Overview
The Knowles Syfer 1812J5000822MXTE03 is a feed-through multilayer ceramic capacitor designed for surface-mount applications. It features an 8200 pF capacitance with a 500 VDC voltage rating and supports a continuous current of 50 mA. The component utilizes a 1812 (4532 metric) package footprint, ensuring compatibility with standard high-density board layouts while providing robust electrical performance in compact form factors.
Feature Summary
- Integrates feed-through architecture to provide effective electromagnetic interference suppression within the circuit path
- Supports continuous current flow of 50 mA without compromising dielectric integrity or signal stability
- Utilizes X7R dielectric material to maintain stable capacitance characteristics across varying temperature conditions
Applications
- High-frequency signal filtering in communication equipment
- Power line noise suppression in automotive electronics
- EMI mitigation in industrial control systems
Procurement Notes
Verify the specific suffix MXTE03 against official manufacturer documentation to confirm terminal configuration and packaging details. Ensure design compatibility with 50 mA continuous current requirements. Cross-reference RoHS compliance status with current regulatory standards before integration into final assemblies.
Selection Notes
Select this component when simultaneous DC power transmission and RF noise attenuation are required in a single surface-mount device. The 1812 package offers a balance between current handling capability and board space efficiency compared to smaller footprints.
Part Context
This part belongs to the Knowles Syfer feed-through capacitor series, which combines passive filtering with active circuit connectivity. Unlike standard MLCCs, these components allow current to pass through the center conductor while shunting high-frequency noise to ground, serving as integrated bypass elements.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source data. Verify pinout and current ratings carefully if considering alternative manufacturers.
