Chip Coils
High-frequency Winding Type LQW2BH/LQW31H Series
1.5±0.2
1.5±0.2
The LQW2BH 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
2.0±0.2
1.5±0.2
frequency circuits of communications equipment.

■ Features
1. LQW2BH series covers inductance range from 3.3nH to
470nH.
2. Their high self-resonant frequency characteristic
0.5 min
0.5 min
0.5 min
(in mm)
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.
• LQW2BHN_J01, K01
Inductance tolerance +-0.5nH (8.2nH max.), +-5%
(10nH to 470nH) is realized. The sub miniature
dimensions (2.0x1.5mm) allow high density mounting.
• LQW2BHN_G01 (Tight inductance tolerance)
Tight inductance tolerance of +-2% is available.
• LQW2BHN_11
LQW2BHN_11 using thick wire (0.12mm in diameter)
has higher Q value than existing LQW2BH series.
Low DC resistance design enables to handle higher
current.
LQW2BHN_11 covers inductance range from 2.7nH to
27nH.
■ Applications
High frequency circuit in telecommunication equipment,
such as DECT, PHS, PCS, PCN, GSM and CDMA.
Impedance Matching -- Power-AMP Module (PA)
SAW filter
