Product Description
Product Overview
The Signal 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 a low profile is essential. They offer dual primaries (115/230 V, 50/60 Hz) and can be configured for series or parallel secondaries. Available in a power range of 2 VA to 48 VA, with heights from 0.65 to 1.375. The insulation system is Class B, 130 C, compliant with UL 1446.
