Intertechnik PTC Semiconductor – SE110

The Intertechnik PTC Semiconductor – SE110 is a reliable and cost-effective solution for safeguarding sensitive audio circuits against the damaging effects of overcurrent. As a positive temperature coefficient (PTC) device, it automatically limits current flow when a fault occurs, resetting once the condition is cleared, which makes it an ideal choice for both DIY enthusiasts and professional repair technicians seeking long-term protection without the need for fuse replacement. This component is particularly well-suited for use in loudspeaker crossovers, amplifier power supplies, and other electronic audio systems where consistent current regulation is essential to prevent component failure. The SE110 offers a holding current of 1.1 A and a maximum voltage of 60 V, ensuring robust performance in moderate-power applications. Its semiconductor construction provides fast response times and high reliability, while the compact design allows for easy integration into existing circuit layouts. With a low price point of 790 HUF, this PTC semiconductor delivers exceptional value for those looking to enhance the durability and safety of their audio equipment. Whether you are building a new project or upgrading an existing system, the Intertechnik SE110 is a practical choice for maintaining optimal performance and peace of mind.
