  • Higher self-resonant frequency and lower equivalent series induc- tance than CD17 and CD18
  • Low impedance to beyond 1 GHz
  • Replaces other 0.1” lead-spacing capacitors
  • Cool operation—Typical Qs > 2000
  • Shockproof and delamination free
  • Near zero capacitance change with frequency and temperature
  • 100,000 V/µs dV/dt capability minimum
  • Zero capacitance change with voltage 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. For RoHS compliant add the letter F at the end of the part number.

A typical test setup is below. 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.
