3362W-1-503LF 产品概述

一、产品简介

3362W-1-503LF 为 BOURNS 出品的一款单圈可调电阻(电位器),标称阻值 50kΩ(代码 503),额定功率 500mW,公差 ±10%,温度系数 ±100ppm/℃,圈数 1,封装为插件式 3P(7×6.6mm)。LF 后缀通常指无铅/符合 RoHS 要求的版本,适合精密调节与电路调试场合。

二、主要电气参数

  • 阻值:50kΩ(标称)
  • 精度:±10%(默认出厂)
  • 额定功率:500mW(在规定环境温度下)
  • 温度系数:±100ppm/℃(保证在温度变化时阻值稳定性)
  • 接脚:3P,通过孔插件,便于手工或波峰焊安装

三、结构与封装

该器件为单圈调节结构,体积小巧(约 7×6.6mm),顶端或侧面可用旋具进行调整。插件封装便于在通孔 PCB 上牢固安装,适合批量生产及维修更换。LF 型号适配无铅工艺,注意焊接温度和时间控制以防损伤。

四、典型应用场景

  • 模拟电路的偏置/增益微调与校准
  • 传感器零点与量程调整
  • 信号调理与滤波器的微调
  • 工业与消费类电子的调试与维修场合
    因为为单圈、功率与精度级别限制,更适合用于电路内部调校,而非作为频繁操作的面板旋钮。

五、使用与选型建议

  • 功率使用须留裕量:尽量在额定功率以下稳态工作,考虑环境温度及散热条件;长时间接近额定功率会影响可靠性。
  • 温度影响:±100ppm/℃ 表明温度变化对阻值影响较小,但在高精度应用仍需考虑温漂补偿。
  • 安装与焊接:遵循无铅焊接温度曲线,避免长时间高温暴露,手工焊接建议控制在短时间内完成。
  • 寿命与可靠性:作为调试型可调电阻,适合少量调整场合;若需频繁调节或面板操作,考虑采用多圈或滑动型电位器。

六、注意事项与维护

  • 存放干燥防潮,避免机械冲击与强腐蚀性气体环境。
  • 调节时避免过大扭矩或使用不合适工具,防止损坏调节机构。
  • 若用于精密测量回路,调节完成后建议固定位置或进行电路封装以防漂移。

七、总结

3362W-1-503LF 提供了小型化、可靠的单圈可调阻解决方案,凭借 50kΩ 阻值、500mW 功率和 ±100ppm/℃ 的温漂特性,适合电路调试与精度要求中等的校准场景。选型时应综合考虑功率裕量、使用频率与环境条件,以确保长期稳定工作。若需进一步电气图纸、封装尺寸或订购信息,可参考 BOURNS 官方数据手册或向供应商咨询具体规格表。

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
