Precautions
Use of Chemicals: Avoid contact with ammonia, amines, alkali solutions, aromatic hydrocarbons, ketones, esters, and halogenated hydrocarbons as these can adversely affect the polycarbonate resin used.
Use of Flux: Avoid using water-soluble flux during soldering, as it may negatively impact molding materials and metal components.
Soldering: Prevent molten solder from flowing onto the upper surface of the PC board to avoid imperfect contacts.
Circuit Configuration: Recommended for voltage adjustment (Fig. A). When used for current adjustment (Fig. B), confirm performance under actual operating conditions due to potential influence from contact resistance.
Residual Resistance: Standard construction includes a sulfurization-resistant film over silver electrodes. Contact the manufacturer 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.
Low Temperature Operation: For applications in low-temperature environments, customized products with smoother rotary movements can be provided upon request. Please specify this requirement when ordering.
