Overview
The MMZ1005D241CT000 is a single-channel ferrite chip bead from the TDK MMZ series, designed for high-speed signal line applications. It features a 0402 (1005 metric) surface-mount package with dimensions of 1.00mm length, 0.50mm width, and 0.50mm height. The component provides an impedance of 240 Ohms at a test frequency of 100 MHz with a tolerance of 25%. It supports a maximum DC current of 200mA and has a maximum DC resistance of 900 mOhms. The device operates within a temperature range of -55°C to +125°C.
Feature Summary
- Designed for high-speed signal line noise suppression
- Standardized size compatible with automatic assembly equipment
- Supports both flow and reflow soldering methods
Applications
- High-speed digital signal lines
- General electronic circuit noise filtering
- Automotive grade electronics requiring AEC-Q200 compliance
Procurement Notes
Verify the specific suffix CT000 against official TDK documentation to confirm packaging type and availability status. Ensure the selected variant matches the required impedance and current ratings for the target application. Cross-reference the manufacturer part number with authorized distributor lists to confirm authenticity and sourcing channels before procurement.
Selection Notes
Select this component when a compact 0402 footprint is required for high-frequency noise attenuation on signal lines. The 240 Ohm impedance at 100 MHz suits general high-speed data transmission protection. Verify that the 200mA current rating meets the circuit's operational requirements and that the 900 mOhm DC resistance does not cause excessive voltage drop in the design.
Part Context
This component belongs to the TDK MMZ series of ferrite beads, which are widely used for EMI suppression in portable devices and automotive electronics. The MMZ series offers standardized sizes to facilitate automated placement. The MMZ1005D241CT000 specifically utilizes the 1005 metric case size, balancing performance with space constraints in dense PCB layouts.
Replacement Considerations
Consult official TDK substitution guides for verified equivalents. Generic cross-references may not match the specific impedance characteristics or thermal performance of the original component.
