Resistor Units
Resistance Explanation: 1K = 1,000 (1K equals 1 thousand ohms)
1M = 1,000,000 (1M equals 1 million ohms)
RI80 High-Voltage Resistor
Features This product uses more than 95% high-quality ceramics. The resistor film layer is made of noble metals such as silver, palladium, and platinum. It is sintered at a high temperature of 850°C. It has good thermal conductivity and stable electrical performance. The lead terminals are made of tinned copper wire or brass. The glass enamel medium is encapsulated and can be used in air, paint, and epoxy resin.
