1806Y1000333MJTE07

Overview

The Knowles Syfer 1806Y1000333MJTE07 is a three-terminal feed-through capacitor designed for high-frequency noise suppression. It features a capacitance of 0.033 µF with a ±20% tolerance and a DC voltage rating of 100 V. The component utilizes C0G/NP0 dielectric material, ensuring stable performance across an operating temperature range of -55°C to +125°C. Housed in an 1806 (4516 metric) surface-mount package, it includes a center pin termination for direct board mounting.

Feature Summary

• Three-terminal EMI filter architecture providing superior high-frequency noise attenuation compared to standard two-terminal capacitors.
• Center pin termination design allows for low-inductance grounding directly through the PCB substrate.
• C0G/NP0 dielectric composition maintains consistent capacitance values under varying temperature and bias conditions.

Applications

• High-speed digital signal line filtering
• RF circuit power supply decoupling
• EMI suppression in sensitive analog circuits

Procurement Notes

Verify the specific suffix 'J' indicates the required tolerance level and terminal configuration against the official datasheet. Confirm that the 1806 footprint matches the PCB layout constraints. Ensure the 100V rating meets the circuit's peak voltage requirements. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when low parasitic inductance is critical for noise reduction. The three-terminal structure offers better high-frequency performance than standard MLCCs. Consider the physical size relative to available board space. Verify compatibility with reflow soldering profiles suitable for feed-through capacitor terminations.

Part Context

This part belongs to the Knowles Syfer FlexiCap or specialized EMI filter series, distinguished by its three-terminal construction. Unlike standard multilayer ceramic capacitors, feed-through types integrate the ground connection into the component body, reducing loop inductance significantly.

Replacement Considerations

Substitutes must match the 1806 footprint, 0.033 µF capacitance, 100V rating, and three-terminal feed-through topology. Verify that alternative parts maintain similar high-frequency impedance characteristics and thermal stability ratings.
