SP-5

Overview

The SP-5 is an audio transformer manufactured by Triad Magnetics, designed for through-hole mounting. It features a primary impedance of 50kCT and a secondary impedance of 1kCT, with a turns ratio of approximately 7.1:1. The component operates within a frequency range of 300 Hz to 100 kHz and supports a power level of 25 mW. It provides isolation voltage of 1 kV and functions within an operating temperature range of -40°C to 85°C. Physical dimensions are 0.410 inches in length, 0.310 inches in width, and a maximum seated height of 0.465 inches.

Feature Summary

• Encapsulated construction for durability
• Through-hole PCB mounting style
• Audio coupling capability

Applications

• Data voice coupling
• Audio signal interfacing

Procurement Notes

Verify the specific datasheet version and manufacturer specifications before integration. Confirm that the encapsulated package and through-hole pin configuration match the target PCB layout requirements. Ensure the operating temperature range and isolation voltage meet the system's environmental and safety standards. Cross-reference impedance values with circuit design parameters to ensure proper signal matching.

Selection Notes

Select this component when a 50kCT to 1kCT impedance transformation is required for audio applications. The encapsulated design offers protection against environmental factors compared to unshielded variants. Verify that the physical footprint fits the available board space and that the through-hole pins align with the manufacturing process capabilities.

Part Context

This part belongs to the audio transformer category from Triad Magnetics. It serves as a specialized component for impedance matching in audio circuits. The encapsulated variant distinguishes it from other models in the series that may offer different mounting styles or shielding options.
