1206Y0250563MJTE07

Overview

The Knowles Syfer 1206Y0250563MJTE07 is a high-reliability multilayer ceramic capacitor (MLCC) designed for surface mount technology. It features an X7R dielectric material with a capacitance of 0.056 µF and a DC voltage rating of 25 VDC. The component utilizes a 1206 (3216 metric) package size and offers a tolerance of ±20%. It is engineered as a three-terminal EMI filter with FlexiCap/Nickel Barrier construction, providing enhanced mechanical stability and electromagnetic interference suppression capabilities.

Feature Summary

• Three-terminal architecture functions as an integrated EMI filter for noise suppression
• FlexiCap technology with nickel barrier end termination improves board flexibility resistance
• X7R dielectric provides stable capacitance characteristics across the operating temperature range

Applications

• High-frequency signal line filtering in sensitive electronic circuits
• Power supply input stages requiring common-mode noise reduction
• Automotive electronics systems demanding high reliability and vibration resistance
• Industrial control boards subject to electromagnetic interference environments

Procurement Notes

Verify the complete part number including the suffix to ensure correct terminal configuration and termination material specifications. Confirm RoHS compliance status and environmental declarations prior to integration. Check manufacturer datasheets for specific handling requirements related to the nickel barrier structure. Ensure design compatibility with the three-terminal footprint layout to maintain intended filtering performance.

Selection Notes

Select this component when simultaneous decoupling and EMI filtration are required in a single surface-mount package. The three-terminal design differs from standard two-terminal capacitors by providing a grounded shield between terminals. Consider the FlexiCap feature if the application involves mechanical stress or board flexing. Verify that the 25V rating meets the circuit's peak voltage requirements under all operating conditions.

Part Context

This component belongs to the Knowles Syfer FlexiCap series, which specializes in high-reliability MLCCs for demanding applications. The 1206Y prefix indicates the 1206 case size within the Syfer portfolio. The product line targets industries requiring robust performance against thermal cycling and mechanical shock, distinguishing it from general-purpose ceramic capacitors through its specialized internal electrode structure.

Replacement Considerations

Direct substitutes must match the three-terminal EMI filter topology and 1206 package dimensions. Standard two-terminal capacitors cannot replicate the shielding function without redesigning the PCB layout. Verify that alternative parts support the same X7R dielectric class and voltage rating to maintain circuit stability.
