Key Specifications

The B41856D9337M004 capacitor boasts several key attributes that define its performance and suitability for specific applications:

• Brand: TDK: TDK is a Japanese multinational electronics company known for its high-quality electronic components. Specifying TDK ensures that the component adheres to stringent manufacturing standards and reliability, which is crucial for long-term system performance.
• Category: Capacitors > Aluminum Electrolytic Capacitors: This classification places the component within the broad category of capacitors, further narrowing it down to aluminum electrolytic type. This type is characterized by its relatively high capacitance values per unit volume, making it ideal for power supply filtering and energy storage where space is a consideration.
• Component Type: Aluminum Electrolytic Capacitor: This explicitly states the component’s fundamental nature. Aluminum electrolytic capacitors utilize an aluminum oxide layer as the dielectric, offering high capacitance density and suitability for DC applications, particularly in power filtering.
• Product Status: Production: Indicating ‘Production’ status means that the component is actively manufactured and readily available for new designs and ongoing production, ensuring long-term supply stability.
• Product Name (TDK): Single-Ended (Radial) Capacitors: This TDK-specific product name describes the physical configuration. Single-ended, or radial, capacitors have both leads emerging from the same end of the component body, facilitating easy insertion into printed circuit boards (PCBs) and often used in automated assembly processes.
• Main Characteristic 1: 330µF/100V DC: This is the core electrical specification. 330 microfarads (µF) represents the capacitance value, indicating its ability to store charge. A 100V DC rating signifies the maximum continuous DC voltage that can be applied across the capacitor without breakdown, making it suitable for circuits operating at or below this voltage level. This combination of capacitance and voltage is common for power supply filtering in various electronic devices.
• Main Characteristic 2: 18mm dia x 20mm length: These are the physical dimensions of the capacitor. An 18mm diameter and 20mm length specify the component’s footprint and height, which are critical considerations for PCB layout, enclosure design, and ensuring proper fit within a given electronic assembly.

Features and Benefits

• High Capacitance Density: The B41856D9337M004 offers a substantial 330µF capacitance in a compact 18x20mm package, providing efficient energy storage and filtering capabilities without consuming excessive board space.
• Reliable Performance at 100V DC: Designed for robust operation, this capacitor can reliably handle DC voltages up to 100V, making it suitable for a wide range of power supply and industrial control applications where stable voltage handling is critical.
• Single-Ended (Radial) Design: The radial lead configuration simplifies through-hole mounting on PCBs, allowing for straightforward manual or automated assembly processes and ensuring secure mechanical attachment.
• Manufactured by TDK: As a product from TDK, users benefit from the assurance of high-quality materials, consistent manufacturing processes, and rigorous testing, leading to enhanced reliability and a longer operational lifespan for end products.
• Stable Electrical Characteristics: TDK’s expertise ensures that the B418856D9337M004 maintains stable capacitance and low equivalent series resistance (ESR) over its operational temperature range, contributing to efficient power conversion and reduced ripple.

Typical Applications

• Power Supply Filtering: This capacitor is ideally suited for smoothing rectified AC voltage in linear and switching mode power supplies (SMPS). Its 330µF capacitance effectively reduces ripple voltage, providing a stable DC output for sensitive electronic circuits.
• DC-DC Converters: In DC-DC converter designs, the B41856D9337M004 can be used for input and output filtering, helping to stabilize voltage rails, reduce noise, and improve the overall efficiency and transient response of the converter.
• Industrial Control Systems: Given its robust voltage rating and TDK reliability, it finds application in industrial automation equipment, motor drives, and programmable logic controllers (PLCs) where stable power delivery and noise suppression are paramount for reliable operation in harsh environments.
• Audio Amplifiers and Consumer Electronics: In audio applications, these capacitors can be used for power supply decoupling and signal coupling, contributing to cleaner audio output by filtering out unwanted noise and ensuring stable power delivery to amplifier stages.
• LED Lighting Drivers: For high-power LED lighting applications, the B41856D9337M004 can serve as a bulk capacitor in the driver circuit, helping to store energy and smooth the DC voltage supplied to the LED arrays, improving light quality and driver longevity.
