RK73H1ETTP4702F 产品概述

一、产品简介

RK73H1ETTP4702F 是 KOA 出品的厚膜贴片电阻,封装为 402(俗称 0402),标称阻值 47kΩ,精度 ±1%,额定功率 100mW,工作电压 75V,温度系数(TCR)±100ppm/℃,工作温度范围 -55℃ 至 +155℃。该型号以小型化、高可靠性和平衡的温度稳定性为主要特点,适用于空间受限且对精度、稳定性有中等要求的电子产品。

二、主要技术参数

  • 电阻类型:厚膜电阻(Chip, thick film)
  • 阻值:47kΩ
  • 精度:±1%
  • 额定功率:100mW
  • 额定工作电压:75V
  • 温度系数:±100ppm/℃
  • 工作温度:-55℃ ~ +155℃
  • 封装:402(0402)
  • 品牌:KOA

三、关键特性与优势

  • 体积小、适合高密度贴装:0402 封装可用于尺寸受限的移动设备、可穿戴设备及高密度板设计。
  • 精度与稳定性平衡:±1% 精度配合 ±100ppm/℃ 的温漂,适合计时、分压和一般精密要求的电路。
  • 宽温工作范围:-55℃~+155℃ 满足工业级及恶劣环境下的可靠性需求。
  • 良好的通用性:厚膜工艺兼顾成本与性能,适合量产与成本敏感型应用。

四、典型应用场景

  • 电阻分压、拉/下拉电阻与偏置网络
  • 信号处理与滤波网络中的阻值元件
  • 便携式消费电子与可穿戴设备
  • 工业控制及测量仪表的通用电阻需求
  • PCB 空间受限处的一般用途电阻

五、安装与使用建议

  • 温度降额:虽额定功率为 100mW,但在高环境温度下需按厂方提供的降额曲线进行设计,以防过热。
  • 电压考虑:工作电压 75V 为单片限制,若电路电压更高应采用串联或更高耐压器件。
  • 焊接工艺:适用于常规回流焊工艺,推荐遵循 KOA 或行业标准的回流曲线与清洗流程,避免长期浸入强腐蚀性清洗液。
  • 布局与焊盘:因封装微小,遵循厂商或 IPC 推荐的焊盘尺寸与焊膏量,以保证焊点可靠性与阻值稳定。

六、可靠性与存储

  • 本型号具备宽温与工业级耐受性,适合长期在振动、温度循环环境中使用。
  • 存储建议干燥保存,避免受潮和强酸碱、强腐蚀性气体环境,以保持元件的焊接与电气特性。

七、选型与订购参考

型号:RK73H1ETTP4702F(KOA)— 请在批量采购或关键应用前索取 KOA 官方数据手册以获取完整的降额曲线、机械尺寸图、焊接规范及可靠性测试数据,确保在目标应用中满足所有电气与环境要求。

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
