The ERZ-E 08F271 is one of the most popular varistors, MOVs (metal oxide varistors) used by engineers and electrical professionals around the world. These devices are designed to control voltage transients, also known as surge pulses, in order to protect power distribution systems, automotive or industrial electronics, and communication equipment. The ERZ-E 08F271 safely absorbs highly dynamic and unpredictable voltage spikes so that downstream components are not damaged.

The ERZ-E 08F271 is a single-component, PTC-based, non-linear voltage-dependent protection device. It has a wide range of operating voltages, allowing it to be used with all kinds of AC and DC systems. It\'s designed to handle pulses up to 8,000A (8kA) peak impulse current. The device has an operating temperature range of -40 °C to +90 °C (-40 °F to +194 °F). It is UL1449 recognized and CE marked.

The working principle of the ERZ-E 08F271 is based on non-linear resistance which is created by an increase in temperature due to Joule heating. When the voltage across the device is below its blocking voltage, called the clamping voltage, the device will have a high resistance and will be incapable of passing any current. When the voltage rises above its clamping voltage, it quickly changes to a low resistance, allowing it to absorb the surge current. The absorbed current will cause the device to heat up, causing the resistance to increase again, and limiting the current until the voltage rises back below the clamping voltage.

The ERZ-E 08F271 can be used in a wide variety of applications, including AC and DC power distribution, telecom-grade equipment, automotive electronics, heavy-duty machinery, instrumentation, medical electronics, home appliances, office equipment, and more. It is particularly well suited for installations where a low clamping voltage is required. It is also a good fit for installations with a high amount of noise or with low impedance power supplies because it can absorb high surge currents without compromising other components.

Overall, the ERZ-E 08F271 is a dependable and versatile non-linear voltage-dependent protection device that can reliably protect against surge Voltages and impulses. Its wide range of operating voltages and high peak impulse current capabilities make it an excellent choice for any application.
