4609X-101-103LF 产品概述

一、产品简介

4609X-101-103LF 是 BOURNS 提供的一款单列直插(SIP)电阻网络器件,器件包含 8 个电阻元件,标称阻值为 10 kΩ,精度为 ±2%。器件以 SIP-9(引脚间距 2.54 mm)封装提供,适合在密度要求适中且需多路阻值匹配的电路中替换离散电阻,简化装配并节省电路板空间。

二、主要特性

  • 电阻数量:8 个独立或网络配置(具体连线方式请依据厂商数据手册确认)
  • 阻值:10 kΩ(每个电阻)
  • 精度:±2%
  • 单个元件额定功率:200 mW
  • 温度系数(TCR):±100 ppm/℃
  • 封装:SIP-9,针脚数 9,引脚间距 2.54 mm
  • 品牌:BOURNS

这些特性使该器件在信号处理、阻抗匹配和基准网络等场景中具有良好的通用性,同时通过把多个电阻集成在一个封装内,可提升阻值配对一致性并减少装配工作量。

三、电气参数与注意事项

  • 标称阻值与公差:10 kΩ ±2%,适合对阻值精度有一定要求但不需要极高精度(如 0.1%)的应用。
  • 温漂:±100 ppm/℃,在环境温度变化时阻值变化可控,适合中低温度稳定性要求的应用;对高精度温度敏感电路需额外校准或选用更低 TCR 的器件。
  • 功率处理:单个电阻额定功率 200 mW,使用时需考虑功率分配与散热。若多个电阻同时承载较大功耗,建议评估 PCB 散热能力并进行必要的功率去率(derating)。
  • 网络配置:本型号描述为“RES ARRAY 8 RES 10K OHM”,但并未在此处明确是独立 8 只电阻还是带公共端的阻容网络,选型与电路设计时应参照 BOURNS 的数据手册确认引脚功能与内部连线。

四、机械与封装信息

  • 封装形式:SIP-9 直插式,适用于通孔插装。引脚间距 2.54 mm,便于与标准插座或面包板配合使用。
  • 封装优点:便于手工装配、维修和原型开发;比散装电阻节省 PCB 空间并提升阻值匹配一致性。
  • 安装提示:通过孔焊接时注意焊接温度与时间,避免对树脂或内部焊料造成损伤。

五、典型应用场景

  • 数模/模数转换器的拉取/偏置网络与输入匹配
  • 多路输入的分压或滤波前级(例如传感器阵列)
  • 电平移位、逻辑接口中的上拉/下拉阵列
  • 阻抗匹配和终端电阻网络(低频或中频应用)
  • 原型开发与实验室测试,便于快速布线与替换

六、设计与使用建议

  • 功率匹配与 PCB 设计:单个元件额定 200 mW,在高功耗场景下应留有合适的去率裕量。增加铜箔面积和良好通孔散热有助于提高可靠性。
  • 温度影响评估:TCR 为 ±100 ppm/℃,在温度跨度较大或对阻值变化敏感的应用中,需计算最大阻值偏差并决定是否采用温度补偿或更低 TCR 的元件。
  • 连线/功能确认:在设计电路板时务必确认该具体型号的内部连线(是否为独立电阻、是否有公共端、引脚排列)。错误的引脚理解可能导致电路功能异常。
  • EMC 与噪声:SIP 封装的近端电容和引线可能对高频性能有影响,若用于高频信号路径,需对寄生效应进行评估。

七、储存与焊接注意事项

  • 储存环境应避免极端温湿度与长时间日晒,维持在干燥、常温条件下以保证长期性能稳定。
  • 焊接时遵循通孔元件的温度曲线,避免超过封装能承受的最高温度。若需要波峰焊或回流工艺,务必参考 BOURNS 的焊接指南与最大温度限制。
  • 防静电措施:虽然一般电阻网络对静电敏感性较低,但在搬运和装配时仍建议采取基础防静电措施,保护其他敏感元件。

八、选型小结

4609X-101-103LF(BOURNS,SIP-9,8×10kΩ,±2%,200 mW,±100 ppm/℃)适用于需要多路阻值一致性、便于装配和维修的中低功耗应用。设计时应重点确认内部连线方式、考虑功率去率与温度漂移,并根据电路对精度与温度稳定性的要求决定是否为最佳选择。若需更高精度、更低温漂或不同网络拓扑,请参阅厂商完整产品系列与数据手册进行对比。

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.
