1206J0250473MJTE07

Overview

The Knowles Syfer 1206J0250473MJTE07 is a surface-mount feed-through capacitor designed for high-frequency noise suppression. It features a capacitance of 0.047 µF with a DC voltage rating of 25 V and a continuous current handling capability of 2 A. The component utilizes an X7R dielectric material, ensuring stable performance across a temperature range of -55°C to +125°C. Housed in a standard 1206 (3216 metric) package, it integrates a central conductor to minimize parasitic inductance, making it suitable for compact PCB layouts requiring effective EMI filtering.

Feature Summary

• Integrates a central conductor structure to achieve low parasitic inductance for superior high-frequency performance.
• Functions as a feed-through capacitor, combining signal passing capabilities with simultaneous noise attenuation.
• Utilizes X7R dielectric technology to maintain capacitance stability under varying thermal conditions.

Applications

• High-speed data line filtering in communication interfaces
• Power supply input stages for noise reduction
• EMI suppression in compact electronic modules

Procurement Notes

Verify the specific suffix 'MJTE07' against official manufacturer documentation to confirm the feed-through configuration and terminal type. Ensure compatibility with automated pick-and-place equipment regarding the 1206 footprint dimensions. Cross-reference the datasheet for precise soldering profiles and moisture sensitivity levels prior to assembly.

Selection Notes

Select this component when both signal transmission and noise filtering are required on the same trace. The 2 A current rating supports moderate power applications without significant self-heating. The 1206 form factor allows for space-constrained designs where traditional two-terminal capacitors would increase loop inductance. Verify that the 25 V rating exceeds the maximum operating voltage of the circuit.

Part Context

This part belongs to the Knowles Syfer 1206J series of high-reliability multilayer ceramic components. The series is engineered for demanding environments, offering robust mechanical strength and consistent electrical characteristics. The feed-through variant specifically addresses modern electronics needs for integrated filtering solutions that save board space compared to discrete filter networks.
