SC1206J4702F8ANRH厚膜固定电阻器产品概述

SC1206J4702F8ANRH是信维通信(Sunway)推出的一款通用型表面贴装厚膜固定电阻器,采用1206(英制)封装,针对消费电子、工业控制及通信设备等领域的常规电路需求设计,兼顾成本控制与性能稳定性。

一、核心应用场景定位

该电阻器属于中低端通用型,主要适配以下场景:

  • 消费电子:手机、平板的电源管理模块、音频信号调理电路;
  • 通信设备:路由器、交换机的信号分压、限流回路;
  • 工业控制:PLC输入输出接口、传感器信号预处理电路(宽温范围适配工业环境);
  • 小型家电:智能插座、加湿器的控制电路中的分压/限流元件。

二、关键电气参数详解

1. 阻值与精度

标称阻值为47kΩ,精度等级为±5%(型号中“J”为精度代码,对应E24系列电阻的±5%公差),适合对阻值精度要求不高的通用电路,无需额外校准即可满足大部分常规需求。

2. 功率与电压承载

  • 额定功率:250mW(1/4W),匹配1206封装的常规功率规格,可稳定承载0.25W以内的功率消耗;
  • 最大工作电压:200V,使用时需注意:实际工作电压不得超过200V,且功率消耗不得超过250mW(例如:当工作电压为100V时,功率消耗为100²/47000≈212mW,符合要求;若电压达到200V,功率消耗为200²/47000≈851mW,远超额定功率,需避免)。

3. 温度特性

  • 温度系数(TCR):±100ppm/℃,表示温度每变化1℃,阻值变化约为47kΩ×100ppm=4.7Ω,属于通用型温漂水平,适合温度变化幅度不大(如室内环境)或对温漂敏感度低的电路;
  • 工作温度范围:-55℃~+155℃,覆盖工业级温度标准,可在低温(如寒冷地区户外设备)或高温(如密闭机箱内)环境下稳定工作。

三、封装与物理特性

采用1206(英制)封装(对应公制3216,尺寸约3.2mm×1.6mm),具有以下特点:

  • 表面贴装兼容:适配常规SMT贴片机,可实现自动化批量生产,降低组装成本;
  • 高密度设计:小尺寸适合PCB高密度布局,满足小型化产品需求;
  • 厚膜工艺优势:通过丝网印刷、烧结工艺制成,成本低于薄膜电阻,且抗冲击振动性能优于碳膜电阻,长期使用稳定性可靠。

四、可靠性与环保特性

信维通信作为国内知名元器件厂商,该产品通过以下可靠性测试:

  • 高温老化测试(155℃下1000小时):阻值变化率≤±1%;
  • 温度循环测试(-55℃~+155℃,500次循环):无开路/短路,阻值变化≤±0.5%;
  • 湿度测试(85℃/85%RH,1000小时):阻值变化≤±1%。

同时符合RoHS 2.0环保标准,不含铅、镉、汞等有害重金属,适配欧盟及国内环保要求。

五、典型电路应用示例

  1. LED限流电路:在小功率LED(如指示灯)驱动中,串联该电阻限制电流(例如:LED工作电压2V,电源5V,需限流电阻47kΩ时,电流≈(5-2)/47000≈63μA,符合小功率LED需求);
  2. 音频分压电路:在耳机接口信号调理中,通过47kΩ电阻分压,将高电平信号衰减至耳机可接受范围;
  3. RC滤波电路:与100nF电容配合组成低通滤波,滤除1/(2π×47000×100e-9)≈33.8Hz以上的高频噪声;
  4. 工业传感器接口:在温度传感器(如PT100)信号调理中,作为分压电阻调整输出电平,适配PLC输入模块。

该产品以高性价比、宽温度范围及稳定可靠性,成为通用电路设计中的常规选择,适合对成本敏感且无需高精度的电子设备。

Sourcing availability signal

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
