1806J1000820MCTE01

Overview

The Knowles Syfer 1806J1000820MCTE01 is a three-terminal EMI filter capacitor in an 1806 (4516 metric) surface-mount package. It features a C0G dielectric with a capacitance of 82 pF and a DC voltage rating of 100 VDC. The component offers a tolerance of 20% and operates within a temperature range of -55°C to +125°C. Designed for high-frequency noise suppression, it utilizes a feed-through architecture to provide effective electromagnetic interference filtering in compact electronic assemblies.

Feature Summary

• Three-terminal feed-through architecture for enhanced EMI suppression
• C0G dielectric material ensuring stable capacitance characteristics
• Surface-mount design compatible with automated assembly processes

Applications

• High-frequency signal line filtering
• Power supply input/output noise reduction
• RF circuit interference mitigation

Procurement Notes

Verify the specific suffix configuration against official datasheets to confirm terminal plating and packaging details. Ensure compatibility with existing PCB footprints for three-terminal components. Cross-reference manufacturer part numbers directly to avoid substitution errors with similar two-terminal MLCCs or different series variants.

Selection Notes

Select this component when superior common-mode noise attenuation is required compared to standard two-terminal capacitors. The three-terminal design provides lower impedance paths for high-frequency noise. Consider the physical size constraints of the 1806 package and the thermal requirements of the C0G dielectric for the target operating environment.

Part Context

This component belongs to the Knowles Syfer E01 series of feed-through capacitors. These parts are engineered for demanding applications requiring reliable EMI performance. The series utilizes advanced ceramic materials to maintain stability across wide temperature ranges and frequencies.

Replacement Considerations

Direct substitutes must match the 1806 footprint, 82 pF capacitance, 100 VDC rating, and three-terminal feed-through structure. Verify that alternative parts offer comparable insertion loss characteristics and thermal stability.
