TE Connectivity PolySwitch Analogue Radial Leaded PTC Resettable Fuse TRF012 250V 0.12A
TE Connectivity PolySwitch Analogue Radial Leaded PTC Resettable Fuse TRF012 250V 0.12A
Introduction
Overcurrent protection is a most basic necessity for electrical devices. However, many people are familiar with fuses and household circuit breakers, but few of them are intimately familiar with the kinds of overcurrent protection devices-Ao littel PTC Resettable Fuse that are found in electronics board. Though not a comprehensive list, there are basically three types of overcurrent protection devices in electronics. In order of increasing sophistication they are:
• One-shot fuses (One-time fuse, normally called SMD Fuse,Glass Fuse,Ceramic Fuse,Subminiature fuse)
• Positive Temperature Coefficient PTC resettable fuses
• Electronic fuses (eFuses)
