Characteristics and Applications of EMI Filters

Welded EMI filter

Welded EMI filters are ideal for small installation spaces.

Application: Mainly used for filtering signals, data lines, and AC power lines.

Telecommunications equipment, transmission equipment, microwave filters, industrial computers, composite circuit filter components;

Small size: efficient use of space.

Rated voltage: up to 1000VDC;

A variety of circuit structures: C-type, Pi-type, L-type circuits can be provided;

High temperature structure: can prevent backflow during installation.

Certification: Filters available for MIL-F-15733QPL and MIL-C-11015 (CK99) certification.

2) Resin sealed threaded EMI filter

Resin seal bolt type EMI filter with the matching nut and washer can be easily installed to the through hole position;

Resin sealing at both ends of the sturdy housing provides good environmental protection.

Application: Mainly used for filtering signals, data lines, and DC power lines; among them, micro-extrusion installation or screw installation is an ideal choice for applications when welding is not suitable, suitable for microwave and other high-frequency applications;

Voltage: up to 2500VDC/250VAC

Certification: Available for MIL-F-15733 certified products

Circuit structure: C type, L type, Pi type

3) High current and high voltage resin sealed EMI filter

Application: High current filters are mainly used in high current switching power supplies and DC charging systems.

High-voltage filters are mainly used in high-voltage power supplies, and are easy to install with strong bolt-type structures.

Features: High current up to 100Amps (customized for special requirements)

Voltage: up to 3000VDC and 2500VAC (customized for special requirements)

4) Glass-sealed high-performance EMI filter

This series of filters is sealed with glass and has excellent EMI filtering performance. For those who still require high reliability filtering in harsh environments, this product is the best choice for broadband high-performance EMI filtering from 10KHz to greater than 10GHz. The glass-sealed series is highly moisture-proof, corrosion-proof, and resistant to other harsh environments that may be encountered in military applications.
