SC0402F1004F2ANRH 厚膜贴片电阻产品概述

一、产品定位与核心参数

SC0402F1004F2ANRH是信维通信(Sunway)推出的通用型厚膜贴片电阻,主打小体积、高精度与稳定性能,适配高密度电路设计需求。核心参数明确:标称阻值1MΩ(10⁶Ω)、精度±1%、额定功率62.5mW、额定工作电压50V、温度系数±100ppm/℃,工作温度覆盖-55℃至+155℃,属于工业级温度范围的基础型贴片电阻,可满足多数常规电子设备的电路需求。

二、封装与尺寸规格

该电阻采用0402英寸封装(公制尺寸1.0mm×0.5mm×0.4mm,长×宽×高),是贴片电阻中体积最小的规格之一,适配高密度PCB布局(如智能手机主板、物联网模块等)。封装为表面贴装式,兼容回流焊、波峰焊等常规SMT工艺,焊接可靠性符合IPC-A-610标准;无引脚设计减少了寄生电感/电容,可提升电路高频性能,适合信号传输类电路。

三、电气性能参数详解

3.1 阻值与精度

标称阻值1MΩ,精度±1%,即实际阻值范围为990kΩ~1010kΩ,满足一般模拟电路、信号调理电路对阻值偏差的要求(无需超高精度如0.1%的场景)。型号中的“1004”为阻值代码(100×10⁴Ω=1MΩ),便于生产选型与库存管理。

3.2 功率与电压限制

额定功率62.5mW,额定工作电压50V,实际使用需同时满足两个限制条件(验证:50V²/1MΩ=2.5mW<62.5mW,说明电压限制更严格);短时间过载能力为1.25倍额定功率(约78.125mW),可应对瞬时功率波动(如电路启动瞬间的电流峰值)。

3.3 温度稳定性

温度系数±100ppm/℃,以25℃为基准温度,环境温度每变化1℃,阻值变化±100×10⁻⁶Ω/Ω。例如,155℃时阻值变化量为1MΩ×(155-25)×100ppm=13Ω,阻值范围999987Ω~1000013Ω,适合温度变化范围不大的一般环境(如室内设备、车载辅助电路)。

四、环境适应性与可靠性

4.1 工作温度范围

-55℃~+155℃,覆盖工业级设备的典型环境温度(如户外传感器、车载仪表盘),低温下无阻值漂移或封装开裂风险,高温下性能稳定,可满足多数应用场景的温度需求。

4.2 耐环境性能

  • 耐焊接热:回流焊峰值温度260℃(持续10s),无封装变形、阻值变化超标问题;
  • 湿度适应性:85℃/85%RH高湿环境下工作1000小时,阻值变化≤2%,满足潮湿地区设备需求;
  • 机械性能:抗振动(10~2000Hz,加速度2g)、抗冲击(1500g,0.5ms),适配便携式设备的跌落场景。

4.3 可靠性指标

额定功率下负载寿命1000小时,阻值变化≤1%;温度循环(-55℃~+155℃,500次循环)后,阻值变化≤0.5%,符合厚膜电阻的通用可靠性标准,可降低设备长期运行的故障风险。

五、典型应用场景

SC0402F1004F2ANRH因体积小、精度适中,广泛应用于以下场景:

  1. 消费电子:智能手机、平板电脑的电源管理模块、信号滤波电路;
  2. 物联网设备:低功耗传感器节点(温湿度、运动传感器)的信号调理;
  3. 小型工业控制:PLC模拟量输入输出模块、小型继电器驱动电路;
  4. 汽车电子:车载USB充电模块、仪表盘辅助显示电路(非安全关键系统);
  5. 医疗设备:便携血糖仪、血压计的信号放大与滤波电路。

六、品牌与质量保障

信维通信(Sunway)是国内领先的电子元器件制造商,该电阻符合RoHS 2.0、REACH等环保标准,无铅无卤;生产过程通过ISO9001质量管理体系与IATF16949汽车电子体系认证,每批次产品经过阻值、精度、温度系数全检,一致性达标率≥99.9%,可提供完整的质量检测报告与售后技术支持。

该产品平衡了体积、性能与成本,是高密度电路设计中基础电阻的优选方案。

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
