CRWC0402165KFKED 贴片厚膜电阻产品概述

CRWC0402165KFKED是VISHAY(威世)推出的0402封装厚膜贴片电阻,属于CRCW系列通用型贴片电阻产品,主打小型化、高可靠性与精准阻值,适用于对空间紧凑性和电气性能稳定性要求较高的电子电路设计。

一、产品基本定位与系列归属

该电阻采用厚膜工艺制造,结合0402(英制)/1005(公制)小封装设计,兼具成本优势与性能稳定性,是VISHAY针对消费电子、工业控制、通信等领域开发的成熟产品。核心定位为通用型精准贴片电阻,可替代同参数其他品牌产品,满足大多数小型化电路的阻值与功率需求。

二、核心电气参数详解

1. 阻值与精度

标称阻值为165kΩ,精度等级**±1%**,优于普通±5%精度电阻,适合信号分压、运算放大器反馈网络、滤波电路等需准确阻值匹配的场景,可减少电路参数误差累积。

2. 功率与电压额定值

  • 额定功率:63mW(接近0402封装典型功率1/16W≈62.5mW),满足低功耗电路需求;
  • 工作电压:50V(直流/低频),实际功耗约束为P=V²/R,50V下功耗约15mW(远低于额定功率),电压额定值主要限制过压损坏(如瞬间浪涌)。

3. 温度系数(TCR)

温度系数**±100ppm/℃**,表示温度每变化1℃,阻值变化约0.01%。在工作温度范围(-55℃~+155℃)内,最大阻值变化量为2.1%,结合±1%精度,极端温度下总阻值偏差±3.1%,满足宽温环境稳定性要求。

三、物理与环境适应性

1. 封装规格

采用0402封装(尺寸≈1.0mm×0.5mm),是贴片电阻最小规格之一,适合高密度PCB布局(如智能手机主板、可穿戴设备模块),有效节省电路空间。

2. 工作温度范围

宽温范围**-55℃+155℃**,覆盖工业级(-40℃+85℃)、汽车级(部分场景)及航空航天应用温度需求,可在极端环境下稳定工作。

3. 厚膜工艺优势

厚膜工艺通过丝网印刷、烧结制造,相比薄膜电阻成本更低,相比碳膜电阻稳定性更好,抗过载能力适中,适合长期稳定运行。

四、典型应用场景

1. 消费电子领域

  • 智能手机/平板射频前端(信号滤波、分压网络);
  • 可穿戴设备传感器接口(心率、加速度传感器信号调理);
  • 便携式音频设备(音量控制、滤波电路)。

2. 工业控制领域

  • 小型PLC输入输出接口;
  • 工业传感器模块(温度、压力传感器信号放大);
  • 小型工业电源反馈调节电路。

3. 通信设备领域

  • 小型基站/路由器射频电路(滤波器、匹配网络);
  • 光纤收发器信号调理;
  • 通信模块电源管理(电压分压检测)。

4. 汽车电子潜在应用

  • 汽车仪表盘背光调节;
  • 车载胎压监测传感器接口(需确认汽车级认证,适配宽温特性)。

五、品牌与可靠性说明

VISHAY作为全球被动元件龙头,CRCW系列电阻经严格可靠性测试(高温存储、温度循环、湿度、机械振动等),符合IEC、JEDEC标准,长期性能稳定。无铅无卤,符合RoHS环保要求,适配绿色电子产品设计。

总结:CRWC0402165KFKED是一款小封装、精准度、宽温适应性的厚膜贴片电阻,兼具成本优势与可靠性,广泛适用于消费电子、工业、通信等领域的小型化电路设计。

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
