1812J1000822MJTE03

Overview

The Knowles Syfer 1812J1000822MJTE03 is a feed-through multilayer ceramic capacitor designed for high-frequency noise suppression. It features an 8200 pF capacitance with a 100 VDC rating and operates within a -55°C to +125°C temperature range. The component utilizes C0G/NP0 dielectric material for stable performance. It is housed in a 1812 (4532 metric) surface-mount package with three PC pads, supporting a continuous current of 50 mA.

Feature Summary

• Integrated feed-through architecture combining filtering and mounting functions
• Three-pad surface mount design for enhanced mechanical stability
• C0G/NP0 dielectric ensures minimal capacitance variation over temperature

Applications

• High-frequency EMI/RFI noise suppression in sensitive circuits
• Power line filtering for DC voltage rails
• Signal integrity protection in automotive electronics

Procurement Notes

Verify the specific suffix MJTE03 against official datasheets to confirm the feed-through configuration and terminal type. Ensure compatibility with PCB pad layouts requiring three distinct connection points. Confirm RoHS compliance status through manufacturer documentation prior to integration into regulated assemblies.

Selection Notes

Select this component when board space constraints require combined filtering and termination functions. The 1812 footprint offers a balance between capacitance density and thermal management. Verify that the 50 mA current rating exceeds the maximum expected load current in the target application circuit to prevent device failure.

Part Context

This part belongs to the Knowles Syfer feed-through capacitor series, which integrates capacitive elements directly into the mounting structure. Unlike standard MLCCs, these components provide superior high-frequency attenuation by minimizing parasitic inductance associated with traditional leaded or two-terminal surface mount designs.

Replacement Considerations

Direct substitutes must match the 1812 footprint, 8200 pF value, 100V rating, and specifically the three-pad feed-through topology. Standard two-terminal MLCCs are not functionally equivalent due to differences in parasitic inductance and mounting requirements.
