W2F15C4738AT3A

Overview

The KYOCERA AVX W2F15C4738AT3A is a surface-mount feed-through capacitor with a capacitance of 0.047 µF and a DC voltage rating of 50 VDC. It utilizes X7R dielectric material and features a tolerance range of -20% to +50%. The component operates within a temperature range of -55°C to +125°C and has a maximum DC resistance of 600 mOhms. It is housed in an 0805 (2012 metric) package measuring 2.01 mm in length, 1.25 mm in width, and 1.14 mm in height. The device supports a current rating of 300 mA and includes four terminals for mounting.

Feature Summary

• Provides electromagnetic interference filtering through three-terminal feed-through architecture
• Offers stable capacitance performance across wide temperature variations using X7R dielectric
• Enables compact circuit design via standard 0805 surface-mount footprint

Applications

• Smart meter applications
• General electronic circuit filtering
• Power supply noise suppression

Procurement Notes

Verify the specific ordering suffix AT3A against the manufacturer datasheet to confirm packaging configuration. Ensure compatibility with automated pick-and-place equipment regarding the 0805 package dimensions. Confirm that the -20% to +50% tolerance aligns with circuit requirements. Check RoHS compliance status if restricted substances are mandated by project specifications.

Selection Notes

Select this component when space-constrained designs require high-frequency filtering capabilities. The 0805 package size suits applications needing moderate capacitance without occupying excessive board area. Consider the 300 mA current rating and 600 mOhm resistance for power integrity needs. Verify that the 50 VDC rating exceeds the maximum operating voltage in the target application environment.
