b.状态晶体管以日本生产的为多,各厂的型号各异,常见状态晶体管的外形及内部电路如图11所示。④贴片场效应管:与贴片晶体管相比,贴片场效应管具有输入阻抗高、噪声低、动态范围大、交叉调制失真小等特点。贴片场效应管分结型场效应管(JFET)和绝缘栅场效应管(MOS-FET)。JFET主要用于小信号场合,MOSFET既有用于小信号场合,也有用于功率放大或驱动的场合。贴片场效应管的外形及引脚排列如图12所示(两种不同排列)。
b. Status Transistors Mostly produced in Japan, the models vary from one plant to another. The shape and internal circuit of common state transistors are shown in Figure 11. ④ SMD FET: SMD transistor compared with the SMD FET with high input impedance, low noise, large dynamic range, cross-modulation distortion and so on. Chip FET Junction Field Effect Transistor (JFET) and Insulated Gate Field Effect Transistor (MOS-FET). JFET is mainly used for small signal applications, MOSFETs are used for small signal applications, but also for power amplification or drive applications. SMD FET shape and pin arrangement shown in Figure 12 (two different arrangements).
