Air core coil
Product Advantages
-
01
Inductance
lower (compared to iron core coils), but can be increased by increasing the number of turns or coil area.
-
02
Quality factor (Q value)
Q value is higher at high frequencies (no iron core eddy current loss), suitable for radio frequency (RF) applications.
-
03
Distributed capacitance
Coil turn-to-turn capacitance may affect high-frequency performance, and winding spacing needs to be optimized.
-
04
Resistance
Determined by wire material and length, DC resistance (DCR) affects energy consumption.
Excellent high-frequency performance: no iron core loss, suitable for RF and microwave circuits.
No magnetic saturation: stable inductance under high current, suitable for pulse and high dynamic scenarios.
Lightweight: simple structure, light weight, low cost.
Disadvantages:
Low inductance: the inductance value is much smaller than that of iron core coils at the same volume.
Weak magnetic field strength: requires larger current or more turns to generate the same magnetic field.
Typical application scenarios
