78279225101

Overview

The Würth Elektronik 78279225101 is a multilayer chip ferrite bead from the WE-MPSA series, designed for surface-mount assembly. It features a 3312 (8530 metric) package with dimensions of 8.5 mm length, 3.0 mm width, and 2.28 mm height. The component provides an impedance of 100 Ω at 100 MHz and exhibits a maximum impedance of 1200 MHz. It supports a DC current rating of 10 A and has a low DC resistance of 4 mΩ. Qualified under AEC-Q200 standards, it operates within a temperature range of -55°C to +125°C.

Feature Summary

High current handling capability suitable for power line filtering applications
Automotive qualification compliant with AEC-Q200 reliability standards
Multilayer construction enabling compact surface-mount integration

Applications

EMI suppression in automotive electronic systems
Power line filtering for high-current circuits
Signal integrity protection in industrial equipment

Procurement Notes

Verify the specific manufacturer part number against official Wurth Elektronik documentation to ensure authenticity. Confirm that the AEC-Q200 qualification status matches project requirements. Check datasheet specifications for impedance tolerance and current ratings prior to final selection. Ensure compliance with RoHS and REACH directives as stated in official product literature.

Selection Notes

Select this component when high DC current capacity is required alongside effective high-frequency noise attenuation. The 10 A rating distinguishes it from standard signal-line ferrites. Consider the 3312 package size for board space constraints. Verify thermal performance within the specified -55°C to +125°C operating range for the intended environment.

Part Context

This component belongs to the WE-MPSA series of multilayer chip ferrite beads. Unlike snap-on rings, this is a solid-state SMD device offering consistent electrical characteristics without air gaps. It serves as a passive EMI suppression element integrated directly into PCB traces.
