1206J0250223MXTE07

Overview

The Knowles Syfer 1206J0250223MXTE07 is a Class 2 multilayer ceramic capacitor (MLCC) designed for surface-mount technology. It features an X7R dielectric material providing stable capacitance across a temperature range of -55°C to +125°C. The component has a nominal capacitance of 22 nF with a tolerance of ±20% and a DC voltage rating of 25 VDC. It utilizes a 1206 (3216 metric) package size measuring 3.2 mm in length, 1.6 mm in width, and 1.6 mm in height. This specific variant incorporates a three-terminal architecture with a nickel barrier and 100% tin termination, functioning as an EMI filter.

Feature Summary

• Three-terminal EMI filter architecture utilizing a nickel barrier and 100% tin termination for enhanced signal integrity
• X7R dielectric composition ensures consistent electrical performance within the specified operating temperature range
• High-reliability construction suitable for demanding electronic environments requiring stable capacitance

Applications

• Electromagnetic interference filtering in high-frequency circuits
• Power supply decoupling applications requiring stable capacitance

Procurement Notes

Verify the exact part number against official manufacturer documentation to confirm the three-terminal EMI filter configuration. Ensure compatibility with PCB footprints designed for 1206 three-terminal components. Confirm RoHS compliance status through current datasheets. Validate that the nickel barrier termination meets soldering requirements for the intended assembly process.

Selection Notes

Select this component when EMI suppression is required alongside standard capacitance functions in a compact footprint. The three-terminal design offers superior high-frequency performance compared to standard two-terminal MLCCs. Consider the 25V rating and 22nF value relative to circuit requirements. Verify thermal stability needs align with the X7R characteristic for the operational environment.
