Current Sense Transformers Overview

The PA1005.060QNL is a surface-mount current sense transformer manufactured by Pulse Electronics. It features a turns ratio of 1:60 and operates within a frequency range of 50kHz to 1MHz. The device supports a maximum current rating of 20 A. Electrical characteristics include a primary DC resistance of 0.75 mOhms, a secondary DC resistance of 2.25 Ohms, and a primary inductance of 720 µH. The component is designed for board mounting applications requiring precise current monitoring.

Current Sense Transformers Feature Summary

• Provides galvanic isolation between the primary circuit and the sensing electronics
• Enables accurate current measurement through a fixed 1:60 transformation ratio
• Operates effectively across a broad frequency spectrum from 50kHz to 1MHz

Current Sense Transformers Applications

• Power supply current monitoring
• Motor drive protection circuits
• Inverter control systems

Current Sense Transformers Procurement Notes

Verify the specific package dimensions and pin configuration against the official datasheet before integration. Confirm that the 20 A current rating aligns with the peak load requirements of the target application. Ensure the operating frequency range covers the switching frequencies present in the system to maintain signal integrity and accuracy.

Current Sense Transformers Selection Notes

Select this component when high-frequency current sensing is required without direct electrical contact. The low primary resistance minimizes power loss in the main current path. The 1:60 ratio offers a balance between sensitivity and dynamic range for medium-current applications up to 20 A.

Current Sense Transformers Part Context

This part belongs to Pulse Electronics' lineup of surface-mount current transformers. These components are engineered for compact designs where space constraints limit the use of larger through-hole alternatives. The series is commonly utilized in modern electronic equipment requiring efficient power management and protection mechanisms.
