Features
  • Exceptionally low profile for a 7mm coil - only 6.9mm max.
  • Type 7PS for AM circuit applications and 7PS High for FM circuit applications are ideal in IFT coils and in short wave oscillator circuits, due to their high Q (typically 90) and a wide inductance range.
  • The Q value is exceptionally steady throughout the tuning range (alignment) to simplify matching between circuits.
  • 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.
  • The coil form is wax-impregnated to form a moisture barrier against corrosion and to prevent microphonics (howling)..
  • Stand-offs on all four corners keep the coil straight during wave soldering.
  • Plated brass cover, to provide static and magnetic shielding.
  • Cup core provides additional magnetic shielding, assuring low EMI.
  • Presoldered terminal pins ensure a highly reliable PCB connection.
