Standard Chip Coil LQH1N/LQH3N/LQH(N)4N Series

CHIP COIL

3

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.

Small Tolerance Chip Coil

LQS33N

Series for Oscillation Circuits

CHIP COIL

12

High Q, Magnetically Shielded Chip Coil with Tight Inductance
Tolerance (T2%), Perfect in Oscillation Circuits

The LQS33N series consists of closed, magnetically
shielded chip inductors wound on ferrite bobbins developed
by Murata.
Their high Q value virtually eliminates interference with
nearby circuits. This, combined with their tight inductance
tolerance, makes these chip inductors excellent in resonant
circuits.

!FEATURES

1. The coil's outstanding stability yields a reduction in

inductor tolerance to within T2%.

2. Its high Q (typically greater than 80) is present at all

inductance values and is the basis of this chip coil's
outstanding low loss circuit characteristics.

3. The ferrite core shielding structure both eliminates

external interference and facilitates high mounting
density.

4. Small inductance variation with respect to temperature

change makes these coils applicable in traps or LC filters
for stable frequency characteristics.

5.

This series is thin and compact, with a thickness of merely

1.8mm.
