SC0603J4702F2BNRH 厚膜电阻器产品概述

该电阻器为Sunway(信维通信)推出的0603封装通用厚膜贴片电阻,针对中低功率电子电路的稳定分压、限流、信号调理等需求设计,兼具小型化、高可靠性与成本优势,适用于工业控制、消费电子、通信设备等多领域应用。

一、核心身份与设计定位

SC0603J4702F2BNRH属于厚膜电阻范畴,采用陶瓷基底+厚膜电阻浆料烧结工艺制造,区别于薄膜电阻的高精度特性,更侧重批量应用的稳定性与性价比。其型号命名隐含关键信息:

  • “SC”为Sunway品牌专属代码;
  • “0603”对应英制贴片封装尺寸(公制1.6mm×0.8mm);
  • “J”代表精度等级±5%(工业通用精度);
  • “4702”为阻值标识(对应标称值47kΩ);
  • 后缀“F2BNRH”涉及温度系数、封装细节及生产批次。

二、基础电性能参数详解

该电阻器的电性能参数覆盖多数通用电路的核心需求,关键指标明确:

  1. 阻值与精度:标称阻值47kΩ,精度±5%(J级),无需额外校准即可满足多数电路的功能需求;
  2. 功率与电压:额定功率100mW,最大工作电压75V。需注意功率降额原则:环境温度超过25℃时,功率需按温度系数线性降额(如125℃时额定功率降至约60mW),避免过功耗导致阻值漂移;
  3. 温度系数(TCR):±100ppm/℃,即温度每变化1℃,阻值变化±0.01%。在-55℃~+155℃范围内,最大阻值漂移约±1.1%(110℃温差×100ppm),符合厚膜电阻的常规稳定性要求;
  4. 频率特性:厚膜电阻的高频特性略逊于薄膜电阻,但在100MHz以下信号电路中,阻值变化可忽略,满足中低频应用需求。

三、封装与物理特性

采用0603贴片封装(公制1608),尺寸小巧(1.6mm×0.8mm×0.45mm典型高度),适配SMT自动化生产,兼容回流焊、波峰焊等工艺:

  • 基底材料:氧化铝陶瓷(Al₂O₃),导热性良好,可快速散发热量;
  • 电极结构:银钯合金电极(Ag-Pd),焊接兼容性强,不易出现虚焊;
  • 保护层:玻璃釉涂层,耐湿、耐化学腐蚀,有效防止电阻浆料氧化,提升长期可靠性。

四、环境适应性与可靠性

该电阻器的环境适应性覆盖工业级及扩展应用场景:

  1. 工作温度范围:-55℃+155℃,远超商业级(0℃+70℃)与工业级(-40℃~+85℃)标准,可在高温环境(如汽车发动机舱周边、工业烤箱内)稳定工作;
  2. 可靠性指标:符合IEC 61041《电子设备用固定电阻器总规范》,典型表现为:
    • 负载寿命(25℃、额定功率下1000小时):阻值变化≤±1%;
    • 湿负荷寿命(40℃、95%RH下1000小时):阻值变化≤±2%;
    • 温度循环(-55℃~+155℃,500次循环):无开路/短路,阻值变化≤±1.5%;
  3. 环保要求:符合RoHS 2.0(无铅、无镉、无汞)与REACH法规,满足欧盟市场准入要求。

五、典型应用场景

基于参数特性,该电阻器适用于以下场景:

  1. 消费电子:智能手机/平板的电源分压电路、音频信号调理、LED背光驱动限流;
  2. 工业控制:PLC模块的模拟量接口、传感器信号放大、小型电机驱动限流;
  3. 通信设备:路由器/交换机的信号匹配网络、基站辅助电路分压;
  4. 汽车电子(非安全级):倒车雷达信号滤波、中控面板按键检测;
  5. 电源适配器:轻载反馈调节、EMI滤波分压。

六、品牌与品质保障

Sunway(信维通信)作为国内被动元件头部企业,具备完整厚膜电阻生产线,产品通过ISO 9001、ISO 14001认证,供货周期稳定(常规1-2周,批量可协商),且提供3年非人为损坏质保,适合中大型厂商批量采购。

该电阻器以“通用稳定、成本可控、环境适应性强”为核心优势,是替代同类进口厚膜电阻的优质选择,可覆盖多数中低功率电子电路的基础应用需求。

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
