1206J2000183MJTE07

Overview

The Knowles Syfer 1206J2000183MJTE07 is a three-terminal surface-mount EMI filter capacitor in a 1206 (3216 metric) package. It features an X7R dielectric with a capacitance of 0.018 µF and a voltage rating of 200 VDC. The component utilizes a nickel barrier electrode structure and tin terminations, designed for high-frequency noise suppression in compact electronic assemblies.

Feature Summary

• Three-terminal architecture providing enhanced electromagnetic interference filtering compared to standard two-terminal capacitors
• Nickel barrier internal electrode construction ensuring robust performance under thermal stress
• X7R temperature stable ceramic dielectric suitable for general-purpose applications across wide operating ranges

Applications

• High-frequency noise suppression in power supply input stages
• Signal line filtering in communication equipment
• Electromagnetic compatibility enhancement in compact consumer electronics

Procurement Notes

Verify the specific suffix configuration against official datasheets to confirm terminal material and barrier layer specifications. Ensure the selected variant matches the required voltage derating and capacitance tolerance for the target circuit design before finalizing procurement orders.

Selection Notes

Select this component when space-constrained designs require superior high-frequency attenuation than standard MLCCs provide. The three-terminal layout offers lower parasitic inductance, making it ideal for decoupling sensitive digital or RF circuits where signal integrity is critical.

Part Context

This part belongs to the Knowles Syfer XT series of feed-through capacitors. These components are engineered specifically for EMI/RFI suppression in small form factors.
