1206J0250223MXTE01

Overview

The Knowles Syfer 1206J0250223MXTE01 is a surface-mount feedthrough capacitor designed for EMI filtering. It features a capacitance of 0.022 µF with a ±20% tolerance and an X7R dielectric. The component has a DC voltage rating of 50V and operates within a temperature range of -55°C to +125°C. It utilizes a 1206 (3216 metric) package with dimensions of 3.20mm x 1.60mm x 1.30mm maximum height. The device provides an insertion loss of 43dB at 100MHz and supports a current rating of 300mA.

Feature Summary

• Integrated three-terminal EMI filter architecture
• High insertion loss performance at 100MHz
• Nickel barrier electrode construction
• RoHS3 compliant composition

Applications

• General purpose EMI suppression in electronic circuits
• Power line filtering applications
• Signal integrity protection in compact modules

Procurement Notes

Verify the specific datasheet version, as ordering suffixes may indicate variations in termination or packaging. Confirm that the 50V rating aligns with your circuit requirements. Ensure compatibility with standard 1206 footprints during layout design. Check for RoHS3 compliance if required by your manufacturing standards. Validate the 300mA current handling capability against peak load conditions.

Selection Notes

Select this component when integrated EMI filtering is required in a small form factor. The X7R dielectric offers stable capacitance over temperature. Consider the 300mA current limit for power lines. The 1206 size balances footprint constraints with electrical performance. Verify insertion loss specifications meet system noise immunity targets.

Part Context

This part belongs to the Knowles Syfer EMI Filter series, specifically the E01 type. It is a multilayer ceramic capacitor configured as a feedthrough device. The product line focuses on high-performance noise suppression in compact surface-mount packages. It is distinct from standard MLCCs due to its internal terminal structure.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires matching capacitance, voltage rating, package size, and insertion loss characteristics. Consult manufacturer catalogs for direct equivalents.
