CRCW0603220RFKEAHP 厚膜贴片电阻产品概述

CRCW0603220RFKEAHP是VISHAY(威世)推出的一款工业级厚膜贴片电阻,采用0603(英制封装,对应公制1608)小型化设计,凭借稳定的电气性能、宽温适应性及高可靠性,广泛覆盖消费电子、工业控制、汽车电子等领域。以下是该产品的核心概述:

一、产品基本属性与命名解析

该电阻属于VISHAY经典CRCW厚膜贴片电阻系列,命名规则清晰映射核心参数:

  • CRCW:VISHAY厚膜贴片电阻系列标识;
  • 0603:英制封装尺寸(长0.06英寸×宽0.03英寸,约1.6mm×0.8mm);
  • 220:标称阻值220Ω;
  • R:阻值小数点占位符(220Ω无小数点,故用R标识);
  • F:精度等级±1%;
  • KEAHP:附加参数代码(含温度系数、功率等级等定制化信息)。

产品采用厚膜丝网印刷工艺制造,将电阻浆料烧结于氧化铝陶瓷基底,兼具成本优势与性能稳定性。

二、关键电气参数详解

核心参数满足多数中低端至工业级电路需求,具体如下:

  1. 阻值与精度:标称220Ω,精度±1%(25℃下阻值偏差≤±2.2Ω),可满足电路参数一致性要求;
  2. 功率等级:额定功率333mW(约1/3W),为环境温度25℃、无散热条件下的最大允许功率;
  3. 工作电压:最大允许电压75V(直流/交流峰值),需注意:实际工作需结合功率降额曲线,避免长期过压导致电阻老化;
  4. 温度系数(TCR):±100ppm/℃,即温度每变化1℃,阻值变化±220×10⁻⁶=±0.022Ω;全温宽内(-55℃~+155℃)阻值总变化约±4.62Ω,符合工业级温稳要求。

三、环境适应性与可靠性

产品环境参数覆盖工业级场景:

  • 工作温度范围:-55℃~+155℃,可耐受极端高低温,适用于汽车发动机舱、户外工业设备等 harsh 环境;
  • 耐湿性能:厚膜工艺+陶瓷基底,抵抗湿度变化(符合IEC 60068-2-67标准);
  • 机械强度:0603封装陶瓷基底抗振动、冲击,满足汽车电子振动测试(如MIL-STD-202G)。

四、典型应用场景

基于参数特性,适用于以下场景:

  1. 消费电子:手机、平板的音频滤波、电源反馈电路;
  2. 工业控制:PLC I/O接口电阻、传感器信号调理电路;
  3. 汽车电子:胎压监测(TPMS)信号放大、辅助驾驶传感器接口;
  4. 通信设备:基站射频匹配电阻、光模块偏置电路;
  5. 电源管理:DC-DC电压采样、线性电源限流电阻。

五、选型与使用注意事项

确保可靠性需注意:

  1. 功率降额:环境温度超70℃时,按VISHAY降额曲线降功率(如125℃时降额至50%);
  2. 焊接工艺:推荐回流焊(符合J-STD-001),避免手工焊接局部过热;
  3. 静电防护:抗静电能力(HBM≥2kV),但需按ESD规范操作;
  4. 参数匹配:确认电路最大功率、电压在额定范围内,避免过负荷。

六、品牌与质量优势

VISHAY CRCW系列具备:

  • 一致性:批量阻值、温系偏差小,降低调试难度;
  • 可靠性:通过AEC-Q200汽车级、IEC 61000电磁兼容认证;
  • 供应稳定:大规模量产,供货周期短,适合量产项目。

综上,CRCW0603220RFKEAHP是性价比高、可靠性强的厚膜贴片电阻,可满足多数中高端电路设计需求。

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
