0805J1000470MCTE07

Overview

The Knowles Syfer 0805J1000470MCTE07 is a multilayer ceramic capacitor (MLCC) designed as a surface-mount EMI filter. It features a three-terminal X2Y architecture within an 0805 (2012 metric) package. The component provides a capacitance of 47 pF with a voltage rating of 100 VDC and a tolerance of ±20%. Constructed with C0G/NP0 dielectric material, it ensures stable performance across a temperature range of -55°C to +125°C. The device utilizes a nickel barrier and 100% tin termination system for reliable soldering.

Feature Summary

• Three-terminal X2Y structure providing simultaneous common-mode and differential-mode noise suppression
• Compact 0805 footprint enabling high-density circuit board layouts
• C0G/NP0 dielectric material ensuring minimal capacitance variation over temperature and voltage
• Nickel barrier and 100% tin terminations for robust surface-mount reliability

Applications

• High-speed data line filtering in portable electronics
• EMI suppression on power distribution networks
• Signal integrity protection in communication interfaces
• Noise reduction in automotive electronic control units

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm terminal composition and packaging format. Ensure the selected variant matches the required voltage derating and capacitance tolerance for the target application environment. Cross-reference the datasheet for moisture sensitivity levels and reflow soldering profiles to guarantee assembly compatibility.

Selection Notes

Select this component when space-constrained designs require integrated EMI filtering without additional discrete components. The X2Y topology offers superior noise attenuation compared to standard two-terminal capacitors in similar footprints. Evaluate the operating voltage against peak transient signals to prevent dielectric breakdown. Confirm that the low equivalent series inductance meets the high-frequency noise suppression requirements of the circuit.

Part Context

This part belongs to the Knowles Syfer X2Y family of passive components. These devices integrate multiple capacitor functions into a single monolithic structure. The series is engineered for applications demanding significant electromagnetic interference reduction in compact form factors. The technology replaces traditional filter networks, simplifying bill-of-materials and reducing assembly complexity.

Replacement Considerations

Direct substitutes must match the 0805 package, 47 pF capacitance, and 100 V rating. Verify that alternative X2Y components maintain comparable insertion loss characteristics. Check for pinout compatibility if replacing with non-X2Y filters. Ensure the replacement part meets the same AEC-Q200 or industrial reliability standards if used in automotive contexts.
