CRCW020133R0FNED 产品概述

一、产品简介

CRCW020133R0FNED 为 VISHAY(威世)出品的贴片厚膜电阻,0201 超小封装,阻值 33Ω,精度 ±1%,额定功率 50 mW。该器件基于成熟的厚膜工艺制造,兼具体积小、成本低、适用于高密度表贴电路板的优点,适合在空间受限的消费电子、便携设备和高密度互连应用中作分压、限流、阻尼或匹配元件使用。

二、主要技术参数

  • 电阻类型:厚膜电阻
  • 阻值:33 Ω
  • 精度:±1%(F)
  • 额定功率:50 mW
  • 工作电压:最大 30 V
  • 温度系数(TCR):±200 ppm/℃
  • 工作温度范围:-55 ℃ ~ +155 ℃
  • 封装:0201(超小型片式)
  • 品牌:VISHAY(威世)

三、结构与封装

0201 封装为常见的超小型片式封装,外形尺寸约属 0.6 mm × 0.3 mm 量级(具体尺寸以厂商资料为准)。厚膜电阻由基板、厚膜阻性膜层、保护釉以及电极端接组成,端接表面通常进行银或镍/金处理以保证良好的可焊性与可靠性。超小体积便于在高密度 PCB 布局中节省空间,但对贴装工艺及操作要求更高。

四、性能特点

  • 小体积高密度:0201 封装适合空间受限设计与微型化产品。
  • 良好的一致性与稳定性:±1% 精度满足较高容差要求的通用电路应用。
  • 典型厚膜特性:成本效益高,适合大批量生产;TCR 相对较高(±200 ppm/℃),需考虑温漂影响。
  • 耐温范围宽:-55 ℃ 至 +155 ℃,适用于工业级环境。
  • 适配常规 SMT 工艺:兼容回流焊装配流程,便于自动化贴装。

五、典型应用场景

  • 移动终端、可穿戴设备等对 PCB 面积要求高的便携产品;
  • 信号偏置、限流、阻尼与阻抗匹配电路;
  • 消费电子、物联网节点中的分压与小电流测量回路;
  • 高密度互连板(HDI)与多层板中的通用受控阻值元件。

六、使用建议与注意事项

  • 功率与降额:标称 50 mW 为额定功率,在不同环境温度下需按厂商降额曲线处理;高温环境中元件可承受功率会降低,设计时请留有余量。
  • 最大工作电压 30 V:超过该电压可能引起击穿或稳定性问题,实际应用中应确保工作电压低于此值并考虑过压保护。
  • 温漂与精度管理:TCR 为 ±200 ppm/℃,在要求高温稳定性的场合应评估温漂对电路性能的影响,必要时采用温度补偿或更低 TCR 的元件。
  • 贴装与回流焊:0201 尺寸极小,贴装需使用精密贴片机器和合适的吸嘴;建议采用厂家推荐的回流温度曲线(兼容无铅回流工艺),避免多次重复回流和过高峰值温度。
  • 存储与操作:避免长时间潮湿环境暴露,裸露产品或已拆封卷带应按推荐条件存储并在规定时间内使用;操作时注意防止机械损伤并使用防静电措施。

七、可靠性与选型要点

选择 CRCW020133R0FNED 时应关注以下要点:所需阻值与精度是否匹配(±1%),工作电压是否低于 30 V,环境温度是否在 -55 ℃ ~ +155 ℃ 范围内,以及电路对温漂和噪声的容忍度。对于对温度稳定性或低噪声有严格要求的设计,可考虑薄膜或金属膜电阻作为替代;对于成本敏感且要求高密度封装的场合,CRCW0201 厚膜产品为性价比优选。

如需最终产品数据和封装尺寸、回流焊曲线、典型性能曲线与可靠性试验报告,请参考 VISHAY 官方数据手册或联系供应商获取完整技术资料,以保证在具体应用中满足所有工艺与可靠性要求。

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
