PTC Resettable fuses are used to protect electronics from overcurrent conditions. The MF-R160-AP is a resettable fuse designed for medical equipment and other applications where the risk of electrical shock needs to be minimized. It is a very small component, yet provides highly accurate current protection in a wide range of applications.

The MF-R160-AP is a combination of a TVS diode and a polymeric positive temperature coefficient (PPTC) device. The TVS diode provides transient and surge protection by limiting peak voltage across the terminals. The PPTC device functions as a thermal fuse which provides current limitation, and prevents damage to the connected device. The advantage of this combination of components is that the current limitation is both self-resetting and accurate.

When operating under normal conditions, the PPTC device does nothing. It only reacts when the current through it exceeds its rated current. Upon this occurrence, the device will heat up, and the temperature will continuously increase until it reaches its trip point. At this point, the device will open and break the circuit, thus limiting the current. When the current is reduced to below the rated current, the device will cool down, and the circuit will become operational again. The device can be reset multiple times until the maximum trip temperature is reached, after which it must be replaced. The benefit of resetting capability is that it prevents downtime in applications such as medical equipment.

The benefits of using the MF-R160-AP resettable fuse include space savings, as only one device can be used to provide both surge protection and current limiting. It also allows for more precise control over current limiting, resulting in fewer resets and more accurate protection. Furthermore, the device provides a low profile, which is ideal for space-constrained applications.

The MF-R160-AP is an ideal protection solution for medical equipment and other sensitive electronics. Its fast and accurate overcurrent protection, along with its resettable nature, make it an excellent choice for these applications. Its small size and low profile make it ideal for space-constrained designs, and its protection capabilities ensure the safety of the voltage sensitive components in the system.
