🔌 Function

The capacitor is used to store electrical energy and provide capacitance to the circuit, contributing to the stabilization and filtering of electrical quantities. Depending on the application, it can be used in power circuits, conversion systems and AC circuits requiring 33 µF at 400 V AC.

The designation MSR25-C-33-40 follows the series nomenclature: 33 indicates the capacitance in µF, while 40 identifies the 400 V AC voltage class.

📐 Construction

This model belongs to the C configuration of the MSR25 series. For the 33 µF / 400 V version, the technical documentation specifies a configuration with 3 terminals/connections and a cylindrical body approximately 55 mm in diameter and 147 mm in height, with an M8 screw terminal.

🌡️ Operating Conditions

The MSR25 series is designed for an ambient operating temperature range of approximately -25 °C to +85 °C. Technical documentation also specifies parameters such as maximum current, dv/dt, equivalent resistance and service life, which depend on the specific capacitor configuration.

⚠️ Safety Note

A 400 V AC capacitor can retain a dangerous electrical charge even after the circuit has been disconnected. It must therefore be handled, discharged and tested only using appropriate electrical safety procedures.
