Power Choke Coil
Series: PCC-F179F (S1)
Thin, light and high power type made possible by
our original unique winding and core shape technology
Suitable for large current demands of PC servers
■ Features
■ Recommended Applications
● PC(Server) DC/DC converters for driving CPU at high
speed
● High power type (Saturation currents up to 42.3 A)
Its low loss is due to our low resistive technology
● Thin (9.0 mm height), Light weight (9.9 g)
● Low leakage flux
● Thin type on-board power supply module for converters
(30 to 80 W)
Also suitable as a smoothing choke coil

Notes: Inductance is measured at 100 kHz
See Figure 1 for the following:
1) For the definition of L0 & L1 , please refer to the next page.
2) Saturation current ( I sat) is the current value that inductance (L1) decreases to 80% of initial value
3) Case heating current is the value of the current at which the temperature of the coil case rises
40 degrees Celsius above its initial temperature with T(ambient)=25C
