SP-52

Overview

The SP-52 is an audio and signal transformer manufactured by Triad Magnetics, designed for high-reliability applications. It features a primary impedance of 1.5 kΩ and a secondary impedance of 600 Ω, resulting in a turns ratio of 1.58:1. The device supports a frequency range from 300 Hz to 100 kHz and has a power rating of 50 mW with a current rating of 3 mA. Primary DC resistance is 168 Ohms. It offers 1 kV isolation voltage and operates within a temperature range of -40°C to +85°C. The component utilizes PC pin termination for through-hole mounting.

Feature Summary

• Provides galvanic isolation between circuits with a 1 kV dielectric strength
• Supports wideband audio and signal coupling across specified frequency ranges
• Engineered for high reliability in demanding operational environments

Applications

• Audio signal coupling
• Telecommunications line interfacing
• Impedance matching in signal processing chains

Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with Triad Magnetics or authorized distributors before procurement. Confirm that the 1.5 kΩ primary impedance variant matches the design requirements, as impedance values are critical for proper circuit integration. Ensure thermal management aligns with the specified operating temperature limits during installation.

Selection Notes

Select the SP-52 when a 1.5 kΩ to 600 Ω transformation ratio is required for audio or signal applications. Consider this component for designs needing robust isolation and a wide frequency response up to 100 kHz. Evaluate the 50 mW power handling capability against the expected signal levels to ensure operation within safe limits without saturation.

Part Context

The SP-52 belongs to Triad Magnetics' Red Spec series, which targets high-reliability performance standards. This series is often utilized in industrial and telecommunications sectors where consistent electrical characteristics and durability are prioritized over cost. The component represents a specialized solution for precise impedance transformation in analog signal paths.

Replacement Considerations

Cross-reference part numbers such as MET-31 or TY-145P if alternative impedances or form factors are acceptable. Verify that substitute components maintain the required 1.5 kΩ primary impedance and 1 kV isolation rating to ensure functional equivalence in the existing circuit design.
