1806J0250473MJTE07

Overview

The Knowles Syfer 1806J0250473MJTE07 is a surface-mount feed-through capacitor designed for high-frequency noise suppression. It features a 0.047 µF capacitance with ±20% tolerance and an X7R dielectric, rated for 25 VDC. The component operates within a temperature range of -55°C to +125°C. It utilizes a three-terminal architecture with nickel barrier and tin termination, housed in a compact 1806 (4516 metric) package. This design supports efficient electromagnetic interference filtering in space-constrained applications.

Feature Summary

• Three-terminal feed-through architecture provides superior high-frequency noise attenuation compared to standard two-terminal capacitors.
• Nickel barrier and tin termination structure ensures reliable solderability and robust mechanical integrity during surface mount assembly.
• X7R dielectric material maintains stable capacitance performance across the full industrial operating temperature range.

Applications

• High-speed digital signal line filtering
• Power supply input/output decoupling
• Electromagnetic interference suppression in communication equipment

Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to confirm terminal configuration and packaging type. Ensure the selected variant matches the required voltage rating and capacitance tolerance for the target circuit. Cross-reference the RoHS compliance status and lead time requirements with authorized distributors prior to finalizing procurement orders.

Selection Notes

Select this component when high-frequency noise suppression is critical and board space is limited. The three-terminal design offers lower parasitic inductance than standard MLCCs. Verify that the 25V DC rating exceeds the maximum circuit voltage. Confirm compatibility with automated pick-and-place processes due to the standard 1806 footprint dimensions.
