P.C. Board Mount (148-149 Series)  
148 Series  
P.C. BOARD MOUNT  
AUDIO TRANSFORMERS  
149 Series  
• 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).
