1806J0500124MJTE07

Overview

The Knowles Syfer 1806J0500124MJTE07 is a surface-mount multilayer ceramic capacitor (MLCC) designed for EMI filtering applications. It features an 1806 case size with a capacitance of 120 nF and a voltage rating of 50 VDC. The component utilizes X7R dielectric material, offering a tolerance of ±20%. It employs a three-terminal architecture with nickel barrier and 100% tin terminations to enhance electromagnetic interference suppression in high-frequency circuits.

Feature Summary

• Three-terminal structure for effective common-mode noise attenuation
• Nickel barrier termination system ensuring robust solderability
• X7R dielectric composition providing stable performance across temperature ranges

Applications

• High-speed digital signal line filtering
• Power supply input/output decoupling
• EMI suppression in communication equipment

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm terminal configuration and packaging details. Ensure compatibility with automated pick-and-place equipment regarding the 1806 footprint dimensions. Cross-reference RoHS compliance status with latest regulatory updates before final procurement approval.

Selection Notes

Select this component when high capacitance density is required within a standard 1806 footprint for EMI control. The three-terminal design offers superior filtering compared to two-terminal alternatives. Consider thermal management requirements as X7R characteristics vary with applied DC bias voltage during circuit simulation.

Part Context

This part belongs to the Knowles Syfer general-purpose MLCC family, specifically engineered for surface-mount technology. It integrates into broader passive component strategies for noise reduction in compact electronic assemblies. The product line emphasizes reliability and consistent electrical performance for industrial and commercial applications.

Replacement Considerations

Direct substitutes must match the 1806 case size, 120 nF capacitance, 50 VDC rating, and three-terminal EMI filter topology. Verify that alternative components maintain identical nickel barrier termination specifications and X7R dielectric class to ensure functional equivalence.
