Overview
The MPZ1005D330ETD25 is a surface-mount ferrite bead from the TDK MPZ-E series, designed for power line applications in automotive environments. It features a 0402 (1005 metric) package with dimensions of 1.0 mm length, 0.5 mm width, and 0.5 mm height. The component provides an impedance of 33 ohms at 100 MHz with a tolerance of 25%. It supports a maximum DC current of 0.80 A and has a maximum DC resistance of 180 milliohms. Certified to AEC-Q200 standards, it operates within a temperature range of -55°C to +125°C.
Feature Summary
- AEC-Q200 qualified for automotive reliability requirements
- Optimized for high-current power line noise suppression
- Compact 0402 footprint for space-constrained designs
Applications
- Automotive electronic power distribution circuits
- Noise suppression on DC power supply lines
- Embedded system power rail filtering
Procurement Notes
Verify the specific suffix ETD25 against official TDK documentation to confirm tape-and-reel packaging specifications. Ensure the procurement channel sources genuine components matching the MPZ-E series designation. Cross-reference the AEC-Q200 certification status directly with manufacturer records to validate automotive grade compliance before integration into production.
Selection Notes
Select this component when designing power rails requiring moderate impedance at 100 MHz with high current handling capabilities up to 0.80 A. The low DC resistance minimizes voltage drop across the filter. Consider the 0402 package size for board real estate constraints. Verify thermal management requirements given the operating temperature range extends to 125°C under load conditions.
Part Context
This part belongs to the MPZ-E series, which specializes in ferrite beads for automotive power lines. Unlike signal line beads, these are engineered to handle higher DC currents while maintaining effective noise attenuation. The MPZ1005 form factor represents the smallest standard size in this automotive-grade lineup, balancing performance with miniaturization needs.
Replacement Considerations
Consult TDK's official substitution guide for equivalent impedance and current ratings. Verify that any alternative maintains AEC-Q200 certification if automotive application is required. Ensure physical dimensions match the 0402 footprint to avoid rework.
