MMZ0402S241CT000

Overview

The TDK MMZ0402S241CT000 is a surface-mount ferrite bead designed for general signal line applications. It features an impedance of 240 Ohms at a test frequency of 100 MHz with a tolerance of ±25%. The component supports a maximum DC current rating of 200 mA and has a maximum DC resistance of 1 Ohm. It operates within a temperature range of -55°C to +125°C. The physical dimensions are 0.4 mm in length, 0.2 mm in width, and 0.2 mm in height, corresponding to the 01005 (0402 metric) package.

Feature Summary

• Provides electromagnetic interference suppression for high-speed digital signals
• Compact footprint suitable for dense printed circuit board layouts
• Stable performance across extended industrial temperature ranges

Applications

• High-speed data bus filtering
• Clock signal noise attenuation
• General-purpose signal line protection

Procurement Notes

Verify the specific suffix CT000 against official TDK documentation to confirm packaging type and reel specifications. Ensure the selected variant matches the required impedance tolerance and current rating for the target application. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm authenticity and availability status before finalizing procurement orders.

Selection Notes

Select this component when space constraints require a 01005 package size. Evaluate the 200 mA current rating against peak signal line currents to prevent saturation. Confirm that the 240 Ohm impedance value effectively attenuates the targeted noise frequencies at 100 MHz without excessive signal degradation for the specific circuit design requirements.

Part Context

This component belongs to the TDK MMZ series of chip beads. The series offers various impedance values and current ratings in standard metric packages. The MMZ0402 designation indicates the specific 0402 metric case size, distinguishing it from larger variants like the MMZ1005 series while maintaining similar functional characteristics for compact electronics.

Replacement Considerations

Direct substitutes include other TDK MMZ series parts with identical 0402 dimensions and matching electrical parameters. Verify impedance and current ratings match exactly. Check for equivalent package compatibility and thermal characteristics before integrating alternative components into the existing design.
