1206J1000390MCTE07

Overview

The Knowles Syfer 1206J1000390MCTE07 is a three-terminal feed-through multilayer ceramic capacitor (MLCC) designed for surface mount technology. It features a 1206 (3216 metric) case size with a capacitance of 39 pF and a DC voltage rating of 100 VDC. The component utilizes C0G/NP0 dielectric material, ensuring stable performance across varying conditions. It offers a tolerance of ±20% and operates within a temperature range of -55°C to +125°C. The device incorporates a nickel barrier electrode structure with 100% tin terminations, providing robust solderability and reliability for high-frequency applications.

Feature Summary

• Three-terminal feed-through architecture enables effective electromagnetic interference filtering in compact layouts
• C0G/NP0 dielectric ensures minimal capacitance variation over temperature and voltage changes
• Nickel barrier electrode construction provides enhanced mechanical strength and corrosion resistance

Applications

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

Procurement Notes

Verify the specific suffix E07 against the manufacturer's current datasheet to confirm terminal configuration and packaging details. Ensure compatibility with PCB footprint requirements for three-terminal components. Confirm RoHS compliance status through official documentation prior to integration into regulated assemblies.

Selection Notes

Select this component when space-constrained designs require integrated filtering capabilities without additional discrete inductors or capacitors. The 1206 package balances current handling capacity with board area efficiency. Consider the ±20% tolerance if precise capacitance values are not critical for the circuit function.

Part Context

This part belongs to the Knowles Syfer J-series of high-reliability MLCCs. It is distinct from standard two-terminal capacitors due to its internal ground connection, which minimizes parasitic inductance. The series is engineered for demanding environments where signal integrity and noise reduction are paramount.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Verify pinout and electrical specifications carefully when considering alternative manufacturers' feed-through capacitors.
