Overview
The Bourns MH1608-800T is a surface-mount ferrite bead designed for electromagnetic interference (EMI) suppression in compact electronic circuits. It features a 0603 (1.6mm x 0.8mm) package with a maximum height of 1.00mm. The component provides an impedance of 80 Ohms at a test frequency of 100 MHz, with a tolerance of +/-25%. It supports a maximum DC current of 3A and has a maximum DC resistance of 30 mOhms. The device operates within a temperature range of -55°C to +125°C.
Feature Summary
- Provides effective high-frequency noise attenuation through ferrite material properties
- Supports high current loads up to 3A without saturation
- Compact 0603 footprint enables dense PCB layout integration
Applications
- Power line filtering in portable devices
- Signal integrity enhancement in high-speed digital circuits
- EMI suppression on data lines in consumer electronics
Procurement Notes
Verify the specific datasheet version for the MH1608-800T to confirm RoHS compliance status and exact electrical tolerances. Ensure that the selected supplier provides traceable documentation matching the manufacturer's specifications. Cross-reference the impedance value at 100 MHz against circuit requirements to validate performance suitability.
Selection Notes
Select this component when space constraints require a 0603 package size while maintaining a 3A current rating. The 80 Ohm impedance at 100 MHz makes it suitable for suppressing noise in frequencies around that range. Consider the low DC resistance of 30 mOhms to minimize voltage drop and power loss in power delivery paths.
Part Context
This part belongs to the MH1608-T series of ferrite beads from Bourns. The series offers various impedance values within the same physical footprint, allowing designers to standardize board layouts while adjusting filtering characteristics. The MH1608-800T specifically targets applications requiring moderate impedance with high current handling capabilities.
Replacement Considerations
The Eaton MFBM1V1608-800-R is a documented alternative with similar 80 Ohm impedance but rated for 2.5A max current and 60 mOhm DCR. Verify thermal performance and current derating curves before substitution.
