Features
1. High-Q,stable inductance in high frequency is
achieved by the unique low-capacitance structure.
It is suitable for mobile communication equipment.
2. The small size of LQG15H (1.0x0.5x0.5mm) is ideal for
small mobile equipment.
3. The external electrodes with nickel barrier structure
provide excellent solder heat resistance.

Expressed by three figures. The unit is micro-henry (µH). The first
and second figures are significant digits, and the third figure
expresses the number of zero which follow the two figures. If
there is a decimal point, it is expressed by capital letter "R". In
this case, all figures are significant digits. If inductance is less
than 0.1µH, the inductance code is expressed by combination of
two figures are capital letter "N", and the unit of inductance is
nano-henry (nH).
Capital letter "N" indicates the unit of "nH", and also expresses a
decimal point. In this case, all figure are significant digits.

2. STANDARD SOLDERING CONDITIONS
1) Soldering method
Chip coils can be flow or reflow soldered.
Please contact Murata regarding other soldering
methods.
The volume of solder can cause minor fluctuations in
inductance value. Therefore, carefully control the amount
of solder when soldering the LQG15H/18H, LQP03T and
LQP15M series.
2) Soldering Temperature and Time
Solder whithin the temperature and time combinations
indicated by the slanted lines in the following graphs. If
soldering is repeated, please note that the allowed time
is the accumulated time.
Solder : Use H60A,H63A(JIS Z 3282) or equivalent.
Use solder paste equivalent to H60A for
LQP03T/15M and LQG15H/18H.
Flux : Use rosin-based flux, but not strongly acidic flux.
(with chlorine content exceeding 0.2wt%)
Do not use water-soluble flux.
