CR8348-2000-D

Overview

The CR8348-2000-D is a DC immune vertical PCB current transformer from the CR8300 series by CR Magnetics Inc. Designed for non-invasive monitoring, it features a solid core construction suitable for through-hole mounting. The component operates within a frequency range of 20Hz to 1kHz and supports a rated current of 50A with a 2000:1 current ratio. It exhibits a typical DC resistance of 106 Ohms and utilizes PC pin termination for secure board integration.

Feature Summary

• DC immune design eliminates offset errors caused by direct current components
• Vertical PCB mounting configuration optimizes space on printed circuit boards
• Non-invasive solid core structure allows for safe current monitoring without circuit interruption

Applications

• Industrial motor drive systems
• Power supply output monitoring
• Battery management systems

Procurement Notes

Verify the specific suffix '-D' confirms the DC immune characteristic required for your application. Ensure the vertical PCB footprint matches your layout constraints. Confirm RoHS compliance status if environmental regulations apply to your manufacturing process. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity.

Selection Notes

Select this model when DC bias currents are present in the measurement line, as standard transformers may saturate. The 50A rating suits moderate power applications requiring isolation. Verify that the operating frequency remains within the 20Hz to 1kHz window. Consider the vertical profile height against available board clearance before finalizing the design.

Part Context

This component belongs to the CR8300 series of current sense transformers. The series offers various ratios and configurations tailored for different current levels. The '-D' designation specifically indicates the DC immune variant, distinguishing it from standard AC-only models within the same product family.

Replacement Considerations

Direct substitutes include other DC immune variants from the CR8300 series such as CR8349-2000-D or CR8350-2000, provided they match the 50A rating and vertical form factor. Verify pin compatibility and physical dimensions before substitution.
