BOURNS 3224X-1-202E 产品概述

一、产品简介

3224X-1-202E 为 BOURNS 的多圈微调电位器(trimmer),标称阻值 2 kΩ,阻值公差 ±10%,额定功率 0.25 W,温度系数 ±100 ppm/℃,圈数 12 圈,顶端旋钮调节(top adjust)。该器件适用于需要精确微调阻值以完成偏置、增益、校准等电路参数设定的场合。

二、主要电气规格

  • 阻值:2 kΩ(±10%)
  • 额定功率:0.25 W(连续工作时的最大耗散能力,请参照厂商曲线进行热功率限制)
  • 温度系数:±100 ppm/℃(反映随温度变化的阻值漂移)
  • 触点结构与最大工作电压/电流:请以原厂数据表为准(本条目未提供具体值)

三、机械与调节特性

  • 圈数:12 圈,多圈设计提供较高的可调解析度与重复定位精度,适合精细调节任务
  • 调节方式:顶部调节(top adjust),便于安装后通过工具直接访问调整件,无需拆卸 PCB
  • 封装:用户未提供具体封装型号,建议在采购前确认机械尺寸、安装孔位与引脚排布,确保与设计板兼容

四、应用场景

  • 模拟电路微调:放大器偏置、滤波器中心频率、增益调节
  • 传感器校准:零点/满量程微调、灵敏度匹配
  • 功率受限或空间受限的精密设备:由于额定功率为 0.25 W,更适合信号级而非大功率路径
  • 测试与维护:作为调试、生产校准用可调元件

五、选型与使用建议

  • 若电路存在较高功率或长期高温工况,应选用更高功率等级或在电路设计上进行功率分担和散热设计
  • 对阻值稳定性有更高要求时,考虑更低温漂(ppm/℃)和更窄公差的型号
  • 多圈设计虽然提高精度,但调整次数和速度较单圈慢,设计时权衡调节便捷性与精细度
  • 确认安装方向与调节工具尺寸(通常为小一字或六角),避免因工具不匹配损伤调节头

六、可靠性与存储

  • 遵循厂家推荐的焊接工艺与温度曲线,避免在高温下长时间暴露
  • 储存时避免潮湿和极端温度,出厂后在长期存储前建议密封保存以防氧化
  • 在有振动或冲击的应用中,应评估机械固定和锁定措施,防止调节机构松动

七、采购与替代方案

  • 采购前确认完整料号、封装尺寸与引脚定义,并参考原厂数据表及样品测试
  • 若需要更高精度或不同功率、不同调整方式,可在 BOURNS 或其他厂商的多圈微调系列中选型替代

注意:以上为基于提供基础参数的产品概述。最终设计与可靠性评估应以 BOURNS 官方数据手册与样品测试结果为准。

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
