SC0805J2004F4ANRH产品概述

一、产品基本信息

SC0805J2004F4ANRH是信维通信(Sunway)推出的厚膜贴片电阻,采用行业标准0805英寸封装(对应公制2012尺寸,长2.0mm×宽1.2mm),属于高阻值、常规精度的表面贴装元件,广泛适配各类电子设备的信号调理、分压、限流等基础电路设计。

二、关键电气参数解析

该电阻的核心参数直接决定适用场景,具体如下:

  1. 阻值与精度:标称阻值2MΩ(代码“2004”表示:前三位“200”为有效数字,第四位“4”为×10⁴倍),精度±5%(行业J档),满足多数非超高精度电路的阻值需求;
  2. 功率与电压限制:额定功率125mW,最大工作电压150V。需注意电压优先级高于功率:根据公式(P=V^2/R)计算,150V下实际功率仅11.25mW(远低于额定值),因此实际使用中需严格控制电压不超过150V;
  3. 温度系数(TCR):±100ppm/℃,表示温度每变化1℃,阻值变化为标称值的百万分之一百。例如,从25℃(基准)升至125℃(变化100℃),阻值变化范围为±20kΩ,与±5%精度(±100kΩ)兼容,宽温环境下稳定性可控;
  4. 工作温度范围:-55℃~+155℃,覆盖工业级低温及消费电子高温场景,适应不同环境的温度波动。

三、封装与物理特性

采用0805贴片封装,具备以下优势:

  • 尺寸紧凑:2.0mm×1.2mm的小体积,适合高密度PCB设计,有效节省电路板空间;
  • 焊接兼容性:表面贴装工艺,可通过回流焊、波峰焊实现自动化生产,焊接效率高;
  • 厚膜工艺优势:通过丝网印刷、高温烧结制备电阻膜层,相比薄膜电阻成本更低、阻值范围宽(几欧至几兆欧),抗过流能力较强。

四、典型应用场景

基于高阻值、宽温特性,该电阻适用于:

  1. 信号调理电路:传感器信号的分压采样、微弱信号放大的偏置电阻;
  2. 电源模块:开关电源反馈分压、线性电源限流保护;
  3. 消费电子:手机、平板等便携设备的辅助电路(如按键背光、指示灯限流);
  4. 工业控制:PLC、传感器模块的信号隔离与分压电路;
  5. 汽车电子(非AEC-Q要求场景):车载辅助电路(如仪表盘背光、小功率负载限流)。

五、可靠性与环境适应性

  1. 温度稳定性:-55℃~+155℃宽温范围结合±100ppm/℃ TCR,极端温度下阻值漂移可控;
  2. 抗环境干扰:厚膜膜层致密,抗潮湿、抗污染能力较强,适合恶劣环境长期使用;
  3. 寿命特性:额定参数内使用时,平均无故障时间(MTBF)可达数万小时,满足多数电子设备寿命需求。

六、选型与使用注意事项

为确保电路可靠性,需注意:

  1. 功率降额:建议实际功率不超过额定值的80%(100mW),避免长期过载导致阻值漂移;
  2. 电压限制:严格控制工作电压≤150V,防止电压击穿;
  3. 温度补偿:精密测量场景需结合TCR进行软件/硬件补偿;
  4. 焊接规范:回流焊峰值温度240℃~260℃(时间≤10s),避免过热损坏膜层;
  5. 存储条件:未焊接电阻需存于干燥环境(湿度≤60%),温度0℃~40℃,避免潮湿暴露。

该产品凭借成本优势、宽温特性及高阻值覆盖,成为电子设备基础电路的高性价比选择。

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
