3296X-1-102 可调电位器产品概述

一、产品基本定义与型号解读

3296X-1-102属于多圈精密可调电位器,是BOCHEN(博晨)品牌针对中低功率、高精度调节场景设计的插件式元器件。型号各部分含义明确:

  • 3296X:代表多圈精密电位器系列,区别于单圈电位器(如3296W),核心特征是精细调节能力;
  • 1:对应额定功率0.5W(500mW),适配小型电路的功率需求;
  • 102:阻值编码,遵循“数字×10^n”规则,即10×10²=1000Ω=1kΩ;
  • 后缀隐含精度(±10%)、封装(插件)等参数,与基础参数一致。

二、核心技术参数详解

该电位器参数均衡,覆盖多数常规电子电路需求:

  1. 阻值与精度:标称1kΩ,精度±10%,实际阻值范围900Ω~1100Ω,满足一般校准、分压电路的基本精度要求;
  2. 功率特性:额定功率500mW(持续负载),短时间峰值功率可至1W(需注意散热,避免过热);
  3. 温度系数:±250ppm/℃,即温度每变1℃,阻值变化±0.025%(如25℃时1kΩ,100℃时约1018.75Ω),适合环境温变≤50℃的场景;
  4. 调节圈数:30圈多圈调节,相比单圈(1圈)分辨率提升30倍,可实现精细阻值微调;
  5. 封装形式:插件直插引脚,间距符合标准PCB设计,便于手工焊接或自动化插件,兼容性强。

三、产品结构与工艺特点

采用成熟精密结构,确保性能稳定:

  • 电阻体:玻璃釉电阻体附着于陶瓷基体,耐高温(-55℃~125℃)、抗老化,阻值稳定性优于碳膜电位器;
  • 调节机构:多圈螺纹轴,旋转30圈完成全阻值调节,轴端带十字槽(部分型号为一字槽),便于螺丝刀微调;
  • 密封设计:轴部橡胶密封圈(部分型号),防止灰尘、湿气侵入,延长寿命(典型≥10000次调节);
  • 引脚处理:镀锡引脚,焊接性好、抗氧化,避免虚焊问题。

四、典型应用场景

因参数适配性强,广泛用于:

  1. 工业控制:PLC模拟量输入校准、小型电机调速器基准调节、传感器信号调理;
  2. 消费电子:音响音调(高低音)微调、LED驱动电流限流、电磁炉/加湿器功率调节;
  3. 仪器仪表:万用表量程校准、示波器增益微调、实验室电源电压基准调节;
  4. 通信设备:小型基站信号衰减调节、路由器电源模块电压微调。

五、选型与使用注意事项

  1. 选型匹配:若需更高精度(±5%)、更大功率(1W)或更小阻值(100Ω),选3296X系列其他型号(如3296X-1-101、3296X-2-102);
  2. 焊接规范:温度≤260℃,焊接时间≤3秒,用无铅焊料(符合RoHS),避免过热损坏电阻体;
  3. 调节限制:不超30圈调节范围(防机械过载),调节后可通过锁固机构(部分型号)固定阻值;
  4. 存储条件:干燥通风环境,温度-40℃~85℃,湿度≤80%RH,避免阳光直射或腐蚀性气体。

六、品牌与可靠性说明

BOCHEN(博晨)是国内电位器专业品牌,产品通过RoHS、CE认证,批次一致性好(实际阻值偏差≤±8%,优于标称±10%)。该型号已批量应用于国内多家电子厂商,反馈可靠性良好,适合批量采购。

该产品以“多圈精细调节+中等功率适配”为核心优势,是常规电子电路中阻值微调的高性价比选择。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
