BOURNS 3296X-1-104LF 产品概述

BOURNS 3296X-1-104LF 是一款小型可调电阻(多圈精密电位器),面向电路微调与标定场合设计。该器件以紧凑的 SIP-3P 封装(尺寸约 10 × 4.8 mm)、25 圈调节机构和典型的精密特性,适合用于空间受限且需要反复精确调整的模拟电路、传感器标定和测试测量设备。

一、主要参数一览

  • 阻值:100 kΩ(标称值)
  • 精度(公差):±10%
  • 功率额定:500 mW(最大耗散功率)
  • 温度系数(TCR):±100 ppm/℃(典型)
  • 圈数:25 圈(多圈调节,便于精细调整)
  • 封装/外形:SIP-3P(3 引脚直插),标称外形 10 × 4.8 mm
  • 品牌:BOURNS
  • 系列/封装型号:3296X(3296X-1-104LF)

二、产品特性与优势

  • 精细可调:25 圈多圈结构使得在微小阻值变化范围内能够实现平滑、可控的调节,适合需要精确设定的电路参数。
  • 紧凑封装:SIP-3P 直插尺寸小,便于在 PCB 上节省空间并兼容自动化插装或手工焊接工艺。
  • 温度稳定性:±100 ppm/℃ 的温度系数在中等精度应用中能提供较好的阻值稳定性,适合工业、消费类电子的常温工作环境。
  • 适用范围广:适用于电阻分压、偏置调节、增益/截止频率微调、传感器零点/增益校准等多类电路。

三、典型应用场景

  • 模拟前端与放大器:用于调节增益、偏置点和直流平衡,便于在调试阶段或现场校准时精确设置。
  • 传感器与测量设备:对温度、压力、位移等传感器的零点与灵敏度进行微调,保证测量精度。
  • 电源与参考电路:作为可调分压器,用于获得精确的参考电压或细调低功耗电源参数(需注意功率额定)。
  • 工业控制与仪表:在控制器、数据采集模块中用于标定与现场调整。
  • 样机开发与实验台:因其可重复精细调节,适合工程验证与实验室使用。

四、典型电气与机械使用注意事项

  • 功率限制:500 mW 为器件最大连续耗散功率。实际使用时应考虑环境温度与散热条件,并按厂商建议进行功率降额使用以延长寿命。
  • 温度影响:±100 ppm/℃ 表明随温度变化阻值会发生变化。对于温度敏感的精密应用,建议在最终环境温度下完成校准或选用更低 TCR 的器件。
  • 调节与寿命:多圈调节提供了高分辨率,但频繁且大幅度的机械操作会影响接触面,建议按需调整并避免超出机械寿命范围。
  • 引脚连接:SIP-3P 通常三脚对应为两端电阻端点与中间滑动触点(电位器的滑动触点/线轴)。接线时应确认引脚排列并避免误接。
  • 焊接工艺:直插封装适合波峰或手工焊接。若采用波峰焊,需控制焊接温度与时间,避免对内部材料造成热应力。焊接后建议对阻值做简单检查与必要校准。
  • 清洁与环境:避免使用侵蚀性溶剂清洗滑动端或密封部位。若应用于潮湿或腐蚀性环境,应考虑额外防护或选择具备更高环境密封等级的替代型号。

五、选型与采购建议

  • 若应用对精度或温漂有更高要求,可考虑更低公差(如 ±5% 或 ±1%)或更低 TCR 的型号;对于高功率场合,应选择功率额定更高的电位器或改用分立电阻网络。
  • 识别型号:3296X-1-104LF 中的 “104” 通常代表 100kΩ 阻值,选型时确认阻值、圈数与封装是否满足 PCB 布局与安装要求。
  • 备件与替代:在量产或长期维护中建议同时备有若干原厂或同规格替代件,以避免单一供应导致停产风险。

六、总结

BOURNS 3296X-1-104LF 是一款面向精细调节与空间受限电路的多圈可调电阻,结合 25 圈细调机构、100 kΩ 阻值与紧凑的 SIP-3P 封装,适合用于模拟调校、传感器标定与试验平台等场景。选用时需注意功率限值与温漂影响,并在最终应用环境下进行必要的校准与验证,以确保长期稳定运行。

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
