Vishay Intertechnology has introduced a series of mini radial-leaded positive temperature coefficient (PTC) sensing thermistors. Featuring <4 mm body diameters, a wide range of well-defined temperature levels from 80 to 150°C and standard ±5°C tolerances, devices in the Vishay BCcomponents PTCSL03 series are designed to provide compact remote overtemperature sensing in alternative energy, industrial and consumer applications.
The devices provide good long-term behaviour of ΔT ≤1°C after 1000 h for overtemperature protection and control in power supplies, power inverters, motor drives, lighting drivers, smart fuse boxes and pump motors. The sensors feature maximum R25 of 120 Ω, maximum voltage of 30 V, a dissipation factor of 5 mW/K and a fast thermal time constant of 6 s.
The devices consist of a medium-resistivity doped barium titanate ceramic chip with copper-clad steel wire leads. With rugged, durable construction, the sensors feature a high-temperature silicone coating and are also available as bare pellets on request. The RoHS-compliant devices are offered in tape-on-reel and bulk packaging.
