Overview
The Triad Magnetics F-133P is a laminated core power transformer designed for through-hole PCB mounting. It features a single primary winding rated for 115V input and dual secondary windings, each providing 15V. The unit has a total power rating of 1.5VA. Electrical configurations allow the secondaries to be connected in series or parallel to achieve different voltage and current outputs. The device operates at 50Hz or 60Hz frequencies and includes an isolation rating of 1500Vrms. It utilizes PC pin termination for secure board integration.
Feature Summary
- Dual secondary windings enable flexible series or parallel circuit configurations
- Laminated core construction supports standard AC frequency operation
- Through-hole PC pin mounting ensures stable mechanical attachment
Applications
- PC board power supply designs
- Solid-state power supply circuits
- Equipment requiring isolated low-voltage DC conversion
Procurement Notes
Verify that the specific revision matches the required electrical parameters. Confirm the physical dimensions align with the target PCB layout. Ensure the operating temperature range meets the environmental requirements of the final assembly. Check compliance documentation for regional regulatory standards.
Selection Notes
Choose this component when a 1.5VA capacity is sufficient for the load. Select based on the need for dual independent or combined secondary outputs. Consider the through-hole form factor if surface mount alternatives are unsuitable. Validate the 115V primary requirement against the available line voltage.
Part Context
This part belongs to the F series of power transformers from Triad Magnetics. The series offers various plug-in types tailored for solid-state applications. The F-133P specifically addresses needs for compact, reliable isolation in general-purpose electronic equipment.
Replacement Considerations
Consult official manufacturer substitution lists for verified equivalents. Generic replacements may differ in insulation class or physical footprint. Verify that any substitute maintains the same 1500Vrms isolation rating and 1.5VA power handling capability.
