1206J0500183MJTE07

Overview

The Knowles Syfer 1206J0500183MJTE07 is a three-terminal surface-mount EMI filter capacitor designed for high-frequency noise suppression. It features a capacitance of 0.018 µF with a voltage rating of 50 VDC and a tolerance of ±20%. The component utilizes X7R 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 nickel barrier termination system to enhance solderability and mechanical reliability while providing effective electromagnetic interference filtering in compact circuit layouts.

Feature Summary

• Three-terminal architecture provides enhanced electromagnetic interference filtering compared to standard two-terminal capacitors
• Nickel barrier termination system improves solder joint reliability and resistance to corrosion
• X7R dielectric material maintains consistent capacitance characteristics over a wide industrial temperature range

Applications

• High-frequency noise suppression in sensitive analog signal lines
• Power supply input filtering for integrated circuits requiring clean DC rails
• Electromagnetic compatibility enhancement in compact consumer electronic devices

Procurement Notes

Verify the specific suffix codes against official manufacturer documentation to confirm terminal composition and dielectric specifications. Ensure that the selected variant matches the required thermal endurance and current handling capabilities for the target application environment. Cross-reference part numbers with authorized distributors to avoid counterfeit components and confirm compliance with relevant environmental directives.

Selection Notes

Select this component when space constraints require a 1206 footprint but superior EMI attenuation is necessary. The three-terminal design offers better high-frequency performance than parallel two-terminal configurations. Evaluate the impedance characteristics at the target noise frequency to ensure adequate attenuation. Confirm that the 50V rating exceeds the maximum circuit voltage including transients to prevent dielectric breakdown.
