Filtered AC Inlet Performs at High Frequencies up to 1 GHz

 

The 5150 Series of AC Filtered Inlets from Schurter utilizes X2Y® filter technology. These devices are characterized by broadband suppression properties to 1 GHz in tandem with a simple and universal input. Unlike previous products that used X2Y® but were limited to DC applications, the 5150 Series provides EMI protection for AC power input. X2Y® combines the X and Y capacitors … [Read more...]

Line of Small Shielded Chambers Targets Pre-Compliance Test Needs

 

A new line of small fully anechoic chambers from Netherlands-based Comtest meets a growing need for pre-compliance testing of small products. The chamber design is based on Comtest’s Pan-Shield shielding panels that provide high shielding effectiveness over a wide frequency range. Additional RF absorbers within the chamber prevent reflections from the metal walls that could … [Read more...]
