0805J0250182MJTE07

Overview

The Knowles Syfer 0805J0250182MJTE07 is a multilayer ceramic capacitor (MLCC) designed as a three-terminal EMI filter. It features an X7R dielectric with a capacitance of 1.8 nF and a tolerance of ±20%. The component has a DC voltage rating of 25 VDC and operates within a temperature range of -55°C to +125°C. Housed in an 0805 (2012 metric) surface-mount package, it utilizes nickel barrier terminations with 100% tin plating for solderability.

Feature Summary

• Three-terminal architecture provides enhanced electromagnetic interference filtering performance compared to standard two-terminal capacitors.
• X7R dielectric material ensures stable capacitance characteristics across the specified operating temperature range.
• Nickel barrier termination system with 100% tin plating offers reliable soldering and corrosion resistance.

Applications

• High-frequency noise suppression in sensitive electronic circuits
• Power supply input filtering for integrated circuits
• Signal line protection against electromagnetic interference

Procurement Notes

Verify the specific suffix 'MJTE07' to confirm the three-terminal EMI filter configuration, as standard MLCC part numbers may differ. Ensure compatibility with PCB footprints designed for three-terminal components rather than standard two-terminal pads. Confirm RoHS compliance status through official manufacturer documentation prior to integration into regulated assemblies.

Selection Notes

Select this component when superior high-frequency attenuation is required over conventional capacitors. The three-terminal design allows for lower effective series inductance, improving filtering efficiency at higher frequencies. Consider the 25V rating and 1.8nF value relative to circuit requirements. Verify that the 0805 footprint accommodates the specific terminal layout of this EMI filter variant.

Part Context

This component belongs to the Knowles Syfer high-reliability MLCC family, specifically engineered for demanding environments. The 0805J series denotes a standard 0805 case size with a 25V rating. The inclusion of the EMI filter designation distinguishes it from general-purpose capacitors by offering improved parasitic performance for noise reduction applications.

Replacement Considerations

Direct substitutes must match the three-terminal EMI filter topology, not just capacitance and voltage. Standard two-terminal 0805 capacitors will not provide equivalent filtering performance. Verify pinout compatibility and thermal characteristics before substituting with other manufacturers' EMI filter components.
