1. Standard Land Pattern Dimensions
A high Q value is achieved when the PCB electrode land pattern is designed so that it does not project beyond the chip
inductor (chip coil) electrode.

2. Standard Soldering Conditions
(1) Soldering method
Chip inductor (Chip coils) can be flow or reflow soldered.
Please contact Murata regarding other soldering
methods.
As for LQG, LQP, LQW04A/15A/18A/21H/2BA/2UA series,
please use reflow soldering.
Solder: Use Sn-3.0Ag-0.5Cu solder.
Flux: Use rosin-based flux, but not strongly acidic flux (with
chlorine content exceeding 0.2wt%).
Do not use water-soluble flux.
The flux used for LQW04/15/18/21/2BA/2UA series
should use the rosin-based flux that includes middle
activator equivalent to 0.06wt% to 0.1wt% chlorine.
For additional mounting methods, please contact Murata.
