FRC0402F4700TS厚膜贴片电阻产品概述

一、产品定位与典型应用场景

FRC0402F4700TS是富捷电子(FOJAN)推出的0402封装厚膜贴片电阻,专为小型化、高密度PCB设计的电路场景打造。其核心优势在于小体积下兼顾基础精度与环境适应性,广泛适配以下领域:

  • 消费电子:智能手机、智能手表等可穿戴设备的信号分压、限流电路;
  • 小型家电:智能插座、迷你加湿器等控制板的反馈电路;
  • 工业控制:小型传感器模块、微型MCU周边的辅助电路;
  • 通信设备:低功耗蓝牙模块、WiFi模块的阻抗匹配电路。

该电阻体积仅1.0mm×0.5mm,能有效节省PCB布局空间,满足当前电子设备“轻薄化”的设计趋势。

二、核心电气参数详解

作为厚膜贴片电阻的典型代表,FRC0402F4700TS的电气参数精准覆盖基础应用需求,关键参数如下:

2.1 阻值与精度

标称阻值470Ω(编码“4700”),精度等级±1%,满足大部分常规电路的阻值控制要求(如分压电路的电压精度、限流电路的电流稳定性)。对于精度要求更高的场景,可通过多电阻并联/串联校准,但基础应用无需额外操作。

2.2 功率与电压

  • 额定功率:62.5mW(0.0625W),为0402封装厚膜电阻的常规功率等级;
  • 工作电压:最大50V,需注意实际使用中需结合功率降额:根据公式(P=V^2/R),实际最大工作电压应≤(\sqrt{62.5mW×470Ω}≈5.42V),避免过功率损坏。

2.3 温度特性

温度系数(TCR)±100ppm/℃,即温度每变化1℃,阻值变化±0.01%;温度变化100℃时,阻值变化±1%,符合一般工业级电路的温度稳定性要求(如户外小型设备的环境波动场景)。

2.4 工作温度范围

-55℃~+155℃,覆盖低温环境(如北方户外设备)与高温环境(如小型家电内部散热区域),无需额外散热设计即可稳定工作。

三、封装与物理特性

FRC0402F4700TS采用0402封装(公制1005),具体物理参数如下:

  • 尺寸:长度1.0±0.2mm,宽度0.5±0.2mm,高度0.35±0.1mm;
  • 电极结构:厚膜银电极+镍层+锡层(无铅Sn/Ag/Cu为主),兼容回流焊、波峰焊工艺;
  • 包装:卷装(常规10k/盘或5k/盘),适配自动化贴装设备,生产效率高。

厚膜电阻的膜层采用高温烧结工艺,相比薄膜电阻成本更低,相比碳膜电阻稳定性更好,是平衡成本与性能的优选方案。

四、可靠性与环境适应性

FRC0402F4700TS通过多项可靠性测试,满足工业级应用要求:

  • 耐湿测试:符合IEC 60068-2-60(湿热循环),40℃/93%RH环境下1000小时阻值变化≤±1%;
  • 耐脉冲测试:承受1000次10V/100μs脉冲后,阻值变化≤±0.5%;
  • 环保要求:符合RoHS 2.0、REACH法规,无铅无卤,适配出口产品需求。

此外,厚膜电阻的膜层具有较强的抗机械应力能力,在PCB弯曲(如可折叠设备)场景下仍能保持稳定性能。

五、品牌与品质保障

FRC0402F4700TS由富捷电子(FOJAN) 生产,该品牌是国内专注于被动元器件的知名厂商,产品覆盖电阻、电容、电感等全系列,广泛应用于华为、小米、美的等主流客户的供应链中。

富捷电子的品质保障体系包括:

  • 全流程自动化生产:从膜层印刷到封装测试均采用自动化设备,减少人为误差;
  • 出厂全检:每批次产品均进行阻值、功率、温漂等关键参数检测,不合格率≤0.1%;
  • 售后支持:提供技术咨询与样品支持,针对客户特殊需求可定制参数(如精度、TCR)。

总结

FRC0402F4700TS是一款高性价比的0402封装厚膜贴片电阻,兼顾小体积、基础精度与环境适应性,适合各类小型化电子设备的常规电路设计,是电子工程师平衡成本与性能的可靠选择。

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.
