MH1608-221T

Overview

The MH1608-221T is a surface-mount ferrite bead from the Bourns MH1608 series, designed for high-current 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 220 Ohms at a test frequency of 100 MHz, with a tolerance of ±25%. It supports a maximum DC current of 2.3 A and has a maximum DC resistance of 50 mOhms. The operating temperature range spans from -55°C to +125°C.

Feature Summary

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

Applications

• Power supply output filtering
• Signal line noise suppression
• DC-DC converter input/output stages

Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging if required by assembly equipment. Confirm RoHS compliance status through the official datasheet or manufacturer documentation prior to integration. Ensure the 2.3A current rating aligns with the thermal management capabilities of the target PCB layout to prevent overheating during operation.

Selection Notes

Select this component when a compact form factor is required alongside significant current carrying capacity. The 220 Ohm impedance value targets specific noise frequencies around 100 MHz. Compare the 50 mOhms DCR against voltage drop requirements in the circuit design. Consider the -55°C to +125°C range for environmental robustness compared to standard commercial grade parts.

Part Context

This part belongs to the Bourns MH1608 series of high-current chip ferrite beads. The series is characterized by its ability to manage substantial DC currents within a small surface-mount package. It serves as a passive component for EMI/RFI suppression in modern electronic assemblies where space and current density are critical constraints.

Replacement Considerations

The MH1608-221Y is listed as a parametric equivalent substitute. Verify that the Y suffix variant maintains identical electrical characteristics and physical dimensions before substitution.
