CSE184L

Overview

The CSE184L is a low-frequency current sense transformer manufactured by Triad Magnetics, designed for through-hole mounting. It features a primary-to-secondary turns ratio of 1:16.67 and supports an input current rating of 1A within a frequency range of 50Hz to 400Hz. The component exhibits a DC resistance of 0.125 ohms on the primary side and 0.023 ohms on the secondary side. It maintains an ET constant of 30000 V·µs and utilizes PC pin termination for secure board integration.

Feature Summary

• Provides invasive current sensing capability with a fixed 1:16.67 turns ratio
• Engineered for low-frequency operation between 50Hz and 400Hz
• Supports through-hole mounting via PC pin termination style

Applications

• Low-frequency AC current monitoring in industrial power supplies
• Invasive current sensing in motor drive circuits
• Power factor correction (PFC) circuit feedback loops

Procurement Notes

Verify the specific manufacturer part number against official Triad Magnetics documentation to confirm active status and lead times. Ensure that the required 1A current rating and 50-400Hz frequency range align with your system design requirements before procurement. Cross-reference datasheet specifications for mechanical dimensions and thermal performance to guarantee compatibility with your PCB layout constraints.

Selection Notes

Select the CSE184L when invasive current measurement is required at low frequencies up to 400Hz. The 1:16.67 turns ratio determines the secondary output signal magnitude relative to the primary current. Consider the 0.125 ohm primary DC resistance for impact on circuit efficiency. Ensure the application environment supports through-hole assembly processes and that the physical footprint matches the available board space.

Part Context

The CSE184L belongs to the CSE18xL series of current sense transformers from Triad Magnetics. This series is characterized by robust construction suitable for demanding industrial environments. These components are specifically engineered to provide accurate current feedback in applications where non-invasive sensors may not offer sufficient precision or isolation requirements.

Replacement Considerations

Consult official Triad Magnetics substitution guides for verified alternative part numbers. Direct replacements must maintain identical electrical characteristics, including the 1:16.67 turns ratio and 1A current rating. Verify mechanical compatibility, particularly the through-hole PC pin configuration and overall dimensions, to ensure seamless integration without PCB redesign.
