SP-13

Overview

The Triad Magnetics SP-13 is a miniature audio transformer designed for impedance matching in signal processing circuits. It features a 5:1 turns ratio with a primary impedance of 1kCT and secondary impedance of 20kCT or 25kCT. The device operates within a frequency range of 300Hz to 100kHz, ensuring accurate signal transmission for audio applications. Constructed with through-hole PC pin terminals, it offers high reliability and durability. The unit provides 1000Vrms isolation between windings and utilizes encapsulated construction for environmental protection.

Feature Summary

• Provides precise 5:1 impedance transformation for audio signal integrity
• Encapsulated construction ensures mechanical stability and environmental resistance
• Through-hole mounting facilitates integration into printed circuit boards

Applications

• Audio signal impedance matching
• Solid state power supply design
• Control and instrumentation circuits

Procurement Notes

Verify the specific secondary impedance variant required (20kCT vs 25kCT) as specifications may vary by production batch. Confirm RoHS compliance status against current manufacturing dates. Ensure the selected component meets the thermal class requirements for the intended enclosure environment prior to final procurement.

Selection Notes

Select this component when a compact, high-reliability solution is needed for low-power audio signal coupling. The fixed 5:1 ratio suits specific impedance bridging needs. Consider the physical dimensions and terminal pitch for PCB layout compatibility. Evaluate the frequency response characteristics against the target audio bandwidth requirements to ensure minimal signal distortion.

Part Context

The SP-13 belongs to Triad Magnetics' Red Spec series, known for high reliability in demanding environments. This line of miniature impedance matching transformers is engineered for durability and precision. The series supports various audio and signal processing designs requiring robust magnetic components with consistent performance characteristics across operating conditions.

Replacement Considerations

Direct substitutes must match the 5:1 ratio, 1kCT primary impedance, and through-hole package. Verify that alternative components meet the 300Hz-100kHz frequency range and 1000Vrms isolation rating. Cross-reference physical dimensions to ensure PCB footprint compatibility without redesigning the host circuit board.
