Product Overview
The 149U is a 4mA Audio Transformer, 600Ω primary, 800Ω secondary impedance with economical, open type, horizontal bracket construction, 0.25-inch length and 0.025-inch square pin type, PC board through hole mounting. This transformer features clinching lugs for extra mounting strength, bifilar wound for balanced capacitive and resistance characteristics on pin bobbins for standard 0.2-inch grid pin spacing, total distortion approximately 2% for drivers and 1% for outputs at 200Hz, decreasing at higher frequencies, insertion loss less than 1/2dB, insulation test 250V RMS. Suitable for output application.
- 2 x 53Ω ±15% Primary DC resistance
