MMZ1005F221ET000

Overview

The TDK MMZ1005F221ET000 is a surface-mount ferrite bead from the MMZ-E Auto series, designed for signal line noise suppression. It features an impedance of 220 Ohms at a test frequency of 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 150 mA and has a maximum DC resistance of 2.3 Ohms. It operates within a temperature range of -55°C to +125°C. The device utilizes a 0402 (1005 metric) package with dimensions of 1.00 mm length, 0.50 mm width, and 0.50 mm height.

Feature Summary

• Automotive-grade reliability certified under AEC-Q200 standards
• Compact 0402 footprint optimized for space-constrained layouts
• High impedance characteristics for wide-band noise attenuation

Applications

• Signal line noise suppression in automotive electronics
• EMI filtering for high-speed digital circuits
• Power supply noise reduction in compact modules

Procurement Notes

Verify the specific suffix ET000 against official TDK documentation to confirm packaging type and reel specifications. Ensure the MMZ-E Auto series designation aligns with project requirements for automotive qualification. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status before procurement.

Selection Notes

Select this component when designing for automotive applications requiring AEC-Q200 compliance. The 150 mA current rating suits low-power signal lines rather than high-current power rails. The 220 Ohm impedance provides effective attenuation at 100 MHz while maintaining low DC resistance to minimize signal loss. Ensure PCB layout accommodates the 0402 package dimensions for proper soldering.

Part Context

This ferrite bead belongs to the MMZ-E Auto series, which is specifically engineered for automotive electronic systems. The series offers various impedance values within the standard 0402 package size. It serves as a passive component for electromagnetic interference suppression in vehicles, complementing other TDK passive components like capacitors and resistors in complex circuit designs.

Replacement Considerations

Consult official TDK substitution guides for equivalent parts within the MMZ or MPZ series. Verify that any alternative maintains the same AEC-Q200 certification and 0402 package dimensions. Ensure impedance and current ratings match or exceed original design specifications.
