  1. 消费电子:智能手机、平板电脑、智能穿戴设备的信号调理电路(如滤波、分压)、电源管理模块(如限流);
  2. 汽车电子:车载中控、仪表盘、传感器信号放大电路(如胎压监测、温度传感器),适配汽车级工作温度范围;
  3. 工业控制:PLC模块、传感器接口电路、小型仪器仪表的电压/电流采样;
  4. 通信设备:路由器、交换机的射频前端滤波、偏置电路,适配高密度PCB布局。

二、基础参数与性能特性

该型号的关键参数与性能如下,符合工业级电子元器件的基本要求:

参数项 规格值 说明 电阻类型 厚膜贴片电阻 氧化铝陶瓷基底+厚膜电阻浆料 标称阻值 20kΩ(代码:2002) 激光微调保证批次一致性 精度等级 ±1% 工业通用精度,覆盖多数场景 额定功率 62.5mW(1/16W) 0402封装的典型额定功率 最大工作电压 50V 绝对最大额定值,需降额使用 温度系数(TCR) ±100ppm/℃ 每升高1℃,阻值变化±2Ω(20kΩ×100ppm) 工作温度范围 -55℃ ~ +155℃ 覆盖工业级与汽车级温度需求

性能优势:厚膜工艺赋予其良好的抗冲击性、耐温稳定性,激光微调技术确保阻值精度一致,适合批量生产的一致性要求。

三、封装与物理尺寸

该型号采用0402英制贴片封装(对应公制1005封装),是当前小型化电子设备中最常用的贴片封装之一,物理尺寸符合行业标准:

  • 长度:1.0±0.1mm
  • 宽度:0.5±0.1mm
  • 厚度:0.3±0.1mm
  • 引脚端宽度:0.2±0.1mm

封装特点:引脚间距紧凑(约0.4mm),适合高密度PCB设计,可兼容回流焊、波峰焊等标准贴片工艺(焊接温度需控制在260℃以下,持续时间不超过10秒)。

四、可靠性与环境适应性

华新科WR04X2002FTL通过多项可靠性测试,适配严苛环境:

  1. 环境试验:符合IEC 60068标准,通过温度循环(-55℃155℃,1000次循环)、湿热试验(40℃/95%RH,1000小时)、振动试验(102000Hz,加速度2g);
  2. 电气可靠性:额定功率下长期工作阻值变化率≤0.5%,过负载试验(2倍额定功率,1000小时)阻值变化≤1%;
  3. 汽车级认证:若应用于汽车电子,可提供AEC-Q200认证版本(需确认具体型号后缀),满足汽车级可靠性要求。

五、品牌与品质保障

华新科(Walsin)作为全球领先的被动元件供应商,具备以下优势:

  1. 工艺技术:拥有成熟的厚膜电阻浆料配方与激光微调技术,阻值一致性控制在行业前列;
  2. 认证资质:通过ISO 9001质量管理体系、IATF 16949汽车电子质量管理体系、RoHS/REACH环保认证;
  3. 供货能力:全球布局生产基地,批量供货稳定,交期可控(标准交期2~4周)。

六、选型与使用注意事项

  1. 选型参考:同系列可选择其他阻值(如1kΩ、10kΩ、47kΩ),若需更高精度(±0.1%)或更低温漂(±50ppm/℃),可考虑华新科WR系列高端款;
  2. 使用降额:工作温度超过85℃时,需按温度系数降额功率(如125℃时功率降额至50%);
  3. 存储要求:未开封产品存储于常温干燥环境(温度1535℃,湿度4060%RH),开封后建议12个月内使用完毕。

该型号凭借小型化、高可靠性及成本优势,成为众多电子设备的首选贴片电阻之一,可满足多数通用电路的性能需求。

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
