二、关键参数详解

RK73H1ETTP2004F的核心参数围绕阻值、精度、功率等核心性能展开,具体如下:

  • 阻值与精度:标称阻值2MΩ(阻值编码“2004”表示200×10⁴Ω),精度±1%,可覆盖大多数电路对电阻值的精准控制需求;
  • 功率与电压:额定功率100mW,最大工作电压75V(实际使用需遵循“电压≤75V且功率≤100mW”的限制,避免过压/过功率损坏);
  • 温度系数(TC):±200ppm/℃,即温度每变化1℃,阻值变化约±0.4Ω,属于厚膜电阻的常规稳定水平,满足多数应用的温漂要求;
  • 工作温度范围:-55℃至+155℃,覆盖工业级、汽车级的温度需求,可在高温(如发动机舱)、低温(如户外设备)环境下稳定工作。

三、封装与物理特性

该电阻采用0402封装(英制尺寸,对应公制1005),具体物理参数如下(基于常规0402封装标准):

  • 封装尺寸:长度1.0±0.1mm,宽度0.5±0.1mm,高度0.35±0.05mm;
  • 焊盘适配:兼容标准0402贴片焊盘,可通过回流焊、波峰焊等常规工艺焊接;
  • 工艺特点:采用丝网印刷厚膜电阻浆料于陶瓷基底,经高温烧结而成,具备良好的附着力与抗老化性。

四、环境适应性

RK73H1ETTP2004F的环境适应性覆盖多维度,满足复杂场景需求:

  • 温度耐受性:-55℃至+155℃宽温范围,符合汽车电子、工业控制的极端温度要求;
  • 湿度稳定性:厚膜工艺对湿度不敏感,可承受相对湿度95%以上的环境(符合IEC 60068-2-67标准);
  • 振动与冲击:贴片封装结构牢固,可承受10Hz~2000Hz振动(加速度2g)、100g/1ms冲击,满足工业设备的可靠性要求。

五、典型应用场景

基于高阻、小封装、宽温的特性,RK73H1ETTP2004F广泛应用于以下场景:

  1. 信号调理电路:传感器接口的偏置电阻、运算放大器的反馈电阻,利用高阻值实现微弱信号放大;
  2. 电源分压网络:DC-DC转换器的电压反馈回路,通过2MΩ高阻实现精准分压;
  3. 小型化电子设备:可穿戴设备、便携电子产品的电路设计,适配高密度PCB布局;
  4. 工业控制模块:PLC、变频器的辅助电路,宽温特性满足工业现场的温度波动;

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
