Inductor for Low Frequency Circuits
Attention should be paid to potential magnetic coupling effects when using the inductor (coil) as a resonator.
(1) Soldering method
Solder: Use Sn-3.0Ag-0.5Cu solder.
Flux: Use rosin-based flux, but not strongly acidic flux (with

2. Standard Soldering Conditions
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.
Chip inductor (Chip coils) can be flow or reflow soldered.
Please contact Murata regarding other soldering
methods.
