BOCHEN 3296X-1-503 精密可调电位器产品概述

一、产品定位与核心特性

BOCHEN(博晨)3296X-1-503属于工业级精密多圈可调电位器,是电路中实现精确阻值/电压微调的核心元件。该型号以30圈多圈调节为核心设计,结合500mW功率耐受、±10%精度及±250ppm/℃温度系数,兼顾了调节精度与实用可靠性,可替代单圈电位器解决“调节幅度过大、参数易超调”的问题,适用于仪器校准、电源微调、工业控制等场景。

二、关键技术参数详解

该型号参数针对工业应用优化,核心指标清晰明确:

  1. 阻值规格:标称阻值50kΩ,采用“503”标识(50×10³Ω),符合电子元件阻值标注规范,便于电路设计快速识别;
  2. 精度等级:±10%工业级精度,满足多数仪器校准、控制电路的参数稳定性需求,无需额外高精度补偿;
  3. 功率额定值:最大耐受功率500mW(0.5W),实际工作时需避免过载(计算公式:(P=U^2/R=I^2R)),长期过载会导致电阻体过热烧毁;
  4. 温度系数:±250ppm/℃,即温度每变化1℃,阻值漂移±12.5Ω((250×10^{-6}×50kΩ)),可适应-40℃至+85℃的常规工作温度;
  5. 调节圈数:30圈多圈调节,从最小阻值(接近0Ω)到最大50kΩ需旋转30圈,每圈调节阻值约1.67kΩ,调节分辨率远高于单圈电位器;
  6. 封装形式:插件(直插)3脚封装(2固定端+1滑动端),便于焊接PCB板,安装后抗振动性能稳定。

三、结构设计与封装特点

3296X系列采用金属陶瓷电阻体(比碳膜更耐磨、稳定),内部通过齿轮传动实现30圈线性调节:旋转轴带动滑动触点沿电阻体表面滑动,齿轮比设计确保调节线性度与精度。外部为塑料防护外壳,轴端带十字调节槽(需螺丝刀操作),封装尺寸约6mm×6mm×10mm,引脚镀锡处理,焊接附着力强,兼容常规PCB布局。

四、典型应用场景

该型号因参数匹配性强,广泛应用于以下领域:

  1. 工业控制:PLC、变频器的模拟量偏置校准,伺服系统反馈增益微调;
  2. 仪器仪表:示波器垂直增益校准、信号发生器输出幅度调节、万用表零点校准;
  3. 电源电路:线性电源输出电压微调(如12V电源精度校准)、开关电源电流限制调节;
  4. 音频设备:调音台通道增益微调、功放偏置电压调节(需匹配电路阻抗);
  5. 通信设备:基站中低频段阻抗匹配微调、调制解调器信号幅度调节。

五、使用注意事项

为保障性能与寿命,需注意以下细节:

  1. 功率限制:实际功耗≤500mW,例如两端电压≤158V((U=\sqrt{0.5×50000})),避免长期过载;
  2. 调节操作:用适配螺丝刀调节,禁止过度旋转(超30圈会损坏齿轮);
  3. 温度补偿:若环境温度变化超±20℃,需考虑阻值漂移对电路的影响;
  4. 焊接规范:烙铁温度≤300℃,焊接时间≤3秒,避免高温损坏电阻体;
  5. 储存条件:未使用产品储存在干燥通风处(-55℃~+125℃,湿度≤80%),避免阳光直射。

BOCHEN 3296X-1-503以高性价比的精密调节性能,成为工业与电子领域替代进口同类产品的可靠选择,满足多数常规微调场景需求。

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
