Differences of PC40 and PC95

PC40 and PC95 are naming conventions for magnetic core materials by TDK. Their differences are mainly reflected in the following aspects:

PC40和PC95是TDK公司对磁芯材料的命名，它们的区别主要体现在以下几个方面 ：

• Permeability: The initial permeability of PC40 is generally around      2200–2300, while that of PC95 is 3300. With a higher permeability, PC95      can provide a stronger magnetic field strength under the same number of      coil turns and dimensions.

- 磁导率：PC40的初始磁导率一般在2200-2300左右，而PC95的初始磁导率为3300，PC95磁导率更高，意味着在相同的线圈匝数和尺寸下，PC95磁芯能够提供更强的磁场强度。

• Core Loss: Under conditions of      100°C, 100 kHz, and 200 mT, the core loss of PC40 is 420 kW/m³, whereas      that of PC95 is 290 kW/m³. PC95 has lower core loss, which helps reduce      heat generation and improve energy conversion efficiency.

- 磁芯损耗：在100℃、100kHz、200mT的条件下，PC40的磁芯损耗为420kW/m³，PC95的磁芯损耗为290kW/m³，PC95的磁芯损耗更低，能有效减少发热，提高能源转换效率。

• Saturation Magnetic Flux Density: At      25°C, the saturation magnetic flux density of PC40 is 510 mT, and that of      PC95 is 530 mT; at 100°C, PC40’s is 380 mT, and PC95’s is 410 mT. PC95 has      a relatively higher saturation magnetic flux density and experiences a      smaller change with temperature.

- 饱和磁通密度：在25℃时，PC40的饱和磁通密度为510mT，PC95为530mT；在100℃时，PC40的饱和磁通密度为380mT，PC95为410mT。PC95的饱和磁通密度相对较高，且随温度变化的幅度较小。

• Curie Temperature: The      Curie temperature of PC40 is greater than 200°C, while that of PC95 is      greater than 215°C. With a higher Curie temperature, PC95 offers better      thermal stability.

- 居里温度：PC40的居里温度大于200℃，PC95的居里温度大于215℃，PC95的居里温度更高，其热稳定性更好。

• Price: Since PC95 has superior performance compared to PC40, its      price is also relatively higher.

- 价格：PC95的性能优于PC40，其价格也相对较高。
