PE-51686NL Current Transformer - 20A Sensing | 50:1 Turns Ratio | 20kHz-200kHz Range
The PE-51686NL is a high-accuracy current transformer designed for switching power supplies, industrial automation, and energy monitoring systems. With a 20A rated current and 50:1 turns ratio, it delivers precise current measurement across a 20kHz-200kHz frequency range. The 5mH inductance and low 700mΩ secondary DCR ensure minimal power loss, while its compact through-hole design (17.01×9.90×20.32mm) simplifies integration into PCB-based power electronics.
5mH Inductance with ±1% Accuracy for Reliable Current Monitoring
Key Advantages:
✔ Wide Frequency Response: Ideal for SMPS, inverters, and motor drives
✔ Low-Impedance Secondary: 700mΩ reduces measurement errors
✔ Robust Construction: PC pin termination withstands high-vibration environments
✔ Industry-Standard Dimensions: Compatible with DIP/SMD layouts
