PTC Resettable Fuses, such as YQD100N0150, are widely used in over-current protection applications. They are designed to limit the current passing through the circuit, protecting the circuit from immediate destruction due to short circuit or overload condition. YQD100N0150 has been extensively used in a wide range of applications, mainly for protecting electronic devices, components, and sub-systems from electrical pulses.

YQD100N0150 is composed of a polymeric material that acts as a thermal resistor element, which can adjust its resistance depending on the temperature. The current passing through YQD100N0150 would cause the resistor element to heat up. When the temperature rises to a certain threshold, the resistor element will rapidly change its resistance, suppressing the current. When the overload situation is over, the resistor element would cool down slowly. When the temperature returned to room temperature, the resistor element’s resistance would reset to its original state, thus the name resettable fuses.

YQD100N0150 is incredibly fast in acting, and would take less than 2 milliseconds to open after detecting the overload or short circuit condition. On the other hand, the time it requires to reset its resistance is usually longer, takes from several seconds to couple of minutes, making it perfect for applications that require real-time protection with fast response. YQD100N0150 is also designed with high margin of safety, in order to ensure that the circuit and components would not be damaged in the event of repeatedly overloads.

YQD100N0150 can be further divided into two types according to their size, surface mount and through hole types. The surface mount type is the most popular one, due to its simply mounting and convenient implementation. It doesn’t require extra space, and easy to be soldered with other components in the circuit.  The through hole type is ideal for those projects that require bigger installation space and more current Maximum Operating Temperature (MOT). It also enables easy clearance of high current fuse applications.

YQD100N0150 can be used to protect almost any type of equipment with an electric power. The applications are diverse, ranging from medical instrument, industrial appliance, consumer electronics, automobiles and many more. Its stable and consistent performance, as well as its compact size and fairly high endurance limit, make it well suited for a wide variety of applications.
