Thermal Fuses
Thermal fuses are generally the most cost effective solution for limiting an over-temperature condition in customer applications but are the least versatile type of device as they contain a fuseable link which operates one time and then must be replaced. These devices are commonly referred to as "One-shots" or one time use type control. These devices are good to use either as a back-up device to a resettable type device or when a catastrophic occurrence is possible and you would want the product to totally shut-down.
