RM065-504是博晨(BOCHEN)品牌推出的经济型插件式可调电位器,主打中小功率、通用场景的电阻调节需求,凭借成本优势与安装便捷性,广泛应用于消费电子、工业控制等低精度调节领域。
该电位器核心定位为**“低精度、高适配性的通用电阻调节工具”**,兼顾可靠性与成本控制,基本属性如下:
关键参数明确了产品的适用边界,具体解析如下:
标称阻值500kΩ属于中高阻值范围,适配信号衰减、分压电路等需要高阻调节的场景;±25%精度意味着实际阻值允许存在较大偏差,需避免用于需要精确校准的电路。
额定功率是电位器允许的最大连续功耗,超过该值会导致内部电阻体过热损坏。结合阻值计算,最大允许电流约为:
[ I_{\text{max}} \approx 447,\mu\text{A} ]
实际使用中需避免电流超过该阈值。
额定电压是电位器两端允许施加的最大直流/交流电压有效值,需与功率同时满足(如施加50V电压时,实际功耗仅5mW,远低于额定功率),主要需避免过压击穿内部结构。
采用通孔焊接封装,引脚间距适配常规PCB板,支持手工焊接或自动化插件设备,安装便捷性高,无需特殊焊接工艺。
RM065-504的核心优势集中在“成本、便捷性与适配性”:
结合参数特性,该电位器的典型应用集中在低精度、中小功率调节场景:
为确保产品可靠性,使用时需注意以下几点:
综上,RM065-504(500KΩ)电位器是一款性价比突出、安装便捷的经济型可调电阻,适合对精度要求不高、需要快速实现电阻调节的通用场景,是消费电子、工业控制、教学实验等领域的实用选择。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
