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).
