1812J1000204MJTE03

Overview

The Knowles Syfer 1812J1000204MJTE03 is a feed-through capacitor designed for high-frequency noise suppression. It features a capacitance of 0.2 µF with a voltage rating of 100 VDC and a current rating of 50 mA. The component utilizes an 1812 (4532 metric) surface-mount package with three PC pads. This configuration integrates filtering capabilities directly into the circuit layout, offering compact signal conditioning for sensitive electronic applications.

Feature Summary

• Integrates feed-through filtering functionality within a standard surface-mount footprint
• Provides simultaneous electrical connection and high-frequency noise attenuation
• Utilizes a three-pad terminal structure for direct PCB integration

Applications

• High-speed digital signal line filtering
• RF interference suppression in communication modules
• Power distribution noise reduction in compact electronics

Procurement Notes

Verify the specific current rating of 50 mA against operational requirements to prevent thermal issues. Confirm the 100 VDC rating aligns with peak circuit voltages. Ensure the 1812 footprint matches the target PCB design. Check for RoHS compliance documentation if required by project specifications.

Selection Notes

Select this component when space constraints prohibit discrete filter components. The integrated feed-through design simplifies layout compared to traditional LC filters. Consider the 50 mA limit for continuous current loads. Evaluate the trade-off between insertion loss and physical size for the specific frequency range of interest.

Part Context

This part belongs to the Knowles Syfer feed-through capacitor series, which combines passive filtering with interconnect functions. Unlike standard MLCCs, these components are engineered to attenuate common-mode and differential-mode noise while maintaining signal integrity in dense board layouts.
