Description:
These transformers operate in the 200 Hz to 15,000 Hz range, making them
suitable for a broad application spectrum in the audio industry. These devices
are used in line matching, telephone coupling, pulse trigger, driver, interstage,
output, isolation and input applications.
Operating Temperature Range: 0º C to 105º C
Electrical Specifications at 25º C:
1. Primary Impedance: 10000Ω CT
+ 15% with 600Ω load
2. Secondary Impedance: 2000Ω CT
3. Output: 100mW
4. Primary DC Unbalance: 4 Ma
5. Frequency Response: +
2db from 200 to 15,000 Hz
6. Impedance Matching: 10% over full frequency range
7. Longitudinal Balance > 45db
8. Insertion Loss @ 1K Hz: < 1.5db
9. Return Loss: > 26db
10. Total Harmonic Distortion < 0.5% between 275Hz and3.5KHz
11. DCR:
Primary (1-3) 750
Ω Nominal
Secondary (4-6) 217Ω Nominal
12. Turns Ratio: 2.24 : 1
13. Dielectric Strength 1500V Pri to Sec to Core
Construction:
Bobbin has plug-in terminals which are spaced to provide fixed mounting centers.
Pins are a rugged .042” square, minimizing the incidence of bent pins from
handling.
