1206J0500393MJTE07

Overview

The Knowles Syfer 1206J0500393MJTE07 is a surface-mount multilayer ceramic capacitor (MLCC) designed for high-reliability applications. It features a 1206 (3216 metric) package size with X7R dielectric characteristics. The component offers a capacitance of 39 nF with a tolerance of ±20% and a DC voltage rating of 50V. It operates within a temperature range of -55°C to +125°C and utilizes nickel barrier end terminations with 100% tin plating.

Feature Summary

• High-temperature stability utilizing X7R dielectric material
• Robust construction with nickel barrier and 100% tin end terminations
• Designed for high-reliability electronic circuits

Applications

• High-reliability industrial electronics
• Automotive circuitry requiring robust components
• General-purpose high-voltage filtering

Procurement Notes

Verify the specific suffix 'MJTE07' against official Knowles Syfer documentation, as standard listings often reference 'MXTE07'. Confirm RoHS compliance status and moisture sensitivity level (MSL) ratings directly from the manufacturer's datasheet before integration into production schedules.

Selection Notes

Select this component when a 1206 footprint is required for 50V applications needing stable capacitance across varying temperatures. The X7R dielectric provides a balance between capacitance density and thermal stability suitable for general high-reliability designs.

Part Context

This part belongs to the Knowles Syfer 1206J series of high-reliability MLCCs. The series is characterized by its ability to withstand harsh environments and high voltages within the standard 1206 case size, making it a staple for critical infrastructure and automotive systems.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Verify compatibility with equivalent 1206 50V 39nF X7R capacitors from other manufacturers only after cross-referencing termination materials and reliability standards.
