1206J1000123MXTE07

Overview

The Knowles Syfer 1206J1000123MXTE07 is a feedthrough capacitor with a capacitance of 0.012 µF and a DC voltage rating of 100 VDC. It utilizes X7R dielectric material and offers a tolerance of ±20%. The component features a three-terminal SMD/SMT configuration in a 1206 (3216 metric) package, measuring 3.2 mm in length, 1.6 mm in width, and 1.1 mm in height. It operates within a temperature range of -55°C to +125°C.

Feature Summary

• Three-terminal EMI filter design for effective noise suppression
• Feedthrough architecture providing low impedance paths for high-frequency interference
• X7R dielectric stability across the specified operating temperature range

Applications

• High-frequency EMI filtering in compact electronic assemblies
• Signal line protection in data communication interfaces
• Power supply input filtering for sensitive circuitry

Procurement Notes

Verify the specific ordering suffix against official Knowles Syfer documentation to ensure correct termination and packaging specifications. Confirm that the three-terminal feedthrough form factor aligns with your PCB layout requirements. Cross-reference the 1206 footprint dimensions with your assembly tools. Ensure the X7R dielectric characteristics meet your circuit's thermal and electrical performance criteria before finalizing procurement.

Selection Notes

Select this component when a three-terminal feedthrough topology is required for superior high-frequency attenuation compared to standard two-terminal capacitors. The 1206 size allows for space-constrained designs while maintaining robust EMI performance. Consider the X7R dielectric properties for applications requiring stable capacitance over varying temperatures. Evaluate the 100V rating against peak circuit voltages to ensure adequate margin.

Part Context

This part belongs to the Knowles Syfer XT series of general type MLCCs. It is categorized under ceramic capacitors and specifically designed as an EMI filter. The manufacturer identifies it as a feedthrough capacitor, distinguishing it from standard decoupling or coupling capacitors within the broader multilayer ceramic capacitor product family.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Verify compatibility with alternative feedthrough capacitors by matching the 1206 footprint, 100V rating, 0.012 µF capacitance, and three-terminal structure.
