P8202NLT

Current Sense Transformers Overview

The P8202NLT is a surface-mount current sense transformer manufactured by Pulse Electronics. It features a 1:20 turns ratio and operates within a frequency range of 50 kHz to 1 MHz. The component has a primary DC resistance of 6 mOhms and a secondary DC resistance of 550 mOhms. It supports a peak primary current of 10 A and includes an 80 µH secondary inductance. The physical dimensions are 8.38 mm in length, 7.21 mm in width, and 5.5 mm in height. It utilizes gull-wing terminals for mounting.

Current Sense Transformers Feature Summary

• Provides galvanic isolation with a 1:20 current transformation ratio
• Operates effectively across a wide frequency spectrum from 50 kHz to 1 MHz
• Designed for surface-mount installation using gull-wing terminal configuration

Current Sense Transformers Applications

• High-frequency current sensing in power supply circuits
• Overcurrent protection mechanisms in electronic systems
• Feedback control loops requiring isolated current measurement

Current Sense Transformers Procurement Notes

Verify the specific package variant and terminal style against design requirements before ordering. Confirm that the operating frequency range aligns with the target application's switching speed. Ensure the peak current rating of 10 A exceeds maximum expected transient loads to prevent saturation or damage during normal operation cycles.

Current Sense Transformers Selection Notes

Select this component when isolated current monitoring is required at frequencies above 50 kHz. The 1:20 ratio suits applications needing significant signal attenuation for safe measurement. Consider the 550 mOhm secondary resistance impact on downstream circuit loading. Verify compatibility with standard reflow soldering profiles for surface-mount assembly processes.
