The Characteristics of 3296 Potentiometers | Xtalong
1. 3296 potentiometers y factor: We use Q to represent, 3296 potentiometer adjustable resistance quality factor Q represents the coil quality, and the value of Q is equal to the ratio of the inductive reactance XL to its equivalent resistance, namely: Q=XL/R. That is to say, the higher the Q value of the coil, the smaller the loss of the loop; The Q value of the coil is related to the DC resistance of the wire, the dielectric loss of the skeleton, the loss caused by the shield or the iron core, and the influence of the high-frequency skin effect.
2. 3295 potentiometers Scatter capacitance: that is, the capacitance between the coil and the shield, the turn-to-turn spacing, and the coil and the plate, The existence of scattering capacitance reduces the Q value of the coil and deteriorates the stability, so the smaller the scatter capacitance of the coil, the better.
3. 3296 potentiometers Inductance: We use the letter L to represent it. L is the inherent characteristic of the coil itself and has nothing to do with the current. Except for the special inductance coil, the inductance is generally not marked on the coil, but marked with a specific title.
4. 3296 potentiometers Inductive reactance: We use XL to represent, that is, the size of the effect of the coil on the AC current barrier, in Ω, the relationship between it and the chip inductance L and the AC frequency f is XL=2πf.
