1806J0500823MXTE01

Overview

The Knowles Syfer 1806J0500823MXTE01 is a surface-mount multilayer ceramic capacitor (MLCC) designed as a three-terminal EMI filter. It features an 82 nF capacitance with a ±20% tolerance, rated for 50 VDC using X7R dielectric material. The component utilizes a standard 1806 (4516 metric) package size and employs nickel barrier terminations with 100% tin plating. It operates within a temperature range of -55°C to +125°C.

Feature Summary

• Three-terminal architecture providing enhanced electromagnetic interference suppression compared to standard two-terminal capacitors
• X7R ceramic dielectric ensures stable capacitance performance across the specified operating temperature range
• Nickel barrier termination structure with 100% tin plating supports reliable surface mount reflow soldering processes

Applications

• High-frequency noise filtering in sensitive analog signal lines
• Power supply decoupling where common-mode interference reduction is required
• EMI suppression in compact consumer electronic devices utilizing 1806 footprints

Procurement Notes

Verify the complete part number including the suffix TE01 to ensure correct packaging configuration. Confirm that the X7R dielectric characteristics align with circuit stability requirements under varying thermal conditions. Check RoHS compliance documentation for specific regional regulatory adherence before finalizing procurement orders.

Selection Notes

Select this component when space constraints require an 1806 footprint but superior high-frequency attenuation is needed over standard MLCCs. The three-terminal design offers better parasitic inductance performance. Ensure the 50V rating provides sufficient margin for the maximum DC bias voltage present in the target application circuit.

Part Context

This component belongs to the Knowles Syfer 1806J series of surface-mount EMI filters. These parts integrate capacitor functionality with shielding structures to minimize electromagnetic interference. The series is engineered for applications demanding compact form factors with effective noise suppression capabilities in dense PCB layouts.

Replacement Considerations

Direct substitutes must match the 1806 package, 82 nF capacitance, 50V rating, and three-terminal topology. Verify that alternative manufacturers offer compatible nickel barrier terminations and X7R dielectric properties to maintain electrical and mechanical equivalence.
