What is the difference between patch fuse one-time and self-recovery

Patch fuses Disposable and self-restoring fuses are two different types of fuses used to protect electronic components in a circuit.

Disposable Fuse: Disposable fuse is a fuse protection device, when the current exceeds the rated current that the fuse can withstand, the fuse in the fuse will melt the break to prevent the current from excessive damage to other electronic components. Once the fuse melts, the fuse needs to be replaced to return to normal operation.

Resettable Fuse: A resettable fuse is also called a Positive Temperature Coefficient (PTC) fuse. It consists of a thermistor with a special conductive material. When the current exceeds the rated value, the fuse heats up, causing the resistance of the material to rise, resulting in a high resistance state that breaks the circuit. Once the excess current is gone, the fuse cools and returns to a low-resistance state, returning the circuit to normal operation. Therefore, the self-restoring fuse can be used multiple times without replacement.

Summary: The patch fuse is a fuse type fuse that needs to be replaced, while the self-restoring fuse is a protective device based on a thermistor that can be used multiple times. The choice of which fuse to use depends on the specific application requirements.

The maximum current capacity of the patch self-restoring fuse depends on the specific model and specification. In general, the rated current range of the patch self-restoring fuse can range from a few hundred mA to a maximum of 3A. 3A and above need to use disposable patch fuse

Choose between a disposable patch fuse or a self-restoring fuse

When choosing a patch self-restoring fuse for a specific application, the following points should be noted:

The rated current of the fuse is determined according to the rated current of the applied circuit. The rated current of the fuse should be greater than or equal to the rated current of the application circuit.

Consider the operating conditions of the application circuit, such as operating temperature, voltage, etc., to ensure that the selected fuse can work normally under these conditions.

The duration of the stream event is considered. Some self-restoring fuses can withstand high overcurrent for a short time, but will automatically change to a high resistance state after a certain time.

When purchasing a patch self-restoring fuse, you can view the technical parameter sheet of the product or consult the manufacturer to obtain the specific rated current value.
