Product Description

The TDK B82422A1472K100 is a high-performance wirewound surface mount inductor with a ferrite core, designed in a 1210 (3.2mm × 2.5mm) package. This device is engineered for precise and stable inductance, making it an ideal choice for applications demanding high reliability, such as automotive, industrial, and consumer electronic circuits.

With an inductance value of 4.7 microhenries (μH) and a tolerance of ±10%, this inductor ensures accurate performance in filtering, energy storage, and signal coupling circuits. Its wirewound, unshielded construction provides a high quality factor (minimum Q of 27) and a maximum self-resonant frequency of 110MHz, making it suitable for high-frequency and RF applications where minimal losses and stable operation are essential.

The B82422A1472K100 supports a maximum DC current of 150mA and features a low DC resistance of 2.2Ω, balancing current capability and minimized power loss. Its robust ferrite core contributes to magnetic efficiency and thermal stability across a broad operating temperature range from -55°C to 125°C. Automotive AEC-Q200 standard qualification ensures this inductor meets stringent reliability requirements for use in automotive and industrial environments.

With dimensions of 3.2mm (length) by 2.5mm (depth) by 2.0mm (height) and a moulded case, the inductor is optimized for space-constrained surface mount PCB layouts. Pin count of 2 and standard soldering terminals ensure compatibility with modern SMT assembly processes, while the tape-and-reel packaging supports automated production lines.

The inductor features RoHS compliance for environmental compatibility and uses a reliable solder termination style. The unshielded design enables a low profile and easy integration, though adequate PCB layout practices are recommended to minimize EMI in sensitive circuits.

Applications for the TDK B82422A1472K100 include DC-DC converters, signal filtering, automotive electronics, mobile and wireless devices, and power management modules. It is particularly well-suited for demanding designs that require high performance, thermal stability, and reliable long-term operation.

Engineers and product designers benefit from its combination of compact footprint, reliability, and proven TDK quality, ensuring optimal integration in advanced PCB assemblies.
