RK73H1JTTD6802F厚膜电阻器产品概述

一、品牌与封装规格

RK73H1JTTD6802F由日本知名电子元器件厂商KOA生产,KOA在电阻器领域拥有数十年技术积累,产品以一致性高、稳定性强著称。该电阻采用0603封装(英制命名,对应公制尺寸1608),典型封装尺寸为1.6mm×0.8mm×0.45mm,属于小型表面贴装封装,适配高密度PCB设计,可通过回流焊、波峰焊等主流贴装工艺实现自动化生产,适合对空间要求严格的小型化设备。

二、核心电气性能参数

该电阻为厚膜电阻,核心电气参数明确且适配多数通用场景:

  • 标称阻值:68kΩ,精度等级为**±1%**,可满足工业控制、消费电子等场景对阻值一致性的基本要求;
  • 额定功率:100mW(即1/10W),在额定功率范围内可长期稳定工作,低功耗特性适配电池供电或低功耗电路;
  • 额定工作电压:75V(直流/交流兼容),在额定电压下不会出现击穿或性能衰减;
  • 温度系数(TCR):±100ppm/℃,表示温度每变化1℃,阻值变化率为±0.01%(以68kΩ为例,温度变化100℃时,阻值变化约±680Ω),宽温环境下阻值漂移可控;
  • 工作温度范围:-55℃~+155℃,覆盖工业级与汽车级常用温度区间,可适应极端环境下的稳定工作。

三、关键性能特点

  1. 厚膜工艺优势:采用丝网印刷+烧结工艺制造,相比碳膜电阻具有更好的长期稳定性(阻值漂移小),抗浪涌能力优于薄膜电阻,适合存在短暂脉冲的电路场景;
  2. 高精度与小封装平衡:±1%精度可替代部分需要较高阻值一致性的电路(如分压网络),0603封装大幅节省PCB空间,提升电路集成度;
  3. 宽温适应性:-55℃~+155℃的工作范围,可满足户外设备、工业高温车间、车载电子等对温度要求严格的场景;
  4. 低功耗适配:100mW额定功率适合信号调理、传感器接口、LED驱动辅助电路等低功耗场景,避免功率冗余导致的成本增加。

四、典型应用场景

RK73H1JTTD6802F因参数均衡、封装小巧,广泛应用于以下领域:

  • 消费电子:便携式音频设备的信号分压电阻、小型家电(智能插座、加湿器)的控制电路上拉/下拉电阻;
  • 工业控制:PLC数字输入接口电阻、PT100温度传感器信号调理电路分压电阻;
  • 汽车电子:车载仪表盘背光控制电路、胎压监测系统(TPMS)信号处理电阻、小型车载传感器接口电阻;
  • 通信设备:小型基站(Small Cell)射频前端辅助电路、光纤收发器信号衰减网络电阻。

五、可靠性与环境适应性

该电阻符合工业级可靠性要求:厚膜工艺使其具有较好的抗潮湿、抗腐蚀能力;在额定参数范围内,长期工作时阻值变化率通常小于0.1%/1000小时,满足设备长期稳定运行需求;同时,-55℃~+155℃的宽温范围,可适应从低温户外(北方冬季)到高温车载(发动机舱附近)的多种场景,无需额外降额设计。

综上,RK73H1JTTD6802F是一款兼顾精度、封装、可靠性的通用厚膜电阻,可满足多数中低端电子设备的核心电阻需求。

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
