PTF45 5x20mm PCB Mount Fuse Holder 10A 250VAC

PTF45 5x20mm PCB Mount Fuse Holder 10A 250VAC

The PTF45 is a 5x20mm PCB mount fuse holder designed for through-hole printed circuit board mounting. It accepts standard 5x20mm cylindrical fuses and is rated 10A at 250VAC.

This fuse holder uses PBT housing material rated UL 94 V0 for reliable flame retardant performance. It features a PC2 shocksafe protection category and IP20 degree of protection. Besides, its contact resistance stays below 5mΩ to ensure stable, low-loss electrical connection.

The PTF45 operates reliably across a wide ambient temperature range from -30°C to +85°C. Its standard colour is black, and other colours are available on request.

Derating Curve The PTF45 maintains full 2.5W power acceptance up to 50°C ambient temperature. Above 50°C, the allowable power acceptance decreases linearly. By 90°C, the derating reaches 0W, so continuous operation is not recommended.

Applications

• PCB mount power supply protection
• Consumer electronics and home appliances
• Industrial control boards
• LED lighting drivers
• Instrumentation and medical equipment

Ordering Information Standard colour is black. Other colours are available on request. For custom packaging or special lead forms, contact our sales team.
