0805J1000391MATE01

Overview

The Knowles Syfer 0805J1000391MATE01 is a feed-through capacitor designed for surface-mount technology. It features a capacitance of 390 pF with a DC voltage rating of 100 V and a current rating of 300 mA. The component utilizes an 0805 (2012 metric) package size. This specific variant is distinguished by its integrated mounting pad structure, facilitating direct PCB integration without additional discrete components.

Feature Summary

• Integrated feed-through design combining filtering and mounting functions
• Surface-mount construction for automated assembly compatibility
• High current handling capability within the specified package

Applications

• RF signal path filtering in compact modules
• Power line decoupling for high-frequency circuits
• EMI suppression in space-constrained electronic assemblies

Procurement Notes

Verify the complete part number including the MATE01 suffix to ensure correct identification of the integrated pad configuration. Confirm that the 300 mA current rating aligns with the specific circuit requirements. Check for RoHS compliance documentation if environmental regulations apply to the final product assembly.

Selection Notes

Select this component when both signal filtering and mechanical mounting are required in a single footprint. The integrated pad design reduces board space usage compared to standard MLCCs requiring separate mounting structures. Ensure the 100 V DC rating meets the maximum operating voltage of the application.

Part Context

This component belongs to the Knowles Syfer feed-through capacitor series, which integrates ceramic dielectric filtering elements with conductive mounting pads. Unlike standard multilayer ceramic capacitors, these devices provide a unified solution for noise suppression and physical attachment, optimizing layout density in high-density interconnect designs.
