BOCHEN博晨3362S-1-103是一款插件式可调电位器,聚焦低功耗电路的参数动态调节需求,以10kΩ标称阻值、500mW额定功率为核心性能,适配消费电子、工业控制等多场景。以下从核心属性、性能参数、应用优势等维度详细解析:
类型定位
属于可调电阻/电位器范畴,通过机械调节改变自身阻值,实现电路电压、电流、增益等参数的灵活调整,区别于固定电阻的阻值不可变性。
品牌与型号标识
封装形式
采用插件式(Through-Hole) 封装,金属插针设计适配通孔电路板,无需表面贴装设备,手工/批量焊接均便捷,抗振动性能优于贴片封装。
阻值与精度
额定功率
25℃环境下额定耗散功率为500mW(0.5W),是电位器长期稳定工作的最大功率阈值。若环境温度升高(如85℃),需按降额曲线降低功率(常规每升高10℃降额5%,85℃时最大允许功率约300mW)。
温度系数
阻值温度系数为**±250ppm/℃,表示每变化1℃,阻值相对变化量为百万分之250。例如:
25℃时阻值10kΩ,温度升至100℃(变化75℃),阻值变化量=75×250ppm×10kΩ=18.75Ω,实际阻值范围为9981.25Ω~10018.75Ω**,温度稳定性适配普通工业/消费场景。
工作温度范围
常规适配**-40℃~+85℃**,可覆盖户外、车间等不同环境温度需求。
高性价比适配
博晨品牌定位中端,3362S系列兼顾性能与成本,无需承担高精度电位器的溢价,适合量产项目(如小家电)或DIY实验。
可靠性耐用性
调节便捷性
采用顶部螺丝刀调节方式,无需额外旋钮,适配紧凑电路设计;调节精度满足多数场景(如音量调节、信号分压)。
兼容性广
插件封装适配各类通孔电路板,可与普通电阻、电容并联/串联,无需特殊电路适配。
消费电子领域
工业控制与仪器
电子教学与DIY
功率过载防护
避免耗散功率超过500mW(25℃),例如:若电位器两端电压10V,最大允许电流为50mA(I=P/U=0.5W/10V),需确保电路电流不超限。
焊接规范
电烙铁温度≤260℃,焊接时间≤3秒,避免高温损坏电阻体;焊接后清理引脚焊锡,防止短路。
精度适配
若电路需±1%以上精度(如精密仪器),需更换高精度电位器型号,避免影响性能。
调节次数限制
避免每秒多次调节,否则加速内部磨损,降低使用寿命。
博晨3362S系列符合RoHS 2.0环保标准(无铅、无镉),批量供货一致性好;若出现质量问题,可通过品牌售后渠道退换,保障项目进度。
综上,BOCHEN博晨3362S-1-103插件电位器以实用性能、高性价比为核心,是消费电子、工业控制与DIY领域的可靠选择。
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.
