Product Description
Product Overview
Signal's LP Series Flathead Low Profile Transformers are designed for low power and critical height applications. Utilizing 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 (115/230 V, 50/60 Hz) and can be configured for series or parallel secondaries.
