Technical Specifications:

The SDS1306T-221M-N features a 22µH inductance with a tolerance of ±20%. It is designed for a saturation current of approximately 2.8A and a rated current of 2.4A. The DC resistance (DCR) is typically around 0.07 Ohms. The shielded construction minimizes electromagnetic interference (EMI), making it suitable for sensitive applications.

The core material is typically a ferrite composition optimized for power applications, providing high saturation characteristics and low core losses. The inductor is constructed with a robust winding and termination to ensure mechanical stability and reliable electrical connections.

It is commonly used in step-up (boost) and step-down (buck) DC-DC converters, as well as in EMI filters to suppress unwanted noise in electronic circuits. The inductor's compact size allows it to be integrated into dense circuit boards without significantly increasing the overall size of the device.
