Overview
The MU1005-221Y is a high impedance ferrite chip bead manufactured by Bourns Inc. It features a 0402 (1005 metric) surface mount package with dimensions of 1 mm length and 0.5 mm width. The component provides an impedance of 220 ohms with a tolerance of 25%. It supports a maximum DC current of 100 mA and has a maximum DC resistance of 400 mohms. The device operates within a temperature range of -55°C to +125°C and complies with RoHS standards.
Feature Summary
- Provides high impedance for effective electromagnetic interference filtering in compact circuits
- Utilizes a small 0402 surface mount footprint for space-constrained applications
- Designed for stable performance across a wide industrial temperature range
Applications
- EMI filtering in power supply lines
- Signal line noise suppression
- Voltage regulation circuit protection
Procurement Notes
Verify the specific datasheet version for the MU1005-221Y to confirm impedance characteristics at target frequencies. Ensure compatibility with standard SMD reflow soldering profiles. Check for moisture sensitivity level requirements during storage and handling. Confirm RoHS compliance status if required by project specifications. Validate that the 100 mA current rating meets the operational load conditions.
Selection Notes
Select this component when a compact ferrite bead is needed for EMI suppression in tight spaces. The 0402 package size allows for high-density PCB layouts. Consider the 220 ohm impedance value for the specific frequency range requiring attenuation. Ensure the 100 mA current rating aligns with the circuit's maximum DC current to prevent saturation or overheating.
Part Context
This part belongs to the MU series of high impedance chip ferrite beads from Bourns. These components are designed for general-purpose EMI filtering in consumer electronics and industrial equipment. The series offers various impedance values and package sizes to suit different design constraints while maintaining consistent electrical performance characteristics.
Replacement Considerations
Consult official Bourns documentation for direct cross-references. Verify that any substitute maintains the 0402 footprint, 220 ohm impedance, and 100 mA current rating. Ensure thermal and mechanical compatibility before implementation.
