Hammond Manufacturing Company Inc. Transformers - Audio Transformers - Signal Level 148R

Description
Features 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 and 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). 3) Pins are not labeled on the units, but a dot indicates the position of pin 1. The rest of the pins can be determined after reviewing the schematic below.
