CRWC08052K00FKEA 厚膜贴片电阻产品概述

一、产品基本身份与系列定位

CRCW08052K00FKEA是VISHAY(威世) 旗下CRCW系列的厚膜贴片电阻,属于中高精度小功率贴片电阻范畴。型号命名清晰对应核心属性:

  • CRCW:代表厚膜贴片电阻系列;
  • 0805:封装尺寸(英制0.08×0.05英寸,公制2.0×1.2mm);
  • 2K00:标称阻值2kΩ;
  • F:精度±1%(VISHAY电阻精度代码);
  • KEA:后缀包含温度系数(±100ppm/℃)、包装等参数。

该产品定位于通用精密型,兼顾成本与性能,适用于多数电子设备的信号调理、分压、滤波等电路。

二、核心电气性能参数解析

1. 阻值与精度

标称阻值2kΩ,精度±1%,满足一般精密电路对阻值准确性的需求(如传感器信号放大的偏置电阻、分压电路的比例控制)。无需额外校准即可实现稳定的电路特性。

2. 功率与电压

  • 额定功率125mW(1/8W):适配小信号电路的功率需求(如微控制器I/O口的上拉/下拉电阻);
  • 工作电压150V:覆盖中等电压场景(直流150V以内),需注意实际使用时电压×电流≤125mW(如150V时最大电流≈0.83mA)。

3. 温度系数

±100ppm/℃:表示温度每变化1℃,阻值变化百万分之一百。例如:

  • 从25℃升至155℃(工作上限),阻值变化量=130℃×100ppm=1.3%,结合±1%精度,整体漂移在可接受范围内,适合温度波动较大的环境。

三、封装结构与机械特性

1. 封装与工艺

采用0805贴片封装,体积小巧(仅2.0×1.2mm),可显著节省PCB空间,适配自动化SMT生产线(回流焊、波峰焊兼容),提升生产效率。

2. 结构与材料

基于氧化铝陶瓷基底(绝缘性好、热稳定性高),表面印刷钌基厚膜电阻浆料(低漂移、耐老化),两端引出镍/锡电极(焊接兼容性强)。

3. 环保合规

符合RoHS 2(2011/65/EU) 与REACH法规,不含铅、镉等有害物质,满足全球电子行业环保要求。

四、环境适应性与可靠性

1. 宽温工作范围

-55℃+155℃,覆盖**工业级(-40℃+85℃)** 与部分汽车级(-55℃~+150℃) 场景,可在高温环境(如汽车发动机舱、工业烤箱附近)稳定运行。

2. 耐环境性能

  • 耐湿度:厚膜结构抗潮湿腐蚀,通过IEC 60068-2-66(湿度循环)测试;
  • 抗振动:无引线设计减少振动应力,可承受10g/50-2000Hz振动(符合AEC-Q200标准);
  • 长期可靠性:阻值漂移率≤0.1%/1000小时(老化测试结果),保证设备长期稳定。

五、典型应用场景匹配

该产品因参数平衡,适用场景广泛:

  1. 工业控制:PLC信号调理、传感器(温度/压力)分压/滤波电阻;
  2. 汽车电子:仪表盘背光、车身控制模块(BCM)信号电阻;
  3. 消费电子:智能手机/平板电源滤波、音频信号调理电阻;
  4. 通信设备:基站偏置电路、路由器信号衰减电阻;
  5. 医疗仪器:血糖仪/血压计信号放大电路(依赖稳定阻值)。

六、品牌与合规性背书

VISHAY作为全球领先的电子元器件厂商,拥有50+年厚膜电阻生产经验,CRCW系列是其成熟稳定的核心产品线,广泛应用于苹果、华为、博世等企业的设备中。

该产品符合多项国际标准:

  • 电磁兼容:IEC 61000-4系列;
  • 汽车级:AEC-Q200(部分版本);
  • 环保:RoHS 2、REACH。

总结

CRCW08052K00FKEA是一款高性价比的厚膜贴片电阻,平衡了精度、功率、环境适应性与成本,适合多数电子设备的常规与精密电路需求,是工业、汽车、消费电子领域的可靠选择。

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
