contact system assures superior performance in the most demanding applications.
- C Filter
Single capacitor with low self inductance. This configuration is generally used to attenuate high frequency signals. The simple design allows high-frequency EMI to discharge to ground via the surrounding electromagnetic field. C filters occupy the least amount of space and offer lower cost compared to other filter types. - Pi Filter
Dual capacitors with a ferrite inductor positioned between them. The Pi filter provides excellent high-frequency performance due to its sharper rolloff.
