Overview
The TE Connectivity Passive Product model 1-1672324-7 is a laminated core power transformer with a rated capacity of 1.1VA. It features a primary voltage configuration supporting 115V and 230V inputs connected in parallel. The secondary side provides dual output options: a parallel connection yielding 10V at a maximum current of 110mA, or a series connection providing 20V at 55mA. This component utilizes through-hole mounting technology for integration into electronic circuits.
Feature Summary
- Laminated core construction for efficient magnetic flux guidance
- Dual primary voltage support for flexible input compatibility
- Configurable secondary outputs allowing parallel or series connection modes
Applications
- General purpose AC to DC power supply units
- Electronic equipment requiring isolated low-voltage DC rails
- Industrial control systems with standard mains input
Procurement Notes
Verify the specific datasheet version corresponding to part number 1-1672324-7 to confirm electrical tolerances and thermal characteristics. Ensure that the procurement documentation explicitly lists the laminated core type and the 1.1VA rating. Cross-reference the pinout diagram against the target PCB layout to guarantee correct alignment of primary and secondary windings before finalizing orders.
Selection Notes
Select this transformer when a compact 1.1VA isolation barrier is required between mains voltage and low-voltage circuitry. The configurable secondary winding allows designers to choose between higher current at lower voltage or lower current at higher voltage based on load requirements. Verify that the physical dimensions accommodate the available board space for through-hole assembly.
Part Context
This component belongs to the TE Connectivity Passive Product portfolio, specifically within the power transformers category. It serves as an isolation device converting standard AC line voltages to safer, lower levels suitable for downstream rectification and regulation stages in consumer and industrial electronics.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Consult manufacturer catalogs for direct equivalents with matching VA ratings and winding configurations.
