TVS (Transient Voltage Suppressor) diodes and metal oxide varistors (MOVs) are the two primary electrical components used in transient voltage suppression (TVS). Both devices are designed to absorb electrical voltage transients, providing protection for electrical components and systems. The MOV-14D241KTR is a metal oxide varistor (MOV) from Littlefuse that is designed to protect systems against electrical transients. This article will explore the applications and working principle of the MOV-14D241KTR.

MOV-14D241KTR is a unidirectional varistor similar to other metal oxide varistors used for transient voltage suppression. The MOV-14D241KTR has a maximum peak pulse current of 2.4 ka (8/20us) and is design correspondingly to the UL1449 3rd edition. MOV-14D241KTR device has a lower profile than many comparable varistors that have the same rating. The MOV-14D241KTR\'s compact design allows it to bypass large voltages and withstand pulse ratings up to 5ka (10/1000us).

The MOV-14D241KTR has a wide array of applications. This varistor is used in AC power lines, instrumentation, electronic control circuits, motor control circuits, switching power supplies, and telecommunications. It is also used in audio and visual equipment, industrial automation, battery operated circuits, automotive applications, and lighting systems. Its wide range of applications makes it very versatile.

The MOV-14D241KTR\'s working principle is based on a phenomenon known as the zinc oxide effect. The zinc oxide layer on the MOV-14D241KTR\'s surface is composed of grains that contain joule losses. When a voltage transient occurs, it causes a physical displacement of the zinc oxide layer and creates an electromechanical stress that causes the grains to deflect in a manner known as "bucking up." This bucking up process creates heat and dissipates the electrical current, providing protection for the system or component.

The MOV-14D241KTR is also designed to provide protection against surge noise. It can help reduce EMI and other RF-related interference. This type of MOV is designed to provide protection in a wide range of operating environments, including low-capacitance systems, power systems, and other applications that require transient voltage protection. Its low-capacitance characteristics make it ideal for sensitive applications such as automotive electronics.

In summary, the Littlefuse MOV-14D241KTR is a metal oxide varistor designed to provide protection from transient voltage transients. It is a unidirectional varistor with a maximum peak pulse current of 2.4 ka (8/20us). It has a wide range of applications, including AC power lines, instrumentation, electronic control circuits, motor control circuits, switching power supplies, telecommunications, and more. Its working principle is based on the zinc oxide effect, which creates an electromechanical stress that causes the grains to deflect to dissipate the electrical current. The MOV-14D241KTR is also designed to provide protection against surge noise and reduce EMI and other RF-related interference. Its low-capacitance characteristics make it ideal for sensitive applications such as automotive electronics.
