1206J2000103MXTE03

Overview

The Knowles Syfer 1206J2000103MXTE03 is a surface-mount feedthrough capacitor in a 1206 (3216 metric) package. It features a capacitance of 10 nF with a ±20% tolerance and a DC voltage rating of 200 VDC. The component utilizes X7R dielectric material and includes an integrated 50 mA fuse function for circuit protection. Termination consists of nickel barrier plating with 100% tin, ensuring compatibility with standard SMD/SMT assembly processes.

Feature Summary

• Integrates X2Y filter topology within a single compact surface-mount component to reduce board space and simplify design.
• Incorporates a built-in 50 mA fuse element to provide overcurrent protection alongside signal filtering capabilities.
• Utilizes proprietary FlexiCap termination technology to enhance mechanical reliability against board bending and thermal cycling stress.

Applications

• High-density electronic assemblies requiring combined EMI suppression and overcurrent protection
• Signal conditioning circuits in automotive or industrial environments subject to mechanical vibration
• Power distribution lines where compact footprint and dual-functionality are critical

Procurement Notes

Verify the specific suffix MXTE03 against official Knowles Syfer documentation to confirm the presence of the nickel barrier/100% tin termination and the exact fuse current rating. Ensure the selected variant matches the required X7R temperature characteristics and 200V DC rating for the target application environment.

Selection Notes

Select this component when both electromagnetic interference filtering and circuit fusing are required in a limited space. The 1206 package offers a balance between current handling and size. Confirm that the 50 mA fuse threshold aligns with the protected circuit's maximum operating current to prevent nuisance blowing during normal operation.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, which employs flexible termination materials to improve durability under mechanical stress. The 1206J prefix indicates a 1206 case size with specific voltage and capacitance coding conventions used by the manufacturer for their multilayer ceramic feedthrough capacitors.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Verify pinout compatibility and electrical ratings before considering any alternative components from other manufacturers.

FAQ

What is the primary function of the MXTE03 suffix in this model?

The suffix denotes specific termination and packaging details, including nickel barrier plating with 100% tin finish and the specific reel/tray configuration as defined by Knowles Syfer.

How does the integrated fuse feature benefit the circuit design?

It provides overcurrent protection directly within the filter component, eliminating the need for a separate fuse and reducing the overall component count and board area.
