Ceramic Feedthrough Cap

Feed through capacitors are fitted to the metal case of the rf module on holes where the wires enter the system.

Ceramic feedthrough cap.

Inside every emi filter is a ceramic feedthrough capacitor. Tubular feedthrough capacitors are widely used in high frequency filtering applications. Mouser offers inventory pricing datasheets for feed through capacitors. These applications include requirements for high voltage capacitors.

This circuit type will provide an insertion loss slope after the cutoff frequency of approximately. Number of applicable products. What is feed through capacitor electronics components symbols feed through capacitors are originally designed for dc power line in rf module or system. Surface mount feedthrough filters avx smd feedthru filters are an easy way to achieve broad band emi reduction in a small smd package.

1 0mm x 0 5mm eia 0402 1 6mm x 0 8mm eia 0603 thickness. Smd feedthru filters can help reduce cost designs by eliminating some types of l c filters increasing system reliability and saving valuable pcb area. A ceramic capacitor is a fixed value capacitor where the ceramic material acts as the dielectric it is constructed of two or more alternating layers of ceramic and a metal layer acting as the electrodes the composition of the ceramic material defines the electrical behavior and therefore applications. It passed through the dc and low frequency signals but blocks the rf energy.

In practical use the. Feedthrough terminal ground electrode feedthrough capacitor 80 40 60 20 0 1 5 10 50 100 500 1000 2000 frequency mhz insertion loss db feedthrough ceramic capacitor df553. Feed through capacitors are available at mouser electronics. Due to their cylindrical design the insertion loss of these capacitors is uniform over a wide range of temperatures.

Our ceramic capacitors are ideal for emi rfi suppression filters medical implantable devices commercial and. For these capacitors the inductance is in the series arm of the filter. Tubular ceramic feedthrough capacitors. A c circuit consists of a single feedthrough capacitor on a center conductor fig.
