1806J1000391MCTE01

Overview

The Knowles Syfer 1806J1000391MCTE01 is a three-terminal EMI filter capacitor in the 1806 (4516 metric) surface-mount package. It features a C0G (NP0) dielectric with a capacitance of 390 pF and a tolerance of ±20%. The device has a DC voltage rating of 100 VDC and operates within a temperature range of -55°C to +125°C. It utilizes a nickel barrier electrode structure with 100% tin terminations for solderability.

Feature Summary

• Three-terminal architecture designed for effective electromagnetic interference suppression
• C0G (NP0) dielectric material ensures stable capacitance characteristics across varying temperatures
• Nickel barrier electrode construction provides robust mechanical integrity

Applications

• High-frequency signal line filtering in communication equipment
• Power supply input/output noise suppression in industrial electronics
• EMI mitigation in automotive electronic control units

Procurement Notes

Verify the specific suffix 'E01' against official datasheets to confirm the three-terminal configuration, as standard two-terminal variants may share similar base part numbers. Ensure compatibility with automated pick-and-place equipment regarding the 1806 footprint dimensions. Confirm RoHS compliance status through current manufacturer documentation prior to integration into regulated assemblies.

Selection Notes

Select this component when high-frequency noise attenuation is required in space-constrained designs. The three-terminal design offers superior grounding paths compared to standard two-terminal capacitors. Consider the 100V rating and 390pF value for coupling or decoupling applications where precise capacitance stability is critical under thermal stress conditions.

Part Context

This component belongs to the Knowles Syfer E01 series of feed-through style MLCCs. These devices integrate capacitor functionality with shielding properties inherent to the three-terminal layout. The series targets applications demanding reliable EMI performance in compact form factors without compromising electrical stability.

Replacement Considerations

Direct substitutes must match the 1806 footprint, 390pF capacitance, 100V rating, and three-terminal topology. Verify that alternative manufacturers offer C0G dielectrics and compatible termination materials for equivalent thermal cycling reliability.
