SP-66

Overview

The Triad Magnetics SP-66 is a high-reliability audio transformer designed for PCB through-hole mounting. It features a 1:1 turns ratio with primary and secondary impedances of 10 kOhm, each including a center tap. The device supports a rated DC voltage of 150V and operates at frequencies up to 100kHz. Electrical characteristics include a current rating of 1mA, a power rating of 50mW, and a primary resistance of 1 kOhm. Isolation capability is rated at 1000VRMS for one second. The unit utilizes PC pin termination style and is housed in a UL94 V-0 rated molded case.

Feature Summary

High reliability construction ensuring durability and precision for demanding designs
UL94 V-0 rated molded case with recessed design facilitating solder inspection
Precision-spaced plug-in terminals providing fixed mounting centers

Applications

Audio signal processing circuits requiring impedance matching
High-reliability electronic systems demanding durable components
PCB-based audio interface designs

Procurement Notes

Verify the specific datasheet revision when sourcing, as documentation may vary slightly between distributors. Confirm that the required center-tap configuration matches the application schematic. Ensure the through-hole footprint aligns with the board layout, noting the precision spacing of the terminals. Cross-reference the isolation voltage requirements against the 1000VRMS specification to guarantee safety compliance in the final assembly.

Selection Notes

Select this component when a 10 kOhm center-tapped audio transformer is required for through-hole implementation. The 50mW power rating suits low-power signal applications rather than high-power transmission. Consider the physical dimensions and terminal spacing if space constraints exist on the PCB. The high isolation voltage makes it suitable for applications requiring significant potential difference between windings.

Part Context

The SP-66 belongs to Triad Magnetics' series of high-reliability audio transformers. This line emphasizes durability and precision for modern electronic designs. The product family typically includes various impedance ratios and power ratings, all sharing robust construction standards. These transformers are engineered to meet strict performance criteria for professional audio and industrial electronics.
