1812Y2000393MJTE03

Overview

The Knowles Syfer 1812Y2000393MJTE03 is a surface-mount multilayer ceramic capacitor (MLCC) designed for high-reliability applications. It features a capacitance of 39,000 pF with a tolerance of ±20%. The component utilizes an X7R dielectric material and supports a DC voltage rating of 20 V. Housed in a standard 1812 (4532 metric) package, it operates within a temperature range of -55°C to +125°C. This part belongs to the FlexiCap series, incorporating flexible terminations to enhance mechanical durability.

Feature Summary

• Incorporates FlexiCap technology with flexible terminations to absorb board flex stress and prevent cracking.
• Utilizes X7R dielectric material to provide stable capacitance performance across a wide operating temperature range.
• Designed for surface-mount assembly in compact electronic layouts.

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 termination configuration and RoHS compliance status directly with the manufacturer or authorized distributors before procurement. Confirm that the flexible termination variant matches the mechanical requirements of the target PCB layout. Ensure supply chain sources are authorized to guarantee component authenticity and traceability.

Selection Notes

Select this component when board flex resistance is critical due to its flexible termination structure. The X7R dielectric offers a balance of capacitance density and stability suitable for general applications. Verify that the 20V rating and 39,000 pF value align with the circuit design requirements compared to rigid-termination alternatives.

Part Context

This part belongs to the Knowles Syfer 1812Y series, which specializes in high-reliability MLCCs. The series is widely recognized for automotive-grade components featuring FlexiCap technology. These capacitors are engineered to withstand mechanical stress during assembly and operation, making them distinct from standard rigid-termination MLCCs.

Replacement Considerations

Direct substitutes must match the 1812 footprint, 20V rating, 39,000 pF capacitance, and X7R dielectric. Crucially, replacements should also feature flexible terminations if board flex resilience is required. Verify AEC-Q200 certification if used in automotive contexts.
