SPM4020T-R47M-CA Description

Short technical summary and product information.

The TDK Corporation SPM4020T-R47M-CA is a surface mount fixed inductor designed for various electronic applications. It offers a nominal inductance of 470 nH with a tolerance of ±20% at a test frequency of 100 kHz. The inductor is shielded and features a wirewound construction with an iron powder core.

 

Key electrical specifications include a maximum DC resistance (DCR) of 19.5 mOhm and a rated DC current of 6.1 A (typical, based on self-temperature rise). The current handling capability extends to a saturation current of 10.6 A (typical, based on inductance change).

 

This component operates within a temperature range of -40°C to 125°C. Its compact dimensions, measuring 4.40mm in length, 4.10mm in width, and a maximum height of 2.00mm, make it suitable for space-constrained designs. The Nonstandard package type indicates specific packaging requirements.

 

Applications for this inductor include notebook computers, VRMs, cellular phones, HDDs, and car accessories, benefiting from its high power handling capability and flat inductance performance over temperature.
