CR8348-1000

Overview

The CR8348-1000 is a current sense transformer from the CR8300 series by CR Magnetics Inc. It features a non-invasive solid core design with a primary current rating of 20 A and a turns ratio of 1000:1. The device operates within a frequency range of 20 Hz to 1 kHz and has a DC resistance (DCR) of 24 Ohms. It utilizes through-hole mounting with PC pin termination. Physical dimensions are 26.00 mm in length, 17.00 mm in width, and a maximum installation height of 28.00 mm.

Feature Summary

• Non-invasive solid core construction for isolated current sensing
• Through-hole mounting with PC pin termination
• Frequency response optimized for 20 Hz to 1 kHz operation

Applications

• Power supply monitoring
• Motor drive systems
• Industrial automation control

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to ensure correct packaging and variant selection. Confirm that the component meets required RoHS compliance standards for the target market. Cross-reference the distributor part number with the official CR Magnetics catalog to validate authenticity and avoid counterfeit components during acquisition.

Selection Notes

Select this model when a 20 A primary current rating and 1000:1 ratio are required for non-invasive AC current measurement. Ensure the application frequency falls within the 20 Hz to 1 kHz operational band. Verify that the through-hole package and physical dimensions fit the PCB layout constraints. Compare DCR specifications against burden resistor requirements for accurate signal conditioning.

Part Context

This component belongs to the CR8300 series of rugged wire lead current transformers. These sensors provide isolated measurement by installing around a current-carrying wire. The output voltage across a resistive burden is proportional to the input AC current, supporting remote electrical load monitoring and phase loss detection in industrial environments.

Replacement Considerations

The CR8349-1000-N serves as a related alternative within the same product family, offering similar functionality but with a higher 50 A primary current rating. Verify compatibility regarding physical footprint and electrical parameters before substitution.
