功率能力：额定功率通常为10W,部分型号在无散热条件下可达更高功率(如PBV-R470-F1-0.5的脉冲功率为2J/10ms).

精度与温漂：容差为±0.5%或±1%,温度系数(TCR)低至50ppm/K,部分型号可达30ppm/K.

封装与安装：采用TO-247类似封装,4引脚设计,适合PCB安装,优化散热性能.

应用领域：主要用于电机控制\变频技术\大功率开关电源及汽车电子(如BMS系统).

优势

高脉冲负载能力：适合瞬时高电流场景.

长期稳定性：偏差极小,适用于精密电路.

耐高温焊接：可承受350°C焊接温度,适合自动化生产.

2. PBH 系列电阻

技术特点

阻值范围：典型型号如PBH-2R70-F1-1.0(2.7Ω)和PBH-R100-F1-0.5(100mΩ),覆盖毫欧至欧姆级.

功率能力：标称功率3W,无散热片时负载能力可达10W.

精度与温漂：容差±0.5%或±1%,TCR为50ppm/K.

封装与安装：径向设计,带中心安装孔和大底板,优化传热(类似TO-247结构).

应用领域：工业电源\汽车电子(如电机驱动\BMS)及高精度测量设备.

优势

散热设计：大底板和安装孔提升热管理效率.

高可靠性：通过ISA-PLAN工艺实现低TCR和高稳定性.

模块化兼容性：适合高密度电路布局.

3. 对比总结

4. 选择建议

PBV系列：适合需要高脉冲负载和紧凑封装的场景(如开关电源).

PBH系列：适用于需优化散热的持续高功率应用(如汽车BMS)
