1812J2000183MXTE03

Overview

The Knowles Syfer 1812J2000183MXTE03 is a feed-through capacitor with a capacitance of 0.018 µF and a voltage rating of 200V DC. It operates within a temperature range of -55°C to +125°C and features a 1812 (4532 metric) package size. The component supports a maximum current of 50 mA and utilizes a three-pad configuration for surface mount technology.

Feature Summary

• Integrates feed-through functionality for effective noise suppression in high-frequency circuits
• Supports continuous current flow up to 50 mA without performance degradation
• Utilizes a robust three-pad surface mount design for enhanced mechanical stability

Applications

• High-frequency signal filtering in communication systems
• Power line noise suppression in sensitive electronic equipment
• EMI/RFI mitigation in compact circuit board designs

Procurement Notes

Verify the specific lead times and availability directly with authorized distributors, as stock levels for specialized feed-through components can fluctuate. Confirm that the three-pad footprint matches your PCB layout requirements precisely. Ensure compliance with RoHS directives if required by your manufacturing standards. Cross-reference the datasheet for any recent product change notifications or environmental compliance updates before finalizing procurement orders.

Selection Notes

Select this component when both signal transmission and noise filtering are required in a single device. The 200V rating suits low-voltage DC applications, while the 50mA current capacity defines its power handling limits. Compare against standard MLCCs if isolation or through-hole mounting is not feasible. Consider the 1812 package dimensions for space-constrained layouts requiring integrated filtering solutions.

Part Context

This part belongs to the Knowles Syfer feed-through capacitor series, designed for applications demanding superior electromagnetic interference suppression. Unlike standard multilayer ceramic capacitors, these components integrate a conductive path, allowing signals to pass while shunting noise to ground. The XT designation typically indicates specific material properties optimized for reliability in harsh environments.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Engineers should consult the manufacturer's official substitution guide or contact technical support for validated equivalents. Verify that any alternative component matches the 50mA current rating and 200V DC specification to ensure circuit integrity.
