1812J2000472MCTE03

Overview

The Knowles Syfer 1812J2000472MCTE03 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%, rated for a DC voltage of 200 V and a current handling capacity of 50 mA. The component utilizes C0G (NP0) dielectric material to ensure stable performance across an operating temperature range of -55°C to +125°C. Housed in a standard 1812 (4532 metric) package, it offers low parasitic inductance suitable for EMI filtering applications.

Feature Summary

• Integrated feed-through architecture provides effective electromagnetic interference suppression within a compact surface-mount footprint.
• C0G (NP0) dielectric construction maintains consistent electrical characteristics over wide temperature variations.
• High current handling capability supports direct integration into power lines without external bypass components.

Applications

• Electromagnetic interference filtering in automotive electronic control units
• Noise suppression in industrial motor drive circuits
• Power line conditioning in telecommunications equipment

Procurement Notes

Verify the specific suffix 'E03' against the manufacturer's official datasheet to confirm terminal configuration and packaging details. Ensure that the 50 mA current rating aligns with the target circuit requirements. Confirm RoHS compliance status through the latest environmental declaration provided by Knowles Syfer before finalizing procurement specifications.

Selection Notes

Select this component when space-constrained designs require integrated filtering and power delivery. The 1812 package balances current capacity with board area efficiency. Consider the ±20% tolerance if precise capacitance values are not critical. Evaluate the 200 VDC rating against peak transient voltages in the application environment to ensure reliable operation.
