RM065-503(50KΩ)是博晨(BOCHEN)品牌推出的经济型插件可调电位器,核心面向对精度要求适中、成本敏感的小型电子电路设计。该产品属于基础型电位器范畴,通过旋转调节实现电阻值连续变化,适配小家电、简易仪器等场景的分压、限流或信号微调需求,无需复杂校准即可满足日常使用。
标称阻值为50kΩ,采用行业通用的三位数字编码标识(503):前两位“50”为有效数字,第三位“3”表示10的3次方(即50×10³=50kΩ),编码规则与国际标准一致,便于快速识别。
精度为**±25%**,属于工业级通用精度,无需高精度校准即可满足大部分基础调节场景(如非精密仪器的电压微调),适合对成本敏感的批量应用。
额定功率100mW(0.1W),对应最大允许电流约1.41mA(计算方式:(I=\sqrt{P/R}=\sqrt{0.1/50000}≈1.41mA))。使用时需避免长期过载(如电流超过1.5mA可能导致电阻体发热老化)。
额定电压50V(直流/交流有效值),适配低电压电路(如5V、12V、24V系统),超出额定电压可能引发绝缘击穿,需注意电路设计中的电压限制。
采用插件式封装(行业内RM065系列多为3脚立式/卧式插件,兼容常规PCB焊接工艺),无需特殊设备,普通电烙铁即可完成安装,适配性强。
RM065-503采用小型化紧凑结构,核心组件包括:
体积约为φ6mm×8mm(具体以实际产品为准),便于在空间有限的电路中布局,适合小型化产品设计。
该产品凭借“低成本、易安装、适配性强”的特点,成为基础电子电路中分压/微调的优选元件,适合对精度要求不高的批量应用场景。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.
The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
