Overview
The MPZ2012S300AT000 is a surface-mount ferrite bead from the TDK MPZ series, designed for noise suppression in signal and power lines. It features a 2012 metric (0805) package with dimensions of 2.00mm length and 1.25mm width. The component provides an impedance of 30 Ohms at 100 MHz and supports a maximum DC current rating of 6A. Its maximum DC resistance is 10 milliohms, ensuring low insertion loss. The device operates within a temperature range of -55°C to 125°C and is RoHS compliant.
Feature Summary
- High current handling capability suitable for power supply circuits
- Low DC resistance minimizes voltage drop in signal paths
- Compact chip form factor enables dense PCB layouts
Applications
- Automotive electronic systems
- Power supply circuit noise filtering
- Signal line interference suppression
Procurement Notes
Verify that the specific suffix 'AT000' matches the required tape-and-reel packaging configuration for automated assembly processes. Confirm that the 6A current rating aligns with the thermal management capabilities of the target application environment. Ensure compatibility with standard reflow soldering profiles defined for 2012 metric components.
Selection Notes
Select this component when high current capacity is required alongside moderate noise attenuation. The 30 Ohm impedance offers a balance between signal integrity preservation and EMI reduction. Consider the 2012 footprint constraints against available board space. Evaluate thermal dissipation requirements given the 6A continuous current rating.
Part Context
This ferrite bead belongs to the MPZ series, which is specifically engineered for commercial and automotive applications. The series utilizes multi-layer ceramic technology to achieve stable performance across wide temperature ranges. It serves as a passive filter component to suppress electromagnetic interference in compact electronic designs.
Replacement Considerations
The HF70ACC321611-T is listed as a manufacturer recommended substitute. Note that the replacement differs significantly in physical size (1206 vs 0805), current rating (1.5A vs 6A), and impedance (26 Ohms vs 30 Ohms). Verify mechanical clearance and electrical performance before substitution.
