0458001.DR 0458002.DR 0458004.DR 0458005.DR 0458010.DR

on April 3, 2025

As electronic devices become increasingly sophisticated, current overload and short circuit are like latent “invisible killers”, threatening the safety and life of equipment at all times. The 0458 series fast-blow fuses (0458001.DR/0458002.DR/0458004.DR/0458005.DR/0458010.DR) are the “ultimate defenders” born to resist these threats. With nanosecond response speed and high reliability, they provide impeccable protection for all kinds of electronic equipment.

Product Features: Five swordsmen work together to cover all scenarios

0458001.DR	1A	48V/75V	50A	SMD1206	-55°C~+125°C	Low resistance (180mΩ), miniaturized design
0458002.DR	2A	48V/75V	50A	SMD1206	-55°C~+125°C	High cost performance, universal protection solution
0458004.DR	4A	32V/75V	50A	SMD1206	-55°C~+125°C	Wide voltage compatibility, industrial reliability
0458005.DR	5A	75V/75V	50A	SMD1206	-55°C~+125°C	High breaking capacity, harsh environment adaptation
0458010.DR	10A	63V/63V	50A	SMD1206	-55°C~+125°C	Ultra-high current protection, compact package

_{The entire system adopts a nano-scale melt structure, which combines low resistance characteristics (≤5mΩ) with nanosecond response speed, cutting off the current at the moment of short circuit to avoid device damage.}

Technical advantages: the art of fast, accurate and ruthless fusing

Lightning-fast response:
**** 0458005.DR has a fusing time of <20ms at 10 times the rated current, far exceeding the IEC standard requirements;
**** 0458010.DR adopts SMD1206 package, which is small in size but can withstand 50A interruption current and instantly cut off the fault circuit.
Precise fusing control
**** I²t characteristic optimization: The energy required for the fuse to fusing is accurately calculated to avoid false triggering or refusal to operate;
**** Wide temperature adaptability: The operating temperature range is -55℃~+125℃, and the stability is still excellent in extreme environments.
Low loss design: The resistance value is as low as 4.65mΩ (such as 0458010.DR), reducing circuit power loss and improving equipment efficiency.
