3296Y-1-104LF 产品概述

一、概述与主要参数

3296Y-1-104LF 为 BOURNS 出品的多圈可调电阻(电位器)微调器,属于紧凑型插件(through‑hole)可调电阻器。核心参数如下:

  • 阻值:100 kΩ(104)
  • 精度(初始公差):±10%
  • 功率:0.5 W(500 mW)
  • 圈数:25 圈(多圈,便于细调)
  • 封装:插件-3P(三端),外形尺寸约 9.5 × 4.8 mm 该型号适用于需要较高调节精度与稳定性的电路微调与校准场合。

二、产品特点

  • 多圈设计(25圈):相较于单圈电位器,多圈结构提供更细腻的调节步进和更高的分辨率,便于在增益、偏置和滤波参数上实现精确设定。
  • 小体积插件封装:9.5×4.8 mm 紧凑外形适配空间受限的 PCB 布局,三端插件便于手工或波峰/选择性焊接安装。
  • 适合精密调校:配合 25 圈结构与 0.5W 功率等级,适合对功耗要求不高但需高稳定性的校准场合,如测量仪表、传感器校准与放大器偏置调整。
  • 品牌与可靠性:BOURNS 为行业知名元器件厂商,产品一致性与长期可得性良好,便于批量生产与维护更换。

三、典型应用场景

  • 模拟前端校准:传感器零点/量程微调、差分放大器偏置校正
  • 精密滤波器与积分/微分电路的定点调节
  • 电源与基准电压微调(注意功率限制,不宜长期承载接近额定功耗)
  • 音频设备的微调电路与参数设定(低功耗控制)
  • 实验台与开发板的可调电阻模块,用于参数验证与快速迭代

四、安装与使用注意事项

  • 功率与散热:额定功率为 500 mW,实际应用中建议留有裕度(尽量在额定功率的 50%~70% 以下长期使用),避免因过高功耗造成寿命降低或漂移。
  • 调节方式:多圈设计调节量小、步进细,建议使用合适尺寸的调节螺丝刀并避免过大力矩以防损伤驱动机构。
  • 焊接建议:插件封装可用手工或机械焊接,焊接时避免长时间高温作用于塑料件与电阻体,推荐快速焊接、适当预热与间隔冷却。
  • 电气连接:接线或焊接后应检查接触电阻与回路完整性,避免松焊或虚焊造成调节漂移。
  • 环境与机械应力:避免在振动剧烈或潮湿腐蚀环境中使用,必要时配合封装或密封处理;安装时勿施加过大机械应力于引脚和本体。

五、替代与选型建议

  • 若需更高功率承载或不同阻值/精度,可参阅 BOURNS 其他 3296 系列或同类多圈微调电位器(注意匹配圈数、阻值、功率与封装)。
  • 对要求更高长期稳定性和温漂的场合,可考虑更高精度(±5% 或更好)及不同电阻膜材(如薄膜金属化)型号。
  • 在空间或焊接工艺受限时,也可考量 SMD 多圈电位器的方案,但需评估可调行程与操作便利性。

六、存储与可靠性建议

  • 存放环境应保持干燥、避免阳光直射与强酸碱气氛,推荐温度范围与湿度条件遵循常规电子元件储存规范。
  • 长期库存前如包装开启后,应避免接触尘埃与潮气,必要时回潮烘烤后再使用。
  • 在产品选型与设计中,提前预留替换空间与维护方案,可减少后期维护成本。

总结:3296Y-1-104LF 是一款适合精细调节与校准的 25 圈 100 kΩ 插件微调电位器,功率 0.5W、体积小巧,适用于各类需要精密调节的模拟电路与开发验证场景。在实际使用中注意功率裕度、焊接工艺与机械保护,可获得稳定可靠的长期表现。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

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
