Key Specifications

Brand: TDK
TDK is a renowned Japanese multinational electronics company that manufactures electronic components, recording media, and data storage devices. Their brand signifies quality and reliability in the electronics industry, ensuring that the B43509A2158M080 meets stringent performance and durability standards.

Category: Capacitors; Sub Category: Aluminum Electrolytic Capacitors
This classification precisely identifies the component’s fundamental function and type. Capacitors are passive electronic components that store electrical energy in an electric field. Aluminum electrolytic capacitors, specifically, use an aluminum anode and a liquid electrolyte, offering high capacitance values in a relatively small volume, making them ideal for power filtering and energy storage applications.

Component Type: Aluminum Electrolytic Capacitor
This reiterates the core technology of the component. Aluminum electrolytic capacitors are polarized, meaning they must be connected with the correct polarity (positive to positive, negative to negative) to prevent damage. They are characterized by their ability to store large amounts of charge, making them essential for smoothing out voltage ripples in DC power supplies and providing energy bursts when needed.

Product Status: Production
“Production” status indicates that the B43509A2158M080 is actively being manufactured and is readily available for purchase. This assures buyers of consistent supply and long-term availability for their designs and production needs, without concerns about obsolescence in the near future.

Product Name (TDK): Snap-in, Multi Pin, Large Size Capacitors
This TDK-specific product name highlights key physical and functional attributes. “Snap-in” refers to the mounting style, where pins are designed to snap securely into holes on a printed circuit board (PCB), providing mechanical stability and good electrical contact. “Multi Pin” suggests multiple terminals for enhanced current handling and stability. “Large Size” indicates its physical dimensions, often correlating with higher capacitance and voltage ratings, suitable for demanding power applications.

Main Characteristic 1: 1500µF/200V DC
This specifies the capacitance and rated voltage. 1500 microfarads (µF) is a significant capacitance value, indicating its capacity to store a large amount of electrical charge. The 200V DC rating signifies the maximum continuous DC voltage that can be applied across the capacitor without damage. This combination makes it suitable for applications requiring substantial energy storage and operating at moderate to high DC voltages, common in industrial power supplies and motor control.

Main Characteristic 2: 30mm dia x 45mm length
These are the physical dimensions of the capacitor. A diameter of 30mm and a length of 45mm define its form factor. These dimensions are crucial for mechanical design and PCB layout, ensuring the component fits within the available space in an electronic enclosure. The relatively large size is typical for high-capacitance, high-voltage electrolytic capacitors, reflecting the internal construction required to achieve these electrical characteristics.

• Optimized for Power Applications: Its characteristics are perfectly suited for smoothing rectified AC voltage, filtering noise, and providing energy buffering in power supplies, motor drives, and inverters.
• Multi-Pin Configuration: The multi-pin design (implied by “Multi Pin” in the product name) often provides lower equivalent series resistance (ESR) and better current handling, leading to improved efficiency and reduced heat generation.

Typical Applications

Switch-Mode Power Supplies (SMPS): The B43509A2158M080 is an excellent choice for the input and output filtering stages of SMPS. Its high capacitance helps to smooth out rectified AC voltage, reducing ripple and ensuring a stable DC output. In the output stage, it helps to filter high-frequency noise and provide transient current for load changes, improving overall power supply stability and efficiency.

Industrial Motor Drives: In variable frequency drives (VFDs) and other motor control applications, these capacitors are critical in the DC link. They store energy, filter harmonics, and provide a stable DC bus voltage for the inverter section, which then drives the motor. The 200V rating is suitable for various industrial control systems operating on common line voltages.

Inverters and Converters: For DC-AC inverters used in renewable energy systems (solar, wind) or uninterruptible power supplies (UPS), this capacitor can be used for DC bus filtering. It helps to maintain a stable DC voltage before conversion to AC, improving the quality and efficiency of the inverter output.

Welding Equipment: High-power welding machines often utilize large electrolytic capacitors for energy storage and filtering in their power delivery systems. The B43509A2158M080, with its high capacitance and voltage rating, can contribute to the stable and powerful current delivery required for welding operations.

Audio Amplifiers (Power Supply Section): In high-fidelity audio amplifiers, large electrolytic capacitors are used in the power supply to provide clean, stable DC power to the amplifier stages. This helps to reduce hum and noise, resulting in clearer and more dynamic audio reproduction. The 1500µF capacity is substantial for such applications.
