3314G-1-104E 产品概述(Bourns 可调电阻 / 电位器)

一、产品简介

3314G-1-104E 是 Bourns 提供的一款表面贴装单圈可调电阻(trimmer potentiometer),典型应用于精密调校、偏置/增益调节与电路校准。该型号阻值为 100 kΩ,额定功率 250 mW,温度系数 ±100 ppm/℃,标称精度 ±20%,单圈调节,封装为 SMD-3P,外形尺寸约 4.5 × 4.5 mm。体积小、易于 SMT 装配,适合空间受限的便携式与嵌入式电子设备。

二、关键参数一览

  • 阻值:100 kΩ(100kΩ)
  • 精度(初始阻值公差):±20%
  • 功率额定值:250 mW(环境/温度相关,具体请参照厂商数据手册)
  • 温度系数:±100 ppm/℃(表征随温度变化的阻值漂移)
  • 圈数:1(单圈调节)
  • 封装/尺寸:SMD-3P,约 4.5 × 4.5 mm
  • 品牌:BOURNS(生产与质量支持)

三、产品特性与优势

  • 小型化封装:4.5×4.5 mm SMD 封装适合 PCB 密集布局,便于自动化贴装与回流焊工艺。
  • 良好的温度稳定性:±100 ppm/℃ 的温度系数,在多数工业与消费电子温度范围内能够保持阻值稳定性,利于长期校准精度。
  • 低功耗应用适配:250 mW 的功率额定值适合信号级调整与低功耗电路的微调需求。
  • 调节方便:单圈设计使得设置和校准操作直观快捷,适用于设备出厂校准或现场微调。
  • 品牌可靠:Bourns 在精密可调电阻领域经验丰富,质量与可追溯性有保障。

四、典型应用场景

  • 模拟信号调节:偏置电压、增益设定、电平校准等。
  • 传感器与测量电路:传感器零点/灵敏度微调、标定电路。
  • 通信设备:增益和偏置微调、电路匹配。
  • 工业与仪器设备:出厂校准、现场维护调整。
  • 消费电子与便携设备:体积受限场合下的电路微调方案。

五、设计与使用建议

  • 封装与焊接:3314G-1-104E 为 SMD 型产品,可采用常规回流焊装配。为保证可靠性与性能,应按 Bourns 推荐的回流曲线与 PCB 布局指南设计焊盘与热量分布,避免局部过热。
  • 电路配置:作为可调分压元件使用时,注意电压与功耗不要超过额定值,必要时可通过串联电阻或更高功率元件分担功耗。
  • 调整操作:使用与厂商推荐相配套的调整工具(例如低应力旋具)进行设置,避免对调整端施加过大轴向或侧向力,防止损伤结构或改变设定值。
  • 环境与热管理:虽然温度系数表现良好,但在高温或温度波动大的环境中,应验证漂移对电路性能的影响;必要时采取温度补偿或选用温漂更优的元件。

六、存储与维护注意事项

  • 存储环境:避免潮湿、酸性或过度尘埃环境,长时间存储应按元器件通用规格(干燥、阴凉)保存。
  • 防静电与防机械冲击:尽管为无源元件,搬运时仍应避免强烈机械冲击与不当操作导致结构损伤。
  • 定期校验:在关键应用中,建议在设备维护周期内进行校准检查,保证电路调校值稳定。

七、选型与采购建议

  • 阻值与精度:本型号为 100 kΩ、±20% 的通用调节件,若需求更高初始精度或更低温漂,可考虑 Bourns 同系列或其他系列的高精度型号。
  • 功率与环境:若电路功耗或工作温度超出本件额定能力,请按系统要求选择更高功率或更高温漂等级的器件。
  • 认证与质量:采购时可向供应商确认产品批次、原厂合格证及可追溯性资料,以满足量产与质量控制要求。

结语:3314G-1-104E 以其紧凑的 SMD 封装、适中的功率额定与良好的温度稳定性,适合多种需要现场或出厂微调的小功率应用。具体电气与机械参数、回流焊工艺和耐久性等详细信息,请参照 Bourns 官方数据手册或联系授权代理获取完整规格说明。

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
