CRZ8359-2K5W

Overview

The CRZ8359-2K5W is a current sense transformer from the CR Magnetics Inc. series, designed for through-hole mounting with PC pin termination. It features a non-invasive solid core construction and supports a frequency range of 50Hz to 60Hz. The component has a rated current of 50A, a turns ratio of 1:2000:5, and a DC resistance of 55 Ohms. Its physical dimensions are optimized for standard industrial PCB layouts.

Feature Summary

• Non-invasive solid core design for direct conductor insertion without circuit interruption
• High isolation capability suitable for safety-critical power monitoring applications
• Through-hole mounting configuration ensures mechanical stability in high-vibration environments

Applications

• Industrial motor drive current monitoring
• Power supply output current sensing
• Inverter and converter protection circuits

Procurement Notes

Verify the specific suffix '2K5W' against the manufacturer's latest datasheet to confirm impedance and ratio specifications. Ensure the ordering part number matches the required through-hole package and terminal style. Cross-reference the UL file number E131668 for compliance requirements relevant to your target market regulations.

Selection Notes

Select this component when a 50A primary current rating and 50Hz-60Hz operating frequency are required. The 55 Ohm secondary resistance must be compatible with the downstream signal conditioning circuitry. Consider the physical footprint and lead spacing to ensure compatibility with the intended printed circuit board layout.

Part Context

This model belongs to the CRZ83xx series of current sense transformers, which are engineered for precise AC current measurement in power electronics. The series utilizes robust magnetic materials to maintain linearity and low phase shift across the specified frequency band, supporting reliable feedback control in industrial power systems.

Replacement Considerations

Direct substitutes include CRZ8345-2K5W and CRZ8359 variants with matching ratios. Verify that alternative parts share the same 1:2000:5 ratio, 55 Ohm resistance, and through-hole package dimensions to ensure electrical and mechanical interchangeability.
