1806J2000273MJTE07

Overview

The Knowles Syfer 1806J2000273MJTE07 is a surface-mount feed-through capacitor designed for EMI suppression. It features a 1806 (4516 metric) package with dimensions of 4.50mm x 1.60mm and a maximum height of 1.30mm. The component provides a capacitance of 0.027 µF (27 nF) with a voltage rating of 200 VDC and a tolerance of ±20%. It utilizes an X7R dielectric material, ensuring stable performance across a temperature range of -55°C to +125°C. The device supports a current rating of 2 A and employs nickel barrier terminations.

Feature Summary

• Integrated three-terminal feed-through architecture for effective electromagnetic interference filtering in compact layouts
• High current handling capability suitable for power line applications requiring robust signal integrity
• X7R dielectric composition providing reliable capacitance stability over a wide industrial temperature spectrum

Applications

• Electromagnetic interference filtering in electronic circuits
• Power supply input/output conditioning
• Signal line protection in communication equipment

Procurement Notes

Verify the specific termination finish and dielectric class against project requirements before ordering. Confirm that the 1806 footprint matches the PCB design guidelines. Ensure the 200V DC rating and 2A current capacity align with the operational environment. Check for RoHS compliance documentation if required by regulatory standards. Validate the supplier's authenticity through authorized distribution channels.

Selection Notes

Select this component when space constraints necessitate a 1806 package size while requiring significant current handling. The X7R dielectric offers a balance between capacitance density and cost compared to C0G types. Consider the 200V rating for moderate voltage applications. Evaluate thermal management needs given the operating temperature range up to 125°C. Compare against standard MLCCs if high-frequency filtering is not the primary objective.

Part Context

This part belongs to the Knowles Syfer family of surface-mount ceramic capacitors. The '1806' designation indicates the standardized EIA case size. The 'J' suffix typically denotes the voltage code within the manufacturer's coding system. The 'M' indicates the capacitance tolerance. This series is engineered for reliability in demanding electronic environments, focusing on noise reduction and signal purity.

Replacement Considerations

Direct substitutes must match the 1806 footprint, 200V rating, 27nF capacitance, and X7R dielectric. Verify that alternative components support at least 2A current handling. Ensure the replacement maintains similar parasitic inductance characteristics for equivalent EMI performance. Cross-reference termination materials for solderability compatibility.
