Overview
The TDK MMZ1608Q221BTA00 is a single-line ferrite chip bead designed for signal line applications. It features a 0603 (1608 metric) surface-mount package with dimensions of 1.6 mm length, 0.8 mm width, and 0.8 mm height. The component provides an impedance of 220 Ohms at a test frequency of 100 MHz. It supports a maximum DC current rating of 500 mA and has a maximum DC resistance of 400 mOhms. The device operates within a temperature range of -55°C to +125°C and carries a tolerance of 25%.
Feature Summary
- Engineered specifically for high-speed signal line filtering applications.
Applications
- High-speed digital signal processing circuits
- Noise suppression in sensitive signal lines
- Electromagnetic interference reduction in compact electronic modules
Procurement Notes
Verify the specific suffix BTA00 against official TDK documentation to confirm packaging configuration and compliance status. Ensure that the 0603 footprint matches the target PCB layout constraints. Confirm that the 500 mA current rating meets the operational requirements of the intended circuit path without exceeding thermal limits under worst-case conditions.
Selection Notes
Select this component when a 220 Ohm impedance at 100 MHz is required for noise attenuation in space-constrained designs. The 0603 package allows for dense board layouts. Verify that the 400 mOhm DC resistance does not introduce unacceptable voltage drops in the signal path. Ensure the operating temperature range aligns with the environmental conditions of the final assembly.
Part Context
This part belongs to the TDK MMZ series of ferrite beads, which are widely used for EMI suppression. The MMZ series offers various impedance values and current ratings in standard packages. The Q221 designation indicates the specific impedance characteristic, while the 1608 code defines the physical size. This series is known for consistent performance in consumer and industrial electronics.
Replacement Considerations
The MMZ1608Y221B is identified as a previous version or alternative numbering for similar specifications. Verify electrical parameters such as DC resistance, which may differ slightly between revisions. Ensure that any substitute maintains the same 0603 footprint and impedance profile to guarantee compatibility with existing designs.
