1206Y0250103MJTE07

Overview

The Knowles Syfer 1206Y0250103MJTE07 is a three-terminal EMI filter capacitor housed in a 1206 (3216 metric) surface-mount package. It features an X7R dielectric with a nominal capacitance of 10 nF and a voltage rating of 25 VDC. The component utilizes FlexiCap technology with nickel barrier end terminals to enhance mechanical reliability. Designed for high-frequency noise suppression, it serves as a feed-through capacitor in sensitive electronic circuits.

Feature Summary

• Three-terminal architecture providing superior high-frequency EMI filtering compared to standard two-terminal capacitors
• FlexiCap flexible end termination design integrated with nickel barriers to absorb mechanical stress and prevent solder joint cracking
• X7R ceramic dielectric offering stable capacitance performance across a wide operating temperature range

Applications

• High-reliability aerospace and defense systems requiring robust EMI suppression
• Sensitive communication equipment where signal integrity must be maintained against electromagnetic interference
• Automotive electronics subject to rigorous mechanical vibration and thermal cycling

Procurement Notes

Verify the specific suffix codes on official datasheets to confirm terminal composition and tolerance levels. Ensure compatibility with PCB footprint requirements for three-terminal components. Confirm RoHS compliance status through manufacturer documentation prior to integration into regulated assemblies.

Selection Notes

Select this component when standard MLCCs fail under mechanical stress or require enhanced high-frequency attenuation. The three-terminal structure necessitates specific layout considerations for optimal grounding. Evaluate thermal stability requirements against the X7R characteristics to ensure performance consistency across the intended operational environment.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, which specializes in high-reliability multilayer ceramic capacitors. The series addresses common failure modes in harsh environments by combining flexible terminations with rigid internal structures. It targets applications demanding extended lifecycle and resistance to board flexing.

Replacement Considerations

Direct substitutes include other 1206 three-terminal EMI filters from the same manufacturer family with matching capacitance and voltage ratings. Verify that alternative parts maintain the FlexiCap termination style if mechanical durability is critical. Cross-reference pin configurations to ensure proper electrical connectivity.
