RK73H1ETTP5101F 产品概述

一、产品简介

RK73H1ETTP5101F 是 KOA 推出的贴片厚膜电阻,阻值 5.1 kΩ,精度 ±1%,额定功率 100 mW,适用于空间受限且对精度和温度稳定性有一定要求的电子产品。封装标称 0402(402),尺寸约 1.0 mm × 0.5 mm,符合表贴工艺,便于高速表面贴装和回流焊接。

二、主要参数

  • 电阻类型:厚膜电阻(Thick film)
  • 阻值:5.1 kΩ(5101)
  • 精度:±1%
  • 额定功率:100 mW(常温下)
  • 最高工作电压:75 V
  • 温度系数(TCR):±100 ppm/°C
  • 工作温度范围:-55 °C ~ +155 °C
  • 封装:0402(402,约 1.0 × 0.5 mm)
  • 品牌:KOA

三、特点与优势

  1. 小型化:0402 封装体积小,适合高密度贴装和小型化产品设计。
  2. 精度稳定:±1% 精度满足多数模拟、测量和滤波电路的需求,对阻值配对和分压精度有较好保证。
  3. 宽温度范围:-55 ℃ 至 +155 ℃ 的工作温度范围,适合工业级和拓展温度应用。
  4. 良好的一致性与可制造性:厚膜制造工艺成熟,适合大批量生产,批次一致性好。
  5. 耐环境性:典型厚膜电阻具有对湿热、温度循环的良好耐受性,适合多数工业和消费电子场合。

四、典型应用场景

  • 移动设备与可穿戴设备中的分压、电流检测电路;
  • 工业控制和传感器前端的信号调理;
  • 汽车车载电子(在满足车规认证前提下用于辅助电路);
  • 通信设备、网络终端的偏置与滤波电路;
  • 各类消费电子产品中要求小体积与中等功率的通用电阻位置。

五、封装与焊接注意事项

  • 回流焊:建议按 KOA 或通用 SMT 回流焊曲线进行焊接,遵循 PCB 及元件制造商提供的峰值温度和保温时间;避免超出推荐峰值温度以防过热造成性能退化。
  • PCB 设计:由于 0402 体积小,建议合理设计焊盘和过孔,保证良好附着力与可重复焊接性。
  • 清洗与处理:厚膜电阻对常规溶剂和清洗工艺一般耐受良好,但应避免长期浸泡强酸强碱;装配与搬运时注意避免机械冲击和端电极刮擦。
  • 功率降额:高温工作时需考虑功率随温度降额(具体降额曲线请参考 KOA 官方数据手册),以防过载导致寿命缩短或失效。

六、可靠性与环境性能

RK73 系列产品普遍通过并符合常见电子元器件的可靠性测试项,包括温度循环、高温存储、湿热负荷等;工作温度范围和 ±100 ppm/°C 的 TCR 使其在温度变化下维持较稳定的阻值表现。用于关键或严苛环境(如车规级、医疗级)时,建议参考 KOA 的详细可靠性报告或选择专用车规型号。

七、订购信息与替代建议

  • 型号:RK73H1ETTP5101F,品牌 KOA,0402 封装。
  • 订购时请确认包装形式(卷带包装等)、批次和是否含有 RoHS/无铅标识。
  • 若需要更高精度(±0.5%)、更低 TCR 或更高功率,可考虑 KOA 或其他厂家相邻系列替代型号,选型时应权衡封装尺寸、功率和温度特性。

如需完整的电气规格表、回流焊曲线或可靠性测试数据,请参照 KOA 官方数据手册或提供具体应用工况以便给出更精确的选型与布局建议。

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
