1812J2000683MXTE03

Overview

The Knowles Syfer 1812J2000683MXTE03 is a surface-mount feed-through capacitor designed for high-frequency noise suppression. It features a capacitance of 0.068 µF and a DC voltage rating of 200 V. The component utilizes X7R dielectric material and operates within a temperature range of -55°C to +125°C. Housed in an 1812 (4532 metric) package with three PCB pads, it supports a maximum current of 50 mA.

Feature Summary

• Integrates feed-through architecture for effective electromagnetic interference attenuation
• Utilizes X7R ceramic dielectric for stable performance across wide temperature ranges
• Supports surface-mount assembly via standard three-pad footprint configuration

Applications

• High-frequency noise filtering in power supply lines
• Electromagnetic interference suppression in sensitive electronic circuits
• Signal integrity protection in communication equipment

Procurement Notes

Verify the specific suffix MXTE03 against official Knowles Syfer documentation to confirm packaging and termination specifications. Ensure compatibility with existing board layouts regarding the three-pad footprint. Confirm RoHS compliance status through current manufacturer declarations before integration into production schedules.

Selection Notes

Select this component when a compact solution is required for attenuating high-frequency noise on low-current lines up to 50 mA. The 200 V rating provides sufficient margin for many low-voltage applications. Consider the 1812 footprint constraints and thermal management requirements associated with X7R dielectrics during circuit design.

Part Context

This part belongs to the Knowles Syfer family of feed-through capacitors, which are engineered for superior high-frequency performance compared to standard MLCCs. The 1812J series designation indicates the case size and voltage class, while the specific model number defines the capacitance value and termination style for surface-mount integration.
