PRECAUTIONS
Use of chemicals: Avoid contact with ammonia, amines, alkali solutions, aromatic hydrocarbons, ketones, esters, and halogenated hydrocarbons as they may adversely affect the polycarbonate resin used.
Use of flux: Avoid using water-soluble flux during soldering to prevent adverse effects on the potentiometer's materials.
Soldering: Avoid wiring and soldering methods where molten solder flows onto the upper surface of the PC board to prevent imperfect contacts.
Recommended circuit configuration: Recommended for voltage adjustment. If used for current adjustment, confirm performance under actual operating conditions due to potential influence from contact resistance.
Residual Resistance: Standard units have a protective coating over silver electrodes for sulfurization resistance. Contact us for low residual resistance requirements.
Dew condensation: Avoid use in conditions where dew or water drops may form on the resistor surface to prevent reduced insulation or short circuits.
Operation at Low Temperature: For low-temperature environments, customized products with comfortable rotational feel are available upon request.
