1206J0250472MJTE07

Overview

The Knowles Syfer 1206J0250472MJTE07 is a high-reliability multilayer ceramic feed-through capacitor designed for surface-mount technology. It features a capacitance of 4700 pF with a DC voltage rating of 25 VDC and a tolerance of ±20%. The component utilizes C0G (NP0) dielectric material, ensuring stable performance across an operating temperature range of -55°C to +125°C. Housed in a standard 1206 (3216 metric) package, it integrates a three-terminal architecture with FlexiCap/Nickel Barrier construction to provide effective electromagnetic interference filtering.

Feature Summary

• Three-terminal feed-through architecture for enhanced EMI suppression
• FlexiCap and Nickel Barrier construction for reliability
• C0G (NP0) dielectric for stable capacitance characteristics
• Surface-mount design compatible with automated assembly

Applications

• High-frequency signal line filtering
• Power supply input/output decoupling
• EMI suppression in sensitive electronic circuits
• Automotive electronics requiring AEC-Q200 compliance

Procurement Notes

Verify the complete part number including suffixes to ensure correct termination and packaging specifications. Confirm RoHS compliance status and specific environmental certifications required for your application. Check manufacturer datasheets for detailed handling instructions and soldering profiles. Ensure compatibility with existing PCB footprint designs before procurement.

Selection Notes

Select this component when high-frequency noise attenuation is critical in low-voltage applications. The three-terminal design offers superior shielding compared to standard two-terminal capacitors. Consider the 1206 package size for space-constrained boards requiring robust EMI performance. 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 high-reliability MLCC family, specifically engineered for demanding environments. The 1206J series denotes a standard 1206 footprint with J-series voltage coding. As a feed-through capacitor, it differs from standard MLCCs by integrating ground planes within the structure for improved filtering efficiency.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Consult manufacturer catalogs for equivalent three-terminal feed-through capacitors with matching capacitance, voltage, and package dimensions.
