In case of flow soldering, the land width must be smaller than the Chip Resistor width to control the solder amount
properly. Generally, the land width should be 0.7 to 0.8 times (W) of the width of chip resistor. In case of reflow soldering,
solder amount can be adjusted, therefore the land width should be set to 1.0 to 1.3 times chip resistor width (W).

1. If transient load (heavy load in a short time) like pulse is to be applied, carry out an evaluation
When a load of more than the rated power is applied under load condition at steady state, it
could impair performance and/or reliability of the resistor.
Never exceed the specified rated power.
2. Chlorine type or other highly-reactive flux is not recommended. Residue could affect performance or reliability of
the resistors.
3. When using a soldering iron, never let the tip of the soldering iron touch the body of the chip resistor. When
using a soldering iron with a tip at a high temperature, solder for as short time as possible (no more than three
