PA1005.030NL

Current Sense Transformers Overview

The PA1005.030NL is a surface-mount current sensing transformer manufactured by Pulse Electronics, designed for high-frequency applications within the 20 kHz to 1 MHz range. It features a 1:30 turns ratio and supports a primary current rating of 20 A. The component exhibits a maximum primary DC resistance of 0.75 mOhms and a secondary DC resistance of 870 mOhms. With an inductance of 180 µH and a gull-wing SMD package, it provides reliable isolation voltage of 1000 Vrms for precise current monitoring in power systems.

Current Sense Transformers Feature Summary

• Provides galvanic isolation with a 1:30 turns ratio for accurate current measurement
• Engineered for high-frequency operation ranging from 20 kHz to 1 MHz
• Features low primary DC resistance to minimize insertion loss in high-current paths

Current Sense Transformers Applications

• High-current power supply monitoring circuits
• Inverter and motor drive current sensing
• Battery management system (BMS) protection

Current Sense Transformers Procurement Notes

Verify that the specific part number matches the required 1:30 ratio and 20 A rating for your design. Confirm the gull-wing package dimensions align with your PCB footprint. Ensure the 1000 Vrms isolation voltage meets your safety requirements. Check for RoHS compliance status if applicable to your manufacturing standards.

Current Sense Transformers Selection Notes

Select this component when a 1:30 transformation ratio is necessary for signal conditioning. Consider the 20 A primary current limit for load capacity. Evaluate the 180 µH inductance against your frequency response needs. The low primary resistance is suitable for minimizing voltage drop in high-power applications.

Current Sense Transformers Part Context

This device belongs to the PA1005 series of current sensing transformers from Pulse Electronics. It is distinct from the PA4345 power inductor series due to its transformer topology and sensing function. The PA1005 series is optimized for invasive current monitoring in compact surface-mount designs.

Current Sense Transformers Replacement Considerations

Cross-reference with PA1005.100NL for different ratios or PA1005.100QNL for automotive qualification. Verify electrical parameters match before substitution.
