1806Y0500183MJTE07

Overview

The Knowles Syfer 1806Y0500183MJTE07 is a surface-mount multilayer ceramic feed-through capacitor designed for high-frequency noise suppression. It features an X7R dielectric with a capacitance of 0.018 µF and a DC voltage rating of 50 VDC. The component utilizes a three-terminal architecture within an 1806 (4516 metric) package, incorporating FlexiCap technology with nickel barrier terminations to enhance mechanical reliability. It operates effectively across a temperature range of -55°C to +125°C.

Feature Summary

• Three-terminal EMI filter architecture providing superior high-frequency noise attenuation compared to standard two-terminal capacitors.
• FlexiCap termination system with nickel barrier layers to mitigate stress-induced cracking during thermal cycling and board flexing.
• X7R dielectric material offering stable capacitance performance over a wide operating temperature range.

Applications

• High-speed digital signal line filtering in communication equipment
• Power supply input/output decoupling in sensitive analog circuits
• EMI suppression in automotive electronic control units

Procurement Notes

Verify the specific suffix JE07 against official datasheets to confirm terminal plating and RoHS compliance status. Ensure the ordering part number matches the exact capacitance tolerance and packaging format required for your assembly process. Cross-reference the manufacturer's latest revision history to confirm no design changes have occurred since the last procurement cycle.

Selection Notes

Select this component when high current handling and low impedance at high frequencies are critical. The three-terminal design offers better RF grounding than standard MLCCs. Verify that the 1806 footprint accommodates the specific height requirements and that the X7R characteristics align with the circuit's stability needs under varying thermal conditions.

Part Context

This component belongs to the Knowles Syfer Y-series, which specializes in high-reliability EMI filter capacitors. The series integrates advanced termination technologies to address common failure modes in harsh environments. It serves as a specialized solution for applications requiring robust noise suppression where standard capacitors may fail due to mechanical stress or insufficient high-frequency performance.

Replacement Considerations

Direct substitutes must match the 1806 footprint, 50V rating, 0.018µF value, and three-terminal structure. Verify compatibility of FlexiCap-style terminations if mechanical shock resistance is required. Standard two-terminal X7R capacitors are not functionally equivalent due to inferior EMI filtering performance.
