The component operates within a temperature range of -55°C to +125°C and has a current rating of 300 mA. Its maximum DC resistance is 600 mOhms, and insulation resistance is 1 GOhm. The package is 0805 (2012 metric) with four terminals.

Feature Summary

• Three-terminal feedthrough architecture for effective electromagnetic interference filtering
• High current handling capability suitable for power line applications
• Surface mount design compatible with automated assembly processes

Applications

• Smart meter power supply filtering
• Industrial control system noise suppression
• Telecommunications equipment EMI reduction

Procurement Notes

Verify the specific suffix 'T1A' corresponds to the required packaging format, such as cut tape or reel, as indicated in distributor listings. Confirm that the 0805 footprint matches the target PCB layout. Ensure the 300 mA current rating meets the circuit requirements. Check RoHS compliance status if restricted substances are a constraint. Validate the manufacturer part number against official KYOCERA AVX documentation before ordering.

Selection Notes

Select this component when high-frequency noise attenuation is required on low-voltage DC lines. The three-terminal design offers superior performance compared to standard two-terminal capacitors by minimizing lead inductance. Consider the 0805 size for space-constrained boards. The X7R dielectric provides stable capacitance over the specified temperature range. Evaluate the 600 mOhm DCR to ensure minimal voltage drop in the application.

Part Context

This part belongs to the W2F series of surface-mount feedthrough capacitors. These components are designed for general-purpose EMI filtering in compact electronic devices. The series utilizes ceramic technology to provide reliable performance in harsh environments. The W2F designation distinguishes it from other KYOCERA AVX filter families based on terminal configuration and mounting style.

Replacement Considerations

Publicly confirmed substitutes include W2F15C4738AT1F and W2F15C4738AT3A. Verify pin compatibility and electrical parameters before substitution.
