PTC resettable fuses are a type of fuse that can be reset after an overcurrent has caused them to trip. This type of fuse is used in many consumer, industrial and medical applications. 0ZRM0017FF2C is an example of such a resettable fuse. The 0ZRM0017FF2C is a Polymer Positive Temperature Coefficient (PPTC) fuse that offers solid-state overcurrent protection with a response time of just 2.5 microseconds. It is available in a single-pole, single-throw (SPST) package.

The main functional features of the 0ZRM0017FF2C PTC resettable fuse include:

• Low trip current down to 0.075 Ampere
• High hold current up to 0.5 Ampere
• Low temperature coefficient of -80 ppm/C
• High interrupting capacity up to 40 Amperes
• High breaking capacity up to 4 Amperes, compared to traditional ceramic fuses
• High temperature range of -40°C to +85°C
• High voltage rating of 250 Volts AC.

The 0ZRM0017FF2C is an ideal choice for use in medium-current applications that require a slow-acting fuse. Its wide operating temperature range and high voltage rating make it suitable for use in a variety of applications. Examples include medical equipment, instrumentation, communication systems, consumer electronics, and portable equipment.

The working of the 0ZRM0017FF2C is based on the thermistor principle. The device is made of a semi-conductive material with a high sensitive resistive element. It is designed to provide a safe and reliable overcurrent protection in normal operation. When the current exceeds the rated current, the device will conduct and the temperature rises quickly. This causes the conductive material to expand, which results in the device switching to an open state. This opens the circuit and interrupts the current flow.

Once the device has tripped, the resetting process involves cooling the device to a temperature well below the trip point, allowing the material to contract and re-establish its original performance characteristics. This process of resetting the device can be done manually, or it can be automatic depending on the application.

The 0ZRM0017FF2C is a robust and reliable PTC resettable fuse. Its small size, fast response time and high current load capacity combine to make it an ideal choice for a number of applications. Its use in medium-current applications is particularly well suited due to its current ratings and temperature compensation features. Furthermore, its resetting process and automatic resetting capabilities make it a very attractive choice for many applications.
