PTC resettable fuses have become popular in electronic applications, mainly because of their ability to detect potential overcurrent conditions and protect the device they are protecting from damage. PTR016V1100-TR is an example of such devices, and here we discuss its application field and working principle.

What is PTR016V1100-TR?

The PTR016V1100-TR is a type of polymer positive temperature coefficient (PPTC) resistor used in electronic devices for overcurrent protection. It is a component of a larger family of resettable fuses called PolySwitch Devices, which are designed to protect electronic devices against damage from excessive currents for up to 1500 V ac or dc.

Application Field and Working Principle

PTR016V1100-TR is a component used in a wide variety of applications such as mobile phones, servers, industrial devices, and white goods, among others. It offers protection for the following components:

• Overcurrent circuits.
• Overvoltage circuits.
• DC circuits.
• AC circuits.

The working principle of the PTR016V1100-TR is based on the PPTC material and its ability to sense an overcurrent condition. When the current exceeds the hold current rating, the PPTC material heats up, reaching a threshold temperature that activates the device. This changes the resistance of the device from a low resistance to a higher resistance. This will cause the current draw of the protected device to be reduced significantly and the device will be safe from possible damage.

When the current is reduced under the resumption current value, the device will slowly return to its normal low resistance state. This allows the current to pass through the PTR016V1100-TR again, and it is then ready for reuse. The device can be reset multiple times without any reduction in performance.

Advantages

The main advantages of using the PTR016V1100-TR as an overcurrent protection device are:

• Easy to install and use.
• It has a wide operating temperature range, making it suitable for a variety of applications.
• It can be reset multiple times without having to be replaced.
• It has low power loss and a low resistance when properly aligned.
• It has a high hold current rating to provide superior protection.

Conclusion

The PTR016V1100-TR is a resettable fuse designed specifically to provide overcurrent protection for electronic devices. It offers the advantages of a wide range of operating temperatures, low power loss, and reset ability, making it ideal for use in a variety of applications. With its combination of reliable overcurrent protection and reset capability, the PTR016V1100-TR is an ideal solution for electronic device protection.
