- Hybrid application transformer
- 600 ohm CT primary to 300/1200 ohm secondary
- 1000 mW output, 4 mA maximum primary D.C. current
- D.C. resistance 53 ohms primary / 63 ohms secondary (+/- 15%)
- Clinching lugs; 0.025" square pins on standard 0.2" grid
- 200 Hz - 15 kHz (+/- 1 dB), 250V rms insulation test
The 149V is the hybrid type in the 149 Series, with a 600 ohm center-tapped primary and a 300/1200 ohm secondary. It is intended for designers building hybrid audio circuits on a printed circuit board who need a compact open frame transformer with clinching lug mounting.
The 149 Series uses an economical, open type, horizontal bracket construction with pin-type terminals for P.C. board mounting, and adds clinching lugs for extra mounting strength. Windings are bifilar wound for balanced capacitive and resistance characteristics on pin bobbins spaced for a standard 0.2" grid, and the series is insulation tested at 250V rms.
The 149V is rated for 1000 mW with a maximum primary D.C. current of 4 mA. D.C. resistance is 53 ohms on the primary and 63 ohms on the secondary (+/- 15%). Frequency response is 200 Hz to 15 kHz (+/- 1 dB, ref. @ 1 kHz) and insertion loss is less than 1/2 dB. Connections follow schematic figure 7, which is unique to this part in the series.
Net weight is 1.0 oz. and shipping weight is 0.05 lbs (0.02 kg). The 149V is RoHS and REACH compliant, UPC 623980200200.
