1206Y1000273MJTE07

Overview

The Knowles Syfer 1206Y1000273MJTE07 is a Class 1 multilayer ceramic capacitor (MLCC) designed for surface mount technology. It features an X7R dielectric material and offers a capacitance of 0.027 µF with a tolerance of ±20%. The component is rated for a DC voltage of 100V and operates within a temperature range of -55°C to +125°C. Housed in a standard 1206 (3216 metric) package, it utilizes a three-terminal architecture with nickel barrier and tin terminations. This configuration functions as an EMI filter, providing enhanced electromagnetic interference suppression capabilities compared to standard two-terminal designs.

Feature Summary

• Three-terminal architecture integrated into a compact 1206 footprint for effective EMI filtering
• Utilizes X7R dielectric material to maintain stable capacitance across wide temperature variations
• Features nickel barrier and tin termination plating for reliable solderability and corrosion resistance

Applications

• Electromagnetic interference (EMI) filtering in high-density circuit boards
• Power supply input and output stages requiring noise suppression
• Automotive electronics systems adhering to AEC-Q200 reliability standards

Procurement Notes

Verify the specific suffix codes against official manufacturer documentation to confirm terminal configuration and dielectric type. Ensure compatibility with automated pick-and-place equipment due to the three-terminal form factor. Cross-reference RoHS compliance status with current regulatory requirements before finalizing procurement orders.

Selection Notes

Select this component when board space is limited but superior EMI attenuation is required compared to standard MLCCs. The three-terminal design allows for lower parasitic inductance, making it suitable for high-frequency noise reduction. Confirm that the 100V rating meets the peak transient voltage requirements of the target application circuit.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, which emphasizes mechanical robustness for applications sensitive to board flexing. The 1206Y series specifically targets general-purpose and automotive markets, offering a balance between electrical performance and physical durability in standard SMD packages.

Replacement Considerations

Direct substitutes must match the 1206 footprint, 100V rating, 0.027µF value, and critically, the three-terminal EMI filter structure. Standard two-terminal capacitors are not functionally equivalent for noise suppression. Verify lead-free termination compatibility if replacing older inventory.
