1812J5000153MXTE03

Overview

The Knowles Syfer 1812J5000153MXTE03 is a surface-mount EMI filter capacitor in the 1812 (4532 metric) package. It features X7R dielectric with a capacitance of 15 nF and a voltage rating of 500 VDC. The component operates within a temperature range of -55°C to +125°C and has a tolerance of ±20%. It utilizes flexible terminal technology for enhanced mechanical reliability.

Feature Summary

• Integrated EMI filtering capability for noise suppression
• Flexible terminal construction for board flex sensitivity
• High voltage rating suitable for robust circuit protection

Applications

• Board-flex sensitive electronic assemblies
• Automotive electronics requiring AEC-Q200 compliance
• General purpose EMI suppression circuits

Procurement Notes

Verify the specific suffix MXTE03 against official datasheets to confirm the EMI filter variant and flexible terminal configuration. Ensure compatibility with automated placement equipment due to the 1812 footprint dimensions. Confirm RoHS and REACH status requirements prior to integration into regulated supply chains.

Selection Notes

Select this component when high-voltage EMI filtering is required in space-constrained designs. The X7R dielectric provides stable performance across the specified temperature range. Flexible terminals are critical for applications subject to mechanical stress or PCB warping during assembly and operation.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, designed specifically for applications where standard rigid terminations may fail under mechanical strain. The 1812J base indicates a 500V rated general type MLCC, modified here with EMI filtering characteristics and flexible ends.
