Featuring <4.0 mm body diameters, temperature levels from +80 to +150°C, and ±5°C tolerances, PTCSL03 Series provides remote over-temperature sensing in alternative energy, industrial, and consumer applications. Sensors feature max R25 of 120 Ω, max voltage of 30 V, dissipation factor of 5 mW/K, and thermal time constant of 6 s. Consisting of medium-resistivity doped barium titanate ceramic chip with copper-clad steel wire leads, devices offer long-term behavior of ΔT ≤1°C after 1,000 hr.
