RK73H1JTTD4701F 厚膜固定电阻器产品概述

RK73H1JTTD4701F是KOA品牌推出的一款小型化表面贴装厚膜固定电阻器,针对高精度、小功率电子电路设计,兼顾性能稳定性与成本经济性,广泛适配消费类、工业级及汽车电子等多领域应用场景。

一、产品基本定位

该型号属于KOA常规厚膜电阻系列,采用成熟的厚膜工艺制造,以0603(公制1608)小型化封装为核心设计,主要满足对阻值精度要求较高、电路空间受限的电子设备需求。其核心参数围绕“高精度、宽温稳定、小功率适配”展开,是电子电路中分压、滤波、信号匹配等基础功能的理想选择。

二、核心性能参数详解

1. 阻值与精度

标称阻值为4.7kΩ(4700Ω),精度等级为±1%,属于工业级常用高精度规格。该精度可有效避免因电阻偏差导致的信号偏移、功率损耗异常等问题,适用于对输出精度要求严格的电路(如传感器信号调理、模拟电路滤波)。

2. 功率与电压额定值

  • 额定功率:100mW(1/10W),可支撑低至中等功率的电路工作(如小电流信号电路、LED驱动辅助电阻);
  • 最大工作电压:75V,在额定功率范围内可承受的最高电压,避免过压击穿风险,适配多数低压直流/交流电路。

3. 温度特性

  • 温度系数(TCR):±100ppm/℃,表示温度每变化1℃,阻值变化约0.01%,在宽温度范围内保持阻值稳定性;
  • 工作温度范围:-55℃至+155℃,覆盖工业级低温(如户外设备冬季工况)与高温(如车载电子夏季工况)环境,满足极端温度下的可靠性需求。

三、封装与物理特性

该电阻采用0603表面贴装封装(对应公制1608尺寸:长1.6mm×宽0.8mm×厚0.4mm左右),具备以下优势:

  1. 高密度布局适配:小型化尺寸适合智能手机、智能穿戴、小型通信模块等高密度PCB设计;
  2. 自动化生产兼容:支持SMT贴装工艺,可与其他0603封装元器件同步贴装,提升量产效率;
  3. 厚膜工艺优势:相比薄膜电阻,厚膜工艺成本更低,且抗机械应力、抗潮湿能力更强,长期使用阻值漂移小。

四、典型应用场景

结合参数特性,RK73H1JTTD4701F主要应用于以下领域:

  1. 消费类电子:手机、平板电脑、智能手表的信号调理电路(如滤波电容匹配、传感器分压);
  2. 工业控制:PLC模块、小型传感器接口电路、电机驱动辅助电阻;
  3. 汽车电子:车载信息娱乐系统(如中控屏信号处理)、胎压监测模块的低功率电路(适配宽温环境);
  4. 通信设备:小型基站、路由器、WiFi模块的电源分压、信号匹配电路。

五、可靠性与品质保障

KOA作为全球知名电子元器件制造商,对该型号产品进行了严格的可靠性测试,确保:

  • 阻值一致性:批量产品阻值偏差控制在±1%范围内,满足量产项目的一致性要求;
  • 环境耐受性:通过高低温循环、湿度老化等测试,长期使用性能稳定;
  • 环保合规:符合RoHS、REACH等国际环保标准,不含铅、镉等有害物质;
  • 认证齐全:可提供完整的质量认证文件(如SGS报告、产品规格书),支撑客户的项目认证需求。

该型号凭借稳定的性能、小型化封装及成本优势,成为电子电路设计中基础电阻的高性价比选择,可满足多数常规电子设备的应用需求。

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
