1206J0500223MXTE07

Overview

The Knowles Syfer 1206J0500223MXTE07 is a three-terminal feed-through capacitor designed for surface mount applications. It features a capacitance of 0.022 µF (22 nF) with a ±20% tolerance and a DC voltage rating of 50 VDC. The component utilizes X7R dielectric material and operates within a temperature range of -55°C to +125°C. Housed in a 1206 (3216 metric) package, it measures 3.2 mm in length, 1.6 mm in width, and 1.1 mm in height. The termination structure incorporates a nickel barrier with 100% tin plating.

Feature Summary

• Three-terminal EMI filter architecture providing superior high-frequency noise suppression compared to standard two-terminal capacitors.
• Feed-through design that minimizes parasitic inductance for effective electromagnetic interference mitigation.
• Robust mechanical construction utilizing nickel barrier terminations for enhanced solderability and reliability.

Applications

• High-speed digital signal line filtering in communication equipment.
• Power supply input/output decoupling in sensitive electronic circuits.
• EMI suppression in automotive electronics and industrial control systems.

Procurement Notes

Verify the complete part number including suffixes against official manufacturer documentation to ensure correct termination and dielectric specifications. Confirm RoHS compliance status and specific packaging requirements such as reel quantities prior to ordering. Cross-reference datasheet revision dates to validate parameter accuracy for your specific application timeline.

Selection Notes

Select this component when low parasitic inductance is critical for EMI performance in space-constrained designs. The 1206 footprint offers a balance between current handling capability and board area efficiency. Ensure the operating voltage remains below the 50 VDC rating and consider the thermal environment given the X7R dielectric characteristics across the specified temperature range.

Part Context

This component belongs to the Knowles Syfer family of surface mount feed-through capacitors. These devices are engineered to replace traditional discrete filters by integrating filtering functions directly into the capacitor structure. The series is recognized for its ability to handle significant ripple currents while maintaining compact dimensions suitable for modern dense PCB layouts.

Replacement Considerations

Direct substitutes include other 1206 package three-terminal capacitors from Knowles Syfer with matching capacitance and voltage ratings, such as the 1206J0500473MXTE07 or 1206J0500204MXTE07. Verify pinout compatibility and physical dimensions before substituting to ensure proper fit and electrical performance equivalence.
