PTC Resettable Fuses are thermal-based over-current protection devices that prevent electric circuits from overheating and going into thermal runaway. The PTR016V0155-BK1 is a device among such PTC Resettable Fuses. The PTR016V0155-BK1 has the following features that make it uniquely suitable for a wide range of applications.

Applications Fields

This product is widely applied for notebook computers, LCD displays, automotive test boards, Lithium batteries, as well as other current-limiting and current protection applications.

It features excellent high operation temperature of 125°C, high dielectric strength of 2kVAC and a wide current range, from 5A to 1A, making it highly suitable for many types of electric products and high-power applications. Additionally, it has a small size and a generous surge capacity of 17A2S. Its overcurrent protection features include fast tripping time, current-limiting, and protection against short-circuits.

Principle of Working

The working principle of PTC Resettable Fuses and the PTR016V0155-BK1 is thermal-based. The core component of the PTR016V0155-BK1 is a bi-metallic element composed of two metals with different thermal expansion coefficients. When normal current flows through this element, the heat generated by such flow will cause one of the metals to expand greater than the other, resulting in a momentary displacement in the bi-metallic element. This will disrupt the circuit and thereby provide over-current protection.

When the current flowing through the circuit drops below the overcurrent threshold, the element deforms and the circuit is re-established. The element then cools down allowing forthe device to be reset, or re-used. The product also features high surge capacity, as well as fast tripping times, both key features in protecting electric circuits from damage due to overloads.

The PTR016V0155-BK1 is a highly versatile PTC Resettable Fuse that offers excellent protection through a wide range of applications. It features thermal-based protection, high surge capacity, over-current protection, and fast tripping times. It is suitable for a wide range of electric products and high-power applications, such as notebook computers, LCD displays, automotive test boards, Lithium batteries, and more.
