RK73H1JRTTD1002F厚膜固定电阻器产品概述

一、产品基本属性与核心参数

RK73H1JRTTD1002F是日本KOA公司推出的厚膜固定电阻器,属于其RK73系列经典型号,核心参数精准适配多数中小功率电路需求:

  • 阻值与精度:固定阻值10kΩ,精度等级±1%(型号中“J”标识对应该精度),可满足模拟电路中信号分压、偏置电压设置等对阻值精准度要求稳定的场景;
  • 功率规格:额定功率100mW(1/10W),适配低功耗电子设备的信号调理、控制电路;
  • 温度系数(TCR):±100ppm/℃,反映温度变化对阻值的影响——例如环境温度从25℃升至125℃时,阻值漂移约±1.25Ω,对多数电路功能无显著干扰;
  • 工作温度范围:-55℃至+155℃,覆盖工业级、部分汽车级应用的温度需求;
  • 封装形式:0603英制封装(对应公制1608,尺寸1.6mm×0.8mm),适合高密度PCB设计。

二、封装与工艺特点

该电阻采用0603表面贴装封装,结合厚膜工艺具备以下结构优势:

  1. 紧凑尺寸:1.6mm×0.8mm的小体积适配智能手机、可穿戴设备等对PCB空间要求严苛的产品,可实现高密度布局;
  2. 厚膜工艺:通过丝网印刷将电阻浆料涂覆在陶瓷基底上,经高温烧结而成——相比薄膜电阻成本更低,同时具备良好的长期稳定性与抗电涌能力;
  3. 焊端设计:采用适合回流焊的端电极结构,兼容无铅焊接工艺(符合RoHS环保要求),焊接后可靠性高,不易出现虚焊问题。

三、性能优势与应用适配性

RK73H1JRTTD1002F的参数组合使其在多场景下具备竞争力:

  • 精度与稳定性平衡:±1%精度无需额外校准,可直接用于多数消费电子、工业控制的信号电路;±100ppm/℃的TCR在宽温下阻值漂移可控,避免温度变化导致电路性能波动;
  • 功率与体积适配:100mW额定功率满足低功耗需求,无需冗余功率增加成本,小体积支持高密度设计;
  • 环保与可靠性:符合RoHS、REACH等环保标准,厚膜工艺使其耐湿、耐温冲击,可在潮湿或温度变化频繁场景下长期稳定工作。

四、可靠性与环境适应性

该电阻经KOA严格测试验证,可靠性满足多数工业与消费类应用:

  • 耐环境性能:工作温度-55℃~+155℃,可承受短时间温度冲击(如-40℃快速升至125℃);耐湿等级符合JIS C 5102标准,95%RH湿度环境下长期工作无衰减;
  • 长期稳定性:1000小时高温负载测试(125℃、额定功率)后,阻值变化率≤±0.5%,确保电路长期运行性能稳定;
  • 抗电涌能力:厚膜浆料特性使其可承受短时间过功率冲击(1.5倍额定功率下10秒内无损坏),适配复杂电路的瞬时电压波动。

五、典型应用领域

RK73H1JRTTD1002F因参数适配性强,广泛应用于以下领域:

  1. 消费电子:智能手机、平板电脑的电源管理分压反馈、音频信号调理电路;
  2. 工业控制:传感器接口(压力/温度传感器信号分压)、PLC输入输出接口;
  3. 通信设备:路由器、交换机的信号滤波、偏置电路;
  4. 汽车电子:车载信息娱乐系统的低功率辅助电路(如中控按键信号调理)。

综上,RK73H1JRTTD1002F是一款性价比高、性能稳定的厚膜电阻器,适配多数中小功率、宽温需求的电子电路设计,是KOA系列中应用广泛的经典型号。

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
