Overview
The Knowles Syfer 1206J1000472MJTE03 is a surface-mount feed-through capacitor designed for high-frequency noise suppression. It features a capacitance of 4700 pF with a tolerance of ±20%. The component is rated for a DC voltage of 100 V and supports a continuous current of 50 mA. Constructed with X7R dielectric material, it operates within a temperature range of -55°C to +125°C. The device utilizes a 1206 (3216 metric) package footprint for standard SMD/SMT assembly.
Feature Summary
- Integrated feed-through architecture providing simultaneous signal conduction and EMI filtering in a single compact component.
Applications
- High-speed data line protection
- RF circuit noise suppression
- Signal integrity enhancement in dense PCB layouts
Procurement Notes
Verify the specific suffix MJTE03 against official manufacturer documentation to confirm the exact current rating and termination specifications. Ensure compatibility with automated pick-and-place equipment regarding the 1206 package dimensions. Confirm RoHS compliance status through the latest environmental declaration provided by Knowles Syfer prior to final procurement.
Selection Notes
Select this component when space constraints require combining a series resistor or inductor function with capacitive filtering. The 50 mA current rating dictates suitability for low-power signal lines rather than power distribution. Evaluate the insertion loss characteristics at target frequencies to ensure adequate attenuation without excessive signal degradation.
Part Context
This part belongs to the Knowles Syfer EMI Filter series, specifically utilizing the E01/E07 type construction. These components are engineered to replace traditional discrete RLC networks, simplifying board layout while maintaining effective high-frequency interference rejection in sensitive electronic applications.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Verify pinout and electrical parameters before considering any alternative feed-through capacitor models from other manufacturers.
