CRCW120647K0FKEA 产品概述

一、产品简介

CRCW120647K0FKEA 是 VISHAY(威世)旗下 CRCW 系列的一款厚膜贴片电阻,阻值 47 kΩ,精度 ±1%,额定功率 1/4 W(250 mW),工作电压 200 V,温度系数(TCR)±100 ppm/℃。封装为 1206(英制),适用于表面贴装工业批量生产场景,型号标识简洁,产品描述常见为 “RES SMD 47K OHM 1% 1/4W”。

二、主要技术参数

  • 电阻类型:厚膜(Thick Film)SMD 电阻
  • 标称阻值:47 kΩ(47K0)
  • 精度:±1%(F)
  • 额定功率:0.25 W(250 mW,通常以 +70℃ 为基准)
  • 最大工作电压:200 V
  • 温度系数:±100 ppm/℃
  • 工作温度范围:-55 ℃ 至 +155 ℃
  • 封装尺寸:1206(约 3.2 mm × 1.6 mm)
  • 品牌:VISHAY(威世)
  • RoHS 合规:符合常见环保要求(具体请参照官方数据表)

三、产品特点与优点

  • 精度高:±1% 精度满足多数精密分压、滤波、偏置等电路要求。
  • 稳定性好:厚膜工艺结合严谨的生产过程,使得在宽温度范围内具有良好的电阻稳定性(TCR ±100 ppm/℃)。
  • 封装通用:1206 封装兼顾功率与占板面积,适合多种电路布局。
  • 可靠性高:VISHAY 品牌与 CRCW 系列成熟工艺,产品通过常规机械与环境可靠性测试,适合长期量产使用。
  • 适应性强:工作温度范围宽,能在严苛环境(低温到高温)下工作。

四、典型应用场景

  • 电源与偏置网络:限流、分压、偏置设置。
  • 信号处理:滤波、电平划分和阻抗匹配。
  • 工业与消费电子:控制板、传感器接口、仪表仪器。
  • 通信设备与模块:用于通用阻值需求的分流或拉升。
  • 试验与样机开发:作为性价比高的标准阻值件使用。

五、使用与注意事项

  • 功率与散热:标称功率通常在环境温度 +70℃ 时为 250 mW,实际使用时应参考厂商的功率-温度降额曲线(高温环境下需降额使用)。
  • 焊接工艺:兼容常规回流焊流程,但建议遵照 VISHAY 的回流曲线与最大峰值温度限制,避免因过温影响长期可靠性。
  • 机械应力:贴装及后续清洗、塞压等工艺要避免对芯片施加过大机械应力,防止引发裂纹或接触不良。
  • 环境与存储:建议密封干燥存放,避免潮湿和化学污染;长期高温保存会影响电阻稳定性。
  • ESD:一般厚膜电阻对静电不敏感,但周边电路可能受 ESD 影响,PCB 设计与生产保护仍需到位。

六、质量与可靠性

VISHAY CRCW 系列产品通过严格的出厂测试与质量控制流程,常见可靠性试验包括温度循环、湿热、耐焊温、机械冲击与振动等。产品通常满足工业级可靠性要求,适合长期稳定运行的电子产品。采购时建议参考官方数据表以获取完整的可靠性和测试规范。

七、选型建议

  • 若需更高功率,可考虑更大封装(例如 2010/2512)或金属膜/合金薄膜方案;
  • 若需更低 TCR 或更高稳定性,可选择金属膜或薄膜精密电阻;
  • 对于空间受限且功率要求较低的场景,可在确保热设计的前提下选择更小封装。

总结:CRCW120647K0FKEA(VISHAY)以其 47 kΩ、±1% 精度、250 mW 功率和 1206 封装的均衡性能,适合绝大多数通用及工业应用场景,是一款性价比高且可靠的厚膜 SMD 电阻件。欲获取更详细的电气特性、焊接曲线及可靠性数据,请参阅 VISHAY 官方数据表。

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
