查询词典 uranium nitrate

For close coordination and continuous product development to meet the customers needs, I have launched a series of the Division for surface mount MELF resistors, also known as wafer resistance, columnar resistance or non-lead resistance and so on, including the ultra-sophisticated, ultra-low temperature coefficient of RJM series, ultra-high resistance, high operating voltage of the RGM uranium metal film resistors.

为紧密配合和持续满足用户产品开发需要，我司推出了一系列用於表面贴装的 MELF 系列电阻，也称为晶圆电阻、柱状电阻或无引线电阻等，其中包括超高精密，超低温度系数的 RJM 系列，超高阻值，超高工作电压的 RGM 金属铀膜电阻器。
