The US MIL-STD-461 specification manages electromagnetic interference emissions by setting limits on the levels that can be emitted from electrical equipment. This specification also sets regulation to control equipment susceptibility to external noise sources and establishes guidelines for properly measuring the relevant equipment features.

The noise suppression component will be inserted in signal lines for electronic control circuits in automotive applications including car audio, navigation, and battery monitoring systems. Signal transmission paths are often affected by conduction, radiation noise, or other impacts. To control these noises, a chip bead supporting a high-frequency band from several dozens of MHz to several GHz is typically inserted.

One of the factors that greatly determine the performance characteristics of a capacitor is its geometry. The geometry of a typical feedthrough a capacitor differs from that of conventional capacitors. It is this structural difference that gives them their outstandingly good insertion loss characteristics. This low insertion loss is due to a design that ensures that the ground terminal side has zero residual inductance.
