## 电气工程师工具箱 Description
设计更快，即时检查公式，获得可靠答案——无论你是在连接原型、设计PCB，还是验证实验结果。这个一体化工具包汇集了最常用的电子计算器，让你无需在应用或表格之间切换。

核心电路与无源元件
• 欧姆定律 (V, I, R, P)
• 电阻色环码（直插与SMD）
• 串联/并联与分压器
• 电容与电容阻抗 (RC)
• 电感/感抗/导纳；线圈/回路电感
• 电池寿命估算
• 有效值/峰值/峰峰值电压
• 分贝 (dB) 功率/电压换算

模拟与射频基础
• 运算放大器增益/电压及反相电阻计算器
• 阻抗匹配：π匹配和T匹配
• 射频功率：比率/单位换算、PAE、N路功率分配器
• dB/dBm 工具，用于快速链路预算计算
这些是工程师日常模拟与射频工作中依赖的工具。

PCB 与信号完整性 (EDA)
• 微带线/带状线阻抗（单端与差分）
• 走线宽度与最大电流
• 串扰（边缘/重叠）、导线/微带线电感
这些功能与专业PCB工具包和在线阻抗计算器相同——现在在手机上一站式拥有。

机电与电源
• 楞次定律与法拉第定律（感应电动势）
• 转矩换算与步进电机辅助工具
• 反激式开关电源（SMPS）基础模块
• 散热器基础与功率密度
• 峰值/峰峰值/有效值与功率换算
这些工具连接了实验室计算与实际硬件选择之间的桥梁。

物理与基础
• 洛伦兹力、电能、RC时间常数、LC谐振——实验与考试中实用的快速检查。

为什么选择这个应用？
• 全面：从欧姆定律和电阻色环到PCB阻抗和射频功率——覆盖工程师日常真正使用的工具。
• 为速度而生：清晰输入，明确结果，单位符合习惯。
• 面向所有人：学习基础的学生、快速迭代的创客，以及验证设计的专业人士。

完美适用：电子实验室、现场服务、业余/射频项目、PCB布局检查、音频/dB工作，以及评审时快速的“理智检查”计算。
