1206J0250183MXTE01

Overview

The Knowles Syfer 1206J0250183MXTE01 is a surface-mount EMI filter capacitor in a 1206 (3216 metric) package. It features an X7R dielectric with a capacitance of 18 nF and a DC voltage rating of 25 VDC. The component has a tolerance of ±20% and utilizes nickel barrier end terminations with 100% tin plating. It operates within a temperature range of -55°C to +125°C and is RoHS compliant.

Feature Summary

• Integrated three-terminal feedthrough architecture for enhanced high-frequency noise suppression
• Nickel barrier termination system with 100% tin plating for reliable solderability
• X7R ceramic dielectric providing stable capacitance across the operating temperature range

Applications

• High-speed digital signal line filtering
• Power supply input/output decoupling
• EMI suppression in compact electronic modules

Procurement Notes

Verify the complete part number including the suffix to ensure correct termination and packaging specifications. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Cross-reference the datasheet for specific footprint dimensions and recommended reflow soldering profiles to prevent mechanical stress during manufacturing.

Selection Notes

Select this component when space-constrained designs require integrated filtering capabilities without additional discrete components. The 1206 form factor balances current handling capacity with board real estate efficiency. Ensure the 25V rating exceeds the maximum circuit voltage and consider the thermal environment to maintain X7R performance stability under operational loads.

Part Context

This component belongs to the Knowles Syfer 1206J series of SMT EMI filters. These devices are engineered to replace traditional LC networks by combining capacitance and shielding in a single monolithic structure. The series offers various capacitance values and voltage ratings optimized for modern high-density PCB layouts requiring robust electromagnetic interference mitigation.

Replacement Considerations

Direct substitutes must match the 1206 footprint, 18nF capacitance, 25V rating, and three-terminal feedthrough topology. Verify that alternative parts support the same nickel barrier termination style and meet identical temperature and RoHS standards.
