Electrical, Specialty Fuses

LNRK6.25T limiters are designed to provide overcurrent protection for auxiliary circuits in electronic equipment. This product line provides reliable thermal and current protection capabilities with its fast-acting capabilities and it can be used in a wide variety of applications. The LNRK6.25T series features a unique design that allows it to provide high levels of overcurrent protection while still providing low off-state voltage drop.

Applications

The LNRK6.25T is suitable for a wide variety of applications, including consumer electronics, automotive, audio systems/amplifiers, instrumentation, telecommunications, telemetry, and power supplies. It is designed to protect circuits from damage due to overcurrents caused by the sudden switching of inductive or capacitive loads. The device’s fast reacting times of 10 microseconds or less helps dissipate excessive current quickly, further enhancing its safety functions. Furthermore, its ability to operate at temperatures up to 125°C makes it suitable for use in harsh environments.

Working Principle

The LNRK6.25T limiter operates on a bi-metal thermal activation principle. Upon the occurrence of an overcurrent event, the device responds by raising its temperature, causing the bimetallic element to flex and open the circuit, thus limiting the current. The device is able to reset itself, or can alternatively be reset manually. This helps in detection and mitigation of any further damages.

The LNRK6.25T features a unique coating that prevents oxidation of the contacts and ensures quick and reliable operation. This coating also wears off over time, so users must periodically check the status of the limiter to ensure optimal operation.

Conclusion

The LNRK6.25T offers an effective solution for overcurrent protection. It is designed with speed and safety in mind, allowing for reliable current protection in a variety of applications. The limiter’s unique design and coating also offer enhanced performance and longer lifespans.
