MH1608-301T

Overview

The Bourns MH1608-301T 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, 0.8 mm width, and 0.8 mm height. The component provides an impedance of 300 Ohms at a test frequency of 100 MHz with a tolerance of ±25%. It supports a maximum DC current rating of 2.2 A and has a maximum DC resistance of 0.07 ohms. The device operates within a temperature range of -55°C to +125°C.

Feature Summary

• High current handling capability suitable for power and signal lines
• Compact 0603 surface-mount footprint for space-constrained designs
• Effective electromagnetic interference suppression at 100 MHz

Applications

• Power line filtering in portable electronics
• Signal line protection in automotive systems
• EMI suppression in DC-DC converter circuits

Procurement Notes

Verify the specific suffix 'T' against official Bourns documentation to confirm tape-and-reel packaging and exact electrical tolerances. Ensure the selected part matches the required 2.2A current rating and 0.07 ohm DCR specifications for your circuit design. Cross-reference the impedance value at 100 MHz to validate compatibility with your EMI filtering requirements.

Selection Notes

Select this component when a compact ferrite bead capable of handling 2.2A is required for EMI suppression. The 0603 package allows for dense PCB layouts. Verify that the 300 Ohm impedance at 100 MHz aligns with the noise frequencies present in the application. Consider the low DC resistance of 0.07 ohms to minimize voltage drop and power loss in high-current paths.

Part Context

The MH1608-301T belongs to Bourns' MH series of high-current chip ferrite beads. This series is engineered for robust performance in demanding environments, offering reliable EMI suppression while maintaining low insertion loss. The components are widely used in consumer electronics, industrial controls, and automotive applications where space and current capacity are critical constraints.

Replacement Considerations

Check for MH1608-301Y as a potential variant with similar form factor but verify current ratings and packaging differences. Consult Bourns datasheets for direct pin-compatible substitutes within the MH1608 series that meet identical 300 Ohm impedance and 2.2A current specifications.
