M15733/43-0002

Overview

The M15733/43-0002 is an EMI feedthrough filter manufactured by Tusonix, a subsidiary of CTS Electronic Components. It belongs to the MIL-DTL-15733 series and utilizes a Pi filter circuit topology. The component features a capacitance of 1500 pF and a voltage rating of 100 V at 125°C. It employs an 8-32 UNC-2A thread size for chassis mounting. The device is designed for high-frequency noise suppression in electronic systems.

Feature Summary

• Provides effective electromagnetic interference attenuation through integrated LC filtering stages
• Features robust threaded chassis mount design for secure installation
• Utilizes low-inductance construction to maintain performance at high frequencies

Applications

• Military and aerospace electronic equipment requiring MIL-DTL-15733 compliance
• Radar and communication systems needing high-frequency noise suppression
• Power supply input/output filtering in sensitive instrumentation

Procurement Notes

Verify the manufacturer designation as Tusonix, a subsidiary of CTS, when sourcing this component. Confirm the specific MIL-DTL-15733 revision level required for your application. Ensure the 8-32 UNC-2A threading matches your panel cutout specifications. Check for RoHS compliance status if environmental regulations apply to your project.

Selection Notes

Select this part when a 1500 pF capacitance value is required for EMI suppression. The 100 V rating suits low-voltage DC or signal line applications. Consider the physical dimensions and mounting requirements associated with the 8-32 UNC-2A thread. Compare against other Pi filter configurations if higher current handling or different capacitance values are needed.

Part Context

This component is part of the MIL-DTL-15733 family of feedthrough capacitors and filters. These components are standardized for military and high-reliability industrial applications. The Pi filter configuration offers superior attenuation compared to simple feedthrough capacitors by combining capacitive and inductive elements within a single package.

Replacement Considerations

Cross-reference tools indicate parametrically similar parts within the Tusonix and CTS portfolios. Verify exact capacitance, voltage rating, and thread compatibility before substitution. Ensure any replacement meets the same MIL-DTL-15733 specification requirements.
