Overview
The TDK MMZ1608D121BTA00 is a surface-mount ferrite chip bead from the MMZ series, designed for general signal line applications. It features a 0603 (1608 metric) package with dimensions of 1.6mm length, 0.8mm width, and 0.8mm height. The component provides an impedance of 120 Ω at a test frequency of 100 MHz and supports a maximum DC current of 400 mA. Its maximum DC resistance is 0.3 Ω, with a tolerance of 25%. The device operates within a temperature range of -55°C to +125°C.
Feature Summary
- Designed for noise suppression on general signal lines
- Compact 0603 surface-mount footprint for space-constrained layouts
- Capable of handling 400 mA DC current without saturation
Applications
- General signal line filtering
- Noise suppression in electronic circuits
Procurement Notes
Verify the specific suffix 'BTA00' against official TDK documentation to confirm packaging details and compliance status. Ensure the selected variant matches the required impedance and current ratings for the target application. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm RoHS and Halogen-Free compliance requirements align with project specifications before finalizing procurement.
Selection Notes
Select this component when a 120 Ω impedance at 100 MHz is required for signal integrity management. The 400 mA current rating suits low-power signal lines rather than power delivery paths. The 0603 package size offers a balance between thermal performance and board space efficiency. Consider the -55°C to +125°C operating range for environmental suitability.
Part Context
This component belongs to the TDK MMZ series of ferrite chip beads, which are widely used for EMI suppression. The MMZ series covers various package sizes and impedance values to address different circuit requirements. The MMZ1608D121BTA00 specifically targets general signal lines, providing effective high-frequency noise attenuation while maintaining low DC resistance to minimize signal loss.
FAQ
