Key Specifications

The attributes of the B43547A6157M087 capacitor are essential for understanding its capabilities and suitability for specific designs:

• Brand: TDK – TDK is a renowned Japanese multinational electronics company known for its high-quality electronic components, ensuring reliability and performance for critical applications.
• Category: Capacitors > Sub Category: Aluminum Electrolytic Capacitors – This classification defines the fundamental type of component. Aluminum electrolytic capacitors are polarized, offering high capacitance values in a relatively small volume, making them ideal for DC applications where large amounts of charge storage or ripple current filtering are needed.
• Component Type: Aluminum Electrolytic Capacitor – Reaffirms its specific construction and operational principles, distinguishing it from other capacitor types like ceramic or film capacitors.
• Product Status: Production – Indicates that this component is actively being manufactured and is readily available for new designs and ongoing production, ensuring long-term supply stability.
• Product Name (TDK): Snap-in, Multi Pin, Large Size Capacitors – This TDK-specific product name highlights key physical and functional characteristics. “Snap-in” refers to its mounting style, providing secure mechanical attachment to PCBs without additional hardware. “Multi Pin” suggests enhanced stability and current handling capabilities. “Large Size” implies its capacity for higher voltage and capacitance ratings, suitable for power electronics.
• Main Characteristic 1: 150µF/500V DC – This is the core electrical specification. 150 microfarads (µF) represents the capacitance, indicating its energy storage capacity. 500V DC is the maximum DC voltage the capacitor can safely withstand, making it suitable for high-voltage power supply applications, including those derived from rectified AC mains.
• Main Characteristic 2: 25mm dia x 45mm length – These are the physical dimensions of the capacitor. A diameter of 25mm and a length of 45mm define its footprint and height, which are critical considerations for PCB layout and enclosure design, especially in space-constrained applications.

Features and Benefits
