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。
该型号的关键参数直接决定应用适配性,具体如下:
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。
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)。
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。
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。
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。
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。
该型号因平衡精度、功耗与体积,广泛应用于:
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。
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。
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。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
