1812Y1000473MJTE03

Overview

The Knowles Syfer 1812Y1000473MJTE03 is a surface-mount multilayer ceramic capacitor (MLCC) featuring an X7R dielectric. It offers a capacitance of 47 nF with a ±20% tolerance and a DC voltage rating of 100 VDC. The component utilizes the FlexiCap technology with a nickel barrier termination, designed to enhance mechanical reliability under thermal stress. It is housed in a standard 1812 (4532 metric) package, measuring 4.5 mm in length, 3.2 mm in width, and up to 2.5 mm in height.

Feature Summary

• FlexiCap/Nickel Barrier termination structure for improved mechanical robustness
• X7R dielectric material providing stable capacitance characteristics over temperature
• Designed for high-reliability applications requiring resistance to thermal shock

Applications

• High-reliability electronic circuits
• Automotive electronics systems
• Industrial control equipment

Procurement Notes

Verify the specific suffix 'JTE03' against official datasheets to confirm the exact termination and packaging configuration. Ensure compatibility with RoHS3 standards if required by your assembly process. Cross-reference the manufacturer's part number directly to avoid confusion with similar X2Y or standard MLCC variants within the same series.

Selection Notes

Select this component when a 100V rated, 47nF X7R capacitor is needed in an 1812 footprint. The FlexiCap feature makes it suitable for environments with significant thermal cycling. Compare against standard terminations if mechanical stress is not a primary design constraint, as alternative terminations may offer different cost or availability profiles.

Part Context

This part belongs to the Knowles Syfer FlexiCap family, which specializes in capacitors with flexible terminations to withstand board flexing and thermal expansion mismatches. The 1812Y series typically denotes X7R dielectric types within this product line, distinguishing them from C0G/NP0 variants.

Replacement Considerations

Direct substitutes must match the 1812 package, 100V rating, 47nF value, X7R dielectric, and FlexiCap/Nickel Barrier termination. Verify that any replacement maintains the same physical dimensions and electrical characteristics to ensure fit and function.
