1206J2000103MJTE03

Overview

The Knowles Syfer 1206J2000103MJTE03 is a three-terminal feedthrough capacitor designed for surface mount technology. It features a 10 nF capacitance with a ±20% tolerance and a DC voltage rating of 200 V. The component utilizes X7R dielectric material, ensuring stable performance across a temperature range of -55°C to +125°C. Housed in a standard 1206 (3216 metric) package measuring 3.2 mm x 1.6 mm x 1.1 mm, it incorporates nickel barrier end terminations. This device functions as an EMI filter within the X2Y capacitor filter series.

Feature Summary

• Three-terminal architecture providing inherent common-mode noise suppression capabilities
• X2Y design integrates multiple filtering functions into a single compact footprint
• Nickel barrier termination structure enhances solderability and mechanical reliability

Applications

• High-frequency electromagnetic interference filtering in dense circuit boards
• Power supply line conditioning for sensitive electronic components
• Signal integrity protection in high-speed digital interfaces

Procurement Notes

Verify the complete part number including suffixes against manufacturer documentation to ensure correct termination and tolerance specifications. Confirm RoHS compliance status through official datasheets prior to integration. Cross-reference Mouser or DigiKey identifiers to validate sourcing channels and current availability constraints.

Selection Notes

Select this component when space-constrained designs require effective common-mode noise attenuation without additional discrete filters. The 1206 footprint offers a balance between parasitic inductance reduction and board area efficiency. Ensure operating voltages remain within the 200 VDC limit and temperatures stay within the specified industrial range for optimal longevity.

Part Context

This component belongs to the Knowles Syfer X2Y capacitor filter family, which combines series and shunt capacitances in a monolithic structure. The 1206J series specifically targets applications requiring robust EMI suppression in compact form factors. It serves as a specialized alternative to traditional multi-component LC filter networks.

Replacement Considerations

Direct substitutes include other 1206 package X2Y capacitors from Knowles Syfer with matching 10 nF capacitance and 200 V ratings. Verify terminal configuration and dielectric type compatibility before substitution.
