Overview
The Knowles Syfer 1206J0500223MXTE01 is a three-terminal surface-mount EMI filter capacitor housed in a 1206 (3216 metric) package. It features an X7R dielectric with a capacitance of 0.022 µF and a DC voltage rating of 50V. The component has a tolerance of ±20% and operates within a temperature range of -55°C to +125°C. It provides 43dB insertion loss at 100MHz and supports a current rating of 300mA.
Feature Summary
- Three-terminal architecture for enhanced high-frequency noise suppression
- Integrated EMI filtering capability via feedthrough design
- X7R dielectric material ensuring stable performance across wide temperature ranges
Applications
- High-frequency noise suppression in sensitive electronic circuits
- EMI filtering in signal lines requiring compact form factors
- Power distribution networks needing localized decoupling and filtering
Procurement Notes
Verify the complete part number including suffixes against official manufacturer documentation to ensure correct termination and packaging specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration into production workflows.
Selection Notes
Select this component when space-constrained designs require integrated EMI filtering without additional discrete components. The three-terminal structure offers superior high-frequency attenuation compared to standard two-terminal capacitors in similar packages.
Part Context
This component belongs to the Knowles Syfer EMI Filter series, specifically designed for surface-mount applications. It utilizes advanced ceramic technology to provide reliable noise suppression in compact electronic assemblies where traditional filtering solutions may be too large or ineffective at higher frequencies.
Replacement Considerations
Consult official substitution guides for compatible three-terminal EMI filters in the 1206 package. Verify electrical parameters such as capacitance, voltage rating, and insertion loss characteristics before considering alternative manufacturers.
