Overview
The Knowles Syfer 0805J0500222MXTE01 is a three-terminal EMI filter capacitor in an 0805 (2012 metric) surface-mount package. It features a capacitance of 2200 pF with a ±20% tolerance and utilizes X7R dielectric material. The component has a DC voltage rating of 50 VDC and operates within a temperature range of -55°C to +125°C. Termination consists of nickel barrier plating with 100% tin, ensuring compatibility with standard soldering processes.
Feature Summary
- Three-terminal architecture provides enhanced electromagnetic interference filtering performance compared to standard two-terminal capacitors.
- Flexible termination technology accommodates board bending and thermal cycling stress without cracking.
- Nickel barrier and 100% tin endures provide reliable solderability and corrosion resistance.
Applications
- High-frequency noise suppression in sensitive electronic circuits
- Power supply input/output filtering for signal integrity
- EMI mitigation in compact surface-mount assemblies
Procurement Notes
Verify the specific suffix 'E01' against official Knowles Syfer documentation to confirm exact termination and packaging specifications. Ensure the selected variant matches the required three-terminal configuration for EMI filtering applications. Cross-reference the Mouser part number 843-0805J0500222MXTE01 with manufacturer datasheets to validate current production status and compliance details before procurement.
Selection Notes
Select this component when high-frequency noise attenuation is required in space-constrained designs. The three-terminal structure offers superior RF bypassing capabilities over conventional MLCCs. Verify that the 50V rating and 2200pF value align with circuit requirements. Confirm that the 0805 footprint fits the PCB layout constraints and that the X7R temperature stability meets operational environmental needs.
Part Context
This component belongs to the Knowles Syfer E03 series of pass-through filter capacitors. These devices are designed for EMI suppression in portable and industrial electronics. The series combines high capacitance density with robust mechanical reliability, suitable for applications requiring strict electromagnetic compatibility standards.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source data. Consult official Knowles Syfer documentation or authorized distributors for verified equivalent components matching the electrical and mechanical specifications.
