1206J1000822MJTE07

Overview

The Knowles Syfer 1206J1000822MJTE07 is a surface-mount feed-through multilayer ceramic capacitor designed for EMI filtering. It features an 8.2 nF capacitance with a ±20% tolerance, rated for 100 VDC. The component utilizes X7R (2R1) dielectric material and incorporates a three-terminal architecture to provide enhanced high-frequency noise suppression. It is housed in a standard 1206 (3216 metric) package with nickel barrier and 100% tin terminations.

Feature Summary

• Three-terminal feed-through structure for superior high-frequency EMI attenuation
• X7R dielectric composition ensuring stable performance across operating temperatures
• Nickel barrier and 100% tin termination system for reliable solderability

Applications

• High-frequency electromagnetic interference filtering in electronic circuits
• Power supply line noise suppression
• Signal integrity protection in sensitive digital systems

Procurement Notes

Verify the specific suffix 'MJTE07' to confirm the three-terminal feed-through configuration, as standard MLCCs share similar base codes but lack this filtering architecture. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure PCB layout accommodates the distinct terminal arrangement required for effective feed-through operation.

Selection Notes

Select this component when standard two-terminal capacitors fail to meet EMI suppression requirements at high frequencies. The three-terminal design offers lower parasitic inductance compared to conventional SMD capacitors. Evaluate the 100V rating against peak circuit voltages to ensure adequate margin. Consider the physical footprint compatibility with existing 1206 land patterns during the design phase.

Part Context

This part belongs to the Knowles Syfer family of specialized EMI filter capacitors. Unlike general-purpose Class 2 MLCCs, this series integrates a grounded center terminal to shunt noise currents directly to ground. The 1206 form factor allows for compact board designs while maintaining robust filtering capabilities in space-constrained applications.

Replacement Considerations

Direct substitutes must match the three-terminal feed-through topology. Standard 1206 MLCCs are not functionally equivalent due to differing impedance characteristics. Verify alternative part numbers from the same manufacturer that specify identical terminal configurations and electrical ratings.
