4400-037

Overview

The 4400-037 is a feedthrough capacitor manufactured by Tusonix, a subsidiary of CTS Electronic Components. It features a capacitance of 1000 pF with a rated voltage of 200V and a current rating of 10 A. The component utilizes an axial, bushing package configuration. Its physical dimensions are specified as 0.157 inches in diameter by 0.276 inches in length (4.00 mm x 7.00 mm). The device operates within a temperature range of -55°C to +125°C and provides an insertion loss of 20 dB at 100 MHz.

Feature Summary

• Provides electromagnetic interference suppression through feedthrough filtering architecture
• Supports high current handling capabilities for power line applications
• Designed for robust operation across extended industrial temperature ranges

Applications

• Electromagnetic interference filtering in electronic systems
• Power supply input stages requiring high-voltage isolation
• Industrial equipment signal conditioning

Procurement Notes

Verify the specific RoHS compliance status, as non-LF variants may not meet current environmental directives. Confirm that the axial bushing mounting style aligns with panel cutout requirements. Ensure the 200V rating and 10A current capacity exceed circuit maximums. Validate thermal performance under continuous load conditions within the specified operating temperature range.

Selection Notes

Select this component when axial feedthrough topology is required for direct panel mounting. Compare against the 4400-037LF variant if lead-free compliance is mandatory. Evaluate the 1000 pF capacitance value against circuit filtering needs. Consider the 200V rating for higher voltage bus applications compared to lower-rated series members.

Part Context

This part belongs to the 4400 series of EMI feedthrough filters from Tusonix/CTS. The series offers various capacitance values and voltage ratings in axial bushing packages. These components are designed for chassis-mounted installation to provide effective noise attenuation in sensitive electronic environments.

Replacement Considerations

The 4400-037LF serves as the lead-free compliant alternative within the same product family. Verify mechanical compatibility before substitution.
