1206J0500823MXTE01

Overview

The Knowles Syfer 1206J0500823MXTE01 is a three-terminal feedthrough capacitor designed for surface mount applications. It features an X7R dielectric with a capacitance of 82 nF and a DC voltage rating of 50 VDC. The component operates within a temperature range of -55°C to +125°C and maintains a tolerance of ±20%. Housed in a 1206 (3216 metric) package, it utilizes a nickel barrier and 100% tin termination system. This Class 2 MLCC serves as an integrated EMI filter, providing superior noise suppression capabilities compared to standard two-terminal capacitors.

Feature Summary

• Three-terminal architecture provides enhanced electromagnetic interference filtering performance
• Integrated surface mount design eliminates the need for discrete filter components
• Utilizes X7R ceramic dielectric for stable capacitance characteristics across operating temperatures

Applications

• High-frequency noise suppression in sensitive electronic circuits
• Power line filtering for DC power distribution networks
• Signal integrity protection in communication interfaces

Procurement Notes

Verify the specific termination material composition and lead-free status against current RoHS directives before integration. Confirm that the 1206 footprint dimensions align precisely with the target PCB layout constraints. Ensure thermal management strategies account for the maximum operating temperature limits specified in the official datasheet to maintain long-term reliability under load conditions.

Selection Notes

Select this component when space-constrained designs require effective common-mode or differential-mode noise attenuation without adding external filter stages. The three-terminal configuration offers lower parasitic inductance than standard MLCCs, making it suitable for high-speed digital or RF applications where signal purity is critical. Evaluate the impedance characteristics at the target frequency of operation to ensure adequate filtering effectiveness.

Part Context

This part belongs to the Knowles Syfer feedthrough capacitor family, which integrates capacitor functionality into a single surface-mount package. These components are engineered to replace traditional discrete LC filters, reducing board space and assembly complexity. The series is recognized for its robust construction and consistent electrical performance in demanding industrial and commercial environments.

Replacement Considerations

Direct substitutes include other 1206 three-terminal EMI filters from manufacturers such as TDK (LMK series) or Murata (GJM series), provided they match the 82 nF capacitance, 50 VDC rating, and X7R dielectric type. Verify terminal compatibility and mounting orientation differences before substitution.
