RK73H1JTTD4022F厚膜固定电阻器产品概述

RK73H1JTTD4022F是日本KOA公司推出的0603封装通用厚膜电阻,针对小型化、高密度电路设计优化,兼具高精度、宽温适应性与稳定性能,适用于消费电子、工业控制等多领域。以下从核心特性、参数、应用等维度详细说明:

一、产品定位与核心特性

该电阻定位于小功率厚膜电阻,核心优势围绕“小封装+高精度+宽温可靠”展开:

  • 采用厚膜工艺,平衡成本与性能稳定性;
  • 0603(1608公制)超小封装,适配高密度PCB布局;
  • ±1%阻值精度,满足多数电路对阻值一致性的要求;
  • 宽温范围(-55℃~+155℃),适应极端环境场景。

二、基础电气参数详解

1. 阻值与精度

标准阻值为40.2kΩ,精度±1%(E96系列),实际阻值范围39.798kΩ~40.602kΩ,可满足模拟电路、信号调节等对偏差敏感的应用。

2. 功率额定值

额定功率100mW(1/10W),是0603封装厚膜电阻的典型规格。结合阻值计算,最大持续电流约1.57mA(I=√(P/R)=√(0.1W/40200Ω)),适配小电流电路。

3. 工作电压与温度系数

  • 最大工作电压:75V(直流/交流峰值),需严格控制电路电压不超限;
  • 温度系数(TC):±100ppm/℃,即温度每变化1℃,阻值漂移±0.01%。若温差130℃(如25℃→155℃),阻值最大漂移±1.3%,满足工业、汽车电子的温漂要求。

三、封装与物理特性

1. 封装规格

采用0603英寸(1608公制) 表面贴装封装,尺寸1.6mm×0.8mm×0.4mm,是小型化电路的主流选择,可显著降低PCB占用面积,适配智能手机、可穿戴设备等紧凑设计。

2. 厚膜工艺优势

厚膜电阻通过丝网印刷、烧结制备,相比薄膜电阻成本更低,相比碳膜电阻稳定性更好;厚膜层附着力强,长期使用阻值漂移小。

四、环境适应性表现

1. 宽温工作能力

覆盖**-55℃~+155℃**,可适应:

  • 汽车电子:低温启动(-40℃以下)与高温运行(发动机舱125℃以上);
  • 工业控制:车间高温(焊接工位)或低温户外场景;
  • 消费电子:户外暴晒等极端使用温度。

2. 可靠性验证

KOA对该系列进行高温存储、温度循环等测试,确保极端环境下阻值变化率≤1%(典型值),满足工业级寿命要求。

五、典型应用场景

结合参数特性,核心应用包括:

  1. 消费电子:智能手机传感器信号调节、蓝牙耳机电源分压、智能手环LED驱动限流;
  2. 工业控制:小型PLC模拟量输入接口、传感器信号放大反馈电阻;
  3. 汽车电子:车载中控按键电路、倒车雷达信号处理(适配汽车级温区);
  4. 通信设备:小型路由器电源滤波、无线模块信号匹配。

六、选型与使用注意事项

1. 功率降额

实际功率建议不超过额定值的70%(≤70mW),避免长期过载导致失效;脉冲电路需额外计算峰值功率。

2. 电压限制

直流电压≤75V,交流电路需注意峰值(如220V交流峰值311V,禁止使用)。

3. 焊接工艺

适配回流焊(峰值≤260℃,持续≤10秒)、手工焊(≤350℃,持续≤3秒),避免高温损坏。

4. 存储搬运

存储于25℃±10℃、湿度≤60%的干燥环境,搬运时防机械冲击与静电。

总结:RK73H1JTTD4022F是高性价比的0603厚膜电阻,以小体积、高精度、宽温可靠为核心优势,可广泛替代同类进口电阻,满足多领域小型化电路需求。

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
