MOV-14D180KTR Circuit Protection

Transient voltage suppression (TVS) components are an important class of electrical circuit protection components, designed to limit and suppress transient high voltage transients. The MOV-14D180KTR belongs to the surge diverters, a sub-class of TVS components. The MOV-14D180KTR is a two-terminal nonlinear movable-contact device, commonly referred to as a metal oxide varistor (MOV).

Application Field
MOV-14D180KTR is commonly used to protect a wide range of electrical equipment and circuits from voltage transients and electrical surges. These transients can be caused by both internal and external sources, including lightning strikes, power disturbances, electrostatic discharge (ESD), or local inductive loads such as motors or solenoids. The MOV-14D180KTR can be used in a wide variety of applications, from automobiles, industrial equipment, consumer products, to computers and medical equipment. It can also be used in applications involving power lines, instrumentation equipment, and communication networks.

Working Principle
The basic function of the MOV-14D180KTR is to limit the peak voltage of an electrical surge or transient. It is designed to divert the surge current to ground, providing a low-impedance path to protect connected electronic devices. As the voltage across the device rises above its clamping voltage, the MOV-14D180KTR begins to conduct, shunting the current away from the protected circuit. The device has an internal clamping voltage of 180 VDC, a current rating of 14 A, and a peak pulse power dissipation of 1080 W.

The MOV-14D180KTR is designed with a relatively high resistance when the voltage is below the clamping voltage, which reduces the normal load current through the unit. When the voltage rises above the clamping voltage, the resistance decreases, allowing for enhanced current conduction and voltage suppression. The unit has excellent nonlinearity characteristics, providing fast and reliable overvoltage protection. The MOV-14D180KTR also features a low thermal impedance, which helps to reduce the energy dissipation in the device.

The MOV-14D180KTR is designed to provide reliable protection for a wide range of applications. With its high surge current rating, low clamping voltage, and low thermal impedance, the MOV-14D180KTR is well suited for use in a wide variety of electrical and electronic equipment, including medical equipment, industrial control systems, audio and video equipment, and computer systems. The device is also RoHS compliant, making it an ideal choice for applications requiring environmentally friendly components.
