Overview
The MMZ1005D221ET000 is a surface-mount ferrite chip bead from the MMZ-E series, manufactured by TDK Corporation. It features a 0402 (1005 metric) package with dimensions of 1 mm length and 0.5 mm width. The component provides an impedance of 220 ohms at 100 MHz with a tolerance of 25%. It supports a maximum DC current of 250 mA and has a maximum DC resistance of 1 ohm. The operating temperature range spans from -55°C to +125°C.
Feature Summary
- Designed for signal line filtering applications
- Single-line configuration for compact circuit integration
- Surface mount termination style for automated assembly
Applications
- Signal line noise suppression
- High-frequency interference filtering in compact electronics
Procurement Notes
Verify the specific suffix ET000 against official TDK documentation to confirm packaging details such as reel or cut tape specifications. Ensure the part number matches the exact impedance and current ratings required for your design. Cross-reference with authorized distributors to confirm active lifecycle status and availability. Always consult the latest datasheet for handling and soldering guidelines.
Selection Notes
Select this component when a low-profile 0402 ferrite bead is needed for signal integrity management. The 220-ohm impedance at 100 MHz targets specific high-frequency noise profiles. Verify that the 250 mA current rating exceeds the maximum expected DC load on the protected line. Consider the 1-ohm DC resistance impact on voltage drop within the circuit design constraints.
Part Context
This component belongs to the MMZ-E series of ferrite beads, which are engineered for suppressing electromagnetic interference in electronic circuits. The MMZ1005D221ET000 specifically utilizes a 0402 footprint, allowing for dense PCB layouts. As a passive filter element, it dissipates high-frequency energy as heat while maintaining signal integrity for lower frequencies.
Replacement Considerations
Direct substitutes include other 0402 ferrite beads with 220 ohms impedance at 100 MHz and similar current ratings. Verify mechanical compatibility and electrical performance curves before substitution. Alternative manufacturers may offer comparable parts, but thermal and frequency response characteristics should be validated.
