BOURNS 3296W-1-253LF 精密可调电位器产品概述

一、产品定位与核心身份

BOURNS 3296W-1-253LF是一款工业级精密微调电位器,属于BOURNS经典3296W系列成员。该产品针对需要稳定阻值调整、精细分辨率的电路场景设计,兼顾低功耗、紧凑体积与可靠性能,是工业控制、通信设备、测试仪器等领域的常用选型之一。

二、核心电气参数详解

该型号的关键参数直接决定应用适配性,具体如下:

1. 阻值与精度

  • 标称阻值:25kΩ(标识代码“253”,即25×10³Ω);
  • 阻值精度:±10%,满足多数工业电路对阻值误差的基础要求,无需额外校准即可适配一般信号调理场景。

2. 功率与温度特性

  • 额定功率:500mW(0.5W),属于低功耗电位器,适配电源电压≤112V(按P=U²/R计算)的电路;
  • 温度系数:±100ppm/℃,表示环境温度每变化1℃,阻值变化约0.01%,优于普通电位器(通常±200ppm/℃),可有效降低温度波动对电路性能的影响。

3. 调整分辨率

  • 调整圈数:25圈,属于多圈微调设计。相比单圈电位器(仅360°调整),25圈可将阻值变化细化,实现更精确设置(如25kΩ阻值下,每圈调整约1kΩ,适合精细校准场景)。

三、结构设计与封装特性

1. 封装形式

采用SIP-3P(单列直插3引脚) 封装,引脚布局符合标准通孔焊接规范,可直接焊接于PCB板,安装便捷且可靠性高。

2. 尺寸规格

体积为9.5mm×4.8mm,属于紧凑型设计,可有效节省PCB空间,适配小型化设备(如手持测试仪器、微型通信模块)。

3. 调整方式

通常采用顶部十字槽调整(需配合小型螺丝刀操作),调整过程中阻值变化平滑,无明显跳变,适合需要多次微调的场景。

四、性能可靠性与环境适应性

1. 阻值稳定性

多圈设计减少单次调整的阻值波动,结合低温度系数,长期使用(或温度变化)下阻值漂移小,可保持电路参数一致性。

2. 电气寿命

BOURNS 3296W系列电位器典型电气寿命为1000次以上调整循环,即使频繁校准也能维持性能稳定,适合需要反复调整的工业设备。

3. 环境耐受范围

参考同系列产品规格,该型号可适应**-55℃~+125℃** 工作温度范围,满足工业级环境(如户外设备、高温车间)的使用要求。

五、典型应用场景

该型号因平衡精度、功耗与体积,广泛应用于:

  1. 工业控制:PLC输入/输出模块校准、变频器参数设置、传感器信号调理(如压力/温度传感器零点校准);
  2. 通信设备:基站射频电路信号衰减调整、路由器频率校准、光纤收发器信号增益微调;
  3. 测试仪器:示波器量程校准、信号发生器输出幅值调整、万用表基准电压校准;
  4. 消费电子:高端音频设备音量/音调微调(低功耗不影响音质)、电源模块输出电压调整(如DC-DC转换器反馈电阻设置)。

六、品牌与选型价值

1. BOURNS品牌优势

BOURNS是全球知名电子元器件制造商,专注精密电位器、电感等领域,产品以高一致性、可靠性能著称,广泛应用于汽车、工业、通信等高端领域。

2. 选型适配性

3296W系列覆盖100Ω~1MΩ以上阻值范围,25kΩ属于常用阻值,市场供应充足,替换时无需更改PCB布局,适配性强。

3. 性价比

作为工业级精密电位器,该型号在性能(温度系数、分辨率)与成本间实现平衡,适合中高端应用的预算需求,避免高端电位器的过高成本。

以上内容覆盖该型号核心特性与应用,可作为选型参考或产品技术文档基础部分。

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
