B41887A7128M002 B41887A7128M002 Aluminum Electrolytic Capacitor

B41887A7128M002 is a high-quality aluminum electrolytic capacitor manufactured by TDK, a global leader in electronic components. This passive component is designed for a wide range of electronic circuits, offering reliable energy storage and filtering capabilities. Aluminum electrolytic capacitors are known for their high capacitance values in a relatively small form factor, making them essential for power supply smoothing, coupling, decoupling, and timing applications in various electronic devices. The B41887A7128M002 is part of TDK’s extensive line of single-ended (radial) capacitors, engineered for robust performance and longevity in demanding environments.

Key Specifications

The B41887A7128M002 capacitor boasts several critical specifications that define its performance and suitability for specific applications. Its primary characteristic is a capacitance of 1200µF (microfarads) combined with a voltage rating of 35V DC. The capacitance value indicates the amount of electrical charge the capacitor can store, with 1200µF being a substantial value suitable for applications requiring significant energy storage or ripple current filtering. The 35V DC voltage rating specifies the maximum continuous DC voltage that can be applied across the capacitor without causing damage. Exceeding this voltage can lead to dielectric breakdown and component failure, so it’s crucial to select a capacitor with a voltage rating comfortably above the maximum expected operating voltage in the circuit. The physical dimensions of this component are 12.5mm diameter x 25mm length. These dimensions are critical for mechanical design and PCB layout, ensuring the capacitor fits within the available space on a circuit board and aligns with standard component spacing. As an “Aluminum Electrolytic Capacitor” and a “Passive Component,” it plays a fundamental role in circuit design without generating power itself, focusing instead on controlling electrical signals and energy flow. Its “Production” status confirms it is an actively manufactured and readily available component from TDK.
