3. Mounting Instructions
Preheating at 150 C for 1 minute is required. Do not
directly touch the ceramic element with the tip of the
soldering iron. The reworking soldering conditions are as
follows:
Large lands reduce Q of the mounted chip. Also, large
protruding land areas (bordered by lines having
dimensions 'c' and 'd' shown) cause floating and
electrode leaching.
Since some chip inductors (chip coils) are constructed
like an open magnetic circuit, narrow spacing between
inductors (coils) may cause magnetic coupling.
LQM, LQH66S and LQH_P series have a magnetically
shielded structure. The structure makes their coupling
coefficient smaller than that of conventional chip
inductors (chip coils).
PCB should be designed so that products are not
subjected to the mechanical stress caused by warping
the board.

Products should be located in the sideways direction
(Length: a<b) to the mechanical stress.
The electrode part of the product should be located
like the picture to the mechanical stress.
