CHIP COILS
for General Use Magnetic Shielded Type LQH3ER Series
LQH3ER Series
s
Features
The LQH3ER series consists of magnetically shielded chip
inductors. Its tight inductance tolerance of +-2%
enables no adjustment of circuit. The shielding
structure eliminates external interference and
facilitates high mounting density.

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.

4) Reworking with Soldering Iron
Preheating at 150°C for 1 minute is required. Do not
directry 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 : 280°C
Diameter of soldering iron end : 3.0mm Max.
Soldering time
: within 3 second
3. MOUNTING INSTRUCTIONS
1) Land Pattern Dimensions
Large lands reduce Q of the mounted chip. Also, large
protruding land areas (bordered by lines having
dimensions 'c' and 'd' shown bellow) cause floating and
electrode cracks.

2) Magnetic Coupling
Since some chip coils are constructed like an open
magnetic circuit, narrow spacing between coils may
cause magnetic coupling.
The LQG and LQM series have a magnetically shielded
structure. The structure makes their coupling coefficient
smaller than that of conventional chip coils.
Magnetic Coupling
