Overview
The Tamura TCS-01 is a surface-mount current sense transformer designed for high-frequency applications. It features a 1:20 turns ratio and supports a primary current rating of 6A. The component operates with a minimum frequency of 250kHz. Electrical characteristics include a primary DC resistance of 6mOhm, a secondary DC resistance of 550mOhm, and a primary inductance of 80µH. It utilizes a six-terminal configuration for reliable circuit integration.
Feature Summary
- Surface mount construction for automated assembly
- High-frequency operation capability starting at 250kHz
- Six-terminal design for secure PCB connection
Applications
- Current sensing in switching power supplies
- Isolated feedback circuits in converters
- Overcurrent protection systems
Procurement Notes
Verify the specific datasheet version to confirm terminal pinout and mechanical dimensions prior to integration. Ensure that the operating frequency remains above the 250kHz minimum threshold to maintain accurate signal transformation. Confirm RoHS compliance status if environmental regulations apply to the final product assembly.
Selection Notes
Select this component when a compact surface-mount solution is required for isolated current monitoring. The 1:20 ratio provides a stepped-down secondary signal suitable for standard control IC inputs. Consider the 6A primary limit and thermal performance under continuous load conditions during the design phase.
Part Context
This part belongs to Tamura's line of audio and signal transformers, specifically categorized as current sense devices. These components are engineered to provide galvanic isolation while transferring current information across circuit boundaries. They serve as critical elements in feedback loops where electrical separation between primary and secondary sides is mandatory.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility by matching the 1:20 ratio, 6A rating, and 80µH inductance specifications against alternative suppliers' data sheets before substitution.
