Application Notes

Recommended soldering conditions: Reflow soldering (peak temp. within 260, 10s max; 230+, 40s max). Hand soldering: Tip temp. 40010, 3s+1s/-0s.
Do not use flow soldering.
Handle with care to avoid damaging the sliding part.
Adjust resistance with a driver inserted perpendicularly to the sliding part.
Avoid flux and solder scattering on the resistor surface and sliding contact during soldering.
This product is not washable.
Do not use adhesives for fixing the slider.
Ensure proper insulation if wiring patterns are present beneath the product.
For applications requiring high reliability and safety, implement fail-safe designs (protective circuits, redundant circuits).
Recommended storage conditions: Normal temperature (5-35), normal humidity (45-85% RH). Storage period: 6 months from delivery. Avoid direct sunlight and corrosive gas atmospheres.
