1812Y1000124METE03

Overview

The Knowles Syfer 1812Y1000124METE03 is a surface-mount multilayer ceramic capacitor (MLCC) featuring a capacitance of 0.12 µF and a DC voltage rating of 100 VDC. It utilizes X7R dielectric material with a tolerance of ±20%. The component operates within a temperature range of -55°C to +125°C and is housed in an 1812 (4532 metric) package measuring 4.50 mm x 3.20 mm. It belongs to the FlexiCap series, designed for board-flex sensitive applications.

Feature Summary

• FlexiCap soft termination technology reduces stress on the ceramic body during PCB flexing
• X7R dielectric provides stable capacitance characteristics across the operating temperature range
• AEC-Q200 qualified for automotive reliability standards

Applications

• Automotive electronics requiring board-flex sensitivity
• High-reliability general-purpose circuits
• Board-flex sensitive surface mount assemblies

Procurement Notes

Verify the specific suffix 'ETE03' against official Knowles Syfer documentation to confirm packaging and terminal specifications. Ensure compatibility with AEC-Q200 requirements if used in automotive contexts. Confirm RoHS compliance status via the manufacturer datasheet before integration into production lines.

Selection Notes

Select this component when board flexing is a concern due to its soft termination design. The 100V rating and 0.12 µF value suit general decoupling or filtering needs. Verify that the 1812 footprint matches the PCB layout constraints and that the X7R temperature coefficient meets circuit stability requirements.
