It supports a voltage rating of 1000Vrms and functions within an operating temperature range of -40°C to 85°C.
Feature Summary
- Center-tapped primary winding configuration for balanced audio signal processing
- Through-hole mounting design for secure PCB integration
- Wide frequency response suitable for high-fidelity audio applications
Applications
- Audio signal isolation in professional sound systems
- Impedance matching between audio stages
- Balanced-to-unbalanced audio conversion circuits
Procurement Notes
Verify the specific suffix 'B' against official Triad Magnetics documentation to confirm exact impedance and tolerance variations. Ensure the component meets required thermal and voltage ratings for the target application environment. Cross-reference datasheet parameters with supplier specifications to avoid discrepancies in pinout or mounting dimensions.
Selection Notes
Select this component when a 1.5k ohm center-tapped primary is required to match a 600 ohm secondary load. Consider the 100kHz upper frequency limit for high-frequency audio fidelity. Evaluate the through-hole package constraints against available PCB space and ensure the 50mW power rating suffices for the signal level.
Part Context
The SP-52-B belongs to Triad Magnetics' audio transformer series, which provides various impedance ratios for audio equipment. This specific model addresses applications requiring precise impedance transformation between high-impedance sources and standard 600 ohm lines, commonly found in broadcast and studio gear.
