B72210S0251K531

B72210S0251K531 is a Varistor, also known as a voltage-dependent resistor (VDR), that has a non-linear current-voltage characteristics. It is a passive component that can provide surge protection for a wide range of power-based systems. The product is part of a larger family of pulse-resistant circuit protection solutions produced by EPCOS, a leading supplier of such solutions. The device enables systems to withstand surges in voltage and current that can cause damage or disruption.

The B72210S0251K531 Varistor has highly effective protection against voltage and current surges due to over-voltage, over-current, lightning, electrostatic discharge and more. The device has a non-linear voltage-current characteristic, which means that it can absorb or divert large amounts of energy while still conforming to the current standards. This helps ensure the protection of sensitive electronics, motors and other systems.

The device is widely used in a variety of electronic applications, including consumer electronic devices, PCs, automotive systems, power components, communications equipment, LED lighting, medical equipment and more. It is typically used for secondary protection, meaning that it is installed in parallel to the main circuit, so that it can absorb or divert energy before it can cause damage to the main circuit. It can also be used to protect against short-circuit and over-voltage/over-current events. Additionally, the Varistor’s surge protection ability can be extended by connecting additional varistors in series.

The B72210S0251K531 Varistor features a variety of characteristics, including a rated surge current of 100 A (8/20 μs waveform), a withstanding surge current of 9 A (8/20 μs waveform) and an energy dissipation of 2 J (8/20 μs waveform). It also has a rated voltage of 250 VAC and a maximum rated operating temperature of +85°C. It is available in both radial and axial lead forms, in a size of 4 × 4mm.

The B72210S0251K531 Varistor is designed to protect against surges caused by transient over-voltage and over-current. It features a low-capacitance design, providing excellent high frequency performance. Furthermore, the device is designed to provide very low residual voltage. This ensures that the circuit will not be damaged or disrupted by residual voltage left behind by the device even after heavy surge events.

In conclusion, the B72210S0251K531 Varistor is a highly effective device for providing surge protection in a variety of electronic applications. It features a non-linear voltage-current characteristic, enabling it to absorb or divert large amounts of energy before it can cause damage to the main circuit. Additionally, its low-capacitance design helps to ensure high-frequency performance, and its low-residual voltage feature helps to ensure that the circuit will not be damaged or disrupted. With all these features, the device is an excellent choice for a wide range of power-based systems.
