CRCW040210M0FKEDC 厚膜贴片电阻产品概述

CRCW040210M0FKEDC是VISHAY(威世) 旗下CRCW系列的精密厚膜贴片电阻,以0402小封装、10MΩ±1%高精度为核心特点,兼顾宽温区适应性与小功率场景需求,是工业控制、汽车电子、消费电子等领域的经典选型之一。

一、产品核心身份与品牌背书

CRCW系列是VISHAY厚膜电阻的主力产品线,覆盖从0402到2512全系列封装,阻值范围从1Ω到100MΩ,精度从±0.1%到±5%不等。本型号的编码逻辑清晰:

  • CRCW:VISHAY厚膜贴片电阻系列标识;
  • 0402:英制封装尺寸(对应公制1005,即1.0mm×0.5mm);
  • 10M0:标称阻值10MΩ(“0”为精度代码前缀);
  • FKEDC:参数代码,对应±1%精度、±100ppm/℃温度系数等关键性能。

VISHAY作为全球电子元器件龙头,其厚膜电阻采用96%氧化铝陶瓷基片+厚膜电阻浆料工艺,结合激光微调技术,保证阻值一致性与长期稳定性,符合RoHS、REACH等环保标准,部分批次通过汽车级AEC-Q200认证。

二、关键电气性能参数解析

本型号针对小功率精密电路优化,核心参数精准匹配场景需求:

  1. 阻值与精度:10MΩ±1%——满足运算放大器偏置、信号分压等对阻值精度要求较高的场景,避免因阻值偏差导致的信号失真;
  2. 功率额定值:62.5mW——0402封装的常规功率上限,适合低功耗电路(如物联网传感器、电池供电设备)的信号调理;
  3. 工作电压:50V(直流/交流峰值)——可覆盖大部分低压电路的电压范围,避免电击穿风险;
  4. 温度系数(TCR):±100ppm/℃——在-55℃~+155℃温区内,阻值漂移控制在合理范围(如125℃时漂移约±1.25%),满足宽温环境下的性能稳定。

三、封装与物理特性

0402封装是高密度PCB设计的核心选型,具有以下特点:

  • 尺寸紧凑:1.0mm×0.5mm×0.4mm(典型厚度),可大幅减少电路板空间占用,适合智能手机、智能穿戴等便携设备;
  • 工艺兼容性:表面贴装工艺,兼容回流焊、激光焊,端电极采用镍/锡(Ni/Sn)镀层,焊接牢固且抗氧化;
  • 热稳定性:氧化铝陶瓷基片热导率优于普通树脂基片,可快速散发热量,降低温度对阻值的影响。

四、典型应用场景

结合参数与封装特点,本型号适用于以下场景:

  1. 精密模拟电路:运算放大器(如OPA系列)的偏置电阻、差分放大电路的分压网络;
  2. 低功耗物联网设备:传感器节点(温湿度、压力传感器)的信号调理、电池供电设备的限流电路;
  3. 汽车电子:发动机舱内的温度传感器信号处理、车载中控的低压信号链路(-55℃~+155℃温区适配);
  4. 工业控制:PLC模块的模拟量输入电路、电机驱动的反馈电阻;
  5. 消费电子:智能手机的音频模块、平板的触控信号处理电路(小封装适配高密度设计)。

五、可靠性与环境适应性

VISHAY厚膜电阻的可靠性经过严格测试,本型号满足:

  • 宽温工作:-55℃~+155℃,符合AEC-Q200标准(部分批次),可应对极端温度环境;
  • 长期稳定性:1000小时负载寿命测试(125℃、额定功率),阻值变化率≤±0.5%,电流噪声≤-40dB;
  • 湿度耐受性:厚膜工艺对湿度敏感性低于碳膜电阻,85℃/85%RH环境下测试2000小时,阻值漂移≤±1%;
  • ESD防护:通过HBM 2kV ESD测试,满足一般电子设备的静电防护需求。

六、应用注意事项

为保证性能稳定,需注意以下几点:

  1. 功率降额:环境温度超70℃时,需按VISHAY降额曲线调整功率(如125℃时降额至50%);脉冲功率场景需计算峰值功率,避免超过额定值;
  2. 焊接工艺:回流焊峰值温度控制在240℃~250℃,时间不超10秒;0402封装贴装精度需控制在±0.05mm以内,避免虚焊;
  3. 静电防护:生产、测试过程中需佩戴防静电手环,使用防静电工作台,避免静电损坏电阻;
  4. 阻值匹配:若需多路电阻匹配(如电桥电路),建议选择同批次产品,保证阻值一致性。

综上,CRCW040210M0FKEDC以小封装、高精度、宽温区为核心优势,兼顾成本与性能,是中小功率精密电路的高性价比选型,广泛适配多行业应用需求。

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.
