The TDK SPM4020T-3R3M-CA is a surface mountable, shielded power inductor from the SPM4020T-CA series. It features a drum core construction with wirewound technology and an iron powder core material.
This inductor offers a nominal inductance of 3.3µH with a tolerance of ±20%. It is rated for a DC current of 2.4A (based on self-temperature rise) and 2.8A (based on inductance change). The maximum DC resistance is 123mOhm. The operating temperature range is -40°C to +125°C.
The component has a compact footprint with dimensions of 4.4mm x 4.1mm and a maximum height of 2.0mm. Its design is suitable for automatic mounting in tape and reel packaging. Applications include notebook computers, VRMs, cellular phones, HDDs, and car accessories.
Key electrical specifications include a test frequency of 100kHz for inductance measurement, with a typical DCR of 17.7mOhm at 0A and 10.6mOhm at Idc 2.
