SC0805J4701F4ANRH 厚膜贴片电阻产品概述

一、产品基本定位与核心参数

SC0805J4701F4ANRH是信维通信(Sunway)推出的0805封装通用厚膜贴片电阻,针对中小功率电路设计,平衡了性能、成本与可靠性。核心参数清晰覆盖基础电子系统需求:

  • 阻值:4.7kΩ(标识代码4701,对应E24系列标准阻值)
  • 精度:±5%(J级精度,无需额外校准即可满足普通电路功能)
  • 功率:125mW(0805封装典型功率等级)
  • 工作电压:150V(额定电压,需结合功率匹配使用)
  • 温度系数:±100ppm/℃(阻值随温度变化的漂移率)
  • 工作温度:-55℃~+155℃(宽温适应性,覆盖工业级场景)

二、关键性能指标解析

1. 阻值与精度

4.7kΩ是电子电路中分压、限流、偏置的常用阻值,适配多数模拟信号调理(如音频放大偏置)、电源反馈(如DC-DC输出调节)场景。±5%精度属于通用级,避免了精密电阻的成本冗余,适合对阻值稳定性要求不苛刻的电路。

2. 功率与电压限制

额定功率125mW是0805厚膜电阻的典型值,可支撑中小信号电流(如最大电流≈5.2mA时,功耗未超额定)。需注意:实际电压受功率约束——若仅按150V计算,150V²/4.7kΩ≈4.9W(远大于125mW),因此使用时需以「功率≤125mW」为核心限制。

3. 温度特性

±100ppm/℃的温度系数表示:温度每变化1℃,阻值漂移±0.01%。例如,在-55℃到+100℃的宽温范围内,阻值最大漂移仅±1.55%,可满足工业户外、车载辅助系统等高低温场景的稳定性需求。

4. 环境适应性

工作温度覆盖-55℃+155℃,超过消费电子(0℃70℃)的常规要求,适配工业控制、汽车电子等对环境耐受性较高的领域,减少因温度变化导致的电路失效风险。

三、封装与物理特性

  • 封装形式:0805(英制0.08″×0.05″,公制2.0mm×1.2mm),小型化设计适合高密度PCB布局,兼容自动化SMT生产线;
  • 制造工艺:厚膜工艺(丝网印刷电阻浆料于氧化铝陶瓷基片,高温烧结而成),兼具成本优势与抗冲击振动能力(优于薄膜电阻);
  • 品牌品质:信维通信为国内射频与被动元件头部厂商,产品通过ISO9001、IATF16949认证,符合RoHS无铅环保要求。

四、典型应用场景

SC0805J4701F4ANRH因参数均衡,广泛应用于:

  1. 消费电子:手机/平板的音频偏置、智能穿戴的传感器接口;
  2. 工业控制:温度/压力传感器的信号分压、PLC输入电路限流;
  3. 汽车电子:车载仪表盘背光限流、车门传感器接口(需结合整车温度验证);
  4. 通信设备:基站射频单元的功率放大器偏置电阻;
  5. 电源管理:DC-DC转换器的反馈分压(如5V转3.3V的输出调节)。

五、使用注意事项

  1. 功率匹配:实际电路功耗需严格低于125mW,避免过功率烧毁;
  2. 焊接工艺:SMT回流焊需遵循信维推荐曲线(峰值温度240℃~260℃,峰值时间≤10秒),避免高温损坏;
  3. 存储条件:未焊接电阻存储于常温干燥环境(25℃±5℃,湿度≤60%),防止受潮影响焊接可靠性;
  4. 精度升级:若电路需更高精度(如精密测量),需替换为±1%、±0.1%等级的电阻。

该产品以成熟工艺与可靠参数,成为中小功率电路的高性价比选择,适配多领域电子系统的基础设计需求。

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
