This through-hole design is suitable for panel or PCB mounting where space allows and where quick protection is essential in telecom or consumer electronics circuits.
Heyiarbeit Pico Fuse 125V 3A (50Pcs)
Brand: Heyiarbeit. Technical parameters include a fuse rating of 125V and 3A, with a fast-blow mechanism and axial lead construction. The green resistance-type fuse is designed to blow quickly under high current load to protect equipment, making it suitable for telecom and communications gear. The axial lead form accommodates easier retrofits and through-hole PCB assembly, while the fast action is aimed at minimizing damage to sensitive circuits during faults.
uxcell 250V 3A Fast Blow (20pcs)
Brand: uxcell. This product lists a higher voltage rating of 250V with a 3A current rating and a quick-breaking fuse type. The fuse size is specified as 8x3mm (0.3″ x 0.1″), suitable for compact boards where precise axial leads and limited space are considerations. Users should ensure the circuit is designed for 250V or higher supply and that professional knowledge is applied when replacing fuses in telecom or power electronics to avoid misapplication.
Fielect Pico Fuse 250V 3A (20pcs)
Brand: Fielect. Specifications include 250V rating and 3A current, with no self-recovery. The fuse is composed of high-precision metal designed for durability, and its fast-blow behavior helps protect critical electronics from faults by interrupting current quickly. It is suitable for telecom gear and other applications requiring robust protection at higher voltages, with through-hole mounting options for easy circuit integration.
Fielect Pico Fuse 250V 3A (50pcs)
Brand: Fielect. Rated at 250V and 3A, with no self-recovery. The fast-blow fuse construction uses metal elements designed for long-term reliability. In telecom or high-current electronics, this fuse provides swift disconnect under fault conditions to safeguard devices and important components from damage, ensuring safer circuit operation in higher-voltage environments.
Bettomshin Pico Fuse 125V 3A (50Pcs)
Brand: Bettomshin. Specifications include 125V rating and 3A current with a fast-blow function and no self-recovery. The fuse features a high-precision metal composition designed for durability and long service life. It is suited for telecom and other electronics that require fast protection against arcing or short circuits, helping prevent damage to sensitive components and maintaining circuit integrity.
Buying Guide: Key Considerations for 3A Pico Fuses
- Voltage rating: Choose a rating that matches or exceeds your system voltage. Higher voltage fuses (e.g., 250V) are not always interchangeable with lower-voltage circuits.
- Current rating: A 3A fuse is intended to protect circuits drawing current near or below 3A. If your load can spike above this, consider a higher rating or a fuse with appropriate headroom.
- Fast-blow vs slow-blow: Fast-blow fuses interrupt quickly and are suitable for circuits with stable inrush; slow-blow fuses tolerate surges. Ensure the fuse type matches your application’s inrush characteristics.
- Lead type and mounting: Through-hole and axial-lead formats are common for hobbyist boards and telecom gear. Confirm the physical size (e.g., 8x3mm) fits your enclosure or PCB.
- Durability and material: Look for high-precision metal construction and long-term reliability, especially in harsh environments or field deployments.
- Replacement and documentation: Keep track of part numbers and manufacturer guidelines to ensure correct replacement and safe operation.
- Applications: Telecom, networking gear, and consumer electronics often require fast-protection fuses to guard critical components from transient faults.
The selections above reflect a range of voltage ratings and lead styles, offering options for both low- and high-voltage circuits. When integrating these fuses, ensure compatibility with your device’s electrical specifications and follow safety guidelines for handling and replacement.
