Ohmite's 40 Series resistors are a cost-effective solution for applications requiring conformal coating and wirewound construction. These resistors are characterized by their low temperature coefficients, excellent thermal shock resistance, and durability. They are widely used in commercial, industrial, and communications equipment where stability and reliability are essential. The conformal silicone-ceramic coating provides enhanced protection against moisture and contaminants, extending the lifespan of the resistor. Available in both 1% and 5% tolerance options to meet diverse application needs.
