CRCW04021K30FKED 产品概述

一、产品简介

CRCW04021K30FKED 是 VISHAY(威世)出品的一款 0402 封装厚膜贴片电阻,标称阻值 1.3 kΩ,精度 ±1%,温度系数(TCR)±100 ppm/℃,额定功率 62.5 mW(通常指 +70℃ 状态下),最大工作电压 50 V,工作温度范围为 −55℃ 到 +155℃。0402 封装尺寸约 1.0 mm × 0.5 mm,适合高密度 SMT 布局与轻薄化设计需求。

二、主要电气参数

  • 阻值:1.3 kΩ
  • 精度:±1%(0.5% 或更高精度需另行选型)
  • 温度系数:±100 ppm/℃,适用于对温漂有一定要求但不极端的应用场合
  • 额定功率:62.5 mW(参考值,随环境温度需降额使用)
  • 最大工作电压:50 V
  • 环境温度范围:−55℃ 至 +155℃
  • 电阻类型:厚膜(成本和批量稳定性优于薄膜在某些应用)

三、性能与可靠性要点

厚膜工艺使该系列电阻具有良好的通用性和成本效益,±1% 精度配合 ±100 ppm/℃ 的温漂,能在多数工业与消费类电子的信号处理、分压与偏置电路中保持足够的稳定性。工作温度范围宽(−55℃~+155℃),适应工业级环境。需要注意的是,0402 的体积与热容量较小,长时间在高功耗或高环境温度下工作时应按照制造商的功率降额曲线进行设计,以避免可靠性下降。

四、典型应用场景

  • 高频微控制器与模拟电路的分压、偏置与限流元件
  • 手持设备、便携终端及 IoT 芯片周边的常规阻值需求
  • 信号调节、采样电路与滤波网络中的阻性元件
  • 工业控制与仪表中密集贴装场合的通用替代件

五、封装、焊接与使用建议

  • 封装与包装:0402 尺寸,常见为卷带(tape-and-reel)供料,便于自动贴装。
  • 焊接:兼容无铅回流工艺,推荐遵循元件制造商的回流曲线与峰值温度限制。
  • 散热与降额:额定功率通常在 +70℃ 时有效,随环境温度升高应线性降额至最高工作温度。设计时应留有功率裕量;若需要在高温或高功耗场合使用,建议选用更大封装或更高额定功率的型号。
  • 机械与清洗:0402 体积小,避免在贴装后施加较大机械应力;波峰焊或手工焊接需控制热冲击并避免过度机械挤压。

六、选型与采购建议

在选型时除查看阻值与精度外,应重点关注温度系数、额定功率及实际工作环境温度,以保证长期稳定性。若对温漂、长期漂移或噪声有更苛刻要求,可考虑薄膜或金属膜精密电阻;如需汽车级或特殊认证,请向厂商确认是否满足 AEC 或其他规范。采购时建议索取最新 Datasheet 与样片进行实装验证,确保回流、清洗工艺与 PCB 布局满足实际可靠性需求。

总结:CRCW04021K30FKED 以其小型化、±1% 精度和适中的温漂特性,适合大多数对体积与成本敏感的通用电子设计;在高温、高功耗或精密测量场合,需进行降额或选用更高等级产品。若需完整电气与热特性曲线,请参考 VISHAY 官方 Datasheet。

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
