SP-50-B

Overview

The Triad Magnetics SP-50-B is a through-hole audio transformer designed for high-reliability applications. It features a power rating of 50 mW and operates within a temperature range of -40°C to 85°C. The unit provides 1000 VRMS isolation voltage at one second. Physical dimensions are 0.410 inches in length, 0.310 inches in width, with a maximum seated height of 0.465 inches. The component utilizes an epoxy molded case and gold-plated leads.

Feature Summary

• Epoxy molded case construction
• Gold-plated leads
• Through-hole mounting style

Applications

• Audio signal coupling
• Impedance matching circuits
• Line level interfacing

Procurement Notes

Verify the specific datasheet version for the SP-50-B to confirm exact electrical tolerances and pin configurations. Ensure the ordering suffix matches the required packaging type, as variations may exist between bulk and tape-and-reel options. Cross-reference physical dimensions against PCB layout constraints prior to final procurement decisions.

Selection Notes

Select this component when a compact, high-isolation audio transformer is required for through-hole assembly. The 50 mW power rating suits low-power line-level applications. Verify that the operating temperature range meets environmental requirements. Consider lead plating specifications if solderability or corrosion resistance is critical for the intended application environment.

Part Context

This part belongs to the Red Spec series from Triad Magnetics, known for high reliability. It serves as a specialized audio transformer variant within the broader product portfolio. The designation indicates specific manufacturing standards and material selections distinct from standard commercial grade components.

Replacement Considerations

Consult manufacturer cross-reference guides for verified substitutes. Generic equivalents may not match the specific isolation voltage or frequency response characteristics. Verify pin compatibility and physical footprint before substituting.
