Construction
- Tinned copper lead wire
- High heat exchanged ceramic base
- Tin-plated steel caps
- High stability electric conduction film
- Color ring mark
- Epoxy resin coating
Note: Standard coating is blue epoxy resin paint. Special non-flammable grey or brick red coating is available. For 5W products, non-flammable coating is recommended due to higher surface temperature.
Precautions for Use
- For high resistance values (hundreds of K ohm), the film layer is very thin, potentially reducing reliability, especially in high humidity environments. Ultra-high resistance values are not recommended for high-reliability designs.
- For ultra-high resistance values, consider MG High Voltage Surge Resistors or CHIP Resistors.
- For low resistance and ultra-low resistance applications where temperature coefficient or current capability is critical, consider KN Wire Wound Resistors.
- Precision metal film resistors have a thinner film layer compared to other thin film resistors, making them less resistant to pulses. Avoid using high resistance products in high pulse or continuous pulse circuits.
- The conductive composition is prone to oxidation at high temperatures. Pay attention to surface temperature rise and surrounding heat dissipation for high-power products. Do not use adhesives for fixing or potting, as they can hinder heat dissipation and may cause electrochemical reactions leading to failure.
