Type CD4
High-Frequency, Mica Capacitors
Ultra-High-Frequency Capacitor for CATV and RF Applications 0.1″ Lead Spacing
Nearly the textbook ideal capacitor for high-frequency
applications, Type CD4 is rock stable over its full tempera-
ture and voltage range. Higher self-resonant frequency
and lower equivalent series inductance makes CD4 even
better than CD17 and CD18 for high-frequency applica-
tions. 0.1” lead spacing means CD4 can replace ceramic
capacitors on printed circuit boards.

Typical Performance Curves
Insertion Loss
Over the frequency range of 100 MHz to 1 GHz
the insertion loss in a balanced 50 Ω or 75 Ω sys-
tem is flat ±0.2 dB. A typical test setup is below.
Insertion Loss vs. Frequency for
CD17FC621JO3, 75 Ω System
Choosing CD4, CD16, CDV16, CD18 or CDV18
While insertion loss is flat within ±.2dB through 1 GHz,
you may be able to avoid the small notch by changing
the capacitor type to fit your capacitance. See table at
right.
