1206J0500102MJTE03

Overview

The Knowles Syfer 1206J0500102MJTE03 is a surface-mount feedthrough capacitor designed for EMI suppression. It features a capacitance of 1000 pF with a ±20% tolerance and a DC voltage rating of 50 VDC. The component utilizes an X7R dielectric material, ensuring stability across a wide operating temperature range from -55°C to +125°C. Housed in a standard 1206 (3216 metric) package, it measures 3.2 mm in length, 1.6 mm in width, and 1.6 mm in height. This three-terminal device is part of the FlexiCap™ series and is supplied in reel packaging.

Feature Summary

• Three-terminal feedthrough architecture providing integrated EMI filtering capabilities within a compact surface-mount footprint.

Applications

• High-frequency signal line noise suppression
• Power distribution network decoupling
• EMI/RFI interference mitigation in sensitive electronic circuits

Procurement Notes

Verify the specific suffix 'E03' against official datasheets to confirm the exact packaging configuration and terminal plating specifications. Ensure compatibility with automated pick-and-place equipment regarding the 1206 package dimensions. Confirm RoHS compliance status through current manufacturer documentation before integration into regulated assemblies.

Selection Notes

Select this component when space-constrained designs require effective common-mode noise attenuation without adding discrete filter components. The X7R dielectric offers a favorable balance between capacitance density and temperature stability for general-purpose applications. Evaluate the 50V rating against peak transient voltages to ensure adequate margin during operation.
