Sunlord Chip inductor
Terms and Descriptions
L (Inductance):
The property of a circuit element which tends to oppose any change in the current flowing through it. The inductance for a given inductor is influenced by the core material, core shape and size. the turns count and the shape of the coil. Inductors most often have their inductances expressed in microhenries (μH).
1 millihenry (mH) = 10-3 H1 microhenry (μH) = 10-6 H1 nanohenry (nH) = 10-9 H
Inductance Tolerance:
Standard inductance tolerances are typically designated by a tolerance letter.
LETTER TOLERANCEC ±0.2nHD ±0.5nHF ±1%G ±2%H ±3%J ±5%K ±10%S ±0.3nH
Sunlord Chip inductor
Terms and Descriptions
Q (Quality Factor):
The Q value of an inductor is a measure of the relative losses in an inductor. The Q is also known as the "quality factor" and is technically defined as the ratio of inductive reactance to effective resistance and is represented by:
Since XL and Re are functions of frequency, the test frequency must be given when specifying Q.XL typically increases with frequency at a faster rate than Re at lower frequencies, and vice versa at higher frequencies. This results in a bell shaped curve-for Q vs frequency.Re is mainly comprised of the DC resistance of the wire, the core losses and skin effect of the wire.Based on the above formula, it can be shown that the Q is Zero at the self resonant frequency since the inductance is Zero at this point.
Sunlord Chip inductor
Terms and Descriptions
SRF (Self-resonant Frequency):
The frequency at which the inductor's distributed capacitance resonates with the inductance. it is at this frequency that the inductance is equal to the capacitance and they cancel each other.The inductor will act purely resistive with a high impedance at the SRF point.The distributed capacitance is caused by the turns of wire layered on top of each other and around the core.This capacitance is in parallel to the inductance.At frequencies above the SRF, the capacitive reactance of the parallel combination will become the dominant component.Also, the Q of the inductor is equal to zero at the SRF point since the inductive reactance is zero.The SRF is specified in MHz and is listed as a minimum value on product data sheets.
Sunlord Chip inductor
Terms and Descriptions
DCR (DC Resistance):
The resistance of the inductor measured with direct current. The DCR is most often minimized in the design of a inductor.The unit of measure is ohms and it is usually specified as a maximum rating.
IDC (Rated Current):
The level of continuous DC current that can be passed through the inductor.This DC current level is based on a maximum temperature rise of the inductor at the maximum rated ambient temperature. The rated current is related to the inductor's ability to minimize the power losses in the winding by having a low DC resistance. It is also related to the inductor's ability to dissipate this power lost in the winding. Thus, the rated current can be increased by reducing the DC resistance or increasing the inductor size.
