Precision Thick Film Chip Resistors
n Recommended Land Pattern
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).

áReflow soldering shall be two times maximum.
áPlease contact us for additional information when
used in conditions other than those specified.
áPlease measure temperature of terminations and study
solderability for every kind of solder and board, before
actual use.

Safety Precautions
1. If transient load (heavy load in a short time) like pulse is to be applied, carry out an evaluation
and confirmation test with the resistors actually mounted on the board.
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
seconds and up to 350 ¡C).
4. Avoid physical shock to the resistor and nipping of the resistor with hard tool ( pliers or tweezers) as it may
damage protective coating or the body of the resistor and may affect its performance.
Design, Specifications are subject to change without notice. Ask factory for technical specifications before purchase and/ or use.
Whenever a doubt about safety arises from this product, please inform us immediately for technical consultation without fail.
