Key Specifications

This TDK B43611C7827M057 capacitor boasts several critical specifications that define its operational parameters and suitability for various applications:

Brand: TDK – TDK is a renowned Japanese multinational electronics company known for its high-quality electronic components, including capacitors, inductors, and sensors. Opting for a TDK component ensures reliability and adherence to stringent manufacturing standards.

Category: Capacitors – This broadly classifies the component as a device capable of storing electrical energy. Capacitors are fundamental in almost all electronic circuits for filtering, timing, coupling, and energy storage.

Sub Category: Aluminum Electrolytic Capacitors – This specifies the dielectric material used (aluminum oxide) and the electrolyte, which gives these capacitors their high capacitance values in a relatively small volume. They are polarized, meaning they must be connected with the correct polarity.

Component Type: Aluminum Electrolytic Capacitor – Reaffirms its specific construction and operational principle, distinguishing it from other capacitor types like ceramic or film capacitors.

Product Status: Production – Indicates that the component is actively being manufactured and is readily available for new designs and existing production lines, ensuring long-term supply stability.

Product Name (TDK): Snap-in, Multi Pin, Large Size Capacitors – This descriptive name from TDK highlights key physical and functional attributes. “Snap-in” refers to the mounting style, allowing for quick and secure installation onto PCBs. “Multi Pin” suggests multiple terminals for enhanced stability and current handling. “Large Size” implies its capacity for high voltage and capacitance, typically used in power applications.

Main Characteristic 1: 820µF/550V DC – This is arguably the most crucial specification. 820 microfarads (µF) represents the capacitance, indicating its energy storage capacity. 550V DC is the maximum DC voltage that can be continuously applied across the capacitor without breakdown, making it suitable for high-voltage power applications.

Main Characteristic 2: 45mm dia x 60mm length – These are the physical dimensions of the capacitor. 45mm diameter and 60mm length define its footprint and height, which are critical considerations for PCB layout and enclosure design, especially in space-constrained applications.

Features and Benefits

• High Capacitance and Voltage Rating: With 820µF at 550V DC, this capacitor is ideal for high-power applications, providing excellent ripple current handling and energy storage capabilities, which is crucial for stable power delivery.
• Robust Snap-in Design: The snap-in terminals ensure a secure mechanical and electrical connection to the PCB, simplifying assembly and enhancing reliability, particularly in environments subject to vibration.
• Multi-Pin Configuration: Multiple pins offer improved current distribution and thermal performance, reducing equivalent series resistance (ESR) and equivalent series inductance (ESL), leading to better circuit efficiency.
• Long Operational Life: Manufactured by TDK, a leader in electronic components, this capacitor is designed for extended operational life, reducing maintenance costs and improving the overall reliability of the end product.
• Compact for its Rating: Despite its high capacitance and voltage, the 45mm x 60mm dimensions represent an optimized form factor for power applications, allowing for more compact system designs.
