1.Open Circuit Inductance (OCL) Test Parameters: 100kHz, 0.25Vrms, 0.0Adc,+25°C

初始电感测试条件: 100kHz, 0.25Vrms, 0.0Adc,+25°C

2.Full Load Inductance (FLL) Test Parameters: 100kHz, 0.25Vrms, Isat, @ +25°C

叠加电感测试条件: 100kHz, 0.25Vrms, Isat, @ +25°C

3.Irms: DC current for an approximate temperature rise of 40°C without core loss. Derating is

necessary for AC currents. PCB layout, trace thickness and width, air‐flow, and proximity of

other heat generating components will affect the temperature rise. It is recommended that the

temperature of the part not exceed 125°C under worst case operating conditions verified in the

end application

温升电流：引起磁芯温度上升 40°时的直流电流。PCB 布局，轨道的厚度和宽度，气流

和其他相邻的发热元件性都会影响温度上升。在终端应用时建议最恶劣条件下的温度

不超过 125°C

4.Isat: Peak current for approximately 20% rolloff at +25°C

饱和电流：峰值电流下的电感跌落接近 20%

5.K‐factor: Used to determine Bp‐p for core loss (see graph). Bp‐p = K × L × I.Bp‐p: (Gauss), K:

(K‐factor from table), L: (Inductance in μH), I (Peak to peak ripple current in amps)

系数 K：用来计算 Bp‐p, Bp‐p = K × L × I

Bp‐p: (单位 Gauss), K: (见表格), L: (电感 μH), I (峰‐峰值电流 A)

6.Part Number Definition: DCY0520‐yyy‐R

‐ DCY0520 = Product code and size

‐ yyy= Inductance value in μH, R = decimal point,

if no R is present then third character = number of zeros.

“‐R” suffix = Material of powder (YT35、YG50)

型号定义：DCY0520‐yyy‐R

‐ DCY0520 = 产品代码

‐ yyy= 电感值 μH, R =小数点,如果没有小数点存在，那么第三个字符等于 0

“‐R” 后缀 = 所用的粉料材质 (YT35、YG50)

Dimensions 结构尺寸（mm）

Top View Side View Bottom View Recommended Pad Layout Schematic

Part Marking: xxx = Inductance value in μH, R = decimal point, if no R is present, third character = number of zeros,

wly = (Date Code，w is bi‐weekly letter code, l is manufacturing location code, y is the last number of year), R = (Revision Level)

All soldering surfaces to be coplanar within 0.10 millimeters.

Tolerances are ±0.3 millimeters unless stated otherwise.

Color of coating: Top Side Grey coating.
