    Metal film resistor applications

    Tips: Can metal film resistors be used in high-temperature environments?

    Metal film resistors are commonly used in electronic circuits due to their high precision, stability, and low noise. However, their ability to withstand high-temperature environments depends on the specific type of metal film resistor and the temperature range in question.

    In general, metal film resistors can operate reliably at temperatures up to 155°C, which is the maximum operating temperature for many standard metal film resistors. Beyond this temperature, the resistor's performance can degrade, and it may even become damaged.

    There are specialized metal film resistors designed to operate at higher temperatures, such as high-temperature thin-film resistors. These resistors use special materials and construction techniques to withstand temperatures up to 300°C or higher. However, they can be more expensive and less widely available than standard metal film resistors.
