1206J0250821MCTE01

Overview

The Knowles Syfer 1206J0250821MCTE01 is a three-terminal feed-through multilayer ceramic capacitor designed for surface-mount applications. It features an 820 pF capacitance with a ±20% tolerance, rated for 25 VDC. The component utilizes C0G dielectric material and operates within a temperature range of -55°C to +125°C. Housed in a standard 1206 (3216 metric) package, it provides high-frequency noise suppression capabilities suitable for EMI filtering.

Feature Summary

• Three-terminal feed-through architecture for enhanced high-frequency noise attenuation
• C0G dielectric material ensuring stable capacitance characteristics across temperature variations
• Surface-mount design compatible with automated assembly processes

Applications

• High-frequency EMI filtering in sensitive electronic circuits
• Power supply line noise suppression
• Signal integrity protection in communication modules

Procurement Notes

Verify the specific suffix MCTE01 against official datasheets to confirm terminal configuration and termination materials. Ensure compatibility with PCB footprint requirements for three-terminal devices. Confirm RoHS compliance status through manufacturer documentation prior to integration into regulated assemblies.

Selection Notes

Select this component when superior high-frequency attenuation is required compared to standard two-terminal MLCCs. The three-terminal design offers lower parasitic inductance. Verify that the 25V rating and 820pF value align with circuit impedance and voltage constraints. Consider thermal management within the specified operating range.

Part Context

This part belongs to the Knowles Syfer feed-through capacitor series, which specializes in EMI suppression. These components integrate filtering functions directly into the capacitor structure, reducing board space usage. The 1206J prefix indicates the standard case size and voltage class within the product family.

Replacement Considerations

Direct substitutes must match the three-terminal feed-through topology and 1206 package dimensions. Verify identical capacitance, voltage rating, and dielectric type. Cross-reference with other manufacturers offering equivalent EMI filter capacitors if availability is constrained.
