Vishay BCcomponents PTCSL03 PTC thermistors

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.
