1806J0250104MXTE01

Overview

The Knowles Syfer 1806J0250104MXTE01 is a three-terminal EMI filter capacitor in an 1806 (4516 metric) surface-mount package. It features a 0.1 µF capacitance with ±20% tolerance and a 25 VDC voltage rating. Utilizing X7R dielectric, it operates between -55°C and +125°C. The component provides effective electromagnetic interference suppression through its internal C-filter topology, designed for high-reliability applications requiring compact footprint solutions.

Feature Summary

• Three-terminal architecture for enhanced common-mode noise attenuation
• Compact 1806 surface-mount form factor for space-constrained designs
• X7R dielectric material ensuring stable performance across wide temperature ranges

Applications

• High-frequency signal line filtering in communication equipment
• Power supply input/output decoupling in industrial control systems
• EMI suppression in automotive electronic control units

Procurement Notes

Verify the complete part number including the suffix MXTE01 to ensure correct packaging and termination specifications. Confirm RoHS compliance status via the official datasheet before integration. Cross-reference the manufacturer's latest documentation to validate current production status and any potential design changes affecting pinout or electrical characteristics.

Selection Notes

Select this component when low-profile EMI filtering is required in SMD assemblies. The three-terminal design offers superior high-frequency performance compared to standard two-terminal capacitors. Ensure the circuit voltage remains below 25 VDC and verify that the 0.1 µF value aligns with the target noise frequency spectrum requirements.

Part Context

This component belongs to the Knowles Syfer 1806 series of multilayer ceramic capacitors. It is specifically engineered as a three-terminal EMI chip filter rather than a standard discrete capacitor. The series is recognized for high reliability and consistent electrical properties in demanding electronic environments.

Replacement Considerations

Direct substitutes must match the 1806 package, 25V rating, 0.1µF value, and three-terminal configuration. Verify equivalent EMI attenuation characteristics and thermal stability before substitution.
