o This capacitor type EMI suppression filter has a large

noise suppression effect at frequencies ranging from a

few MHz to hundreds of MHz. This type of filter is used

widely as a universal, high performance EMI suppression

component.

o Three-terminal construction reduces residual inductance,

thereby substantially improving noise suppression at

frequencies over 10MHz.

A three-terminal capacitor has a higher self resonance frequency

than a general two-terminal type and exhibits effective noise

suppression at high frequency.
