1206J0500184MJTE07

Overview

The Knowles Syfer 1206J0500184MJTE07 is a three-terminal surface-mount EMI filter capacitor housed in a 1206 (3216 metric) package. It features an X7R dielectric with a capacitance of 0.18 µF and a tolerance of ±20%. The component is rated for a DC voltage of 50V and operates within a temperature range of -55°C to +125°C. It utilizes a nickel barrier electrode structure with 100% tin terminations, designed for high-reliability applications requiring effective electromagnetic interference suppression.

Feature Summary

• Three-terminal architecture providing enhanced electromagnetic interference filtering performance compared to standard two-terminal capacitors
• Nickel barrier electrode construction ensuring robust mechanical integrity and reliable solderability
• X7R dielectric material offering stable capacitance characteristics across the specified operating temperature range

Applications

• Electromagnetic interference filtering in sensitive electronic circuits
• Power supply input and output stages for noise suppression
• Signal line protection in communication equipment

Procurement Notes

Verify the complete part number including suffixes against official manufacturer documentation to ensure correct termination and dielectric specifications. Confirm RoHS compliance status through current datasheets as regulatory requirements may evolve. Cross-reference with authorized distributor catalogs to validate availability and authenticity before procurement.

Selection Notes

Select this component when board space constraints require a 1206 footprint but superior EMI attenuation is needed. The three-terminal design offers better high-frequency performance than parallel two-terminal configurations. Ensure the 50V rating exceeds the maximum circuit voltage and consider the X7R temperature coefficient for thermal stability requirements.

Part Context

This component belongs to the Knowles Syfer high-reliability MLCC series, specifically engineered for demanding environments. The 1206J series denotes a 1206 case size with specific voltage and dielectric characteristics. These filters are widely used in industrial, automotive, and telecommunications sectors where signal integrity and noise immunity are critical.

Replacement Considerations

Direct substitutes must match the 1206 footprint, 50V rating, 0.18 µF capacitance, X7R dielectric, and three-terminal EMI filter configuration. Verify that alternative parts maintain compatible nickel barrier terminations and meet the same AEC-Q200 or equivalent reliability standards if required by the application.
