1206J1000182MXTE01

Overview

The Knowles Syfer 1206J1000182MXTE01 is a surface-mount feedthrough capacitor designed for EMI suppression. It features a capacitance of 1800 pF with a ±20% tolerance, rated for 100 VDC. The component utilizes X7R dielectric material and operates within a temperature range of -55°C to +125°C. Housed in a standard 1206 (3216 metric) package, it includes an integrated nickel barrier termination structure. This design supports high-frequency noise filtering applications while maintaining mechanical stability under thermal cycling conditions.

Feature Summary

• Integrated nickel barrier termination structure enhances reliability and solderability
• Feedthrough architecture provides effective electromagnetic interference suppression
• X7R dielectric ensures stable capacitance performance across wide temperature ranges

Applications

• High-frequency signal line filtering
• Power supply input/output noise reduction
• EMI suppression in sensitive electronic circuits

Procurement Notes

Verify the complete part number including the E01 suffix to confirm the specific feedthrough variant and termination type. Ensure compatibility with existing PCB footprint dimensions for the 1206 package. Confirm RoHS compliance status through official manufacturer documentation prior to integration into production assemblies.

Selection Notes

Select this component when space-constrained EMI filtering is required in 1206 form factors. The X7R dielectric offers higher capacitance density compared to C0G types, suitable for general-purpose filtering where strict stability is less critical than volume efficiency. Verify voltage derating requirements for the specific application environment.

Part Context

This component belongs to the Knowles Syfer E01 series of surface-mount feedthrough capacitors. These devices are engineered specifically for compact EMI filter designs, combining capacitor functionality with shielding characteristics in a single SMD package. The series targets applications demanding robust noise attenuation in limited board real estate.

Replacement Considerations

Direct substitutes include other 1206 feedthrough capacitors from Knowles Syfer such as 1206J1000102MCTE01 or 1206J1000472MXTE01, provided capacitance values align with circuit requirements. Cross-brand replacements require verification of equivalent impedance characteristics and physical footprint compatibility.
