Inductors

LBA Technology "Blue Line" RF inductors are based on over 30 years of proven international performance. Blue Line inductors are unsurpassed for hi-Q, stability, and low RF losses. These inductors are manufactured from heavy silver plated copper conductors and brass fittings, treated to resist tarnishing. Windings are insulated with melamine or G-1 0 epoxy laminates. These materials are recognized for their exceptional RF qualities, arc resistance, mechanical strength, and low moisture absorption. Supporting frames are engineered to permit maximum access to windings for convenience in adjustment. The metallic frames are separated by insulators to prevent induced current flow.

Variable inductors are fabricated with heavy-duty plated brass rotors. Contact with the inductor winding is via a spring-loaded roller, and current take-off from the rotor is through spring wiper contacts. This design minimizes contact losses, and maximizes stability of adjustments.

A full line of clips are available for tapping Blue Line inductors. Clips for current ratings from 7 to 20 amps are fabricated of tin plated spring metal and are designed for "push on" installation. Clips for 30 amp and larger inductors are machined in silver plated brass, and are in the form of screw adjusted split clamps for maximum contact area.

Blue Line inductors are made in standard sizes with current ratings from 7 amps to 150 amps. Standard inductances range from 5 uH to 150 uH. Other values may be furnished on a custom basis. The tables below depict standard values and characteristics.

Note: Inductance values are typical at 540 kHz and will vary with frequency due to distributed capacity. Consult factory for close tolerance inductors.
