RL-3430

Current Sense Transformers Overview

The RL-3430 is a current sense transformer manufactured by Renco Electronics, Inc. It features a 1:200 turns ratio and operates within a frequency range of 1kHz to 100kHz. The component has a secondary resistance of 4.5 Ohms and an inductance of 80 mH. It is designed for through-hole mounting.

Current Sense Transformers Feature Summary

• Provides electrical isolation for current sensing applications
• Supports high-frequency operation up to 100kHz
• Utilizes a 1:200 turns ratio for signal transformation

Current Sense Transformers Applications

• Current monitoring in switching power supplies
• Overcurrent protection circuits
• Feedback loop sensing in DC-DC converters

Current Sense Transformers Procurement Notes

Verify the specific manufacturer datasheet for precise electrical tolerances and thermal characteristics before integration. Confirm that the through-hole package dimensions align with your PCB layout requirements. Ensure the operating frequency range of 1kHz to 100kHz matches your system's switching speed. Check for RoHS compliance status if required by your manufacturing standards.

Current Sense Transformers Selection Notes

Select this component when a high turns ratio is needed for sensitive current detection. The 80 mH inductance supports stable performance at lower frequencies within the specified range. Consider the 4.5 Ohm secondary resistance for burden voltage calculations. Ensure the through-hole form factor fits your assembly process constraints.

Current Sense Transformers Part Context

Renco Electronics, now part of Standex Electronics, specializes in custom magnetic components. The RL series includes various transformers and inductors. This model belongs to the current sense transformer category, distinct from general-purpose power transformers or chokes found in other product lines.

Current Sense Transformers Replacement Considerations

No direct public substitute part numbers are confirmed for the RL-3430. Any replacement must match the 1:200 ratio, 100kHz maximum frequency, and 80 mH inductance specifications. Verify physical footprint compatibility for through-hole installation.
