BEL FUSE
Fuses, PPTC protection devices and circuit protection components
About the manufacturer
Bel Fuse Inc. is a US-based electronic component manufacturer developing solutions for circuit protection, power conversion, signal transmission and connectivity. Founded in 1949, the company has expanded its portfolio for industrial electronics, telecommunications, data centres, automotive, transportation and consumer equipment.
Circuit protection is one of Bel’s key technology areas. Its portfolio includes through-hole and surface-mount fuses, miniature fuses and resettable polymer PTC devices. These components help limit the effects of overloads and short circuits while keeping the protection solution compact.
Bel also develops magnetic components, power solutions and interconnect products. This gives the company a strong position in projects where circuit protection must work together with reliable data transmission, stable power delivery and long service life.
The manufacturer serves both large OEMs and electronics designers looking for components suitable for series production and compliance with international requirements.
Applications
Bel Fuse components are used wherever reliable circuit protection is required to reduce the effects of overloads, short circuits and temporary fault conditions.
- Power supplies and converters – protection of input and output power paths.
- Industrial electronics – protection of controllers, I/O modules and automation systems.
- Telecommunications and networking – protection of routers, switches and transmission equipment.
- Consumer electronics – protection of main boards and power modules.
- Battery systems – protection of battery packs and charging circuits.
- Automotive and transportation – protection of auxiliary circuits and power systems.
- Data centres and IT infrastructure – protection of equipment designed for continuous operation.
BEL FUSE products available from Maritex
The Bel Fuse range available from Maritex focuses primarily on circuit-protection components, including resettable polymer PPTC fuses for electronics, power systems and battery applications.
Available product groups include:
- Resettable PPTC fuses in SMD packages.
- Polymer PTC protection devices for low-voltage circuits.
- Components from the 0ZCF, 0ZCG and 0ZCJ families.
- Variants with different hold and trip currents.
- Protection components for electronic devices and power systems.
Available examples include 0ZCF0075AF2C, 0ZCG0110AF2C and 0ZCJ0075AF2E. Individual versions differ in package size, current rating, operating voltage and post-trip resistance. Selection should take into account normal circuit current, ambient temperature, rated voltage and the required protection response.
