LQH66S Series
6.3±0.3
6.3±0.3
s
Features
The LQH66S series are choke inductors which have
achieved low direct current resistance, large current
capacity and large inductance by using high
performance thick wire winding technology.
Because the LQH66S series has a magnetic shielded
construction, it can be mounted in high density
without interference occuring between peripheral
components. They are optimum for use as choke
inductors in DC/DC converters and DC power supply
circuits.
