RJS 1.5

Specialty Fuses – RJS 1.5 Application Field and Working Principle

RJS series of fuses are miniature radial leaded slow-acting current-limiting fuses, suitable for miniature electronic equipment, power supplies, LED module lighting, battery packs, and other electronic devices. The RJS series are rated for up to 1.5A and are available in ceramic or plastic versions for various applications.

RJS 1.5 Application Field

Typical applications for RJS 1.5 fuses include: additional circuit protection for power sources that are operated at high current levels; protection for sensitive and/or critical circuit components; fuse-links in battery packs and portable electronic devices; power surge and over-voltage protection; and applications where a reliable, low-resistance, circuit protection solution is required.

RJS 1.5 Working Principle

RJS 1.5 fuses are designed with a built-in metal element that melts open when a fault current is detected. This element is connected in series with the protected line and, when the current drawn by the protected circuit exceeds the rated value of the fuse, the element melts open, breaking the circuit and preventing further current flow. This mechanism of operation provides both reliability and a low impedance solution for over-current protection.

The RJS 1.5 fuse is designed with a ceramic body and is available in both cermet and plastic versions. The fuse body is rated for up to 350 VAC and provides over-voltage and surge protection up to 1 kV. Additionally, the fuse is designed with a low-resistance element, making it suitable for high-current applications.

Conclusion

In summary, the RJS 1.5 fuse provides reliable circuit protection in high-current applications, with low resistance and surge and over-voltage protection. The fuse is available in both ceramic and plastic versions, allowing it to be used in a wide variety of applications.
