1 1/4 x 1 1/2 in. Glass Filled Nylon 6/6 Coil Bobbin.
Get shipping cost estimate in cart.
Bobbin
Injection molded Nylon 6/6 with the addition of 30%-35% glass fibers. The addition of glass fibers allows a higher heat deflection temperature and it brings the material to a class HB UL temperature classification..
Core
These bobbins are design for use with an E-I core material.
Termination
Transformer bobbins without terminals require soldering of lead wires directly to the magnet wire using a secondary means of strain relief..
Mounting
Transformer with these types of bobbins may require mounting hardware, such as channel/frame, brackets, or end cover.
