Splet26. jul. 2024 · Both negative temperature coefficient (NTC) and positive temperature coefficient (PTC) thermistors’ values change as a result of temperature but impact their use differently. For NTC thermistors, as temperature increases, the resistance drops from high to low and allows current to pass through. SpletAerospace thermal switch for commercial and military applications combines small size with robust electrical characteristics and more. 700 Series Thermal Switches. The 700 Series is rooted at the start of the Space Age – this series is a purpose-designed product to support manned and unmanned space applications.

SpletA thermal fuse is a cutoff which uses a one-time fusible link.Unlike a thermal switch which may automatically reset itself when the temperature drops, the thermal fuse is more like an electrical fuse: a single-use device that cannot be reset and must be replaced when it fails or is triggered.A thermal fuse is used when the overheating is a result of a rare … SpletPTC thermistors are heat-sensitive sensors whose resistance increases with temperature, and can be used in almost all areas where a digital temperature measurement is required, … SpletPCT-1000 Programmable Pre-heater The PCT-1000 is a programma-ble preheater that provides users exceptional ability to increase heat capacity with highly controlled ther-mal output. The preheater is ideal for aiding high thermal demand applications including lead-free, multi-layer boards and large ground planes. The PCT-1000 can be used spie optics photonics
