Product Description
Signal LP Series Flathead Low Profile Transformers
Product Overview
The Signal LP Series transformers are designed for low power and critical height applications. Featuring hum-bucking (semi-toroidal) construction, these transformers minimize radiated magnetic fields, making them ideal for PC board applications where space is limited. They offer dual primaries for versatile voltage input and can be configured for series or parallel secondary connections.
