二、核心电气性能参数

该电阻的关键指标清晰可控,满足大多数通用电路的精度与功率要求:

  1. 阻值与精度:标称阻值30.1Ω,精度等级±1%,室温下阻值偏差≤0.301Ω,适合分压、信号调理等对一致性有基本要求的场景;
  2. 功率与电压:额定功率125mW(1/8W),额定功率下最大工作电压约1.94V(计算:(V=\sqrt{P×R}=\sqrt{0.125×30.1})),可稳定承载小功率负载;
  3. 温度系数(TCR):阻值温度系数±100ppm/℃,即温度每变化1℃,阻值变化≤0.01%,宽温区下阻值稳定性良好;
  4. 工作温度范围:适用-55℃~+155℃,覆盖工业级与部分汽车级应用的温区要求,极端环境下仍能稳定工作。

三、封装与机械特性

采用0603封装(公制对应1608规格),具体尺寸为1.6mm(长)×0.8mm(宽)×0.45mm(高),是高密度PCB设计的常用小封装。端接采用无铅锡镀层,符合RoHS环保指令,兼容回流焊、波峰焊等标准SMD工艺;焊接后机械强度可靠,引脚间距与PCB焊盘适配性好,便于自动化贴装,提升组装效率。

四、典型应用场景

基于小封装、宽温区与通用性能,该电阻适用于以下场景:

  1. 消费电子:智能手机、平板、智能穿戴的电源管理(分压检测、电流采样)、信号调理(滤波、匹配);
  2. 工业控制:小型PLC、传感器接口(温度/压力传感器信号放大)、微控制器周边(上拉/下拉电阻);
  3. 汽车电子:车载小功率控制单元(仪表盘背光、车门控制),宽温区适配舱内/舱外温度变化;
  4. 医疗设备:便携式医疗仪器(血糖监测仪、小型监护仪)的电路模块,满足小型化与可靠性要求;
  5. 通信终端:路由器、无线AP的射频周边(信号衰减、阻抗匹配),适配高密度设计。

五、可靠性与环境适应性

KOA对该系列电阻进行了严格可靠性验证,主要表现为:

  1. 温湿度耐受:-55℃~+155℃温度循环无失效,85℃/85%RH湿度环境下阻值变化≤0.5%;
  2. 焊接可靠性:回流焊峰值260℃(持续10秒)无开裂、端接脱落;
  3. 长期稳定性:125℃下施加额定功率1000小时,阻值变化≤1%;
  4. 机械应力:符合IEC 60068-2-6振动测试标准,可承受运输与使用中的机械冲击。

六、品牌与系列优势

作为KOA旗下通用厚膜电阻,该型号具备明显优势:

  1. 品牌品质:KOA数十年电阻制造经验,产品一致性好,故障率低;
  2. 成本效益:厚膜工艺成熟,性能与成本平衡,适合大规模量产;
  3. 供货稳定:全球供应链完善,常规型号供货周期短;
  4. 参数覆盖广:RK73H系列阻值范围宽(几Ω~几MΩ),精度、功率可选,便于电路选型。

该电阻是小型化电子设备中通用电路的高性价比选择,可满足多数常规应用的性能与可靠性需求。

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
