华新科WR06X2493FTL厚膜固定电阻器产品概述

一、产品基本定位与核心身份

华新科WR06X2493FTL是一款小型化表面贴装厚膜固定电阻器,隶属于华新科(Walsin)通用电阻产品线。该型号针对“体积紧凑、精度适中、宽温适应性”的电路设计需求开发,采用0603封装(英制,对应公制1608),是消费电子、工业控制、通信设备等领域的常用基础元器件,平衡了性能与成本,适配高密度PCB布局场景。

二、关键电气性能参数详解

该型号的核心电气参数围绕“精度、功率、温度稳定性”三个维度设计,具体如下:

  • 阻值与精度:标称阻值249kΩ(阻值代码2493,即249×10³Ω),精度±1%,符合E96电阻系列的精度规范,满足多数电路对阻值误差的控制要求(如信号分压、基准电压调节等场景);
  • 额定功率:100mW(1/10W),为0603封装厚膜电阻的典型额定功率,需注意实际功耗需结合使用环境降额;
  • 工作电压:75V(最大允许工作电压),直接限制了电路中的最大施加电压,避免因过压导致电阻击穿;
  • 温度系数(TCR):±100ppm/℃,表示温度每变化1℃,阻值变化±0.01%,例如100℃温差下阻值漂移±1%,属于厚膜电阻中中等偏优的温度稳定性水平,适合对温漂敏感的简单信号电路。

三、物理封装与机械特性

WR06X2493FTL采用0603表面贴装封装,物理尺寸为1.6mm(长)×0.8mm(宽)×0.45mm(典型厚度),适配自动化贴装生产线,可实现高密度PCB布局。其制作工艺为“陶瓷基板+厚膜电阻浆料印刷+烧结调阻+环氧树脂封装”,机械强度优于多数薄膜电阻,抗振动、抗冲击性能可满足一般工业场景需求(如小型设备的运输振动测试)。

四、环境适应性与可靠性表现

该型号的环境适应性覆盖宽温范围与恶劣工况:

  • 工作温度:-55℃+155℃,覆盖工业级(-40+85℃)、汽车辅助级(部分-55~+125℃)的温度要求,可在高温高湿、低温寒冷环境下稳定工作;
  • 可靠性测试:华新科对该产品进行了严格的可靠性验证,包括高温高湿(85℃/85%RH,1000小时)、温度循环(-55+155℃,1000次)、振动(102000Hz,1g)等测试,阻值变化率、接触电阻均符合IEC 61000等国际标准,长期使用稳定性有保障。

五、典型应用场景梳理

结合参数特性,WR06X2493FTL的典型应用场景包括:

  1. 消费电子:智能手机、平板电脑的电源管理电路(如分压反馈)、音频信号调理电路;
  2. 工业控制:小型PLC、传感器接口电路(如热敏电阻信号放大的偏置电阻);
  3. 通信设备:路由器、小型基站的射频前端辅助电路(0603封装适配高密度贴装);
  4. 便携式医疗设备:血糖仪、小型监护仪的低功耗电路(体积紧凑+精度适中);
  5. 汽车电子:仪表盘背光调节、车身控制模块的辅助信号电路(宽温范围适配车载环境)。

六、选型与使用注意事项

为确保电路可靠性,使用时需注意以下要点:

  • 功率降额:高温环境(>125℃)下建议工作功率不超过额定功率的50%(即50mW),常温下可放宽至80%(80mW),避免过热导致阻值漂移;
  • 电压限制:实际工作电压不得超过75V,同时需验证V≤√(P×R)(理论值≈158V),以厂家标称的75V为最终限制;
  • 贴装工艺:回流焊峰值温度需控制在245±5℃,焊接时间30~60秒,避免因温度过高损坏陶瓷基板;
  • 储存条件:未使用的电阻需储存在温度-20+30℃、湿度30%70%的环境中,开封后建议1年内使用完毕,避免受潮影响性能。

该型号凭借“小体积、高性价比、宽温适配”的特点,成为众多中小功率电路设计的优选元件,可有效降低PCB布局难度,提升产品集成度。

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.
