1806J0500682MJTE07

Overview

The Knowles Syfer 1806J0500682MJTE07 is a surface-mount feed-through capacitor designed for high-frequency noise suppression. It features a capacitance of 6800 pF with a ±20% tolerance, rated for 50 VDC. The component utilizes X7R dielectric material and operates within a temperature range of -55°C to +125°C. Housed in an 1806 (4516 metric) package, it integrates a center pin structure to provide low-inductance grounding paths. This design effectively attenuates electromagnetic interference in compact circuit layouts.

Feature Summary

• Integrates a center pin configuration to establish a direct ground connection, minimizing parasitic inductance for superior high-frequency performance.
• Utilizes X7R ceramic dielectric to maintain stable capacitance characteristics across the specified operating temperature range.
• Employs a three-terminal architecture to separate input and output signal paths from the ground plane, enhancing isolation.

Applications

• High-speed digital signal line filtering
• Power supply input/output decoupling
• RF circuit noise suppression

Procurement Notes

Verify the specific suffix 'E07' against the manufacturer's latest datasheet to confirm terminal plating and reel specifications. Ensure the selected variant matches the required current rating and physical footprint constraints for the target PCB layout. Cross-reference the RoHS compliance status with current regulatory requirements before finalizing procurement orders.

Selection Notes

Select this component when low parasitic inductance is critical for EMI reduction in space-constrained designs. The 1806 package offers a balance between current handling capability and board area efficiency. Consider the X7R temperature coefficient if the application environment experiences significant thermal fluctuations, ensuring capacitance stability under varying conditions.

Part Context

This part belongs to the Knowles Syfer feed-through capacitor series, which specializes in three-terminal MLCC technology. These components are engineered to replace traditional two-terminal capacitors in applications requiring superior high-frequency attenuation. The series supports various voltage ratings and capacitance values within standardized industrial packages.

Replacement Considerations

Direct substitutes must match the 1806 footprint, 6800 pF capacitance, 50V rating, and three-terminal feed-through structure. Verify that alternative parts offer comparable insertion loss characteristics and center pin current ratings to ensure equivalent circuit performance.
