BOCHEN(博晨)3296X-1-502是一款插件式多圈精密可调电位器,属于3296X系列通用型产品,核心参数匹配5kΩ阻值、±10%精度、500mW功率等要求,广泛适用于电子仪器、电源调节、工业控制等场景,兼顾调节精度与成本优势。
3296X-1-502定位为通用型多圈可调电位器,区别于单圈电位器的粗略调节,其30圈设计可实现更精细的阻值设置;插件封装无需特殊贴片设备,适合传统PCB批量焊接,是替代单圈电位器提升调节精度的性价比选择。基础属性如下:
额定功率500mW(0.5W),需注意温度降额:环境温度每升高10℃,最大允许功耗降低50%(如65℃时最大功耗250mW),避免电阻体过热老化。
±250ppm/℃表示:每变化1℃,阻值变化百万分之250。以25℃为基准,若温度升至75℃(变化50℃),阻值变化量为5000Ω×50×250e-6=62.5Ω,实际范围4937.5Ω~5062.5Ω,稳定性满足一般环境需求。
30圈多圈调节,分辨率是单圈的30倍(最小步长≈5000Ω/30≈167Ω),避免调节过冲,适合精细设置(如示波器通道增益)。
3296X-1-502采用金属陶瓷电阻体,结构优势明显:
BOCHEN产品出厂前经阻值精度、功率老化、温度特性测试,批次一致性达标,符合RoHS环保标准。
结合参数特性,适用于以下场景:
BOCHEN 3296X-1-502是性价比突出的通用多圈电位器,兼顾30圈精度、500mW功率与成本,插件封装适配传统PCB,广泛用于电子仪器、工业控制、家电等领域。参数稳定、安装方便,是替代单圈电位器提升调节精度的理想选择。

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.
