Overview
The Knowles Syfer 1806Y0250394MXTE07 is a surface-mount multilayer ceramic capacitor (MLCC) designed for general-purpose applications. It features a 1806 (4516 metric) case size with a capacitance of 0.39 µF and a DC voltage rating of 25 VDC. The component utilizes X7R dielectric material, providing stable performance across a temperature range of -55°C to +125°C. Tolerance is specified at ±20%. This device is packaged in reels for automated assembly processes.
Feature Summary
- Utilizes X7R dielectric material for reliable capacitance stability over a wide operating temperature range.
Applications
- General-purpose electronic circuits requiring standard decoupling or filtering.
Procurement Notes
Verify the specific datasheet version and RoHS compliance status directly with the manufacturer or authorized distributor before procurement. Confirm that the reel packaging quantity matches your production line requirements. Ensure the 1806 footprint dimensions align precisely with your PCB layout design to prevent mounting issues during assembly.
Selection Notes
Select this component when a 0.39 µF capacitance value is required within a compact 1806 package. The X7R dielectric offers a balance between cost and performance for general applications. Verify that the 25 VDC rating provides sufficient margin for the circuit's maximum operating voltage. Consider thermal constraints as the component operates up to +125°C.
