CST-1010

Overview

The CST-1010 is a current sense transformer manufactured by Triad Magnetics, designed for non-invasive solid core applications. It operates within a frequency range of 50 Hz to 60 Hz and supports a primary current rating of 10 A. The device features a turns ratio of 1000:1 and a secondary DC resistance (DCR) of 40 Ohms. With a power rating of 10 mW and an 8.5 mm core size, it utilizes through-hole radial mounting for PCB integration.

Feature Summary

• Non-invasive solid core design for direct wire sensing
• High isolation via 1000:1 current transformation ratio
• Through-hole radial package for standard PCB mounting

Applications

• AC line current monitoring in power supplies
• Overcurrent protection circuits operating at 50/60 Hz
• Power quality analysis equipment

Procurement Notes

Verify the specific datasheet version from Triad Magnetics or authorized distributors to confirm mechanical dimensions and electrical tolerances. Ensure the application environment matches the 50/60 Hz operational frequency and 10 A current limits. Cross-reference the 40 Ohm DCR specification with downstream circuit requirements before finalizing procurement.

Selection Notes

Select this component when non-invasive AC current measurement is required at standard utility frequencies. The 1000:1 ratio suits applications needing significant signal attenuation for safe interfacing with low-voltage sensing electronics. Verify that the 10 A primary rating exceeds the maximum expected load current to prevent saturation.

Part Context

This part belongs to Triad Magnetics' current sense transformer portfolio, which provides isolated sensing solutions for power management systems. These components are engineered for reliability in industrial and commercial power conversion environments where galvanic isolation between high-current lines and sensitive control circuitry is mandatory.
