56300C

Overview

The Murata Power Solutions 56300C is a through-hole current sense transformer designed for high-accuracy AC current sensing applications. It features a primary winding with 300 turns and supports a maximum primary current of 10 A. The secondary output provides a 1 A current signal. Key electrical parameters include an inductance range of 180 mH to 335 mH, a minimum operating frequency of 20 kHz, and a maximum operating frequency of 200 kHz. The device operates within a temperature range of -40°C to 85°C.

Feature Summary

• Provides accurate AC current sensing via a 300-turn primary winding configuration
• Delivers a standardized 1 A secondary current output for downstream processing
• Operates effectively within a wide frequency band from 20 kHz to 200 kHz
• Engineered for reliable performance across an extended industrial temperature range

Applications

• AC current monitoring in power supply systems
• Current sensing in switch-mode power supplies
• Isolated current measurement in industrial control circuits

Procurement Notes

Verify the specific datasheet version and manufacturing lot details upon order confirmation. Ensure that the PCB layout accommodates the through-hole mounting requirements and maintains adequate clearance for the component's physical dimensions. Confirm that the operating frequency range aligns with the system's switching or line frequency to guarantee accurate transformation ratios and minimal phase shift errors during operation.

Selection Notes

Select this component when a robust, through-hole solution is required for isolating and measuring AC currents up to 10 A. The 300-turn ratio offers a balance between sensitivity and burden voltage considerations. Consider the 1 A secondary output capability when designing the burden resistor network to ensure appropriate voltage levels for subsequent analog-to-digital conversion or comparator stages without exceeding component ratings.
