P.C. Board Mount (148-149 Series)

P.C. BOARD MOUNT

AUDIO TRANSFORMERS

Pin type (0.25" length & 0.025" square), P.C. board mount.

•

Economical, open type, horizontal bracket construction. 149 Series includes clinching lugs for extra mounting

•

strength.

Frequency response 200 Hz. - 15 Khz. (+/- 1 db, ref. @ 1 Khz.).

•

Total distortion approximately 2% for drivers and 1% for outputs at 200 Hz., decreasing at higher frequencies.

•

Insertion loss less than 1/2 db.

•

Bifilar wound for balanced capacitive and resistance characteristics, on pin bobbins for standard 0.2" grid pin spacing.

•

Insulation test 250V RMS.

•

For rugged epoxy cast type units refer to our 102, 104, 106, or 107, 108 & 109 series.

•

Net weight: 0.6 oz. (148 Series) & 1.0 oz. (149 Series).

•

NOTES:

*1) For output transformers the current figure is for maximum unbalanced current

*2) D.C. resistance shown is for the total primary or secondary windings (ie: if unit contains multiple primary or

secondary windings the figure shown is with the windings connected in series).
