CHIP COIL
Wire Wound Chip Coil
LQN21A/LQN1A
Series for High Frequency
Small Winding-type Air-core Chip Coil with High Q
value at High Frequencies and Low DC Resistance
The LQN21A/LQN1A series consists of air-core chip coil
using a sub-miniature alumina core as a bobbin. The high Q
value at high frequencies and high self-resonant frequencies
make this coil perfect for use in the high frequency circuits
of communications equipment.
!FEATURES
1. LQN21A series covers inductance range from 3.3nH to
470nH.
2. Their high self-resonant frequency characteristic yields a
high Q value and highly stable inductance at high
frequencies.
3. Low DC resistance design enables to handle higher
allowable current.
4. The series has excellent solder heat resistance.
Both flow and reflow soldering methods can be employed.

Inductance tolerance
T0.5nH
(8.2nH max.),
T5%
(10nH
to 220nH) and
T10%
(270nH to 470nH) are realized.
The sub miniature dimensions (2.0Z1.5mm) allow high
density mounting.
隆LQN21A
(Tight inductance tolerance)
Tight inductance tolerance of
T2%
is available.
隆LQN21Axxxx44
LQN21Axxxx44 using thick wire (f0.12mm) has higher Q
value than existing LQN21A series. Low DC resistance
design enables to handle higher current.
LQN21Axxxx44 covers inductance range from 2.7nH to
27nH.
隆LQN1A
Miniature size (3.2Z1.6Z1.8mm) allows parallel mounting
at 2.5mm pitch.
