1206J0500392MJTE07

Overview

The Knowles Syfer 1206J0500392MJTE07 is a surface-mount feed-through capacitor designed for EMI suppression. It features a 3900 pF capacitance with ±20% tolerance and a 50 VDC voltage rating. The component utilizes C0G (NP0) dielectric material, ensuring stable performance across an operating temperature range of -55°C to +125°C. Housed in a standard 1206 (3216 metric) package, it integrates a center terminal structure to handle high current loads up to 2 A while providing effective noise filtering.

Feature Summary

• Integrates a center terminal architecture to facilitate high-current signal transmission alongside noise attenuation
• Provides electromagnetic interference suppression through specialized feed-through capacitor design
• Maintains electrical stability using C0G (NP0) ceramic dielectric material

Applications

• High-speed data line filtering in communication equipment
• EMI suppression in automotive electronic control units
• Noise reduction in industrial power supply circuits

Procurement Notes

Verify the specific suffix codes against official manufacturer documentation to confirm terminal configuration and termination plating specifications. Ensure that the selected variant matches the required current handling capabilities and thermal ratings for the intended application environment before finalizing procurement orders.

Selection Notes

Select this component when circuit designs require simultaneous high-current carrying capacity and effective high-frequency noise filtration. The choice depends on verifying compatibility with the target PCB footprint dimensions and confirming that the 50V DC rating exceeds the maximum operational voltage peaks within the system.

Part Context

This part belongs to the Knowles Syfer series of high-reliability multilayer ceramic capacitors. It represents a specialized category of feed-through devices distinct from standard parallel-plate MLCCs, engineered specifically for applications demanding robust electromagnetic interference mitigation without compromising signal integrity or current throughput.
