Key Features
- Radial through-hole mounting for secure PCB installation in high-vibration environments
- RoHS-compliant and REACH-compliant construction for global market access
- 24.1 mm x 3 mm compact radial body fits standard PCB fuse holder footprints
- Bulk packaging option suitable for high-volume production assembly
- Designed for reliable overcurrent protection in industrial and consumer electronics
Applications
The 30R900UH fuse is used as an overcurrent protection element in power supply boards, motor control circuits, and industrial control panels where through-hole mounting provides greater mechanical robustness than SMD alternatives. Its radial lead configuration allows direct PCB insertion with standard automated insertion equipment, reducing assembly costs for high-volume production. The component is also suited for replacement in existing designs that specify radial fuse form factors for legacy compliance.

Frequently Asked Questions
What are the physical dimensions of the 30R900UH fuse and how does it mount on a PCB?
The 30R900UH has a radial body measuring 24.1 mm in length and 3 mm in width, with a package height of 31.6 mm including leads. It uses through-hole radial mounting, inserted directly into PCB holes and soldered from the underside, providing a secure mechanical connection suitable for high-vibration industrial environments and power supply boards.
Is the 30R900UH fuse compliant with RoHS and REACH environmental regulations?
Yes, the 30R900UH carries both RoHS and REACH compliance codes, confirming it is manufactured without restricted hazardous substances such as lead, mercury, and cadmium. This makes it eligible for use in consumer electronics sold in the EU and other markets with strict environmental directives, and it meets the JESD-609 e3 moisture sensitivity classification for standard handling.
In which circuit protection applications is the 30R900UH radial fuse typically deployed?
The 30R900UH is commonly deployed as an overcurrent protection fuse in AC and DC power supply boards, motor drive circuits, and industrial automation panels. Its through-hole radial form factor provides mechanical stability under vibration and thermal cycling found in factory equipment. It also suits legacy equipment repairs where radial fuse holders with 3 mm body width are already installed, avoiding the need for PCB redesign.
