FRC0402F1742TS 贴片厚膜电阻产品概述

FRC0402F1742TS是富捷电子(FOJAN)推出的一款小型化高精度贴片厚膜电阻,专为高密度、低功耗电子电路设计,兼顾性能稳定性与成本优势。产品采用0402封装,核心参数匹配17.4kΩ阻值、±1%精度,广泛适用于消费电子、工业控制、汽车电子等领域的信号调理、分压滤波等场景。

一、产品基础属性与定位

FRC0402F1742TS属于厚膜贴片电阻,基于丝网印刷+高温烧结工艺制备,膜层结构稳定,耐环境性优于常规薄膜电阻的成本敏感型替代方案。其核心基础属性如下:

  • 封装规格:0402(英制,对应公制尺寸约1.0mm×0.5mm),体积仅为常规0603封装的1/4左右,适配高密度PCB布局;
  • 阻值标识:1742(三位有效数字+倍率,174×10²=17400Ω=17.4kΩ);
  • 品牌:FOJAN(富捷电子),国内专业电阻制造商,产品覆盖工业级与商业级应用。

二、关键性能参数详解

产品性能参数直接决定了应用场景的适配性,FRC0402F1742TS的核心参数如下:

2.1 阻值与精度

  • 标称阻值:17.4kΩ(17400Ω);
  • 精度等级:±1%(实际阻值范围17.226kΩ~17.574kΩ),满足常规信号调理电路的精度需求,无需额外校准;
  • 温度系数(TCR):±100ppm/℃,指温度每变化1℃,阻值变化±17.4kΩ×100×10⁻⁶=±1.74Ω。在工作温度范围(-55℃~155℃)内,最大阻值变化量为±174Ω(对应温度变化200℃),约为标称阻值的1%,与精度等级匹配。

2.2 功率与电压限制

  • 额定功率:62.5mW(0.0625W),为25℃环境温度下的最大连续功率;
  • 额定电压:50V,需注意功率与电压互锁:P=V²/R,50V时计算功率约143.7mW(超额定功率),实际使用需遵循“功率≤62.5mW”或“电压≤√(62.5mW×17.4kΩ)≈33.0V”的较严格限制。

2.3 环境适应性

  • 工作温度:-55℃+155℃,覆盖工业级(-40℃+85℃)与汽车级(-40℃~+125℃)常规温度区间;
  • 存储条件:-40℃~+85℃、湿度≤60%,长期存储无性能衰减。

三、封装与工艺优势

FRC0402F1742TS的0402封装与厚膜工艺带来显著优势:

  1. 小型化:0402封装体积小,可大幅减少PCB占用面积,适合便携式设备(如智能手环、蓝牙耳机)的高密度电路;
  2. 稳定性:厚膜烧结工艺形成致密膜层,抗机械应力、抗潮湿能力强,长期阻值漂移率≤0.5%/1000小时;
  3. 成本可控:相比薄膜电阻,原材料与制备成本更低,适合量产型消费电子与工业产品。

四、典型应用场景

结合参数特点,FRC0402F1742TS主要适用于以下场景:

  1. 便携式电子:智能手环心率传感器的分压电路、蓝牙耳机的信号滤波;
  2. 工业控制:小型PLC模拟量输入滤波、继电器驱动电路限流;
  3. 汽车电子:车载胎压监测、温度传感器的信号放大;
  4. 消费电子:智能家居插座的电源分压、摄像头过流检测;
  5. 通信设备:小型基站射频前端偏置电阻。

五、使用注意事项

为保证可靠性,需注意以下要点:

  1. 功率降额:环境温度超25℃时降额,100℃降额至50%(31.25mW),155℃降额至25%(15.625mW);
  2. 焊接工艺:回流焊温度峰值230℃~250℃,焊接时间≤10秒,避免热冲击;
  3. 存储搬运:防静电包装,存储湿度≤60%,防止静电击穿与受潮;
  4. 精度补偿:精密仪表场景需考虑温度系数,可通过补偿电路优化。

六、总结

FRC0402F1742TS作为高性价比小型化厚膜电阻,兼顾精度、功率与宽温适应性,适配多领域电子电路需求。其0402封装的小型化设计、±1%精度与±100ppm/℃温度系数,为高密度、低功耗电路提供可靠解决方案,是富捷电子针对中高端应用的代表性产品之一。

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.
