SC0805F4700F4ANRH 厚膜贴片电阻产品概述

一、产品基本属性

SC0805F4700F4ANRH是信维通信(Sunway)推出的0805封装厚膜贴片电阻,属于标准化中低功率元件,核心功能覆盖电子电路中的阻抗匹配、分压、限流、信号滤波等基础场景。其以紧凑体积、稳定性能及成本优势,成为消费电子、工业控制、通信设备等领域的常用选型之一。

二、核心性能参数详解

该电阻的参数设计适配多数常规电子系统需求,关键指标如下:

  1. 阻值与精度:标称阻值470Ω,精度±1%——满足民用/工业级电路对阻值偏差的要求,无需额外筛选即可用于普通信号处理、电源分压等场景;
  2. 功率与电压:额定功率125mW,最大工作电压150V——在0805封装中属于常规功率等级,可覆盖小功率直流/交流电路负载,电压参数确保高压场景下的绝缘可靠性;
  3. 温度特性:温度系数±100ppm/℃——表示温度每变化1℃,阻值变化约0.047Ω(470Ω×100e-6),属于厚膜电阻典型水平,适配宽温区稳定性需求;
  4. 工作温区:-55℃+155℃——覆盖工业级(-4085℃)及部分汽车辅助系统的温度范围,可应对极端环境;
  5. 封装尺寸:0805(英制,公制2012)——体积小巧(长2.0mm×宽1.2mm),适配高密度PCB设计,适合便携式设备小型化需求。

三、典型应用场景

该电阻凭借参数适配性,广泛应用于以下领域:

  1. 消费电子:智能手机主板射频前端阻抗匹配、电源管理模块电池电量检测分压、智能音箱控制板限流;
  2. 工业控制:PLC模拟量输入通道限流、传感器信号调理电路阻抗匹配、小型电机驱动电路分压;
  3. 通信设备:路由器高速信号链路终端电阻、交换机电源模块过流保护限流、基站辅助电路滤波;
  4. 小型家电:扫地机器人传感器信号放大反馈、空气净化器控制板分压、微波炉电源限流;
  5. 汽车辅助系统:车载显示屏背光驱动分压、车身控制模块信号滤波(注:非安全关键场景需确认认证)。

四、品牌与可靠性优势

  1. 工艺特点:采用厚膜印刷工艺,相比碳膜电阻稳定性更强,相比薄膜电阻成本更低,抗机械冲击、振动能力突出,适合批量生产;
  2. 品牌保障:信维通信为国内射频及被动元件知名企业,产品通过RoHS环保认证,经高温存储、温度循环、湿度测试等可靠性验证;
  3. 一致性:批量产品阻值、温度系数一致性较好,减少电路调试筛选工作量,提升生产效率。

五、选型与使用注意事项

  1. 功率降额:实际使用功率建议不超过额定值的80%(≤100mW),避免长期过载导致阻值漂移;
  2. 焊接要求:回流焊峰值温度≤260℃,回流时间≤10秒;手工焊温度≤350℃,焊接时间≤3秒,避免损坏电阻;
  3. 存储条件:未使用电阻存储于1535℃、4060%RH环境,避免受潮或高温老化;
  4. 高压场景:接近150V工作电压时,需确保PCB爬电距离符合安全标准,防止漏电;
  5. 替换参考:若需更高精度(±0.1%)或更低温漂(±50ppm/℃),可选择薄膜电阻(成本略增);若需更大功率,可升级至1206封装。

该产品以平衡的性能、紧凑封装及成本优势,成为470Ω阻值的优选元件,适配各类中低功率电子设备的基础电路需求。

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
