1812J2000472MXTE03

Overview

The Knowles Syfer 1812J2000472MXTE03 is a feed-through multilayer ceramic capacitor designed for surface-mount applications. It features a capacitance of 4700 pF with a voltage rating of 200 VDC and a tolerance of 20%. The component utilizes an X7R dielectric material and operates within a temperature range of -55°C to +125°C. Housed in an 1812 (4532 metric) package, it includes a 50 mA current rating specification typical for feed-through architectures.

Feature Summary

• Feed-through architecture providing integrated filtering capabilities
• High reliability construction suitable for demanding environments
• Surface-mount design for automated assembly integration

Applications

• RF circuit filtering
• Power supply noise suppression
• EMI/RFI interference mitigation

Procurement Notes

Verify the specific XT series designation and E03 suffix against official manufacturer documentation to confirm exact termination and packaging specifications. Ensure compatibility with high-frequency signal paths where feed-through characteristics are required rather than standard MLCC behavior.

Selection Notes

Select this component when space-constrained designs require combined decoupling and filtering functions. The 1812 footprint offers a balance between capacitance density and thermal management. Confirm that the 200V rating aligns with peak transient voltages in the target application circuit.

Part Context

This part belongs to the Knowles Syfer XT series of high-reliability capacitors. The XT series is engineered for aerospace, defense, and industrial sectors requiring robust performance under extreme conditions. Feed-through variants provide superior common-mode noise rejection compared to standard parallel-plate capacitors.
