SC0402J47R0F2ANRH 厚膜贴片电阻产品概述

SC0402J47R0F2ANRH是Sunway(信维通信)推出的一款小型化厚膜贴片电阻,采用0402封装,专为高密度电路设计,兼顾可靠性与成本优势,广泛适配消费电子、智能穿戴等领域的常规应用需求。

一、产品基本属性与规格参数

该电阻的核心属性可从基础属性和关键性能参数两方面明确:

1. 基础属性

  • 封装类型:0402英制贴片封装(对应公制尺寸约1.0mm×0.5mm),属于微型贴片电阻范畴;
  • 电阻类型:厚膜贴片电阻(通过丝网印刷电阻浆料烧结而成,兼顾成本与可靠性);
  • 品牌:Sunway(信维通信),国内射频及被动元件领域的主流制造商,具备成熟的自动化生产能力。

2. 关键性能参数(额定值)

参数项 规格值 说明 标称阻值 47Ω 欧姆标称值,满足常规分压/限流需求 精度等级 ±5% 商业级常规精度,适配多数非精密场景 额定功率 62.5mW 0402封装厚膜电阻的典型功率规格 额定工作电压 50V(DC/AC) 直流/交流有效值,覆盖低压电路范围 温度系数(TCR) ±100ppm/℃ 温度每变化1℃,阻值变化±0.01% 工作温度范围 -55℃~+155℃ 覆盖工业级及部分车载环境的温度需求

二、核心性能特点

该电阻在小型化、宽温可靠性及成本平衡上具备明显优势:

1. 微型化高集成度

0402封装体积仅为1.0mm×0.5mm,可显著降低电路空间占用,适配智能手机、智能穿戴等便携式设备的高密度布局。

2. 宽温稳定可靠

-55℃~+155℃的工作温度范围,使产品可在极端环境(如高温工业现场、低温户外场景)下稳定工作;±100ppm/℃的温度系数,确保阻值漂移控制在工程可接受范围内。

3. 功率与电压适配性

  • 62.5mW额定功率满足小信号电路(如传感器信号调理、MCU周边限流)的功率需求;
  • 50V额定电压覆盖低压直流/交流电路的常规电压范围,无需额外降额即可适配多数消费电子场景。

4. 厚膜工艺优势

相比薄膜电阻,厚膜电阻成本更低,且具备较好的耐过载能力(短时间可承受1.5~2倍额定功率),长期使用可靠性高。

5. 批量一致性好

信维通信的自动化生产工艺确保产品阻值、温度系数等参数的批量一致性,减少电路调试复杂度。

三、典型应用场景

SC0402J47R0F2ANRH的参数特性使其适配多领域的常规电路:

1. 消费电子领域

  • 智能手机/平板电脑:电源管理电路(电池分压检测、充电限流)、音频电路(信号衰减、滤波);
  • 家用电子:智能音箱、机顶盒的信号匹配电路。

2. 智能穿戴设备

  • 智能手表/手环:心率、血氧传感器的信号调理电路、低功耗蓝牙模块周边;
  • 运动手环:计步传感器的信号放大电路。

3. 工业控制领域

  • 小型PLC:输入输出接口的限流电阻;
  • 传感器模块:温度、压力传感器的信号衰减电路。

4. 物联网(IoT)设备

  • 低功耗IoT节点:电源滤波、数据传输电路的信号匹配;
  • 智能家居:智能插座、传感器节点的辅助电路。

四、品牌与可靠性保障

Sunway(信维通信)作为国内领先的电子元器件制造商,其产品具备完善的可靠性保障:

1. 环保合规

产品符合RoHS 2.0(无铅环保)、REACH(有害物质限制)等国际标准,满足出口及国内市场的合规要求。

2. 可靠性测试

通过多项行业标准测试:

  • 高温存储:155℃×1000小时,阻值变化率≤±1%;
  • 温度循环:-55℃~+155℃×500次,无开路/短路;
  • 湿度老化:85℃/85%RH×1000小时,阻值变化率≤±1%。

3. 行业标准适配

符合IEC 61000-4(电磁兼容)、JIS C 5201(电阻器标准)等行业规范,可适配不同领域的应用要求。

五、选型与使用注意事项

为确保产品性能稳定,需注意以下要点:

1. 功率/电压降额

  • 实际功率建议不超过额定功率的80%(即50mW),避免过载导致阻值漂移;
  • 实际电压建议不超过额定电压的70%80%(35V40V),防止电击穿。

2. 焊接工艺

采用回流焊工艺(避免手工焊接),遵循信维推荐的回流曲线:

  • 峰值温度:230℃~245℃;
  • 焊接时间:10秒~30秒(峰值温度区间)。

3. 存储条件

存储于常温干燥环境(温度25℃±5℃,湿度40%~60%),避免长期暴露在高湿环境(湿度>85%)导致引脚氧化。

4. 静电防护

虽厚膜电阻抗静电能力优于薄膜,但组装过程中需采取ESD防护(接地工作台、防静电包装),避免静电损伤。

SC0402J47R0F2ANRH以其小型化、宽温可靠及成本优势,成为消费电子、智能穿戴等领域常规电路的理想被动元件选型。

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
