Designed for use in line voltage applications, the polymeric positive temperature coefficient devices are rated at 240 Vac, permitting maximum voltages of up to 265 Vac. The thermally active devices can help protect against both over-current and over-temperature faults on the primary side of power supplies and transformers.

The LVR devices are available in straight-lead or kinked-lead configurations, and can be supplied in tape-and-reel packaging for compatibility with high-volume assembly. Pricing starts at $0.25 each for 250,000-unit per year volumes. Samples are available now, and delivery lead-time is 10 weeks ARO.
