1206J2000182MXTE03

Overview

The Knowles Syfer 1206J2000182MXTE03 is a feed-through multilayer ceramic capacitor designed for surface mount technology. It features a capacitance of 1800 pF with a DC voltage rating of 200 V and a maximum current handling capacity of 50 mA. The component utilizes an X7R dielectric material, providing stable performance across a temperature range of -55°C to +125°C. Housed in a standard 1206 (3216 metric) package, it incorporates a nickel barrier and 100% tin termination system. This device integrates filtering capabilities directly into the passive component structure.

Feature Summary

• Integrates feed-through filtering functionality within a standard surface-mount footprint
• Supports high continuous current loads up to 50 mA without degradation
• Utilizes X7R dielectric for reliable capacitance stability under thermal stress
• Features nickel barrier terminations compatible with standard reflow soldering processes

Applications

• Power supply input/output filtering for noise suppression
• EMI/RFI mitigation in compact electronic assemblies
• Signal conditioning in high-current DC circuits
• Board-level filtering for sensitive analog or digital interfaces

Procurement Notes

Verify the specific suffix MXTE03 against official Knowles Syfer documentation to confirm the presence of the feed-through architecture and terminal configuration. Ensure that the 50 mA current rating aligns with the operational requirements of the target circuit. Confirm RoHS compliance status through the manufacturer's latest environmental declarations before integration.

Selection Notes

Select this component when board space constraints require combined decoupling and filtering functions. The 1206 package allows for automated placement while maintaining high current capability. Consider the X7R temperature coefficient if operating conditions involve significant thermal variations. Validate that the 200 VDC rating exceeds the peak circuit voltages to ensure long-term reliability.

Part Context

This part belongs to the Knowles Syfer feed-through capacitor series, which merges passive filtering with standard MLCC form factors. Unlike traditional discrete filters, these components reduce component count and parasitic inductance. The 1206 size offers a balance between current handling capacity and PCB real estate efficiency for modern high-density designs.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Verify compatibility with alternative feed-through capacitors by matching the 1800 pF capacitance, 200 VDC rating, 50 mA current limit, and 1206 package dimensions.
