2.5±0.2
2.5±0.2
The LQH32C series consists of miniature chip coils
with low DC resistance, high current capacity, and
high impedance characteristics.
These features are made possible by the development of
Murata's innovative automatic winding techniques.
They are excellent for use as choke coils in DC power
supply circuits.

s
Features (LQH32C_11/_21)
1. The low DC resistance means high current and high
inductance.
For inductance ranging from 0.15 micro H to
560 micro H, LQH32C coils have very low DC
resistance.
2. The series exhibit low voltage drops and small
variations in inductance with respect to
temperature rise and DC current level. This makes
them excellent for use as power supply line choke
coils.
3. The series has excellent solder heat resistance.
Both flow and reflow soldering methods can be
employed.
