115V / 230V Dual Primary AC Input Voltage Framework, Dual 12V / 24V (12-0-12V) Center-Tapped Secondary Output Configuration, 0.13A (130mA) Continuous Current Capacity (at 12V Output Mode / 0.065A at 24V Series Configuration), 3.12VA Volumetric Rating Printed Circuit Board (PCB) Mounting Configuration, Low-Loss Audio and High-Frequency Signal Interleaved Core Matrix, High-Conductivity High-Purity Copper Wire Windings, Red-Spec Monolithic High-Reliability Shielded Structural Design Blueprint, Symmetrical Through-Hole Straight Pin Component Terminals, High Stability Telecommunications and Audio Isolation Signal Line Node | High-performance industrial and audio-grade miniature printed circuit board signal coupling and low-power isolation step-down transformer manufactured by Triad Magnetics under foundational part catalog index A-131X (universally inventoried and cross-referenced inside master technical parts sheets under the shorthand item identifier A131X). Precision-engineered to run inside space-constrained audio mixing desks, broadcast line amplifiers, and telecommunication network routing cards, this heavy-duty miniature component utilizes a highly stable, interleaved copper winding layout layered over a high-permeability grain-oriented steel core. Built as an active element within Triad's historic "Red-Spec" high-reliability component matrix, it delivers a completely flat, linear frequency response track across broad kilohertz operational bands. It completely rejects inter-winding capacitive cross-coupling and dynamic line variations, forcefully blocking upstream transient noise spikes or primary switching harmonics from bleeding down onto adjacent telemetry sensors or sensitive analog computational logic rails. Widely implemented inside commercial studio audio equipment frames, negative-feedback amplifier pipelines, laboratory calibration instruments, and remote field telemetry rigs. | Industry Exact Equivalents: Triad A-131X, Triad Red-Spec A131X, Triad Magnetics A-131X | Industry Functional Cross-References: Tamura Audio Transformers, Hammond 140 Series Miniature Audio, Pico Electronics Subminiature Transformers, Microtran Signal Coupling Inductors (Note: Red-Spec signal transformers utilize explicit pin mapping arrays and strict impedance matching parameters; cross-verify your target circuit board track drill matrix grids and primary-to-secondary turns ratios prior to automated line staging) | Military Specification National Stock Number (NSN): 5950-01-101-0131 (Base High-Reliability Miniature Shielded Audio Transformer Matrix)
