Suitable for large current demands of PC servers
High power type (Saturation currents up to 42.3 A)
Its low loss is due to our low resistive technology
Low leakage flux
Thin, light and high power type made possible by
PC(Server) DC/DC converters for driving CPU at high
Also suitable as a smoothing choke coil
0 1
2) Saturation current ( I sat) is the current value that inductance (L1) decreases to 80% of initial value
40 degrees Celsius above its initial temperature with T(ambient)=25C
Notes: Inductance is measured at 100 kHz
See Figure 1 for the following:
our original unique winding and core shape technology
Thin type on-board power supply module for converters
