0805J0250392MJTE07

Overview

The Knowles Syfer 0805J0250392MJTE07 is a multilayer ceramic capacitor (MLCC) designed for surface mount technology. It features a capacitance of 3900 pF with a tolerance of ±20%. The component operates at a DC voltage rating of 25 VDC and utilizes X7R dielectric material. It is housed in an 0805 (2012 metric) package with standard SMD/SMT terminations. The device supports an operating temperature range from -55°C to +125°C.

Feature Summary

• Utilizes X7R dielectric material for stable capacitance characteristics across varying temperatures.
• Designed as a three-terminal EMI filter configuration with nickel barrier and 100% tin terminations.

Applications

• General purpose decoupling in surface mount circuits
• EMI filtering applications requiring three-terminal configurations
• Boardflex sensitive environments

Procurement Notes

Verify the specific suffix 'MJTE07' against official datasheets to confirm the X7R dielectric and three-terminal EMI filter structure, as generic 0805J series parts may vary. Ensure compatibility with automated pick-and-place equipment regarding the reel packaging format. Confirm RoHS compliance status through current manufacturer documentation before finalizing procurement specifications.

Selection Notes

Select this component when a 3900 pF capacitance value is required within a compact 0805 footprint. The X7R dielectric offers higher volumetric efficiency compared to C0G types but exhibits greater capacitance variation with voltage and temperature. Verify that the ±20% tolerance meets circuit requirements and that the 25V rating provides adequate margin for the application's maximum operating voltage.

Part Context

This part belongs to the Knowles Syfer high-reliability MLCC portfolio. The 0805J series designation typically indicates general-purpose or automotive-grade components depending on specific qualification levels. The manufacturer emphasizes robust termination systems suitable for high-volume surface mount assembly processes.

Replacement Considerations

Direct substitutes include other 0805 X7R capacitors with 3900 pF ±20% tolerance and 25V rating. Verify terminal configuration compatibility if the original design relies on the specific three-terminal EMI filter topology.
