BOURNS 3296Y-1-101LF 精密可调电位器产品概述

一、产品核心身份与定位

BOURNS 3296Y-1-101LF 是一款多圈精密可调电位器(又称预设电位器),隶属于 BOURNS 经典的 3296 系列。该产品以小型化封装、精准调节能力为核心特点,主要面向需要稳定电阻值预设、且对空间要求苛刻的电子设备设计,是仪器仪表、电源电路、工业控制等领域的常用元件。

二、关键电气参数详解

该电位器的核心参数直接决定了其应用范围,具体解析如下:

1. 阻值与精度

  • 标称阻值:100Ω(型号中“101”编码对应“10×10¹=100Ω”,前两位为有效数字,第三位为10的幂次);
  • 精度:±10%(允许阻值偏差范围为90Ω~110Ω),属于工业级常规精度,满足大部分非超高精度场景需求。

2. 功率与温漂特性

  • 额定功率:500mW(0.5W),即正常工作时电阻功耗不得超过0.5W(若超过会导致阻值漂移、内部元件老化甚至烧毁);
  • 温度系数:±100ppm/℃(“ppm”为百万分之一,即温度每变化1℃,阻值变化±0.01%)。该参数反映了温度变化对阻值的影响,适合环境温度波动较小的场景(如室内设备)。

3. 调节分辨率

  • 圈数:25圈(多圈设计),相比单圈电位器(通常1圈),调节分辨率提升25倍——每圈可调节阻值约4Ω,能更精准地定位目标电阻值,避免“过调”问题。

三、物理封装与安装特性

该产品采用插件式3引脚封装,具备以下结构优势:

1. 尺寸与布局

  • 外形尺寸:9.5×4.8mm(长×宽),属于小型化设计,可节省PCB板空间,适配紧凑的电子设备(如便携式仪器、小型通信模块)。

2. 安装与调节方式

  • 引脚类型:3个插件引脚(通常为“端接-滑动-端接”结构),直接焊接于PCB板,可靠性高;
  • 调节方式:顶部螺丝刀调节(十字/一字槽),属于“预设型”——仅需在设备调试阶段调整阻值,日常无需频繁手动操作,避免磨损导致阻值变化。

四、典型应用场景

结合参数特点,该电位器适用于以下场景:

1. 仪器仪表校准

  • 万用表、示波器、信号发生器等设备的基准电阻校准(如调整电阻档的测量精度);
  • 传感器信号调理电路(如压力传感器、温度传感器的输出信号校准)。

2. 电源电路调节

  • 开关电源的输出电压调节(通过改变反馈分压比,精准设置输出电压);
  • 线性电源的电流限制调节(避免过载损坏负载)。

3. 工业与通信设备

  • PLC输入输出模块的信号幅度校准;
  • 基站射频电路的偏置电压调节;
  • 光模块的光功率校准。

4. 消费电子领域

  • 高端音响的音调预设调节(如低音/高音平衡,仅需调试阶段设置);
  • 机顶盒的信号强度校准。

五、产品优势与注意事项

1. 核心优势

  • 品牌可靠性:BOURNS 作为全球知名电位器厂商,产品一致性好、寿命长(典型调节寿命≥1000次);
  • 精准调节:25圈多圈设计,满足精密预设需求;
  • 环保合规:型号后缀“LF”表示符合 RoHS 无铅标准,适配全球市场环保要求。

2. 注意事项

  • 功率限制:实际功耗不得超过500mW(若需更高功率,需选用同系列大功率型号);
  • 温度补偿:若应用环境温度波动大(如户外设备),需额外设计温度补偿电路;
  • 焊接规范:焊接温度不得超过260℃,焊接时间≤3秒,避免损坏内部有机绝缘材料;
  • 调节频率:仅为预设型,禁止频繁手动调节(否则会导致滑动触点磨损,阻值漂移)。

六、型号编码解析

BOURNS 3296Y-1-101LF 型号各部分含义:

  • 3296:系列标识(BOURNS 经典精密电位器系列);
  • Y:子系列(表示多圈、小型化封装);
  • 1:阻值系数(对应100Ω的编码逻辑);
  • 101:阻值编码(10×10¹=100Ω);
  • LF:无铅环保标识(RoHS 合规)。

综上,BOURNS 3296Y-1-101LF 凭借小型化、精准调节、稳定可靠的特点,成为工业级电子设备中“预设型电阻调节”的优选元件,适配多种需要精确电阻值设置的场景。

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.
