B41856D8687M009 is a high-quality aluminum electrolytic capacitor manufactured by TDK, a global leader in electronic components. This passive component is specifically designed for single-ended (radial) mounting, making it suitable for a wide array of electronic circuits where reliable energy storage and filtering are critical. Aluminum electrolytic capacitors are known for their high capacitance values in a relatively small form factor, making them indispensable in power supplies, audio equipment, and various industrial applications.

Key Specifications

The B41856D8687M009 capacitor boasts several key attributes that define its performance and suitability for specific applications. Its primary characteristic is a capacitance of 680µF (microfarads) combined with a voltage rating of 63V DC. The capacitance value indicates the component’s ability to store electrical charge, with 680µF being a substantial value suitable for smoothing rectified DC voltage, filtering noise, or providing energy reserves in power circuits. The 63V DC voltage rating signifies the maximum continuous DC voltage that can be applied across the capacitor without risking dielectric breakdown, ensuring robust operation in circuits operating below this threshold. The physical dimensions are also crucial for design and integration: an 18mm diameter x 20mm length. This compact radial form factor allows for efficient use of PCB space, particularly in designs where component density is a concern, while still accommodating the necessary internal structure for its high capacitance and voltage rating. The ‘Production’ product status confirms that this component is actively manufactured and readily available for new designs and ongoing production needs, ensuring long-term supply stability.
