Features
  • Unique design features a cup core adjuster threaded directly into the shield, allowing the use of larger cores which greatly improves saturation levels and large signal handling capability.
  • This patented design is smaller than plastic support styles with similar characteristics.
  • Ideal for use as an AM IFT coil and in oscillator circuits, which produces a high Q (typically 70-140) and a wide inductance range.
  • The Q value is exceptionally steady throughout the tuning range (alignment) to make impedance matching between circuits faster and easier.
  • The coil form is wax-impregnated to form a moisture barrier against corrosion and to prevent microphonics (howling).
  • Plated brass cover provides static and magnetic shielding.
  • Cup core provides additional magnetic shielding, assuring low EMI.
  • Presoldered terminal pins ensure a highly reliable PCB connection.
