WEIDY CBB21 4.7µF 400V Polypropylene Film Capacitor

Product Description

The WEIDY CBB21 4.7µF 400V Film Capacitor is a metallized polypropylene film capacitor designed for electronic circuits, power electronics, and electrical applications requiring stable capacitance and reliable DC voltage handling. With a capacitance of 4.7µF and a rated voltage of 400V DC, it is suitable for filtering, coupling, and energy-storage applications in compatible circuit designs.

The CBB21 series uses a metallized polypropylene film dielectric. This construction provides low dielectric loss and good electrical stability, making it useful in circuits operating at different frequencies. Polypropylene film capacitors are commonly selected for applications where low losses and consistent electrical performance are important.

The capacitor features a through-hole mounting design with radial leads, allowing direct installation on printed circuit boards. Its lead spacing and physical dimensions should be checked against the PCB footprint before assembly, particularly when replacing an existing capacitor or designing a new circuit.

With its 4.7µF capacitance, the WEIDY CBB21 can be used in DC filtering networks, signal coupling circuits, timing networks, and power-supply designs where the specified capacitance and voltage rating meet the circuit requirements. It can also be used in suitable switching and industrial electronic equipment.

The capacitor is manufactured by WEIDY, a supplier of film capacitors and other electronic components. Its metallized polypropylene construction makes it a practical choice for electronic repair, circuit development, and power-electronics projects.

Important: The 400V rating refers to the capacitor's DC voltage rating. It should not automatically be treated as a 400V AC rating. Always verify the circuit voltage, ripple current, frequency, temperature, and safety requirements before selecting a capacitor.
