1206Y2000103MJTE03

Overview

The Knowles Syfer 1206Y2000103MJTE03 is a surface-mount feedthrough capacitor designed for high-frequency noise suppression. It features a 1206 (3216 metric) package with three terminals and X7R dielectric characteristics. The component provides a capacitance of 10 nF with a tolerance of ±20% and a DC voltage rating of 20 V. It operates within a temperature range of -55°C to +125°C.

Feature Summary

• Integrates three-terminal feedthrough architecture for superior high-frequency electromagnetic interference filtering.

Applications

• High-speed digital signal line protection
• Power supply input/output decoupling
• RF circuit noise suppression

Procurement Notes

Verify the specific suffix 'MJTE03' against official Knowles Syfer documentation to confirm terminal plating and packaging details. Ensure the selected variant matches the required 20V rating and 1206 footprint for your design. Cross-reference the Mouser number 843-1206Y2000103MJTE03 with manufacturer datasheets to validate availability and compliance status before finalizing procurement.

Selection Notes

Select this component when compact size and effective high-frequency attenuation are required in space-constrained designs. The X7R dielectric offers stable capacitance over temperature, suitable for general-purpose filtering. Verify that the 20V rating meets the circuit's maximum operating voltage and consider the thermal environment to ensure performance remains within specifications during operation.

Part Context

This part belongs to the Knowles Syfer X2Y capacitor filter series, which utilizes a unique internal electrode structure to provide common-mode and differential-mode noise suppression simultaneously. The 1206 package allows for standard SMT assembly processes, integrating filtering capabilities directly into the PCB layout without requiring additional discrete components.

Replacement Considerations

Consult official substitution guides for equivalent X2Y feedthrough capacitors with matching 10nF capacitance, 20V rating, and 1206 dimensions. Verify electrical parameters and physical footprint compatibility before replacing.
