4403-033LF

Overview

The 4403-033LF is a feedthrough capacitor from the Tusonix 4403 series, designed for EMI suppression. It features a capacitance of 2700 pF with a tolerance of -20% to +80%. Rated at 100 V and capable of handling 10 A current, it operates within a temperature range of -55°C to 125°C. The component utilizes an axial bushing package with 4-40 thread specifications. Dimensions are 0.125 inches in diameter by 0.215 inches in length (3.18 mm x 5.47 mm). Insertion loss is specified as 25 dB at 100 MHz.

Feature Summary

• Provides effective electromagnetic interference (EMI) and radio frequency interference (RFI) suppression through feedthrough architecture.
• Supports high current loads up to 10 A while maintaining stable performance across a wide industrial temperature range.
• Features a threaded axial bushing design for secure panel mounting and reliable electrical connections.

Applications

• EMI/RFI suppression in electronic circuits
• Power line filtering applications
• Panel-mounted filter installations requiring threaded interfaces

Procurement Notes

Verify the specific suffix requirements when ordering, as the base part number may have variations. Confirm that the 4-40 thread specification matches your panel cutout requirements. Ensure the 100 V rating and 10 A current capacity meet your circuit's operational demands. Check RoHS compliance status if required for your assembly process, as documentation indicates potential non-compliance for this specific variant.

Selection Notes

Select this component when a feedthrough capacitor with axial threading is required for panel mounting. The 2700 pF value suits specific filtering needs where higher capacitance than standard bypass capacitors is necessary. Consider the 10 A current rating for power line applications. Verify that the 4-40 thread size aligns with existing hardware or panel designs before finalizing the selection.
