PH9505.100NLT

Current Sense Transformers Overview

The PH9505.100NLT is a surface mount current sense transformer manufactured by Pulse Electronics. It features a primary-to-secondary turns ratio of 1:100 and supports a maximum primary current rating of 30 A. The device operates within a frequency range of 20 kHz to 1 MHz, with a maximum inductance of 7 mH. Electrical characteristics include a primary DC resistance of 0.5 milliohms and a secondary DC resistance of 3.1 ohms. The component is designed for board mounting and complies with RoHS standards.

Current Sense Transformers Feature Summary

• Provides galvanic isolation between high-current primary circuits and low-voltage sensing secondary circuits
• Optimized for high-frequency operation up to 1 MHz for accurate signal representation
• Designed for surface mount technology integration into compact PCB layouts

Current Sense Transformers Applications

• Current monitoring in power supply modules
• Overcurrent protection circuitry in industrial equipment
• Feedback loop sensing in switching mode power converters

Current Sense Transformers Procurement Notes

Verify the specific manufacturing revision against the latest datasheet before procurement, as component specifications may be subject to change without notice. Confirm that the surface mount footprint dimensions align precisely with the target PCB design to ensure proper solder joint integrity during assembly processes.

Current Sense Transformers Selection Notes

Select this component when a 1:100 transformation ratio is required for current sensing applications operating above 20 kHz. Ensure the primary conductor can handle up to 30 A continuously. Consider the thermal environment, as the maximum operating temperature reaches +150 C, which suits high-heat industrial environments better than standard commercial grade alternatives.
