1812Y1000104MJTE03

Overview

The Knowles Syfer 1812Y1000104MJTE03 is a high-reliability multilayer ceramic capacitor (MLCC) designed for surface-mount applications. It features an X7R dielectric material providing stable capacitance characteristics across a wide temperature range. The component offers a nominal capacitance of 0.1 µF with a voltage rating of 100 VDC and a tolerance of ±20%. Housed in a standard 1812 (4532 metric) package, it measures 4.5 mm in length, 3.2 mm in width, and has a maximum height of 0.75 mm. It operates reliably between -55°C and +125°C.

Feature Summary

• High reliability construction suitable for demanding electronic environments
• X7R dielectric ensures consistent performance over the operating temperature range
• Flexible terminal design reduces stress on the capacitor body during board flexing

Applications

• Automotive electronics requiring AEC-Q200 compliance
• Board-flex sensitive circuit designs
• General-purpose decoupling and filtering in industrial equipment

Procurement Notes

Verify the specific suffix MJTE03 against official datasheets to confirm terminal type and packaging details. Ensure compatibility with automated pick-and-place equipment regarding the 1812 footprint. Confirm RoHS compliance status if required by your manufacturing standards. Cross-reference the manufacturer's latest documentation for any updates to the FlexiCap technology specifications.

Selection Notes

Select this component when high reliability and resistance to mechanical stress are critical. The X7R dielectric provides higher volumetric efficiency than C0G types while maintaining good stability. The flexible terminals make it ideal for substrates prone to warping or flexing. Consider the 1812 size for balancing capacitance density and physical robustness in space-constrained layouts.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, which utilizes flexible electrodes to enhance durability. The 1812Y prefix indicates a 100V DC rated device within the 1812 case size family. These capacitors are engineered for automotive and industrial sectors where standard MLCCs might fail due to thermal cycling or mechanical vibration.

Replacement Considerations

Direct substitutes must match the 1812 footprint, 100V rating, 0.1µF capacitance, and X7R dielectric. Verify that alternative parts also feature flexible terminals if board flex resistance is required. Check for equivalent AEC-Q200 qualification if used in automotive applications.
