The MHCI04020-1R0M-R8 is a 4.5A 1uH ±20% 27mO SMD power inductor ROHS manufactured by Chilisin. It is constructed using a winding core made of magnetically permeable material that is wrapped with a layer of copper wire. The winding core is then placed inside an EMI shielding can, which is designed to reduce the amount of electromagnetic interference generated by the inductor. The can also helps protect the winding core from damage due to physical contact. The inductance of the MHCI04020-1R0M-R8 is measured in microhenries (uH) and has a tolerance of ±20%. Additionally, it has a rated DC current of 4.5A and DC resistance of 27mOhm. Finally, the MHCI04020-1R0M-R8 is ROHS compliant, meaning that it does not contain any materials that are hazardous to the environment and does not contribute to electronic waste.
