MPC1250LR50C KEMET

NOT FOR NEW DESIGN SMD Inductors Large-Current Power Inductors MPC Overview The KEMET MPC metal composite inductors are designed for use in power supplies with high ripple current. These inductors offer a superior saturation current when compared to technologies based on ferrite cores. Their low height makes them ideal in applications with thin profile requirements. Also, the flat wire used in the design of the MPC enables high ripple current carrying capabilities. Applications Switching DC-DC power supplies Notebook computers Tablets Embedded computer systems HDTVs DVD and BluRay players Part Number System MPC 0740 L R42C Series Size Code Inductor Inductance Code H MPC 0730 R = decimal point 0740 Examples: 0750 R42C = 0.42 H 1040 1R0C = 1.0 H 1055 1250 One world.
