RK73H1ETTP5602F厚膜贴片电阻器产品概述

一、产品基本定位

RK73H1ETTP5602F是日本KOA公司推出的一款厚膜贴片电阻器,属于常规高精度小功率系列产品。该电阻针对高密度、低功耗电子电路设计,兼具成本优势与稳定性能,广泛适配消费电子、工业控制、物联网等多领域应用,是小型化电子设备的常用被动元器件之一。

二、核心技术参数

该电阻的核心参数明确且适配主流电路需求,具体如下:

  • 阻值与精度:标称阻值56kΩ,精度±1%,可满足多数信号调理、分压电路对阻值偏差的控制要求;
  • 功率与电压:额定功率63mW(即1/10W),工作电压上限75V,在额定参数范围内可长期稳定工作(需注意功率与电压的降额使用原则,避免过负荷);
  • 温度特性:温度系数(TCR)±100ppm/℃,即温度每变化1℃,阻值变化约±0.01%;工作温度范围覆盖-55℃~+155℃,支持工业级极端环境;
  • 封装类型:0402封装(英制尺寸),体积紧凑,适配高密度PCB布局。

三、封装与尺寸规格

RK73H1ETTP5602F采用0402封装(公制对应1005),具体尺寸参数为:

  • 长度:约1.02mm(0.04英寸);
  • 宽度:约0.51mm(0.02英寸);
  • 厚度:约0.35mm(典型值)。

小体积设计可显著节省PCB布局空间,适合智能手机、可穿戴设备、小型工业模块等对集成度要求较高的产品,能有效降低设备整体尺寸。

四、性能优势分析

1. 精度与稳定性兼顾

±1%的阻值精度满足多数电路的匹配需求(如传感器信号分压、音频接口匹配);±100ppm/℃的温度系数在常规环境温度波动(如25℃±20℃)下,阻值偏差可控制在±0.2%以内,避免因温度变化导致电路性能漂移。

2. 宽温工作能力

-55℃~+155℃的工作温度范围覆盖工业级环境(如户外设备、车载辅助电路),可在极端低温(如北方冬季户外)或高温(如工业烤箱附近)场景下长期可靠运行,无需额外温控设计。

3. 小功率适配性

63mW的额定功率适配低功耗电路(如蓝牙模块偏置电路、物联网传感器节点),多数低功耗应用无需降额使用即可满足需求,简化电路设计流程。

4. 厚膜工艺可靠性

采用成熟的厚膜丝网印刷工艺,具备优异的耐湿性(85℃/85%RH环境下1000小时阻值变化≤0.5%)、抗静电能力(ESD耐受≥2kV),且批次一致性好,适合批量生产的电子设备厂商。

五、典型应用场景

该电阻因体积小、精度稳定,广泛应用于以下领域:

  1. 消费电子:智能手机音频接口、平板电脑信号匹配、可穿戴设备(如智能手环)的传感器电路;
  2. 工业控制:小型PLC I/O接口、温度传感器信号调理、工业电源的分压网络;
  3. 物联网模块:蓝牙/WiFi模块的偏置电路、低功耗传感器节点的信号滤波;
  4. 汽车电子(辅助级):车载仪表盘背光控制、车门传感器接口分压;
  5. 通信设备:小型基站的信号匹配电阻、家用路由器的电源管理模块分压。

六、品牌与合规性

KOA作为全球被动元器件领域的知名厂商,其产品生产过程严格遵循ISO 9001质量管理体系,批次一致性达行业领先水平。RK73H1ETTP5602F符合RoHS 2.0(无铅)、REACH等环保法规要求,可满足欧盟、中国等地区的市场准入条件,适合全球范围内的电子设备研发与生产。

该产品凭借平衡的性能与成本优势,成为众多电子厂商的首选厚膜电阻之一,可有效支撑小型化、低功耗电子设备的稳定运行。

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
