CHIP COIL
Standard Chip Coil LQH1N/LQH3N/LQH(N)4N Series
Wire Wound Chip Coil with High Q Value
at High Frequencies and Low DC Resistance
The chip coil LQH/LQN series consists of miniature
chip inductors wound on a special ferrite core and are
made possible by an automatic winding technique
developed by Murata. These inductors have a high Q at
high frequencies and low DC resistance, making them
very well suited to enhancing the performance of
electronic circuits in video, communications, and
audio equipment.
!FEATURES
1. There are three different inductor types: the
LQH1N,LQH3N and LQH(N)4N series. These three series
cover a wide inductance range (from 0.1µH to 2.2mH).
2. The series has outstanding frequency characteristics and
a high Q value at high frequencies.
3. The low DC resistance permits high current flow.
4. The series has excellent solder heat resistance. Both flow
and reflow soldering methods can be employed.
¡LQH1N
Miniature size (3.2Z1.6Z1.8mm) allows parallel
mounting at 2.5mm pitch. The series is suitable for
portable audio-visual equipment.
¡LQH3N
A high Q value makes this series suitable for circuits
up to 100MHz in frequency. The series is excellent for
video equipment.
¡LQH(N)4N
This series offers high inductance values
and high current capacity. At 10µH, up to 450mA
designs are possible, resulting in excellent
performance when the inductors are used as choke coils.
