Air Core Inductor Air cored inductor is the type where no solid core exists inside the coils. In addition, the coils that wound on nonmagnetic materials such as ceramic and plastic, are also considered as air cored. This type does not use magnetic materials in its construction.
Carbon film resistor applications. Typical use for carbon film resistors is in high voltage and temperature applications. Operating temperatures are up to 15kV with a nominal temperature of 350°C. Examples are high voltage power supplies, radar, x-rays and laser. Manufacturing. Carbon film resistors are made with a deposition process.
Many inductors have a magnetic core made of iron or ferrite inside the coil, which serves to increase the magnetic field and thus the inductance. Along with capacitors and resistors, inductors are one of the three passive linear circuit elements that make up electronic circuits.
Iron core inductor: This inductor is used when greater value of inductance has to be generated. A iron material is wound with the wire(the coil) and iron being a magnetic material gets magnetized itself hence more flux is generated and it is not lost.
In iron powder cores saturation flux densities of more than 1 T can be utilized, depending on the material. As you mentioned Micrometals core: Micrometals, Inc. offers an Inductor Design Software that can be used to design basic inductors including power loss calculations.
Resistors designed specifically for use at high frequencies are made of metal film, to avoid creating the coil shape and reduce the parasitic inductance. Reactance and inductance calculations In AC circuits, Electrical impedance is the measure of the opposition that a circuit presents to the passage of a current when a voltage is applied.

Applications for Multilayer Inductors: Multilayer Inductors can be used in mobile communication systems and applications that require noise suppression at high frequency and impedance matching.
Toroidal inductors and transformers are inductors and transformers which use magnetic cores with a toroidal (ring or donut) shape. They are passive electronic components, consisting of a circular ring or donut shaped magnetic core of ferromagnetic material such as laminated iron, iron powder, or ferrite, around which wire is wound.
Self Resonant Frequency (SRF) describes the frequency at which an inductor stops working as an inductor. For RF circuits, self resonant frequency should be chosen such that it exceeds the operating frequency of the circuit. As the inductance is zero at the self resonant frequency, the Q factor is zero.
