Leaded Power Chokes - CPUD Series
CPUD Series
CPUD series is designed for low RDC and ultra large current application.
Its assembly model magnetic shielded type is suitable for high-density
mounting and ultra low buzz noise. Soldering conditions can be easily
confirmed when mounting onto the board.
Features
Excellent for power line DC-DC conversion applications
Shielded construction
Low DCR/ uH, in this package series
Handle high transient current spikes without saturation
Ultra low buzz noise, due to composite construction
Applications
Excellent for power line DC-DC conversion applications used in power
switching, personal computers and other handheld electronic
equipment
