UTC Audio Matching Transformer Interstage Transef. Primary: 2K / 2.5K Ohms CT, Secondary: 8K / 10K Ohms 100mw W05

Typical Application: isolation or interstage (Ratio 1:1:1) also wide pulse application PACKAGING Hermetically sealed. A UTC pioneered structure. The bobbin is completely rigid eliminating stress and wire movement. The turns are circular in shape rather than square, eliminating turn corner stress and effecting uniform wire lay. No tapes are employed in connecting coil wire and external leads. They are rigidly anchored in secure terminal board fashion providing strain relief. The leads used on the stock DI -T transformers are non-insulated solid .016 diameter Du met leads. Units are fully ruggedized, hermetically sealed , metal cased to Mil Grade 4, Class R, Life X. PERFORMANCE The UTC DI-T Family transistor transformers provide unprecedented power hand ling capacity and reliability, coupled with small size. Electrical parameters and areas of application exceed conventional transformer capabilities. Higher performance is obtained when used in push pull with balanced DC. FREQUENCY RESPONSE ± 3 db 300 Hz to 20 kHz. APPLICATION Units can be used for different impedances, keeping in mind that impedance ratio is constant. Lower source impedance will improve hum bucking response and level ratings .. . higher source will reduce them. Units may be used reversed, input to secondary. Units can be used at frequencies well above 20 kHz. Satisfactory applications for frequencies up to and above 100 kHz have been developed. PULSE APPLICATION In pulse coupling impedance matching applications, (when measured with a 30 microsecond input pulse voltage wave). typical values for these transformers are : 5% or less droop, zero overshoot and less than 10% backswing. RELIABILITY The exceptional reliability of DI-T family units, inherent in their unique structure, has been dynamically proven in the field .
