    Special Price $28.98 Regular Price $36.00 As low as $25.98

    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.

    MIL-Spec P/N: MIL-PRF-27/103-016

    Some are made by TRW/UTC.

    Application: Generally used in the input, output, amplifier, or oscillator stages of audio and sonar devices.
