Fixed Inductors Procurement Notes
This specific part number is officially obsolete and no longer manufactured by Samsung Electro-Mechanics. Procurement must focus on verified direct substitutes such as Bourns SRN2010TA-R47Y or TDK MLP2520HR47MT0S1. Verify that replacement components match the original electrical specifications and physical dimensions before integration into production designs.
Fixed Inductors Selection Notes
Designers should prioritize components with equivalent inductance values and current ratings when replacing this unit. Ensure the substitute maintains the same shielding characteristics and thermal performance limits. Physical footprint compatibility is critical for existing PCB layouts requiring direct pin-to-pin replacement without layout modifications.
Fixed Inductors Part Context
The CIG22HR47MAE belongs to the CIG22H series of chip inductors produced by Samsung Electro-Mechanics. This manufacturer specializes in passive electronic components including capacitors and inductors for consumer, industrial, and automotive markets. The series utilizes advanced thin-film technology to achieve high reliability and miniaturization standards required in modern electronics.
Fixed Inductors Replacement Considerations
Direct substitutes include Bourns Inc. SRN2010TA-R47Y and TDK Corporation MLP2520HR47MT0S1. These alternatives offer comparable electrical parameters and package dimensions. Validate supplier documentation to ensure functional equivalence regarding saturation current and DC resistance.
