Overview
The Knowles Syfer 1812J1000184MJTE03 is a feed-through capacitor with a capacitance of 0.18 µF and a rated voltage of 100 VDC. It features a maximum current rating of 50 mA and utilizes an 1812 (4532 metric) package footprint designed for three-pad mounting. This component integrates high-frequency noise suppression directly into the circuit path, combining filtering capabilities with structural stability for surface-mount applications requiring compact form factors.
Feature Summary
- Integrates feed-through filtering functionality within a standard surface-mount footprint
- Supports direct signal line integration with specified current handling capability
- Designed for high-frequency noise attenuation in compact electronic assemblies
Applications
- High-frequency noise suppression in signal lines
- Compact EMI/RFI filtering solutions
- Space-constrained power or data interface circuits
Procurement Notes
Verify the specific pin configuration and pad layout against the official datasheet to ensure compatibility with the target PCB footprint. Confirm that the operating current does not exceed the 50 mA rating during peak conditions. Check for any specific handling requirements related to the ceramic construction and soldering profile recommended by the manufacturer.
Selection Notes
Select this component when a combined feed-through filter and surface-mount convenience is required. The 1812 package offers a balance between size and performance. Ensure the 100 VDC rating and 50 mA current limit align with the circuit's operational parameters. Consider the thermal management implications of the integrated design compared to discrete components.
Part Context
This part belongs to the Knowles Syfer feed-through capacitor series, which merges filtering elements with mechanical mounting structures. These components are distinct from standard MLCCs as they allow current to pass through the device while attenuating unwanted frequencies. The 1812J series indicates the specific case size and voltage class within the broader product portfolio.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Verify electrical equivalence and physical dimensions before considering alternative manufacturers.
