B41821A4107M007 is an Aluminum Electrolytic Capacitor manufactured by TDK, a globally recognized leader in electronic components. This passive component plays a crucial role in various electronic circuits by storing electrical energy and then releasing it as needed, performing functions such as filtering, smoothing, coupling, and decoupling. Aluminum electrolytic capacitors are particularly valued for their high capacitance values in a relatively small form factor, making them indispensable in power supply units, audio amplifiers, and motor control systems. TDK’s commitment to quality ensures that even obsolete components like the B41821A4107M007 maintain a standard of reliability suitable for replacement or legacy system maintenance.

Key Specifications

The B41821A4107M007 is identified by several key attributes that define its characteristics and intended use. The Brand, TDK, signifies its origin from a reputable manufacturer known for its engineering excellence and stringent quality control processes in the electronics industry. The Category, Capacitors, broadly classifies its function as an energy storage device. More specifically, its Sub Category as Aluminum Electrolytic Capacitors indicates its construction type, which utilizes an aluminum anode and a liquid electrolyte to achieve high capacitance density. The Component Type, Aluminum Electrolytic Capacitor, reiterates its fundamental nature and role in circuits. A critical attribute is its Product Status, which is listed as Obsolete. This status means that while the component is no longer in active production by the manufacturer, it may still be available through distributors for existing designs, repairs, or specific legacy applications. Finally, the Product Name (TDK), Single-Ended (Radial) Capacitors, describes its physical configuration, indicating that both leads emerge from one end of the capacitor body, a common form factor for through-hole mounting on printed circuit boards.
