Overview
The MI0805K400R-10 is a single-line ferrite bead from the Laird MI series, designed for EMI filtering in surface-mount applications. It features an 0805 (2012 metric) package with dimensions of 2.00mm x 1.25mm and a maximum height of 0.90mm. The component provides an impedance of 40 Ohms at 100 MHz and supports a rated current of 1.5A. Its maximum DC resistance is specified at 60 milliohms. It operates within a temperature range of -40°C to 125°C and complies with RoHS3 standards.
Feature Summary
- Provides electromagnetic interference suppression through high impedance characteristics at specific frequencies.
- Supports direct surface-mount installation on printed circuit boards.
- Designed for use in both power supply and signal line filtering applications.
Applications
- Power supply line filtering
- Signal line noise suppression
Procurement Notes
Verify the manufacturer part number against official datasheets to ensure accuracy. Confirm that the required impedance value of 40 Ohms at 100 MHz matches the design specifications. Check compliance requirements, specifically RoHS3 status, against project constraints. Ensure the 1.5A current rating is sufficient for the target application's operational limits before procurement.
Selection Notes
Select this component when a 40 Ohm impedance at 100 MHz is required for EMI reduction. The 0805 package size is suitable for standard surface-mount assembly processes. Verify that the 1.5A current handling capacity meets the circuit's maximum load requirements. Consider the low DC resistance to minimize voltage drop and power loss in the signal path.
