0805J0500102MJTE03

Overview

The Knowles Syfer 0805J0500102MJTE03 is a surface-mount feed-through capacitor designed for high-frequency noise suppression. It features a 1000 pF capacitance with ±20% tolerance and a 50 VDC voltage rating. Utilizing X7R dielectric material, the component operates within a temperature range of -55°C to +125°C. The device employs a nickel barrier with 100% tin termination and offers a rated current capacity of 50 mA.

Feature Summary

• Integrates a three-terminal feed-through architecture to provide superior high-frequency noise attenuation compared to standard two-terminal capacitors.
• Features a low-inductance internal structure that maintains effective filtering performance at elevated frequencies.
• Constructed with a robust metal frame and nickel barrier termination system to ensure reliable soldering and mechanical stability.

Applications

• High-speed digital signal line filtering
• Power supply decoupling in sensitive circuits
• EMI suppression on data buses

Procurement Notes

Verify the specific suffix 'E03' against official datasheets to confirm the presence of the feed-through structure and terminal configuration. Ensure the selected variant matches the required 50 mA current rating and 0805 footprint dimensions for your PCB layout constraints.

Selection Notes

Select this component when standard MLCCs fail to suppress high-frequency noise due to parasitic inductance. The feed-through design is essential for applications requiring significant attenuation above 100 MHz. Confirm that the 50 mA current handling capability meets the circuit's operational requirements.

Part Context

This part belongs to the Knowles Syfer E03 series of feed-through capacitors. These components are engineered specifically for EMI/RFI suppression in compact surface-mount designs. The series provides enhanced filtering capabilities while maintaining compatibility with standard SMT assembly processes.

Replacement Considerations

Direct substitutes include other 0805 feed-through capacitors from Knowles Syfer with identical electrical ratings. Verify that any alternative maintains the same three-terminal topology and current handling specifications.
