3386P-1-502是博晨(BOCHEN)品牌推出的一款插件式通用可调电位器,主打性价比与实用型,广泛适配消费电子、工业控制、仪器仪表等领域的阻值微调需求。以下从核心信息、参数解析、结构特点、应用场景等维度展开详细介绍。
该产品属于单圈旋转可调电阻,采用标准插件(直插)封装,无需特殊贴装设备即可完成焊接,适合原型开发、小批量生产及传统电路板设计。型号编码解析:
标称阻值为5kΩ,精度等级±10%,即实际阻值范围在4.5kΩ~5.5kΩ之间,满足大多数非超高精度电路的微调需求(如普通信号校准、电压分压调整等)。
最大允许功耗为500mW(0.5W),工作时需严格控制实际功耗:
温度系数为**±250ppm/℃**,表示环境温度每变化1℃,阻值变化约±0.025%(250×10⁻⁶)。在常规工作温度(-55℃~125℃)范围内,阻值稳定性可满足一般应用场景(如室内电子设备、普通工业环境)。
采用标准插件封装,引脚间距符合行业通用标准(通常2.54mm),便于手工焊接或波峰焊;产品尺寸约为直径10mm、高度6mm,小型化设计可有效节省电路板空间。
电阻体采用碳膜材质(部分批次为金属陶瓷),阻值分布均匀,旋转调节时手感顺滑无卡顿;单圈设计(0360°旋转)可实现连续阻值调节,调节范围覆盖标称阻值的0100%。
插件封装适配多种电路板工艺,无需SMT贴装设备,降低生产设备成本;5kΩ阻值为电子电路常用分压、限流规格,应用场景覆盖广泛。
综上,3386P-1-502可调电位器以高性价比、便捷调节、可靠性能为核心优势,是通用电路中阻值微调的优选元件,可满足多数常规电子设备的设计与生产需求。

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.
