Key Specifications

The attributes of the B43268A5277M062 capacitor are crucial for understanding its performance and suitability for specific designs:

• Brand: TDK – TDK is a renowned Japanese multinational electronics company known for its high-quality electronic components, magnetic products, and storage devices. Their brand signifies reliability and advanced engineering in the passive components market.
• Category: Capacitors – This broadly classifies the component as a device capable of storing electrical energy in an electric field. Capacitors are fundamental building blocks in almost all electronic circuits.
• Sub Category: Aluminum Electrolytic Capacitors – This specifies the dielectric material and construction type. Aluminum electrolytic capacitors are known for their high capacitance values in a relatively small volume, making them ideal for power supply filtering, energy storage, and coupling applications, particularly at lower frequencies.
• Component Type: Aluminum Electrolytic Capacitor – Reaffirms its specific type, highlighting its construction with an aluminum anode and a liquid electrolyte, which provides the high capacitance density.
• Product Status: Production – Indicates that the 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 internal product name provides insight into its physical characteristics and mounting style. “Snap-in” refers to its terminal design, allowing for quick and secure mounting onto PCBs without soldering, while “Multi Pin” suggests enhanced stability and current handling. “Large Size” indicates its physical dimensions, often correlating with higher capacitance and voltage ratings.
• Main Characteristic 1: 270µF/450V DC – This is the core electrical specification. 270 microfarads (µF) represents its capacitance, the amount of charge it can store. 450V DC is its maximum rated DC voltage, meaning it can safely operate in circuits with up to 450 volts direct current. This combination of high capacitance and high voltage makes it suitable for power factor correction, DC link applications, and high-voltage power supplies.
• Main Characteristic 2: 25.4mm dia x 45mm length – These are the physical dimensions of the capacitor. A diameter of 25.4mm (approximately 1 inch) and a length of 45mm define its footprint and height. These dimensions are critical for mechanical design, PCB layout, and enclosure fitting, especially in space-constrained applications.
