PFRX.135 Description

Short technical summary and product information.

The Schurter PFRX.135 is a polymeric PTC resettable fuse designed for overcurrent protection in electronic circuits. It is rated for a maximum voltage of 60V DC and a maximum current of 40A. The hold current is 1.35A, with a trip current of 2.7A. At 6.75A, the typical trip time is 9.6 seconds. The initial resistance ranges from 120mΩ to 190mΩ, with a one-hour resistance maximum of 300mΩ. Power dissipation in the tripped state is 1.7W.

 

The component is housed in a through-hole radial disc package with a diameter of 14.50mm, thickness of 3.10mm, and a seated height of 19.60mm. Lead spacing is 5.10mm, and lead diameter is 0.81mm. Terminal material is tin-plated copper. Operating temperature range is -40°C to 85°C. The device meets UL 94V-0 flammability requirements.

 

Note: This part is on phase-out and not recommended for new designs. Schurter recommends the PFRY.135 as a substitute. Typical applications include security and fire alarm systems, loudspeaker protection, and power transformer overcurrent protection.
