3362P-1-500LF 产品概述

一、产品概述

3362P-1-500LF 是 BOURNS 出品的一款单圈可调电阻(微调电位器),采用通孔三脚封装,外形紧凑(7 × 6.6 mm),适用于电路板上做精细电阻值调整与校准。该型号阻值为 50 Ω,额定功率 500 mW,阻值精度 ±10%,温度系数 ±100 ppm/℃,圈数为 1 圈,适合占板空间受限且需稳定微调的场合。

二、主要参数

  • 阻值:50 Ω
  • 精度(标称容差):±10%
  • 额定功率:500 mW(在额定环境下)
  • 温度系数:±100 ppm/℃(温漂较低,适合对温度稳定性有要求的应用)
  • 圈数:1(单圈,一级旋转范围完成全部阻值变化)
  • 封装:通孔(插件)三脚,外形尺寸约 7 × 6.6 mm
  • 品牌:BOURNS(3362P 系列中的延伸型号)

三、结构与封装特点

3362P-1-500LF 属于小型单圈微调电位器,典型为陶瓷/金属氧化物(cermet)阻体,三脚结构便于形成分压器或作为可变电阻置入电路。通孔引脚便于波峰或手工焊接,紧凑尺寸有利于高密度组装与自动化贴装后的焊接流程。

四、性能亮点

  • 温度稳定性:±100 ppm/℃ 的温漂在小功率微调元件中表现良好,适合要求一定温度恒定性的校准场合。
  • 精密调节:单圈设计便于快速完成全行程调整,适合生产调校或维修时快速定位。
  • 小尺寸高适配性:7×6.6 mm 的占板面积适合便携设备和密集电路板布局。
  • 稳定性与重复性:BOURNS 品牌与 3362P 系列的工艺保证了调节重复性的可靠性,适合长期运行后的微调保持。

五、典型应用场景

  • 放大器增益与偏置的现场微调与校准
  • 传感器零点与灵敏度调整(如温度、压力传感器的标定)
  • 仪表、测试设备的零点和刻度校准
  • 通讯与音频电路的微调匹配
  • 消费电子中占板空间受限的分压或可变电阻需求

六、选型与使用建议

  • 如果电路中耗散功率接近或超过 500 mW,应考虑使用功率更高的多圈电位器或外接限流/散热措施;长时间高功率运行会导致发热与寿命下降。
  • 单圈设计便于快速调整,但调整精度不如多圈微调器,如需细致微调或重复定位精度更高,建议选用多圈型号。
  • 焊接时避免长时间高温直接作用在元件引脚上,遵循厂家推荐的焊接曲线以免影响阻值与温漂。
  • 调节工具建议使用合适尺寸的一字/十字螺丝刀或专用调节批,避免用力过猛导致轴心损伤或超出行程。

七、可靠性与资料查询

有关环境温度范围、机械寿命、耐振动/冲击指标及合规性(如 RoHS)等更详细的规格与测试数据,请参阅 BOURNS 官方数据手册或联系供应商索取技术资料。选型与批量应用前,建议在目标系统中进行样件验证与长期可靠性试验。

总结:3362P-1-500LF 以其小体积、良好温漂和便捷的通孔安装特点,适合板上微调及校准用途。在选型时根据功率、精度与调整需求权衡是否采用本型号或选择更高精度/更高功率的替代品。

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
