1806J0250223MXTE07

Overview

The Knowles Syfer 1806J0250223MXTE07 is a high-reliability multilayer ceramic capacitor (MLCC) designed for surface-mount technology. It features a 1806 (4516 metric) case size with a capacitance of 0.022 µF and a DC voltage rating of 25 VDC. The component utilizes X7R dielectric material, providing a capacitance tolerance of ±20%. It operates within a temperature range of -55°C to +125°C. This specific part number identifies a three-terminal EMI filter configuration, incorporating a nickel barrier and 100% tin termination system to enhance electromagnetic interference suppression capabilities.

Feature Summary

• Three-terminal EMI filter architecture for enhanced noise suppression
• Nickel barrier and 100% tin termination system
• X7R dielectric for stable performance across wide temperature ranges

Applications

• High-frequency signal line filtering in electronic circuits
• Power supply input/output decoupling for EMI reduction
• Sensitive analog circuit protection against electromagnetic interference

Procurement Notes

Verify the exact suffix MXTE07 to confirm the three-terminal EMI filter variant, as standard MLCCs share similar base codes but lack the internal filter structure. Confirm RoHS compliance status through official datasheets. Ensure compatibility with PCB footprints designed specifically for three-terminal components, which differ from standard two-terminal MLCC layouts. Check for any specific handling requirements related to the nickel barrier terminations during assembly processes.

Selection Notes

Select this component when EMI suppression is critical in space-constrained applications requiring a 1806 footprint. The three-terminal design offers superior high-frequency attenuation compared to standard capacitors. Ensure the 25V rating meets the circuit's peak voltage requirements. Consider the X7R characteristics for applications where moderate capacitance stability over temperature is sufficient. Verify that the PCB layout supports the specific terminal arrangement required for effective grounding and filtering.

Part Context

This component belongs to the Knowles Syfer high-reliability MLCC family, specifically engineered for demanding environments. The 1806 case size balances physical footprint with electrical performance. As an EMI filter capacitor, it integrates filtering functionality directly into the passive component, reducing board space and complexity. The product line emphasizes robustness and consistent performance in industrial and commercial electronics.

Replacement Considerations

Direct substitutes must match the three-terminal EMI filter topology, not just capacitance and voltage. Compare internal resistance and impedance characteristics for equivalent filtering performance. Verify identical termination materials and case dimensions for mechanical compatibility. Standard two-terminal MLCCs are not functional replacements due to the lack of integrated filtering structure.
