4400-040LF

Overview

The Tusonix 4400-040LF is an axial feedthrough capacitor rated at 27,000 pF (0.027 µF) with a 50 V DC voltage rating. It supports a maximum current of 10 A and operates within a temperature range of -55°C to +125°C. The component features a threaded bushing package with 4-40 UNC-2A thread specifications. Physical dimensions are approximately 0.125 inches in diameter and 0.6 inches in length. This part belongs to the 4400 series of EMI feedthrough filters.

Feature Summary

• Provides high-capacitance EMI suppression through a single-feedthrough design
• Supports high continuous current loads up to 10 A
• Maintains stable electrical performance across extreme temperature environments

Applications

• Power supply input filtering for electronic equipment
• EMI suppression in high-current DC distribution lines
• Signal conditioning in industrial control systems

Procurement Notes

Verify the specific suffix LF indicates lead-free compliance against manufacturer documentation. Confirm thread size and physical dimensions match panel cutout requirements. Check RoHS status as variations may exist within the series. Ensure the 50V rating meets circuit voltage peaks. Validate current handling capabilities for the intended load.

Selection Notes

Select this component when high capacitance is required for low-frequency noise attenuation in power lines. The 50V rating suits lower voltage DC applications compared to higher-rated variants. Consider the axial bushing form factor for direct panel mounting. Compare insertion loss characteristics if high-frequency performance is critical alongside bulk capacitance.

Part Context

This component is part of the Tusonix 4400 series, which specializes in axial feedthrough capacitors. These filters are designed for chassis mounting to provide effective electromagnetic interference shielding. The series offers various capacitance and voltage ratings to suit different power line filtering needs.
