The V321CA40PS is a Varistor/Metal Oxide Varistor (MOV) used to protect sensitive electronic equipment from transient voltage surges. This type of Varistor can be used to protect both parallel and series connections of circuits. They are designed to have a high surge current handling capability, providing reliable protection against transient over-voltages.The V321CA40PS has a very low leakage current rating which helps to maintain a low internal temperature of the device. It also features a maximum clamping voltage rating, which acts to limit the peak voltage across the device to a specific level during a surge event. This ensures that the V321CA40PS is able to provide effective surge protection to the connected equipment over a wide range of surge events.The typical application field of a Varistor/MOV is to limit the voltage from a power source, for example, clamping or static protection. It can be also used to supply a constant voltage or current to a circuit with varying incoming power sources, as well as limit the current flowing in the circuit. Other typical applications and usage of a Varistor/MOV include filtering, interference suppression, and transient protection.The working principle of the V321CA40PS is based on its ability to conduct and absorb surge energy when triggered by a voltage spike. When connected to a circuit, the Varistor/MOV will ‘clamp’ the voltage to a predetermined level. This ensures that the surge does not reach damaging levels on the circuit. Once triggered, the Varistor/MOV will return to its non-conductive state.When choosing a Varistor/MOV, it is important to understand its operating parameters and ensure that it is suitable for the intended application. The key parameters include peak pulse current rating, maximum clamping voltage, leakage current, capacitance, and operating temperature range. It is also important to ensure the appropriate environmental rating, such as the UL 1449, UL 96A, and their equivalent ratings. The V321CA40PS has a maximum clamping Voltage of 400V, a peak current rating of 8A, and a minimum leakage current of 5µA. It meets all safety standards, so it can be used in all the applications mentioned before.In conclusion, the V321CA40PS is a powerful Varistor/MOV, which can be used for static protection, filtering, and transient protection due to its low leakage current, high peak current rating, and maximum clamping voltage. It is suitable for a wide range of applications, and is designed to provide reliable surge protection.
