1206J0250562MJTE07

Overview

The Knowles Syfer 1206J0250562MJTE07 is a surface-mount feed-through capacitor designed for high-frequency noise suppression. It features a 1206 (3216 metric) case size with a capacitance of 5600 pF and a DC voltage rating of 25 V. The component utilizes C0G/NP0 dielectric material, ensuring stable performance across a temperature range of -55°C to +125°C. It incorporates a three-terminal architecture with nickel barrier and tin termination, providing effective EMI filtering capabilities.

Feature Summary

• Three-terminal feed-through architecture for enhanced electromagnetic interference suppression
• C0G/NP0 dielectric material ensures minimal capacitance variation over temperature and voltage
• Nickel barrier and 100% tin terminations provide reliable solderability and corrosion resistance

Applications

• High-frequency signal line filtering in communication equipment
• Power supply input/output decoupling in sensitive digital circuits
• EMI suppression in automotive electronic control units
• Noise reduction in RF amplifier stages

Procurement Notes

Verify the complete part number including the suffix to confirm the specific termination and packaging configuration. Ensure compatibility with standard reflow soldering profiles for three-terminal MLCCs. Confirm that the application circuit design accounts for the parasitic inductance inherent in feed-through structures. Cross-reference the manufacturer datasheet for handling instructions regarding moisture sensitivity and mechanical stress limits during assembly.

Selection Notes

Select this component when superior high-frequency attenuation is required compared to standard two-terminal capacitors. The three-terminal design offers lower effective series inductance, making it suitable for applications above 100 MHz. Consider the physical footprint constraints of the 1206 package and the need for ground plane connectivity on both sides of the component. Evaluate the trade-off between insertion loss and signal integrity for the specific frequency band of interest.

Part Context

This component belongs to the Knowles Syfer FlexiCap or general high-reliability MLCC family, characterized by robust construction for demanding environments. The 1206J prefix indicates a 1206 case size with J tolerance coding, while the Y suffix typically denotes the three-terminal filter variant within the product line. These parts are engineered for industrial and automotive sectors requiring consistent performance under thermal cycling and vibration.

Replacement Considerations

Direct substitutes include other 1206 three-terminal feed-through capacitors from Knowles Syfer with matching capacitance and voltage ratings. Verify equivalent electrical parameters such as impedance characteristics and current handling capabilities before substitution.
