Key Specifications

The attributes of the B25838W1107J004 provide a clear understanding of its identity and intended use:

• Brand: TDK – TDK is a renowned Japanese multinational electronics company that manufactures electronic components, recording media, and data-storage devices. Their brand signifies a commitment to quality, reliability, and innovation in the electronics industry, making components like this power capacitor a trusted choice for engineers worldwide.
• Category: Capacitors – Capacitors are fundamental passive electronic components that store electrical energy in an electric field. They are essential in virtually all electronic circuits for various functions, including filtering, energy storage, timing, and coupling/decoupling signals.
• Sub Category: Power Capacitors – Power capacitors are specifically designed for high-power applications, typically in AC systems. They are built to handle significant voltage and current levels, often used for power factor correction, harmonic filtering, and voltage stabilization in industrial, commercial, and utility power systems. Their robust construction differentiates them from general-purpose capacitors.
• Component Type: Power Capacitor – This reiterates its specialized nature, emphasizing its role in power electronics rather than signal processing or low-power applications. It signifies that the component is engineered for durability and performance in demanding electrical environments.
• Product Status: Obsolete – The ‘Obsolete’ status means that TDK no longer actively manufactures this specific part. While new production has ceased, these components may still be available through distributors or in existing stock. For designers, this means considering alternatives for new designs but recognizing its importance for existing systems or specific repair needs.
• Product Name (TDK): Power Capacitors for AC Filtering (MKP cylindrical) – This detailed product name from TDK provides critical context. ‘AC Filtering’ highlights its primary application in removing unwanted AC components from a power supply or signal. ‘MKP’ refers to Metallized Polypropylene Film, a dielectric material known for its excellent electrical properties, high insulation resistance, and low dissipation factor, making it ideal for power applications. The ‘cylindrical’ form factor indicates its physical shape, which is common for power capacitors due to efficient heat dissipation and robust construction.
