PTC Resettable Fuses, also known as polymeric positive temperature coefficient (PPTC) or multi-layer positive temperature coefficient (MPTC), are designed to replace slow-blow fuses in power supply applications. RLD30P160UF is one of such models, it has a maximum voltage rating of 160VDC and a maximum current rating of 30A. Its physical size includes a 0.25” diameter, 0.5” length, and a maximum load of 0.2”.

Disc type PTCs, such as the RLD30P160UF, are made with two layers of polymeric material which are joined at edges or, in some cases, annealed to create a single, integral unit. The two layers of material form a junction, forming a temperature sensitive switch. The resistance of the junction is low when it is cool but increases as the temperature of the junction rises. This is known as the positive temperature coefficient (PTC) characteristic. The current limit of the PTC is affected by its temperature, and the higher the temperature, the higher the current limit.

In a manner similar to other types of fuses, the RLD30P160UF is designed to protect against overcurrents caused by short circuits or other system faults. It does so by limiting the amount of current that can flow through it when it reaches a predetermined temperature, meaning the device must be heated to a point where the internal junction can resist current flow. The temperature that triggers this overcurrent protection can be pre-set by the user, making the RLD30P160UF an ideal device for protecting power supply applications.

An important feature of the RLD30P160UF is its ability to reset itself after the overcurrent has been cleared. This eliminates the need for replacing the device, which makes it ideal for use in applications where power outages are frequent and the device needs to be reset quickly. When the overcurrent is cleared, the PTC cools down and its resistance returns to its original level, allowing current to flow again.

In addition to its re-settable feature, the RLD30P160UF also offers a number of benefits when compared to traditional overcurrent protection devices. Most notably, it is extremely small, making it ideal for use in applications where space is limited. Additionally, the device\'s relatively low temperature rating makes it appropriate for a wide range of power supplies and applications. Finally, the RLD30P160UF is much more cost-effective than traditional overcurrent protection devices, making it an attractive option for those seeking cost-savings.

Overall, the RLD30P160UF is an interesting addition to the world of power supply protection. With its re-settable feature, small size, low temperature rating, and cost effectiveness, it offers a unique combination of features that are sure to make it an attractive option for designers and engineers looking for a reliable and cost-effective way to protect their applications.
