1812J5000472MJTE03

Overview

The Knowles Syfer 1812J5000472MJTE03 is a feed-through capacitor designed for surface-mount applications. It features a capacitance of 4700 pF with a DC voltage rating of 500 V. The component utilizes an X7R dielectric material and maintains a tolerance of ±20%. Housed in a 1812 (4532 metric) package, it supports a maximum current of 50 mA. The device operates within a temperature range of -55°C to +125°C.

Feature Summary

• Integrates feed-through architecture for effective electromagnetic interference suppression
• Supports high current handling capability up to 50 mA
• Utilizes X7R ceramic dielectric for stable performance across operating temperatures

Applications

• Electromagnetic interference filtering in electronic circuits
• Power supply input stages requiring high current handling
• Signal line protection in sensitive electronic systems

Procurement Notes

Verify the specific suffix JTE03 against official manufacturer documentation to confirm pin configuration and termination style. Ensure compatibility with PCB pad layouts designed for feed-through components. Cross-reference the 50 mA current rating with circuit requirements to prevent thermal issues during operation.

Selection Notes

Select this component when board space constraints require a surface-mount solution for high-current filtering. The 1812 footprint offers a balance between current capacity and size. Consider the X7R dielectric characteristics for applications where moderate capacitance stability is sufficient compared to C0G/NP0 types.

Part Context

This part belongs to the Knowles Syfer feed-through capacitor series, distinct from standard multilayer ceramic capacitors. These components integrate the capacitor element directly into the conductor path, providing superior high-frequency noise attenuation. The 1812J series specifically targets applications requiring robust surface-mount filtering solutions.
