SFAJC5000100ZC1

Overview

The SFAJC5000100ZC1 is a Knowles Syfer feed-through capacitor designed for EMI filtering applications. It features a capacitance of 10 pF with a tolerance of -20% to +80%. The component has a DC voltage rating of 500 VDC and utilizes an X7R dielectric material. It supports a maximum DC current of 10 A and operates within a temperature range of -55°C to +125°C. The device employs a solder termination type and includes two terminals. Physical dimensions include a diameter of 4 mm, a length of 9.2 mm, and a lead wire diameter of 0.7 mm. The package is supplied in bulk quantities.

Feature Summary

• Provides electromagnetic interference (EMI) suppression through feed-through capacitor architecture
• Utilizes X7R dielectric material for stable electrical performance across operating temperatures
• Features bushing mounting configuration with axial leads for panel installation

Applications

• Electronic equipment requiring EMI filtering
• Power supply input/output stages
• Signal line protection circuits

Procurement Notes

Verify the specific tolerance band (-20%, +80%) against circuit requirements, as it differs from standard symmetric tolerances. Confirm that the X7R dielectric meets the stability needs of the application, particularly regarding capacitance drift under varying conditions. Ensure the 500 VDC rating aligns with the system's peak voltage stresses. Check lead wire diameter compatibility with existing panel holes or connectors.

Selection Notes

Select this component when a compact feed-through filter is required for moderate capacitance values. The 10 pF value suits high-frequency noise attenuation where minimal signal loading is necessary. Consider the X7R dielectric if cost-effective stability is preferred over C0G/NP0 precision. Verify that the 10 A current rating exceeds the maximum expected load current to prevent thermal issues. Ensure the physical size fits the designated enclosure space.
