Cylindrical glass miniature fuse 5X20 F 400 MA/250V 006710015

Compact protection for electronic circuits

This miniature cylindrical fuse link with dimensions 5×20 mm provides reliable protection for delicate electronic circuits against overload and short circuits. Thanks to its fast-acting (F) characteristic, it reacts immediately to any current exceeding the permissible limit, protecting sensitive components from damage.

Operating parameters and characteristics

The fuse operates at a rated current of 400 mA and a voltage of 250V, making it ideal for use in low-power electronic devices. The glass body with an optical trip indicator allows for quick identification of a blown fuse.

The fast-acting characteristic ensures the element reacts instantaneously to short circuits and significant current overloads, though it may be more sensitive to short-term current surges during device startup.

Construction and materials

The product belongs to the Ultra-Quick series from ETI POLAM, which guarantees high manufacturing quality and consistent parameters. The glass body provides not only aesthetics but, above all, enables optical inspection of the component's status without the need for disassembly.

The compact 5×20 mm dimensions allow for installation in standard cylindrical fuse holders, occupying minimal space in electronic devices.

Application and compatibility

The component finds wide application in consumer electronics, audio-video equipment, measuring devices, and IoT applications. It is effective as protection for low-voltage power circuits, control systems, and delicate electronics.

Due to its standard dimensions, it is compatible with most 5×20 mm fuse holders and bases available on the market.
