Miniature cylindrical fuse 5X20 HF 2A/250V 006710208

Miniature fuse links – protection of precise circuits

The 5x20 mm HF 2A/250V fuse link is a protective element designed to protect delicate electronics and circuits requiring a fast response to overvoltages. It is a key component in ensuring the reliability and safety of devices. Its compact dimensions make it ideal for use in miniaturized electronics, where every millimeter counts.

Characteristics and application

The fuse link is characterized by HF (High Fast) characteristics, which means a very fast response time to overvoltages. This is important in protecting electronic circuits sensitive to short-term voltage spikes, such as those occurring during operation with motors or inductive loads. The short-circuit breaking capacity of 1.5kA and the high Joule integral value (4.2 A²s) demonstrate its effectiveness in interrupting the circuit in the event of a failure.

This fuse link finds wide application in:

• Protection of switch-mode power supplies
• Control circuits
• Measuring electronics
• Audio-video equipment
• Generally – everywhere where fast and reliable protection against overloads and short circuits is required.

Construction and parameters

The fuse link has a ceramic body, which provides good electrical insulation and resistance to high temperatures. Its dimensions (5x20 mm) are a standard in the industry, making replacement and installation easier. The rated current of 2A and the rated voltage of 250V AC/DC make it suitable for a wide range of applications. Power losses at 1W minimize the impact on the energy efficiency of the protected circuit. It meets the standards IEC 60127-1 and IEC 60127-2, which guarantees its compliance with international safety standards.

Thanks to its construction and parameters, this fuse link is a reliable solution for installers and users looking for effective protection for their electronic devices. The fast response to overvoltages minimizes the risk of damage, and the solid construction ensures long-lasting and trouble-free operation.
