Vishay Intertechnology, Inc. PTC Resettable Fuses PTCTT95R500GTE

The 1015226-PTCTT95R500GTE is a PTC resettable fuse designed for circuit protection in telecommunications applications. It features a resistance value of 50 Ohms at 25 °C and operates within a temperature range of -40 °C to 85 °C. The device can handle a maximum voltage of 240V RMS and an overload current ranging from 2.5A to 8.0A. The maximum trip time at 1A is between 1.2 to 4.0 seconds, making it suitable for quick response to over-temperature and overload conditions. This component is constructed with two high-performance PTC ceramics mounted on an alumina spacer, featuring lead-free tin-plated contacts. It is designed for surface mount technology (SMT) with a small footprint, allowing for efficient PCB space utilization. The fuse is compliant with ITU standards and is suitable for both lead-bearing and lead-free soldering processes. The product is packaged in tape and reel format, facilitating automated assembly. Engineers considering this component should note its specifications for effective integration into their designs, particularly in telecommunications infrastructure, PABX systems, and set-top boxes.
