Overview
The MMZ1005Y241CT000 is a multi-layer ferrite bead from the TDK MMZ series, designed for surface-mount applications in the 0402 (1005 metric) package. It provides an impedance of 240 Ohms at a test frequency of 100 MHz with a tolerance of ±25%. The component supports a maximum DC current of 300 mA and exhibits a maximum DC resistance of 260 mOhms. It operates within a temperature range of -55°C to +125°C.
Feature Summary
- Multi-layer ceramic construction for compact high-frequency noise suppression
- Designed for general signal line protection in SMD/SMT configurations
- Capable of handling specified DC bias currents without saturation
Applications
- General signal line filtering
- High-frequency noise suppression in compact electronic devices
- Power supply input/output decoupling
Procurement Notes
Verify the specific suffix CT000 against official TDK documentation to confirm reel or cut-tape packaging requirements. Ensure the ordering part number matches the exact impedance and current ratings required for the target circuit design. Cross-reference the RoHS status and environmental certifications as needed for compliance.
Selection Notes
Select this component when space constraints require a 0402 footprint for ferrite beads. The 240 Ohm impedance at 100 MHz targets specific noise frequencies. Verify that the 300 mA current rating exceeds the maximum operating current of the protected line to prevent excessive heating or performance degradation.
Part Context
This component belongs to the TDK MMZ series of ferrite chip beads. These components are widely used in consumer electronics and industrial equipment for EMI suppression. The MMZ series offers various impedance values and current ratings within standard metric packages to suit diverse PCB layout needs.
Replacement Considerations
Check for direct substitutes such as MMZ1005S241HT000, which shares the 0402 package but may differ in current rating and impedance characteristics. Verify compatibility with existing footprints and thermal management requirements before substitution.
