MU1608-471Y

Overview

The MU1608-471Y is a high impedance ferrite chip bead manufactured by Bourns Inc. It features a 0603 (1608 metric) surface mount package with dimensions of 1.6 mm length, 0.8 mm width, and 0.8 mm height. The component provides an impedance of 470 Ohms at a test frequency of 100 MHz with a tolerance of 25%. It supports a maximum DC current of 350 mA and has a maximum DC resistance of 450 mOhms. The device operates within a temperature range of -55°C to +125°C.

Feature Summary

• Provides high impedance characteristics for effective noise suppression in signal and power lines
• Utilizes a compact 0603 surface mount footprint for space-constrained PCB designs
• Engineered for stable performance across a wide industrial temperature range

Applications

• Noise filtering on power supply lines
• Signal line interference suppression
• EMI reduction in compact electronic modules

Procurement Notes

Verify the specific datasheet version and RoHS compliance status directly with Bourns or authorized distributors before integration. Confirm that the 0603 package dimensions and terminal configuration match the target PCB land pattern. Ensure the 350 mA current rating and 470 Ohm impedance specifications align with the circuit requirements to prevent saturation or excessive signal attenuation.

Selection Notes

Select this component when a small form factor is required for EMI suppression in low-current applications. The 0603 size offers a balance between physical footprint and electrical performance. Consider the 450 mOhm DC resistance impact on voltage drop if used in sensitive power rails. Verify compatibility with standard reflow soldering profiles for SMD/SMT assembly processes.

Part Context

This part belongs to the Bourns MU series of ferrite chip beads, designed for general-purpose noise suppression. The MU series utilizes advanced ferrite materials to provide high impedance over a broad frequency spectrum. These components are commonly used in consumer electronics and industrial equipment where space-saving surface mount solutions are necessary for signal integrity management.

Replacement Considerations

Cross-reference with other 0603 ferrite beads offering similar 470 Ohm impedance at 100 MHz. Verify equivalent current ratings and DC resistance values to ensure circuit compatibility. Check for pinout and dimensional matches to avoid PCB redesign requirements during substitution.
