  • Richard Jahre produces inductors in various types with axial and radial leads in fixed and tunable values. The single layer or multilayer windings are wound on insulating material, iron powder or ferrite cores. The optimal combination of core material and winding creates inductors for high reliability of professional engineering.
  • The types 71 and 72 consist of open cores with axial leads. The electrical properties are the same. The varnished versions of type 71 are especially applicable in the case of small space. Mainly type 72 will be used under stringent environment conditions. Theefore it is protected by a special plastik material. The types 72 are conforming to the requirements of MIL-C-15305. The types 72.01 and 72.10 are conforming to MIL-C-39010 and are qualified for air and space applications.
  • The inductor series 73 are cross-wound and have therefore a very low self-capacitance. Their leads are axial.
  • The inductor series 74 are miniature coils on bobbins with radial leads for direct assembly on through-hole pc-boards.
  • The serie 75 are smd-inductors.
  • Series 77 are inductors with low resistance for high current up to 12 A - EMI applications.
