MR2520LRLX Application Field and Working Principle

The MR2520LRLX is a Metal-Oxide Varistor (MOV) designed for use in DC and AC applications. It is a nonlinear voltage regulator that can protect against power supply surges, spikes, and other forms of electrical noise. It is designed to provide protection to sensitive electronic components and systems from over-voltage transients.

The MR2520LRLX is suitable for a range of different applications. It is a preferred component for telecommunications, military specifications, medical electronics, and other applications that require superior surge protection. The device can also be used in voltage-sensing circuit design and other applications where noise suppression is desired.

The MR2520LRLX is composed of two segments. The first segment is a metal oxide layer, which provides the main surge protection. This layer consists of tin oxide (SnO2) and comprises a resistance of 5,000 ohms. The second segment is a thermally responsive layer, which is responsible for sensing over-voltage transients and providing a protective current path.

The working principle of the MR2520LRLX is based on the thermistor effect. When voltage exceeds its limit, the MOV will allow current to flow in the reverse direction, thereby limiting the voltage to a safe level. The thermistor layer increases its resistance in a nonlinear manner as the voltage increases, and reduces its resistance as the voltage decreases.

The MR2520LRLX also offers superior suppression characteristics, allowing it to quickly respond to a varying range of over-voltage transients. Moreover, this device features low power dissipation and offers a high thermal stability. In addition, it has a very low profile and is RoHS compliant.

The MR2520LRLX is a reliable, cost-effective, and easy-to-use DC and AC transient voltage surge suppressor. It provides excellent protection against sudden transient voltage spikes and can effectively protect sensitive electronic components and systems from damage caused by high voltage transients.
