1812Y0500474MJTE03

Overview

The Knowles Syfer 1812Y0500474MJTE03 is a feed-through multilayer ceramic capacitor in an 1812 (4532 metric) surface-mount package. It features a capacitance of 0.47 µF with a ±20% tolerance and a DC voltage rating of 50 VDC. The component utilizes X7R dielectric material and is designed for high-current applications, supporting up to 50 mA. It incorporates FlexiCap technology with a nickel barrier and tin termination system to enhance mechanical reliability.

Feature Summary

• Integrated feed-through architecture for efficient power line filtering
• FlexiCap flexible terminations to mitigate board flex stress
• Nickel barrier plating structure for enhanced solderability

Applications

• High-current power distribution networks
• Board-level decoupling for sensitive integrated circuits
• Automotive electronics requiring AEC-Q200 compliance

Procurement Notes

Verify the complete part number including the suffix to ensure correct termination and packaging specifications. Confirm that the 50 mA current rating aligns with the target circuit requirements. Check for RoHS3 compliance status and ensure the 1812 footprint matches the design layout constraints before finalizing procurement.

Selection Notes

Select this component when high ripple current handling is required alongside standard decoupling functions. The feed-through design offers superior performance compared to standard MLCCs in noisy environments. Ensure the operating temperature range of -55°C to +125°C meets the application's thermal conditions.

Part Context

This component belongs to the Knowles Syfer Y-series, which specializes in high-reliability capacitors for demanding environments. The series emphasizes robust construction and consistent electrical performance across wide temperature ranges, targeting industrial and automotive sectors where failure rates must be minimized.

Replacement Considerations

Direct substitutes require matching the 1812 footprint, 0.47 µF capacitance, 50 V rating, and feed-through topology. Verify that alternative components support the 50 mA current rating and possess compatible termination structures to maintain mechanical integrity.
