The V140LU10CPX2855 is a high performance rad-hard varistor specifically designed for spacecraft applications. It is a radial leaded disc-shaped varistor with an identical diameter and thicker construction compared to its previous versions. It is available with an operating voltage range of up to 2,200 volts. Designed to meet the requirements of EEE-HC-525 / MIL-STD-883, this varistor offers reliable protection against high voltage and electrical surges.

Varistors are used to protect sensitive circuits from damaging or disruptive electric transients and surges that can be caused by lightning or switching operations in power and data lines. These devices are designed to act as a shunt that, when a voltage transient passes, quickly diverts the current to the ground to reduce the voltage level and protect the controlled device.

Varistor technology, also referred to as “voltage-dependent resistors” (VDRs), is a special type of semiconductor device. It consists of a metal oxide semiconductor (MOS) element that is sandwiched between two external metal plates to form a parallel plate configuration. A voltage is applied across the resistance element. As the voltage across the device increases, the resistance of the device decreases, allowing higher current to flow and diverting the current around or away from sensitive circuits.

The V140LU10CPX2855 is an ideal choice for aerospace and space applications, as it can handle a wide range of voltages and is radiation hardened. It is also suitable for any application that involves sensitive power or data lines.

The varistor works by sensing high voltage and current surges and quickly diverting the current away from controlling devices. When a high voltage surge occurs, current is allowed to pass through the varistor and quickly shunted away from the controlling device. This helps protect the component from over-voltage surges.

The V140LU10CPX2855 is a highly reliable varistor that is designed to survive through rigorous environmental testing, provide reliable operation, and protect circuits from over-voltage. It is also robust enough to withstand the rigors of spaceflight and provides simple, low cost protection for mission critical applications.

In conclusion, the V140LU10CPX2855 is an advanced radial leaded, shielding varistor specifically designed for spacecraft applications. It is designed to provide reliable protection against voltage and current surges, and to act as a shunt that diverts current around or away from sensitive circuits. This varistor is ideal for aerospace and space applications, as it can operate under wide voltage ranges and is radiation hardened.
