Availability: Product is built to order.
Ship date: 6 weeks
$27.39

Design
Mathematical and design analysis of the highly successful 1953 RCA ribbon microphone transformer together with new materials offer a new standard.

Magnet Wire
All units are wound with the finest virgin copper magnet wire. All windings use heavy insulated wire to provide excellent manufacturing yield, lower customer cost and superior life.

The Core
EDCOR uses the finest Super "Q" 80% Nickel cores. Each unit is hand stacked to assure at least 92% stack.

The Bobbin
EDCOR's royal blue bobbin with black finishing tape.

Sheilding
This unit has an outer copper shielding around winding and core to help eliminate outside interference.

Termination/Mounting
This unit is designed for printed circuit board mounting. For footprint and suggested hole and pad size please see the dimensional drawing.
