Metal Oxide Resistors are fixed resistors manufactured using a metal oxide film, typically tin oxide, deposited onto a ceramic substrate. They are designed to provide reliable and stable resistance performance while offering good resistance to heat, moisture, and electrical stress.

Metal oxide resistors are commonly used in power supplies, industrial electronics, automotive systems, appliances, and general-purpose circuits. They are well suited for applications requiring good temperature stability, high voltage capability, low noise, and strong overload and surge resistance. They are available in a wide range of resistance values, power ratings, tolerances, and package configurations.
