OEP A262A2E Audio Transformer 1+1:2+2 PCB Mount

The OEP A262A2E is a high-performance audio transformer engineered for direct PCB mounting on a 0.1 inch grid. It features dual windings on both the primary and secondary, offering a versatile range of impedance matching ratios suitable for input, interstage, and output stages. A foil screen between windings minimises interference, ensuring clean signal transfer.

With a turn ratio of 1+1:2+2, this transformer supports a primary impedance of 150 ohms and a secondary impedance of 600 ohms. It handles 100mW at 300Hz and operates across a frequency range of 30Hz to 35kHz, making it ideal for demanding audio applications. The encapsulated design with through-hole PC pins ensures reliable mounting and longevity.
