TDK B41888 Series Electrolytic Capacitor, 470µF, 50V, Radial, 10000h @105°C

The TDK B41888 Series is a high-performance single-ended aluminium electrolytic capacitor designed for demanding industrial and automotive applications. Engineered for exceptional reliability, it offers a capacitance of 470µF at a 50V DC rating with a ±20% tolerance, ensuring stable performance in critical circuits. Its construction utilises a specially etched aluminium anode foil, which maximises surface area to deliver one of the highest volumetric capacitance ratings available, providing an excellent cost-to-performance ratio.

A key feature of this long-life grade component is its robust 10,000-hour operational lifespan at a continuous 105°C, making it suitable for high-temperature environments. It boasts a low impedance at high frequencies and a high ripple current capability of 1.8A, essential for smoothing and filtering in power supply designs. The radial-leaded, charge-discharge proof, and polar design ensures secure and correct PCB mounting.

Housed in a durable aluminium case with a PET insulating sleeve, the capacitor includes clear minus-pole marking for easy installation and a safety vent for operational integrity. It is fully compliant with the AEC-Q200 standard for automotive electronics and meets the IEC 60384-4 sectional specification, having passed rigorous IEC climatic category tests (55°C/+105°C/56 days damp heat).

Primary Applications

This capacitor is ideally suited for frequency converters, wind power and solar inverters, professional power supplies and UPS systems, medical equipment, professional photoflash units, and a wide range of automotive electronic applications. Its combination of long life, high ripple current handling, and automotive qualification makes it a dependable choice for engineers designing reliable, long-lasting products.
