RK73H1JTTD1001F 厚膜固定电阻器产品概述

一、产品基本属性

RK73H1JTTD1001F是KOA株式会社推出的表面贴装厚膜固定电阻器,属于该品牌经典的RK73系列(小型化高可靠性厚膜电阻)。产品采用0603封装(英制尺寸代码,对应公制1608封装,即长1.6mm×宽0.8mm),适配回流焊、波峰焊等主流电子组装工艺,可兼容无铅焊接,符合RoHS环保标准。

二、核心性能参数

该电阻器的关键参数明确,满足中精度、小功率电路的常规需求:

  • 阻值与精度:标称阻值1kΩ(阻值代码“1001”,代表100×10¹=1000Ω),精度等级±1%,可满足信号分压、限流等应用对阻值一致性的要求;
  • 功率与电压:额定功率1/8W(125mW),最大连续工作电压75V,支持直流或交流(峰值)电路长期稳定工作;
  • 温度特性:温度系数(TCR)为±100ppm/℃,即环境温度每变化1℃,阻值变化±100ppm(1kΩ对应每℃变化±0.1Ω),适合温度波动较小的场景;
  • 工作温度范围:-55℃至+155℃,覆盖工业级(-40℃125℃)及部分汽车电子(-55℃150℃)的环境要求,适应恶劣工况。

三、封装与结构特点

  1. 尺寸与体积:0603封装典型物理尺寸为长1.6mm±0.15mm、宽0.8mm±0.15mm、厚0.45mm±0.10mm,体积小巧,可显著降低PCB板空间占用,适合便携设备、高密度模块设计;
  2. 工艺结构:采用厚膜丝网印刷工艺,在高纯度氧化铝陶瓷基底上印刷电阻浆料,经高温烧结形成电阻层,再通过镍/锡电极镀层实现焊接连接——相比碳膜电阻稳定性更高,相比薄膜电阻成本更具优势;
  3. 焊接可靠性:电极镀层采用抗硫化设计,可避免含硫环境(如工业场所、沿海地区)中的腐蚀,提升焊接点长期可靠性。

四、典型应用场景

RK73H1JTTD1001F的参数特性使其适用于多领域电子电路:

  • 消费电子:智能手机、智能穿戴设备的电源滤波、信号分压,音频接口阻抗匹配;
  • 工业控制:PLC传感器接口限流、小型电机驱动过流保护;
  • 汽车电子:车载仪表盘、音响系统信号处理(宽温适配车载温度波动);
  • 通信设备:路由器信号衰减网络、光模块辅助电路;
  • 医疗设备:小型监护仪、血糖仪的低功率信号调理(注重可靠性与小体积)。

五、可靠性与环境适应性

该产品具备良好的长期可靠性:

  • 温度稳定性:-55℃~+155℃范围内,2000小时老化后阻值漂移≤±0.5%;
  • 功率稳定性:1/8W额定功率下,1000小时负载寿命测试阻值变化≤±0.2%;
  • 抗环境性能:85℃/85%RH湿度测试1000小时后,阻值变化≤±0.5%;抗硫化符合JESD22-A101标准;
  • 寿命:典型工作寿命超过10000小时,满足工业设备长周期运行需求。

六、选型与替代参考

  • 精度升级:如需±0.1%高精度,可选KOA RK73H系列“F”精度版本(如RK73H1FTTD1001F);
  • 功率升级:如需1/4W(250mW),可选0805封装同系列产品(如RK73H2JTTD1001F);
  • 品牌替代:相同参数的替代型号包括Yageo RC0603FR-071KL、Murata ERJ-2RKF1001X等。

该产品以高性价比、宽温适应性和小体积优势,成为中低端电子电路设计的常用选型。

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
