Key Specifications

The B32529C6472K289 film capacitor boasts several critical specifications that define its performance and suitability for specific applications:

• Brand: TDK – TDK is a globally recognized manufacturer synonymous with quality and innovation in electronic components. Choosing a TDK component assures engineers of high standards in design, manufacturing, and reliability.
• Category: Capacitors > Film Capacitors > Film Capacitors for PCB/Busbar Mounting and Motor Run – This classification highlights the component’s primary function as a capacitor and its specific type as a film capacitor. The sub-category further refines its intended use, indicating its suitability for mounting on printed circuit boards (PCBs) or busbars, and its potential application in motor run circuits where stable capacitance under AC conditions is crucial.
• Component Type: Film Capacitor – Film capacitors utilize a thin plastic film as the dielectric, offering superior performance characteristics such as high insulation resistance, low equivalent series resistance (ESR), and excellent frequency response compared to other capacitor types.
• Product Status: Production – This indicates that the B32529C6472K289 is an active, currently manufactured product, ensuring long-term availability and support for new designs and existing systems.
• Product Name (TDK): Capacitors for RFI Filtering, Smoothing, General Purpose – This descriptive name from TDK itself provides insight into the capacitor’s primary functional roles. RFI (Radio Frequency Interference) filtering involves suppressing unwanted high-frequency noise, smoothing applications aim to reduce ripple in DC power supplies, and general-purpose use covers a wide array of timing, coupling, and decoupling functions in electronic circuits.
• Main Characteristic 1: 0.0047uF, 400V DC – This specifies the capacitance value as 0.0047 microfarads (µF) and the maximum DC voltage rating as 400 volts. The capacitance determines the amount of charge the capacitor can store, while the voltage rating is critical for ensuring the component can safely operate within the circuit’s voltage limits without breakdown.
• Main Characteristic 2: 2.5mm(W) x 6.5mm(H) x 7.3mm(L) – These dimensions provide the physical size of the capacitor, crucial for PCB layout and enclosure design. Its compact form factor allows for integration into space-constrained applications.

Features and Benefits

• High Reliability and Stability: TDK film capacitors are known for their excellent long-term stability and robust performance, ensuring consistent operation over the product’s lifespan and across varying environmental conditions.
• Low Dissipation Factor: The low dissipation factor minimizes energy loss within the capacitor, leading to higher efficiency, less heat generation, and improved overall circuit performance, especially in high-frequency applications.
• Self-Healing Properties: Film capacitors possess self-healing capabilities, meaning minor dielectric breakdowns caused by overvoltage or defects can be repaired internally, preventing catastrophic failure and extending the component’s operational life.
• Versatile Application Range: Designed for RFI filtering, smoothing, and general-purpose use, this capacitor offers broad applicability across various electronic designs, reducing the need for multiple specialized components.
• Compact Form Factor: With dimensions of 2.5mm(W) x 6.5mm(H) x 7.3mm(L), the B32529C6472K289 is suitable for dense PCB layouts and miniaturized electronic devices where space is at a premium.

Typical Applications

• Power Supply Smoothing and Filtering: In DC power supplies, this film capacitor can effectively smooth out voltage ripples, providing a cleaner and more stable DC output for sensitive electronic circuits. Its 400V rating makes it suitable for various AC-DC conversion stages.
• RFI/EMI Suppression: The B32529C6472K289 is ideal for filtering out unwanted radio frequency interference (RFI) and electromagnetic interference (EMI) in electronic equipment, ensuring compliance with EMC standards and preventing signal corruption.
• Motor Run Applications: While typically smaller values are used for motor run, the stability and voltage rating of this film capacitor make it suitable for specific low-power motor control circuits or as part of a larger motor run capacitor bank, providing phase shift for AC motors.
• Timing and Oscillating Circuits: Due to its stable capacitance and low tolerance, this component can be used in precision timing circuits, oscillators, and resonant circuits where accurate frequency generation or timing is critical.
• Signal Coupling and Decoupling: In audio and data communication circuits, it can be used for coupling AC signals between stages while blocking DC, or for decoupling power lines to prevent noise propagation between different circuit blocks.
