PTC Resettable Fuses

PTC (Positive Temperature Coefficient) Resettable Fuses, also known as polyfuses, are self-resetting temperature-sensing fuses. Characterized by their temperature-sensing elements, these fuses are designed to provide reliable short-circuit protection and current limiting. PTC resettable fuses are used in various electronic applications, such as AC/DC power supplies, automotive, telecommunications, domestic appliances, and medical electronics. In all these applications, the ability of a PTC resettable fuse to offer short-circuit protection is critical.

YPBL2.30T Application Field and Working Principle

YPBL2.30T is a small, temperature sensing PTC (positive temperature coefficient) type for over-current protection. This PTC resettable fuse is used to ensure a high level of safety, reliability and to protect against over-current or short-circuit conditions.The YPBL2.30T works on the principle of a thermistor. A thermistor is a temperature-sensing diode that has a negative temperature coefficient (NTC). When current is applied to the YPBL2.30T, the PTC is heated by the current passing through it. As the temperature of the PTC rises, its resistance also increases. This increasing resistance prevents further current from passing through it and causes the PTC to ‘trip’. When the over-current or short-circuit condition is relieved, the PTC will cool down and return to its low-resistance state, allowing current to flow again.The YPBL2.30T is suitable for use in a range of applications, including consumer electronics and automotive electrical systems. It has high current and voltage ratings, low leakage and high resistance to current shock, making it suitable for protection of consumer electronics and automotive components. The YPBL2.30T is also RoHS compliant, which means it is safe for use in a variety of electronic applications.

Advantages of YPBL2.30T

Compared to traditional thermal fuses, the YPBL2.30T has several advantages. Firstly, the YPBL2.30T is self-limiting and offers protection against short-circuit conditions. Secondly, it is temperature sensing and provides thermal protection against overload conditions and current surges. Thirdly, the YPBL2.30T offers superior current- and voltage-limiting performance. Lastly, it can be used in a wide range of applications and is RoHS compliant.

Disadvantages of YPBL2.30T

The main disadvantage of the YPBL2.30T is that it is a one-time use fuse. Once the over-current or short-circuit condition is relieved, the PTC must be replaced in order for it to regain its protection capabilities. This means that the YPBL2.30T is not suitable for use in applications where quick and reliable protection is necessary.

Conclusion

The YPBL2.30T is a temperature-sensing PTC resettable fuse that can be used for reliable short-circuit protection and current limiting in various applications. It offers superior current- and voltage-limiting performance, as well as high current and voltage ratings, low leakage and high resistance to current shock. However, due to its one-time use nature, the YPBL2.30T is not suitable for use in applications where quick and reliable protection is necessary.
