Overview
The Bourns MH1608-181Y is a high-current chip ferrite bead in the MH series, designed for surface-mount applications. It features a 0603 (1608 metric) package with dimensions of 1.6 mm length and 0.8 mm width. The component provides an impedance of 180 ohms at 100 MHz with a tolerance of ±25%. It supports a maximum DC current of 2.0 A and has a maximum DC resistance of 100 milliohms. Operating temperatures range from -55°C to +125°C.
Feature Summary
- High resistance to heat and humidity
- Resistance to mechanical shock and pressure
- Accurate dimensions for automatic surface mounting
Applications
- Power supplies
- Battery chargers
- Portable devices
- Energy-efficient systems
Procurement Notes
Verify the specific suffix 'Y' corresponds to the required tape and reel packaging configuration as defined by Bourns documentation. Confirm RoHS compliance status matches current regulatory requirements for your target market. Ensure the 0603 footprint aligns with your PCB design rules before finalizing procurement orders.
Selection Notes
Select this component when circuit designs require EMI suppression in compact spaces with significant DC bias currents up to 2.0 A. The 180-ohm impedance at 100 MHz targets common noise frequencies in digital and power circuits. Verify that the low DCR of 100 milliohms meets voltage drop constraints within the signal or power path.
Part Context
This part belongs to the Bourns MH series of high-current chip ferrite beads. The series offers a wide impedance range across various package sizes, allowing designers to balance noise filtering performance with physical space limitations. The MH1608 variant specifically addresses the need for robust filtering in dense surface-mount layouts.
Replacement Considerations
Consult official Bourns cross-reference tools for verified substitutes. Generic equivalents may not match the 2.0 A current rating or 180-ohm impedance profile. Ensure any replacement maintains the 0603 footprint and thermal characteristics to preserve board integrity.
