1812J1000404MXTE07

Overview

The Knowles Syfer 1812J1000404MXTE07 is a feed-through capacitor designed for surface mount technology. It features a capacitance of 0.4 µF and operates at a rated DC voltage of 100 VDC. The component supports a continuous current of 50 mA and utilizes an 1812 (4532 metric) package footprint. This device integrates filtering capabilities directly into the circuit layout, offering a compact solution for high-frequency noise suppression in electronic assemblies.

Feature Summary

• Integrates feed-through filtering functionality within a standard surface-mount package
• Supports continuous current handling up to 50 mA for power line applications
• Utilizes X7R dielectric material for stable performance across operating temperatures

Applications

• High-frequency noise suppression in power supply lines
• EMI filtering in compact electronic modules
• Signal integrity protection in sensitive circuit interfaces

Procurement Notes

Verify the specific suffix 'E07' against official manufacturer documentation to confirm packaging or tape-and-reel specifications. Ensure the selected variant matches the required 50 mA current rating and 100 VDC voltage tolerance for the target application environment. Cross-reference the datasheet for precise dimensional tolerances and soldering profile requirements.

Selection Notes

Select this component when space-constrained designs require integrated feed-through filtering without additional discrete components. Confirm that the 1812 footprint aligns with the PCB layout constraints. Evaluate the 50 mA current capacity against peak load requirements to prevent thermal issues. Verify compatibility with the assembly process regarding the specific termination style and reflow temperature limits defined in the product specification.

Part Context

This part belongs to the Knowles Syfer MLCC series, specifically engineered for high-reliability applications. The 1812J prefix indicates the 1812 case size and general construction type. As a feed-through capacitor, it differs from standard parallel-plate MLCCs by providing a direct path for current while shunting high-frequency interference to ground, making it suitable for stringent EMI/EMC compliance needs.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Consult the manufacturer's official substitution guide or contact technical support for verified equivalents that match the 0.4 µF capacitance, 100 VDC rating, and 50 mA current handling capability.
