1206J2000220MCTE03

Overview

The Knowles Syfer 1206J2000220MCTE03 is a three-terminal feed-through capacitor in a 1206 (3216 metric) surface-mount package. It features a capacitance of 22 pF with a tolerance of ±20% and a DC voltage rating of 200 VDC. The component utilizes C0G/NP0 dielectric technology for stable performance. It incorporates a nickel barrier and 100% tin termination system. This X2Y architecture provides integrated EMI filtering capabilities within the standard footprint.

Feature Summary

• Integrates X2Y three-terminal architecture for simultaneous common-mode and differential-mode noise suppression
• Utilizes C0G/NP0 dielectric material to ensure high stability and low loss across operating conditions
• Employs nickel barrier and 100% tin terminations for reliable solderability and corrosion resistance

Applications

• High-frequency signal line filtering in communication equipment
• Power supply decoupling in sensitive analog circuits
• EMI suppression in automotive electronic control units

Procurement Notes

Verify the specific suffix 'E03' against the manufacturer's current datasheet to confirm terminal configuration and packaging details. Ensure compatibility with PCB pad layouts designed for three-terminal feed-through components. Confirm RoHS compliance status through official documentation prior to integration into regulated assemblies.

Selection Notes

Select this component when space-constrained designs require combined filtering and decoupling functions. The 1206 footprint allows for density optimization compared to discrete filter networks. Verify that the 200V rating exceeds peak circuit voltages and that the 22pF value aligns with target impedance requirements at the frequency of interest.

Part Context

This part belongs to the Knowles Syfer X2Y family, which merges two capacitors and one inductor into a single monolithic structure. The series offers enhanced noise attenuation compared to standard two-terminal MLCCs. The 1206 size represents a balance between parasitic inductance reduction and board space efficiency.

Replacement Considerations

Direct substitutes must match the three-terminal feed-through topology and X2Y internal configuration. Standard two-terminal capacitors cannot replicate the combined filtering action. Verify equivalent capacitance, voltage rating, and physical dimensions before substitution.
