【产品】散热好+底部可布线的BVR系列汽车级表面贴装高功率精密电阻新增BVR-V-R002产品
距离上一份BVR系列2013年的产品规格书,大家使用至今。2019年01月,ISABELLENHUETTE对BVR系列汽车级毫欧级表面贴装精密电阻产品规格书做了更新。
BVR-V-R002表面贴装精密电阻实物图
ISABELLENHUETTE增加了BVR-V-R002产品,这是基于ISABELLENHUETTE的Noventin® 合金的新产品。如同BVT和BVS系列一样,使Isa-weld®产品家族在2mohm这一阻值段上有了一个新的选择,可用于混合动力应用的电流传感器、汽车市场的高电流应用、变频器和电源模块等场合。
此外,在BVR系列数据手册更新版中,标注了P70°C 和P100°C 下的额定功率,方便工程师在不同的使用环境下进行功率设计。
伊莎贝棱辉特公司依然是唯一在规格书中标注出Rthi(热内阻)的厂商。通过查表中的Rthi参数,帮助设计者得到所需要的功率。
如:BVR-Z-R0005 , 端子温度5W。
TK = Tmax (170°C) - (Rthi x P) TK= 170°C- (8 K/W x 5W) = 130°C.
该公式表示BVR-Z-R0005在即使端子温度是130°C下依然可以负载5W的额定功率。
值得一提的是,2019年3月20-22日,ISABELLENHUETTE将在上海新国际博览中心举行的慕尼黑上海电子展中,在E4 号馆4708展位举行精密电阻、精密模块、精密合金的讲座,想要了解的工程师,届时可前往ISABELLENHUETTE的4708展位进行交流。收藏此文章并到场出示,即可获得精美礼品一份。
