PART NUMBERING SYSTEM
SPECIFICATIONS
The chip coil LQH/LQN Series comprises subminiature chip
inductors wound on a special ferrite core made possible by an
automatic winding technique developed by Murata Electronics.
These inductors have a high Q at high frequencies and
low DC resistance, making them suited for enhancing the
performance of electronic circuits in video, communications
and audio equipment.
LQH1N
The sub-miniature dimensions (3.2 x 1.6 x 1.8mm) allow
parallel mounting on 2.5mm centers. This series is suitable
for portable audio-visual equipment.
LQH3N
High Q value makes the series suitable for circuits up to100MHz
in frequency. This series is excellent for video equipment.
LQH(N)4N
This series is available with high inductance values and high
current capacity. At 10H, up to 450mA designs are possible,
resulting in excellent performance when the series is used as
a choke coil.
Available as standard through authorized Murata Electronics Distributors.
