B43513B4188M087 B43513B4188M087 Aluminum Electrolytic Capacitor

B43513B4188M087 is a high-performance aluminum electrolytic capacitor manufactured by TDK, a global leader in electronic components. This specific component is designed for demanding applications requiring robust energy storage and filtering capabilities. As a passive component, its primary function is to store electrical energy electrostatically in an electric field, releasing it when needed to smooth voltage fluctuations, couple signals between circuit stages, or provide power supply filtering. TDK’s reputation for quality and reliability ensures that this capacitor meets stringent performance standards for various industrial and commercial uses.

Key Specifications

The attributes of the B43513B4188M087 capacitor are crucial for understanding its suitability for specific circuit designs. The Brand, TDK, signifies a commitment to engineering excellence and consistent product quality. The overarching Category, Capacitors, places it within the fundamental group of energy-storing passive components, while the Sub Category, Aluminum Electrolytic Capacitors, specifies its construction type, known for high capacitance values in a relatively compact size. Its Component Type, Aluminum Electrolytic Capacitor, further refines this, indicating its internal structure and operational principles. The Product Status as ‘Production’ confirms that this is a currently manufactured and readily available part, ensuring long-term supply for new designs and maintenance. The Product Name (TDK), ‘Snap-in, Multi Pin, Large Size Capacitors,’ provides insight into its physical mounting style and general form factor, suggesting ease of installation and suitability for higher power applications. The Main Characteristic 1, ‘1800µF/350V DC,’ is perhaps the most critical specification. 1800 microfarads (µF) represents its capacitance, indicating its ability to store a significant amount of charge, which is vital for filtering ripple in power supplies or providing substantial energy bursts. The 350V DC is its maximum rated voltage, meaning it can safely operate in circuits with DC voltages up to 350 volts without risk of breakdown, making it suitable for higher voltage power conversion stages. Finally, Main Characteristic 2, ’45mm dia x 70mm length,’ describes its physical dimensions. A 45mm diameter and 70mm length indicate a substantial component size, typical for capacitors with high capacitance and voltage ratings, which require more internal volume for the electrolyte and foil structure. These dimensions are essential for mechanical design and PCB layout considerations.
