Component Specifications

Definition
Terminals and pins in feedthrough filters are specialized electrical connectors designed to pass signals or power through shielding barriers while providing electromagnetic interference (EMI) filtering. These components typically consist of conductive metal elements that connect internal filter circuits to external wiring, often incorporating capacitive or inductive elements directly within the terminal structure to filter unwanted high-frequency noise. They maintain electrical continuity while preventing electromagnetic interference from passing through the filter housing, making them critical for signal integrity in sensitive electronic applications.
Working Principle
Feedthrough filter terminals/pins operate by providing a conductive path through a shielded enclosure while incorporating passive filter elements (typically capacitors or LC networks) that create a low-impedance path to ground for high-frequency noise. The terminal's construction creates a pi-filter configuration where the pin itself forms part of the filtering circuit, attenuating electromagnetic interference by shunting unwanted frequencies to the filter's ground connection while allowing desired signals to pass through with minimal attenuation.

Copper alloys (brass, beryllium copper, phosphor bronze) with gold, silver, or tin plating; stainless steel for corrosion resistance; ceramic or glass insulators; dielectric materials for capacitive elements

Frequently Asked Questions

What is the difference between feedthrough terminals and regular terminals?

Feedthrough terminals incorporate filtering elements (typically capacitors) within the terminal structure to provide EMI suppression, while regular terminals only provide electrical connectivity without filtering functionality.

How do I select the right feedthrough terminal for my application?

Consider current rating, voltage requirements, frequency range of noise to be filtered, insertion loss specifications, mounting type, environmental conditions, and compliance with relevant industry standards.

Can feedthrough terminals be used in high-vibration environments?

Yes, many feedthrough terminals are designed with mechanical locking features, rugged construction, and vibration-resistant materials specifically for automotive, aerospace, and industrial applications.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
