PTF-50 PCB Mount 5x20mm Fuse Holder (10A 250V, Black PBT)
The PTF-50 PCB mount fuse holder is a printed-circuit-board mounted 5x20mm fuse holder with a knurled screw cap for fast fuse replacement. Its black PBT body meets UL94V0 flame rating, rated 6.3A / 10A at 250V or 125V (AC/DC), with 50A breaking current and 3000VAC dielectric withstand. The 0.4mm phosphor bronze pins solder directly onto the PCB, making it ideal for power supplies, adapters and industrial control equipment.
Key Features
- PCB Mount with Screw Cap — Through-hole pins (Ø1.3mm) solder to PCB; knurled cap opens without tools for quick fuse change.
- Accepts 5x20mm Fuses — Fits standard 5 x 20mm glass / ceramic cartridge fuses.
- 6.3A / 10A, 250V (125V) AC/DC — 2.5W (6.3A) / 1.6W (10A) power acceptance.
- Black PBT UL94V0 Body — Heat-resistant, self-extinguishing, matte black finish.
- 50A Breaking Current — Reliable circuit interruption; 3000VAC withstand voltage.
- Phosphor Bronze Pins — 0.4mm, contact resistance <5mΩ, insulation resistance >100MΩ.

FAQ
What fuse size does the PTF-50 accept?
It accepts standard 5 x 20mm glass or ceramic cartridge fuses.
Is it a PCB mount or panel mount fuse holder?
It is a PCB mount holder. The Ø1.3mm pins are soldered directly onto the circuit board, while the knurled screw cap allows fuse replacement without desoldering.
What is the maximum current and voltage?
6.3A or 10A at 250V / 125V AC or DC, with 50A breaking current.
Is the housing flame retardant?
Yes. The black PBT body meets UL94V0 flame-retardant grade.
Can I get samples or OEM packaging?
Yes, free samples are available. Packaging: 500pcs/bag or 2000pcs/box. Contact us for OEM/ODM.
