"ꢀThe chip solid EMIFILr incorporates a built-in three-
terminal capacitor, eliminating the lead wire and thereby
increasing the high-frequency performance characteristic.
"ꢀThe T-type chip EMIFILr is a chip EMI suppression filter
with a built-in feed-thru capacitor. The use of ferrite
beads on input and output terminals minimizes
resonance with surrounding circuits.

"ꢀWhatever the situation, 3-terminal construction reduces
residual inductance, thereby substantially improving
noise suppression at frequencies over 10MHz.
A 3-terminal capacitor has a high self resonance frequency than
general 2-terminal type and exhibits effective noise suppression at
high frequency
