SURFACE MOUNT INDUCTORS
CHIP INDUCTORS
LQH1C/3C/4C Series
The LQH1C and LQH3C Series are subminiature chip coils
with low DC resistance, high current capacity and high
impedance characteristics. These features are made possible
by the development of Murata Electronics’ own automatic
winding and multilayer techniques. They are excellent for
use as choke coils in DC power supply circuits.
LQH1C
The sub-miniature dimensions (3.2 x 1.6 x 1.8mm) allow
parallel mounting on 2.5mm centers. Despite their small size,
at 0.12 H these coils have a maximum current rating of 970mA.
LQH3C
The low DC resistance means high current and high
inductance.
LQH4C
Low voltage drop and small variations in inductance with
respect to temperature rise and DC current level.
