Notice of Chip Coil
3. Standard Soldering Conditions
1Soldering
Method
Chip coils can be flow or reflow soldered. (LQS33N,
LQS66C and LQP11A should only be 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 LQP10A/11A, LQG10A/11A
and LQW1608A series.
2Soldering
Temperature and Time
Solder within 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.

3Solder
and Flux
Solder : Use H60A, H63A, (JIS Z 3282) or equivalent.
Use solder paste equivalent to H60A for
LQP10A/11A and LQG10A/11A.
Flux : Use rosin-based flux, but not strongly acidic flux
(with chlorine content exceeding 0.2wt%).
Do not use water - soluble flux.
5Reworking
with Soldering Iron
Preheating at 150D for 1minute is required. Do not
directly touch the ceramic element with the tip of the
soldering iron. The reworking soldering conditions are as
follows.
Soldering iron power output
: 30W max.
Temperature of soldering iron tip : 280D
Diameter of soldering iron end
: 3.0mm max.
Soldering time
: within 3 sec.
