1806J0500334MXTE07

Overview

The Knowles Syfer 1806J0500334MXTE07 is a three-terminal EMI filter capacitor in an 1806 (4516 metric) surface-mount package. It features a 330 nF capacitance with ±20% tolerance and utilizes X7R dielectric material. The component is rated for 50 VDC and operates within a temperature range of -55°C to +125°C. It employs nickel barrier end terminations with 100% tin plating.

Feature Summary

• Three-terminal architecture providing enhanced high-frequency noise attenuation for EMI suppression applications
• Nickel barrier termination structure ensuring reliable solderability and mechanical stability during reflow processes
• X7R dielectric composition offering stable capacitance performance across the specified industrial temperature range

Applications

• High-speed digital signal line filtering in communication equipment
• Power supply input/output decoupling in compact electronic modules
• EMI suppression in automotive infotainment and control systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm terminal configuration and plating specifications. Ensure the selected variant matches the required 1806 footprint dimensions and thermal characteristics for your PCB layout constraints.

Selection Notes

Select this component when space-constrained designs require superior high-frequency filtering compared to standard two-terminal MLCCs. The three-terminal design offers lower parasitic inductance, making it suitable for sensitive analog or high-speed digital circuits requiring robust noise isolation without increasing board area.

Part Context

This part belongs to the Knowles Syfer E07 series of feed-through capacitors. These components are engineered specifically for electromagnetic interference mitigation in dense circuit boards. The series provides a compact alternative to traditional through-hole filters while maintaining high reliability standards for demanding environments.

Replacement Considerations

Direct substitutes include other 1806 three-terminal EMI filters from Knowles Syfer with matching 330nF/50V ratings, such as the 1806J0500334MCTE01. Verify that any replacement maintains the same nickel barrier termination and X7R dielectric properties to ensure electrical compatibility.
