CR8350-2000-F

Overview

The CR8350-2000-F is a current sense transformer from the CR Magnetics Inc. CR8300 series, designed for through-hole mounting. It features a non-invasive solid core construction with PC pin termination. The component supports a rated current of 100 A and operates within a frequency range of 20Hz to 200kHz. It exhibits a DC resistance of 73 Ohms and an turns ratio of 2000:1. The physical dimensions are specified as 1.024 inches in length, 0.670 inches in width, and a maximum installation height of 1.102 inches.

Feature Summary

• Non-invasive solid core design for direct conductor insertion without circuit interruption
• Through-hole mounting configuration utilizing PC pins for secure PCB integration
• Wide frequency response capability extending up to 200kHz for high-speed signal detection

Applications

• High-frequency current monitoring in power electronics circuits
• Isolated current sensing in motor drive systems
• Protection circuitry requiring fast transient current detection

Procurement Notes

Verify that the specific part number suffix matches the required winding ratio and impedance characteristics for your application. Confirm that the through-hole footprint aligns with the target printed circuit board layout. Ensure the operating frequency range covers the fundamental and harmonic content of the measured current to maintain accuracy. Check RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a high-current rating of 100 A is required alongside a wide bandwidth up to 200kHz. The solid core design necessitates access to the conductor path for installation. Consider the 73 Ohm DC resistance impact on secondary circuit loading. Compare against split-core alternatives if retrofitting existing wired connections is necessary without disconnecting the primary conductor.

Part Context

This device belongs to the CR8300 series of current sense transformers manufactured by CR Magnetics Inc. The series provides various current ratings and turns ratios tailored for different isolation and sensing requirements. The CR8350-2000-F specifically addresses applications demanding higher current capacity compared to lower-rated variants in the same product family.

Replacement Considerations

Direct substitutes include other CR8300 series models with matching 100A ratings and similar frequency responses, such as CR8350-1000-N or CR8350-2500-N, provided the turns ratio and impedance differences are acceptable for the specific circuit design.
