Introduction

PTC Resettable Fuses, also known as Polyfuse or Positive Temperature Coefficient (PTC) Devices, are complex electronic components that can be used to protect electronic circuits from overcurrents. PTC Resettable Fuses are an excellent alternative to traditional fuse systems, as they offer enhanced protection, improve current availability, and reduce cost and maintenance requirements.The PTC Resettable Fuses product range from traditional fused power protection to small, low power current protection. The PTR016V1100-BK is a relatively small device, measuring 17.5mm x 8.0mm x 4.5mm, and is designed to provide overcurrent protection in industrial, automotive, and consumer electronics applications.

Application Field

The PTR016V1100-BK is a high performance device designed to provide overcurrent protection in a wide variety of applications. It is used in applications such as industrial, automotive, and consumer electronics where over-current and short circuit protection is required. In industrial applications, it is used for motor control, process control, and power conditioning systems. The device can be used in a variety of automotive applications such as airbag deployment systems, electronic ignition control systems, and vehicle lighting systems. It is also used in application such as cellular phones, PDAs, computers, and other consumer electronics where current limitation and temperature sensing protection is required.

Working Principle

The working principle behind the PTR016V1100-BK is quite simple. When the current passing through the device exceeds its rated current, a PTC thermistor is activated, tripping the device and opening the circuit. In operation, the device provides fast and reliable over-current protection. The device will automatically reset itself once the over-current condition has been removed.The device features a high melting point which ensures that it will be able to provide consistent protection in all environments. The device also has a high insulation resistance of 10,000 megohms that prevents electrical breakdown from the high power surges that can occur in industrial, automotive, and consumer electronics applications.The device construction consists of two electrodes and a bridge diode. The two electrodes are designed to sink current when the device is activated, and the bridge diode is designed to conduct away any excess current that is generated during the activation process. This device also features a current-sensing voltage that is used to protect the circuit from high voltage and current surges.

Conclusion

The PTR016V1100-BK is a versatile and reliable device designed to provide fast and effective overcurrent protection for industrial, automotive, and consumer electronics applications. The device is constructed with high-quality components, provides fast response time, and can easily be reset after an over-current condition has occurred. This makes it an ideal choice for any application that requires reliable current protection.
