4400-041LF

Overview

The Tusonix 4400-041LF is a feed-through capacitor rated at 50V with a capacitance of 50,000 µF. It supports a current of 10 A and operates within a temperature range of -55°C to +125°C. The component features an axial package with a threaded M3x0.5 specification. It provides an insertion loss of 45dB at 100MHz. The unit measures 0.157 inches in diameter by 0.276 inches in length.

Feature Summary

• Provides high-capacitance EMI suppression through feed-through architecture
• Supports panel mounting via integrated nut and lock washer
• Operates reliably across extended industrial temperature ranges

Applications

• Power supply input filtering for electronic equipment
• EMI suppression in DC power distribution lines
• Panel-mounted filter installations requiring high current handling

Procurement Notes

Verify the specific suffix designation against official datasheets to confirm compliance status, as non-LF variants may differ in material composition. Confirm mechanical dimensions and threading specifications match the intended panel cutout requirements before procurement. Ensure the operating voltage and current ratings align with the system's maximum load conditions to prevent component failure.

Selection Notes

Select this component when high capacitance values are required for low-frequency noise attenuation in power lines. The axial leaded design facilitates easy integration into chassis-mounted applications. Consider the physical size constraints and available panel space for the threaded mounting hardware during the initial design phase.

Part Context

This part belongs to the 4400 series of feed-through capacitors manufactured by Tusonix, a subsidiary of CTS Electronic Components. The series is designed for robust EMI filtering in demanding environments. The LF suffix typically indicates lead-free compliance, distinguishing it from older non-compliant versions within the same electrical specification family.

Replacement Considerations

Direct substitutes include the 4400-041 variant, though verification of RoHS compliance is necessary. Cross-reference mechanical dimensions and terminal configurations to ensure compatibility with existing panel mounts.
