1806J0250273MJTE07

Overview

The Knowles Syfer 1806J0250273MJTE07 is a surface-mount multilayer ceramic capacitor (MLCC) designed as a three-terminal EMI filter. It features a capacitance of 27 nF with a tolerance of ±20% and utilizes X7R dielectric material. The component is rated for a maximum DC voltage of 25V and operates within a temperature range of -55°C to +125°C. Housed in an 1806 (4516 metric) package, it incorporates a nickel barrier termination structure with 100% tin plating to enhance solderability and corrosion resistance.

Feature Summary

• Three-terminal architecture provides enhanced high-frequency noise attenuation compared to standard two-terminal capacitors.
• Nickel barrier termination technology ensures robust solder joints and improved reliability under thermal stress.
• X7R dielectric composition offers stable capacitance performance across the specified operating temperature range.

Applications

• High-frequency electromagnetic interference suppression in sensitive electronic circuits
• Power supply input filtering for integrated circuits requiring clean voltage rails

Procurement Notes

Verify the complete part number including the suffix to ensure correct termination and packaging specifications. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Cross-reference the datasheet for specific handling requirements related to moisture sensitivity and reflow soldering profiles to prevent component damage during assembly.

Selection Notes

Select this component when superior high-frequency noise filtration is required in space-constrained designs. The three-terminal configuration is preferred over standard MLCCs for applications demanding significant attenuation of radio frequency interference. Ensure the 25V rating aligns with the circuit's maximum operating voltage to maintain long-term reliability and prevent dielectric breakdown.
