1812Y0250185MXTE07

Overview

The Knowles Syfer 1812Y0250185MXTE07 is a feed-through capacitor housed in an 1812 (4532 metric) surface-mount package. It features a capacitance of 1.8 µF with a voltage rating of 25 VDC and a current rating of 2 A. The component utilizes X7R dielectric material, providing stable performance across a temperature range of -55°C to +125°C. It offers a tolerance of ±20% and includes integrated EMI filtering capabilities for high-frequency noise suppression.

Feature Summary

• Integrated electromagnetic interference (EMI) filtering within the passive component structure
• High current handling capability suitable for power line applications
• Surface-mount design optimized for automated assembly processes

Applications

• Power supply input filtering
• Data line noise suppression
• General EMI suppression in compact electronics

Procurement Notes

Verify the specific suffix configuration against official manufacturer documentation to ensure correct electrical ratings and termination specifications. Confirm RoHS compliance status and lead times directly with authorized distributors prior to ordering. Ensure compatibility with standard reflow soldering profiles for this component type.

Selection Notes

Select this component when space-constrained designs require combined decoupling and EMI filtering functions. The 1812 footprint allows for higher capacitance density compared to smaller packages. Evaluate thermal management requirements as the component handles significant current flow during operation.

Part Context

This part belongs to the Knowles Syfer feed-through capacitor series, designed to replace traditional discrete filter components. These devices integrate capacitive elements directly into the terminal structure, reducing board space and parasitic inductance associated with external filter circuits.
