0071.1221.B1

The 0071.1221.B1 is a varistor, also known as a voltage sensitive resistance (VSR), used to protect sensitive electronic equipment from voltage spiking. When current passes through the device, it acts as a resistor, limiting the amount of power that can be passed to the protected device. Varistors are commonly used in applications such as AC line protection, circuit breaker protection, emi/rfi protection, and other power protection applications.

The 0071.1221.B1 is a metal-oxide varistor, a type of voltage-dependent resistor. Varistors are made up of two layers of metal oxides, sandwiched between two layers of porous materials. The porous layers provide a low-resistance path for the current, while the metal-oxide layers act as tiny resistors, providing a low resistance path when the voltage is low and a higher resistance path when the voltage is high. This allows the current to be limited when a large voltage spike occurs, protecting the connected device from the damage that a high voltage would otherwise cause.

The 0071.1221.B1 has a working voltage of 180 V, which means it can withstand up to 180 Volts of current before it starts conducting. Its maximum clamping voltage is 400 V, which means it will limit the voltage to 400 V or less before the current is allowed to pass. Its operating temperature range is -25°C to +100°C, meaning it can safely operate in a wide range of temperatures. It also has an insulation resistance of 1G Ohms, meaning it does not need to be grounded.

The 0071.1221.B1 is typically used to protect sensitive electronic equipment from power surges and voltage spiking. It can be used in a variety of applications, such as AC line protection, motor control, circuit breaker protection, EMI/RFI protection, and other power protection applications. It is also commonly used in automotive systems, industrial systems, communications systems, instrumentation systems, control systems, and more.

The 0071.1221.B1 is a reliable and safe device for protecting sensitive electronic equipment from voltage surges. It has an operating voltage of 180 V, a maximum clamping voltage of 400 V, an operating temperature range of -25°C to +100°C, and an insulation resistance of 1G Ohms. This makes it ideal for use in a variety of power protection applications, where precision and safety are essential.
