Overview
The MHC1005S121MBPDG is a surface-mount ferrite bead manufactured by INPAQ Technology Co., Ltd. It features a 0402 (1005 metric) package with dimensions of 1.0 mm length, 0.5 mm width, and 0.5 mm height. The component has a rated current of 1.5 A and a maximum DC resistance of 150 mΩ. Its impedance is specified as 120 Ω at 100 MHz. It operates within a temperature range of -55 °C to +125 °C and complies with RoHS standards.
Feature Summary
- Monolithic inorganic material construction for high reliability
- Closed magnetic circuit design to minimize crosstalk
- Suitable for reflow and wave soldering processes
Applications
- Power line noise suppression
- Signal line noise suppression
- High-frequency electromagnetic interference filtering
Procurement Notes
Verify the specific impedance tolerance and DC resistance values against the official INPAQ datasheet before procurement. Confirm that the 0402 package dimensions align with your PCB footprint requirements. Ensure the 1.5 A current rating meets the operational load of the target circuit. Check for RoHS compliance documentation if required by your manufacturing standards.
Selection Notes
Select this component when space constraints require a 0402 footprint ferrite bead. Choose it for applications requiring 120 Ω impedance at 100 MHz. Ensure the circuit current does not exceed 1.5 A to prevent saturation or excessive heating. Consider the low DC resistance of 150 mΩ for minimal voltage drop in power lines.
Part Context
This part belongs to the MHC series of multilayer chip beads from INPAQ Technology. These components are designed for EMI/EMC solutions in computing, communication, consumer electronics, and automotive sectors. The series offers various sizes and impedance values to address different noise suppression needs efficiently.
Replacement Considerations
Cross-reference with other 0402 ferrite beads offering 120 Ω @ 100 MHz and ≥1.5 A current rating. Verify pin compatibility and physical dimensions match the existing PCB layout. Ensure thermal performance and impedance characteristics are equivalent for seamless integration.
