TDK Feed Through CKD series capacitors
feature 3-terminal design with even lower ESL
than Flip Type capacitors. Feed through design
consists of 3-terminal construction where the 3rd
terminal acts as a ground. Unique internal design
allows for low parallel inductance and offer
excellent noise reduction capability for high
speed digital IC decoupling.
CKD Series are offered in a variety of case
size with operating temperature range of -25ºC to
+85ºC and -55ºC to +125ºC. A wide range of
capacitance with rated voltage from 4V to 50V are
available.

Noise
When a pass-through structure is used, the smaller the
distance between the capacitor and the ground, the lower
the ESL. This helps reduce noise from the circuit.

Attenuation Characteristics
It is possible to reduce the number of components with CKD Series capacitor
because one CKD part has similar or better attenuation characteristics as three
standard 2-terminal capacitors.
In high-frequency application, the equivalent series resistance (ESR) and equivalent
series Inductance (ESL) of a capacitor’s internal electrodes and terminal electrodes
become apparent. ESL acts as a hindrance, reflecting the signal current. Feed Thru
Capacitor allow for better filtering and decoupling due to low ESL and ESR.
