1806J2000223MJTE07

Overview

The Knowles Syfer 1806J2000223MJTE07 is a surface-mount feed-through capacitor designed for EMI suppression. It features a capacitance of 0.022 µF with a ±20% tolerance and a DC voltage rating of 200 VDC. The component utilizes X7R (2R1) dielectric material and is housed in a standard 1806 (4516 metric) package. It operates within a temperature range of -55°C to +125°C and includes nickel barrier terminations.

Feature Summary

• Three-terminal feed-through architecture providing effective common-mode noise attenuation
• X7R dielectric composition ensuring stable capacitance across the operating temperature range
• Nickel barrier termination system offering reliable solderability and corrosion resistance

Applications

• High-frequency signal line filtering in electronic assemblies
• Power supply input/output decoupling for noise reduction
• EMI suppression in compact surface-mount circuit designs

Procurement Notes

Verify the specific suffix codes against official manufacturer documentation to confirm exact termination plating and packaging configuration. Ensure compatibility with automated pick-and-place equipment regarding the reel or cut-tape format. Cross-reference the RoHS compliance status with current regulatory requirements before finalizing procurement orders.

Selection Notes

Select this component when high capacitance density is required in a small 1806 footprint for EMI applications. The X7R dielectric provides higher volumetric efficiency compared to C0G types, suitable for general-purpose filtering where moderate temperature stability is acceptable. Evaluate the 200V rating against peak circuit voltages to ensure adequate safety margins.
