56050C

Overview

The Murata Power Solutions 56050C is a through-hole current sensing transformer designed for primary currents up to 10 A. It features a 50:1 turns ratio, delivering a secondary output of 1 A. The component operates within a frequency range of 20 kHz to 200 kHz and supports an isolation voltage of 500 V. Electrical characteristics include a primary DC resistance of 0.13 Ω, a secondary DC resistance of 0.2 Ω, and an inductance value of 4.5 mH. Physical dimensions are 16.79 mm in length, 20.19 mm in depth, and 8.89 mm in width. The unit functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Provides galvanic isolation between high-current primary circuits and low-voltage secondary sensing stages
• Delivers accurate current replication via a fixed 50:1 turns ratio for signal conditioning
• Supports wideband operation from 20 kHz to 200 kHz for switching power applications

Applications

• Current monitoring in switch-mode power supplies
• Overcurrent protection circuits in industrial equipment
• Feedback control loops in AC/DC converters

Procurement Notes

Verify the specific ordering suffix against official Murata documentation to confirm exact electrical tolerances and packaging configurations. Ensure that any selected variant matches the required thermal rating and insulation class for the target application environment. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm availability and lead times prior to finalizing procurement orders.

Selection Notes

Select this component when a robust, through-hole solution is required for isolating high-current signals in frequencies up to 200 kHz. The 10 A primary rating and 1 A secondary output make it suitable for direct integration into standard current-sense amplifier inputs. Consider the physical footprint and lead spacing constraints during PCB layout to ensure proper mechanical fit and solder joint integrity.
