Audio Transformers are transformers that are used over the audio frequency range. Audio Transformers are used in a variety of applications. They can provide galvanic isolation, signal gain/loss, match impedances between two interfaces, can be used as a reference and to provide feedback signal. Pico Electronics’ Audio Transformers are manufactured to MIL-PRF-27 Grade 5 Class S. These ultra-miniature transformers are made for durability while maintaining their electrical characteristics. All catalog transformers are manufactured to meet Mil-Std-202, method 107, thermal shock from -55°C to +130°C. All units can be manufactured with a 300 thermal cycle guarantee. Standard as well as custom designs are available. Pico Electronics, Inc. is an approved QPL source.

- PICO - C3187 - Transformer, Audio. Ultra-Miniature 600CT / 600CT.
PICO - C3187 Transformer, Audio.
Audio transformers are low-power signal devices optimized for transmission of wide-frequency AC signals with very low distortion. The transformer has no direct connection between the primary and secondary windings, the electrical energy transferred using electromagnetic induction. Due to this isolated property between primary and secondary, the transformer provides electrical isolations between primary and secondary, which means from the input and output or vice versa.
Ultra-Miniature 600CT / 600CT to 20kHz 500mw.
Fequency Rating: 400.0 hertz minimum single component and 100.0 kilohertz maximum single component
Mounting Bolt Circle: 0.200" Nominal Single Mounting Facility Single Center Group
Inclosure Type: Fully inclosed
Winding Operating Current: 4.0 milliamperes dc nominal single component single primary
Six 25mm Wire Leads.
Dual 150-ohm windings (combined) on each side.
Dimensions: Length 0.360 X Diameter 0.350 (10mm X 8.6mm)
Federal P/N's: 01-268-8395, Military NSN 5950-01-268-8395.
