CR8348-2000-F

Overview

The CR8348-2000-F is a current sense transformer from the CR8300 series by CR Magnetics Inc., designed for through-hole mounting. It features a 50 A current rating and a 2000:1 current ratio, suitable for applications requiring precise AC current monitoring. The device operates within a frequency range of 20 Hz to 200 kHz, ensuring effective performance in high-frequency switching environments. Key electrical specifications include a DC resistance (DCR) of 88 Ohms. The component utilizes PC pin termination for secure board connection and has a compact form factor measuring 0.925 inches in length and 0.433 inches in width.

Feature Summary

• Non-invasive solid core design for direct conductor insertion without circuit interruption
• High-frequency operational capability extending up to 200 kHz for modern power electronics
• Through-hole mounting configuration with PC pin termination for robust mechanical stability

Applications

• Switch-mode power supply (SMPS) output current monitoring
• Motor drive systems for phase current sensing
• Inverter and converter circuits for real-time feedback control

Procurement Notes

Verify that the specific ordering suffix matches the required current ratio and impedance characteristics. Confirm that the through-hole footprint dimensions align with the PCB layout constraints. Ensure the operating frequency range covers the maximum switching frequency of the target application to maintain accuracy. Check RoHS compliance status if environmental regulations apply to the final product assembly.

Selection Notes

Select this model when a 50 A primary current rating and a 2000:1 transformation ratio are required. The 88 Ohm secondary impedance must be compatible with the burden resistor or amplifier input stage. Consider the 200 kHz upper frequency limit for high-speed switching applications. Ensure the physical size fits within the available space on the printed circuit board while maintaining adequate clearance for thermal management.

Part Context

This component belongs to the CR8300 series of PCB-mounted current transformers. The series offers various current ratings and ratios to suit different power levels. The CR8348-2000-F specifically targets medium-power applications requiring high isolation and accurate current replication. Its design supports integration into compact power modules where space efficiency and reliable signal transmission are critical for system performance.

Replacement Considerations

The CR8349-2000 is listed as an alternative part number within the same manufacturer's catalog. Verify compatibility regarding frequency response and physical dimensions before substitution. Ensure the replacement maintains the same 2000:1 ratio and 50 A rating to preserve circuit functionality.
