3296W-1-500 多圈可调电位器产品概述

3296W-1-500是博晨(BOCHEN)品牌推出的插件式多圈可调电位器,属于3296W系列精密可调电阻范畴,核心用于电路参数的精细调节,兼顾稳定性与性价比,适用于工业控制、仪器仪表、电源电路等多类场景。

一、产品基本属性

该产品为单联多圈电位器,采用插件封装形式(3引脚带定位脚设计),属于工业级通用型可调电阻。其核心功能是通过旋转调节内部电阻体的接触位置,实现阻值在0~50Ω范围内的连续变化,满足电路中电压、电流、增益等参数的校准需求。

二、核心电气性能解析

  1. 阻值与精度:标称阻值50Ω,精度等级±10%(实际阻值范围45Ω~55Ω),符合工业级电路的通用精度要求,无需额外高精度校准即可满足多数基础应用。
  2. 功率特性:额定功率500mW(0.5W),该参数为25℃环境温度下的最大值,实际使用中需注意温度对功率的影响(温度每升高10℃,功率需降额约10%)。
  3. 温度系数:±250ppm/℃,表示温度每变化1℃,阻值变化量为0.025%(如温度从25℃升至55℃,阻值变化约0.375Ω),属于中等稳定型温度系数,适用于对温度漂移要求不苛刻的场景。
  4. 调节圈数:30圈多圈设计,总调节角度达10800°,每圈阻值变化约1.67Ω(50Ω÷30),相比单圈电位器的调节分辨率提升30倍,可精准实现电路参数的微调。

三、机械结构与封装特性

  • 封装形式:插件式3引脚结构,带定位脚(用于PCB板固定,避免焊接后移位),引脚间距符合标准插件焊盘尺寸,兼容常规PCB设计。
  • 尺寸规格:参考3296W系列标准参数,产品直径约6mm,高度约10mm,结构紧凑,可适配空间受限的电路布局(如小型仪器、便携式设备)。
  • 调节方式:侧面十字螺丝刀调节,操作便捷,多圈结构可避免单圈调节时的“过冲”问题,调节过程平滑稳定。

四、典型应用场景

  1. 电源电路校准:线性电源、开关电源的输出电压微调(如反馈分压电路调节),确保输出电压稳定在目标值。
  2. 信号调理电路:传感器(压力、温度、光电传感器等)的零点/量程校准,运放电路的增益、偏置电压调整。
  3. 仪器仪表标定:万用表、示波器、信号发生器等设备的精度校准,提升测量数据准确性。
  4. 工业控制:PLC、变频器、伺服系统的辅助参数设置(如死区电压、增益系数调节),适配不同工况需求。
  5. 消费电子:音频设备的音量平衡调节、显示设备的亮度/对比度微调等(需匹配低阻抗电路需求)。

五、选型与使用注意事项

  1. 功率降额:环境温度超过25℃时,需按降额曲线使用(如70℃时额定功率降额至0.3W),避免电阻过热损坏。
  2. 焊接工艺:焊接温度建议不超过260℃,单次焊接时间≤3秒,避免高温损坏电阻体或引脚。
  3. 调节限制:机械寿命约1000次调节(3296W系列标准),避免频繁调节导致接触磨损,影响阻值稳定性。
  4. 阻值匹配:50Ω阻值适用于中低阻抗回路(如≤1kΩ电路),不建议用于高阻抗精密电路(如兆欧级信号调理)。

六、品牌与品质保障

博晨(BOCHEN)作为国内专注于电位器领域的品牌,3296W-1-500产品符合RoHS环保标准,出厂前经过阻值校准、绝缘电阻测试(≥100MΩ)等工序,批量一致性好,可满足工业级与民用级电路的批量生产需求。

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
