Overview
The Knowles Syfer 1812Y1000204MXTE03 is a FlexiCap multilayer ceramic capacitor (MLCC) designed for surface mount technology. It features a pass-through architecture with an X7R dielectric, providing a capacitance of 0.2 µF and a DC voltage rating of 100V. The component utilizes a ±20% tolerance and operates within a temperature range of -55°C to +125°C. Housed in a standard 1812 (4532 metric) package, it supports high-current applications through its low-inductance internal structure.
Feature Summary
- Pass-through architecture enabling high current handling capabilities
- X7R dielectric material ensuring stable performance across wide temperature ranges
- FlexiCap construction for enhanced mechanical reliability
Applications
- High-frequency power supply filtering
- EMI suppression in high-current circuits
- Decoupling for high-speed digital logic
Procurement Notes
Verify the specific suffix configuration against official datasheets to ensure compatibility with required termination materials and moisture sensitivity levels. Confirm RoHS compliance status directly with the manufacturer or authorized distributors prior to procurement. Cross-reference the full part number to validate packaging options and availability constraints.
Selection Notes
Select this component when high ripple current capacity and low equivalent series inductance are critical requirements. The 1812 footprint offers a balance between capacitance density and thermal dissipation. Ensure the circuit environment remains within the specified -55°C to +125°C operating range to maintain dielectric stability and prevent premature failure.
Part Context
This component belongs to the Knowles Syfer FlexiCap family, which specializes in high-reliability MLCCs. The 'Y' designation indicates the 1812 case size, while '100' specifies the 100V DC rating. The '204' code denotes the 0.2 µF capacitance value. This series is engineered for demanding industrial and automotive environments requiring robust electrical performance.
Replacement Considerations
Consult official substitution guides for compatible equivalents. Verify that any alternative maintains identical pass-through functionality and current ratings.
