1806J1000104MXTE01

Overview

The Knowles Syfer 1806J1000104MXTE01 is a surface-mount multilayer ceramic feed-through capacitor designed for high-frequency noise suppression. It features an X7R dielectric with a capacitance of 0.1 µF and a voltage rating of 100 VDC. The component utilizes a three-terminal architecture within an 1806 (4516 metric) package, providing superior electromagnetic interference filtering compared to standard two-terminal designs. It offers a tolerance of ±20% and operates reliably across a temperature range of -55°C to +125°C.

Feature Summary

• Three-terminal feed-through architecture enables effective shunting of high-frequency noise to ground while maintaining signal integrity on the central conductor.

Applications

• High-speed digital circuit power distribution network decoupling
• RF module power input filtering
• EMI suppression in compact mobile device layouts

Procurement Notes

Verify the specific suffix 'E01' against official datasheets to confirm the three-terminal feed-through configuration, as generic MLCC listings may omit this critical structural detail. Ensure compatibility with automated pick-and-place equipment regarding the 1806 footprint dimensions and terminal placement. Cross-reference RoHS compliance documentation for final assembly requirements.

Selection Notes

Select this component when space-constrained PCB layouts require the noise attenuation performance of a three-terminal filter without increasing the board area. The X7R dielectric provides stable capacitance characteristics suitable for general-purpose decoupling applications where moderate temperature stability is sufficient. Evaluate the trade-off between the higher insertion loss of feed-through designs versus standard MLCCs for your specific frequency spectrum requirements.

Part Context

This part belongs to the Knowles Syfer E01 series of feed-through capacitors, which are engineered specifically for integrated EMI filtering in modern electronics. Unlike standard capacitors, these components integrate the ground connection directly into the package structure, minimizing parasitic inductance. This design philosophy addresses the growing need for efficient noise control in densely packed consumer and industrial electronic assemblies.

Replacement Considerations

Direct substitutes must match the 1806 footprint, 100V rating, 0.1µF value, and critically, the three-terminal feed-through topology. Standard two-terminal 1806 MLCCs are not electrically equivalent replacements due to differences in parasitic inductance and filtering efficacy.
