CR8320-1600

Overview

The CR8320-1600 is a non-invasive solid core current sense transformer manufactured by CR Magnetics Inc. Designed for through-hole PCB mounting, this component features a turns ratio of 1600:1 and supports a maximum current rating of 10 A. It operates within a frequency range of 20 Hz to 1 kHz and exhibits an impedance of 95 Ohms. The device utilizes a vertical PCB form factor with a window size of 0.22 inches and maintains a maximum RMS voltage of 1.8 V.

Feature Summary

• Non-invasive solid core design for direct conductor insertion
• Through-hole mounting configuration for PCB integration
• High turns ratio of 1600:1 for precise signal transformation

Applications

• General purpose vertical PCB current monitoring
• Solid core current sensing in industrial electronics
• AC current measurement circuits requiring galvanic isolation

Procurement Notes

Verify the specific ordering suffix and package variant against the manufacturer's latest datasheet before procurement. Confirm that the 10 A current rating and 1600:1 ratio align with the target circuit requirements. Ensure the through-hole footprint matches the PCB layout constraints. Cross-reference the 20 Hz to 1 kHz frequency response with the application signal characteristics to guarantee operational accuracy.

Selection Notes

Select this component when a non-invasive solid core solution is required for AC current monitoring on a printed circuit board. The 1600:1 turns ratio suits applications needing significant signal attenuation from primary to secondary windings. The through-hole construction provides mechanical stability for vertical mounting. Consider the 95 Ohm impedance and 10 A limit when designing the burden resistor network and thermal management strategy for the host system.

Part Context

This part belongs to the CR8320 series of PCB mounted current transformers from CR Magnetics Inc. The series utilizes high-quality silicone steel cores to ensure reliable performance. The CR8320-1600 specifically denotes the 1600:1 turns ratio variant within this family, distinguishing it from other ratios available in the same physical package and mounting style.

Replacement Considerations

Direct substitutes must match the 1600:1 ratio, 10 A rating, and through-hole vertical PCB mounting style. Verify compatibility with the 20 Hz to 1 kHz frequency range and 95 Ohm impedance. Ensure the 0.22-inch window size accommodates the primary conductor. Consult manufacturer cross-reference lists for confirmed equivalent part numbers.
