1206Y0250183MJTE07

Overview

The Knowles Syfer 1206Y0250183MJTE07 is a multilayer ceramic capacitor (MLCC) designed for surface mount technology. It features a capacitance of 18 nF with a tolerance of ±20% and a rated DC voltage of 25V. The dielectric material is X7R, providing stable performance across a temperature range of -55°C to +125°C. The component utilizes the FlexiCap™ technology with soft terminals to enhance mechanical reliability. It is housed in a standard 1206 (3216 metric) package with dimensions of 3.20mm x 1.60mm x 1.60mm maximum height.

Feature Summary

• FlexiCap™ soft terminal technology reduces stress on the capacitor body during board flexing
• X7R dielectric provides consistent capacitance characteristics over a wide operating temperature range
• Three-terminal EMI filter configuration offers enhanced noise suppression capabilities

Applications

• Automotive electronics requiring AEC-Q200 qualification
• Boardflex sensitive circuit designs
• EMI filtering in high-reliability applications

Procurement Notes

Verify the specific suffix 'MJTE07' against official Knowles Syfer documentation to confirm the three-terminal EMI filter configuration and nickel barrier construction. Standard two-terminal variants may share similar base part numbers but lack the filtering functionality. Ensure compatibility with automated pick-and-place equipment due to the specific terminal structure.

Selection Notes

Select this component when board flex resistance is critical for maintaining capacitor integrity in automotive or industrial environments. The three-terminal design is necessary for effective common-mode noise attenuation compared to standard two-terminal capacitors. Confirm that the 25V rating aligns with the circuit's peak voltage requirements and that the X7R temperature coefficient meets the operational thermal profile.

Part Context

This part belongs to the Knowles Syfer 1206Y series, which specializes in high-reliability MLCCs. The series incorporates proprietary FlexiCap™ technology to address mechanical failures caused by substrate warping. The 1206 form factor balances capacitance density with robustness, making it suitable for space-constrained yet mechanically demanding applications.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Cross-reference with other Knowles Syfer 1206Y series components only if they explicitly match the three-terminal EMI filter specification and FlexiCap™ terminal construction.
