WR06X2401FTL 片式厚膜电阻产品概述

WR06X2401FTL是华新科(Walsin)推出的0603封装厚膜片式电阻,针对小型化、宽温区应用场景优化设计,核心参数覆盖通用精密级电阻的典型需求,广泛适配消费电子、工业控制等领域的电路设计。

一、产品基本定位与核心参数

该电阻属于厚膜电阻系列,采用0603(英制规格,对应公制1608)小型封装,核心参数明确且稳定:

  • 阻值:2.4kΩ(阻值代码2401,即24×10²=2400Ω);
  • 精度:±1%(通用精密级,满足多数电路的匹配与信号误差控制需求);
  • 额定功率:100mW(1/10W,低功耗设计适配小型设备的功率约束);
  • 最大工作电压:75V(电压上限,实际使用需同时满足功率限制);
  • 温度系数(TCR):±100ppm/℃(阻值随温度变化的稳定性指标);
  • 工作温度范围:-55℃~+155℃(覆盖工业级及部分高温场景的环境要求)。

二、关键性能指标详解

1. 阻值精度与电路适配性

±1%的精度属于市场主流精密级水平,可有效避免分压、限流电路中的信号偏移。例如在模拟信号调理电路中,该精度能保证输出电压误差控制在0.5%以内(结合电路设计余量),满足大多数消费电子和工业设备的基本精度要求,无需额外增加校准成本。

2. 功率与电压的约束关系

额定功率100mW是电阻允许的最大耗散功率,最大工作电压75V是电压上限,实际使用需同时满足两个条件:

  • 功率计算:( P = \frac{V^2}{R} ),当电压达到75V时,功率仅为( 75^2/2400 ≈ 2.34mW ),远低于100mW,因此实际限制主要来自电压上限;
  • 降额建议:为延长寿命,实际功率建议控制在70mW以下(即额定功率的70%降额),可将长期阻值漂移控制在0.3%以内。

3. 温度系数与宽温适应性

±100ppm/℃的TCR表示温度每变化1℃,阻值变化±0.01%。例如从室温(25℃)到高温极限(155℃),温度变化130℃,阻值变化约±1.3%,叠加±1%的精度后,总阻值误差约±2.3%,可满足宽温区(如车载辅助系统、工业高温模块)的稳定运行需求。

三、封装与工艺特点

1. 0603封装的空间优势

0603封装尺寸为1.6mm×0.8mm,厚度约0.4mm,是小型化电路设计的常用封装之一:

  • 适配高密度PCB布局,适合智能手机、穿戴设备等对空间要求严格的产品;
  • 兼容回流焊、波峰焊工艺,焊接效率高,适合批量生产。

2. 厚膜工艺的可靠性保障

采用厚膜丝网印刷+高温烧结工艺,相比薄膜电阻成本更低,且具有以下优势:

  • 终端采用银/镍/锡三层电极,耐焊接热冲击(可通过260℃回流焊3次测试,无开裂或阻值漂移);
  • 电阻膜层稳定性好,长期工作后阻值漂移小(额定功率下1000h阻值变化≤0.5%)。

四、典型应用场景

WR06X2401FTL的参数特点使其适用于以下场景:

  • 消费电子:智能手机、平板的电源分压电路、音频信号调理电路;
  • 工业控制:小型PLC、传感器模块的信号放大偏置电阻;
  • 穿戴设备:智能手表、手环的低功耗限流电阻;
  • 汽车电子:车载显示屏背光电路、辅助传感器信号电路(-55~155℃温区适配);
  • 通信模块:WiFi、蓝牙模块的偏置电阻(宽温区保证信号稳定传输)。

五、使用注意事项

  1. 选型确认:需核对封装(0603)、阻值(2.4kΩ/2401)、精度(±1%)是否与电路需求匹配,避免参数不兼容导致的性能问题;
  2. 焊接工艺:遵循华新科推荐的回流焊曲线(峰值温度245±5℃,时间≤10s),避免温度过高导致电阻膜层损坏;
  3. 存储条件:存储于常温干燥环境(1535℃,湿度4060%RH),开封后1个月内使用完毕,避免受潮影响焊接性;
  4. 环境防护:若应用于高湿、高盐雾环境,建议采用 conformal coating( conformal coating)防护,避免水汽侵蚀电阻膜层。

WR06X2401FTL凭借紧凑的尺寸、稳定的性能和宽温适应性,成为华新科厚膜电阻系列中的经典型号,适用于对成本和性能平衡要求较高的中小批量及量产项目。

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.
