BETTER ELECTRONICS

Miniature fuses and circuit-protection components

About the manufacturer

BETTER ELECTRONICS is a brand of Dongguan Better Electronics Technology specialising in circuit-protection components for electrical and electronic equipment. Its products are designed to protect devices against overloads and short circuits, while compact dimensions allow direct PCB mounting.

The manufacturer’s range includes miniature fuses with different time-current characteristics, rated voltages and mounting methods. Sub-miniature through-hole fuses are especially useful where designers need to replace larger cartridge fuses in space-constrained equipment.

These devices are important in safe mains-powered and locally converted power architectures. A properly selected fuse helps limit fault energy and protects transformers, power supplies, wiring and other electronic components.

The products are aimed at series-produced consumer and industrial electronics where repeatable trip behaviour and compact construction are important.

Applications

BETTER ELECTRONICS fuses are suitable for equipment that requires simple and effective overcurrent protection without consuming significant PCB area.

• Mains and switching power supplies – input and output protection.
• Consumer electronics – TVs, audio equipment, appliances and accessories.
• Industrial automation – protection of control and actuator modules.
• Measurement equipment – protection of supply rails and power inputs.
• LED systems – protection of power supplies and lighting drivers.
• Office and telecom equipment – protection of power modules.

BETTER ELECTRONICS products available from Maritex

The BETTER ELECTRONICS range available from Maritex includes miniature through-hole fuses designed for protecting electronic and power circuits.

Available product groups include:

• Sub-miniature THT fuses.
• Time-lag fuses for PCB mounting.
• Protection devices rated up to 250 VAC.
• Compact fuses for mains-powered equipment.

One example is F212-S-1A, manufacturer code 2121100204A – a 1 A / 250 VAC time-lag THT fuse in a compact 7.8 x 3.5mm package. Selection should consider rated current, inrush current, time-current characteristic and interrupting capacity.
