1812J1000683MJTE03

Overview

The Knowles Syfer 1812J1000683MJTE03 is a feed-through capacitor designed for surface mount technology. It features a capacitance of 0.068 µF with a rated voltage of 100V DC and a current rating of 50 mA. The component utilizes an X7R dielectric material housed in a 1812 (4532 metric) package. It operates within a temperature range of -55°C to +125°C and includes a three-pad footprint configuration.

Feature Summary

• Integrates feed-through architecture for direct signal path integration
• Provides electromagnetic interference filtering capabilities
• Supports high-current handling up to 50 mA
• Utilizes X7R dielectric for stable performance across operating temperatures

Applications

• High-frequency signal line filtering
• Power supply input/output decoupling
• Electromagnetic interference suppression in sensitive circuits

Procurement Notes

Verify the specific pinout and pad layout requirements against your PCB design, as this is a feed-through component requiring a three-terminal connection. Confirm that the 50 mA current rating meets your application's peak load demands. Ensure the 100V DC rating provides sufficient margin for your circuit's maximum operating voltage. Check for RoHS compliance documentation if required by your manufacturing standards.

Selection Notes

Select this component when integrated EMI filtering is required without adding discrete series inductors. The feed-through design minimizes parasitic inductance compared to standard MLCCs. Consider the 1812 package size constraints and the need for three solder pads. Evaluate the X7R temperature coefficient stability against your environmental conditions.

Part Context

This part belongs to the Knowles Syfer feed-through capacitor series, distinct from standard multilayer ceramic capacitors. It combines capacitance with a conductive center terminal, allowing it to pass current while shunting noise to ground. This form factor is critical for applications where space is limited and low-inductance filtering is essential.
