140B

Overview

The Hammond Manufacturing 140B is an audio transformer belonging to the 140 series. It features a primary impedance of 30 Ohms and a secondary impedance of 60,000 Ohms (60k). The component is designed for signal transformation applications within electronic circuits. This specific part number is currently classified as obsolete by the manufacturer.

Part Context

This component belongs to the Hammond Manufacturing 140 series, which specializes in audio transformers and signal transformers. These units are engineered for precise impedance matching and signal transfer in audio frequency ranges. The series typically supports various winding configurations to meet specific circuit requirements.

Replacement Considerations

As the 140B is marked as obsolete, direct replacement availability may be limited. Engineers should consult Hammond Manufacturing for current equivalent models or verify compatibility with alternative audio transformers offering similar 30-ohm primary and 60k-ohm secondary impedance characteristics.
