FRC0402F4872TS 贴片厚膜电阻产品概述

FRC0402F4872TS是FOJAN(富捷)推出的一款0402封装厚膜贴片电阻,针对小型化、低功耗电子设备设计,核心参数为48.7kΩ±1%阻值、62.5mW额定功率,兼顾精度与环境适应性,是各类紧凑电路中的通用选型。

一、产品核心身份与定位

该产品属于厚膜贴片电阻范畴,采用丝网印刷+高温烧结工艺制造,区别于薄膜电阻的高成本、碳膜电阻的低稳定性,平衡了性能与成本。其定位为低功耗高精度小型电阻,适配高密度PCB布局,可替代同类0402封装48.7kΩ阻值产品,覆盖消费电子、工业控制等多领域。

二、关键电气性能参数详解

1. 阻值与精度

阻值为48.7kΩ±1%,属于E96标准阻值系列(1%精度常用系列),精度满足多数电路的匹配需求——例如信号放大电路中,1%偏差可避免因阻值失配导致的增益误差;电源偏置电路中,可保证电压/电流输出稳定。

2. 功率与电流限制

额定功率62.5mW(0.0625W),是0402封装的常规低功耗等级。根据P=I²R计算,最大允许电流约1.13mA(I=√(62.5e-3/48.7e3)),实际应用中需留10%-20%余量,避免过热损坏。

3. 工作电压与绝缘性

最大工作电压50V(直流/交流通用),绝缘层可承受50V电压而不击穿,适合低电压电路(如3.3V、5V系统),若电路电压超过50V需串联或更换更高电压等级电阻。

4. 温度系数(TCR)

温度系数为**±100ppm/℃**,表示温度每变化1℃,阻值变化±0.01%。以25℃为基准,在工作温度范围(-55℃~+155℃)内,最大阻值漂移约±1.3%(155℃比25℃高130℃,130×0.01%=1.3%),该漂移量在工业、车载等宽温场景中可接受。

三、封装与物理特性

  • 封装规格:0402英制封装,对应公制尺寸1.0mm×0.5mm,厚度约0.3mm(典型值),适配主流回流焊、波峰焊工艺;
  • 电极设计:两端金属电极采用镍/锡镀层,焊接附着力强,可减少虚焊风险;
  • 尺寸优势:小型化设计支持高密度PCB布局,例如智能手机主板、智能穿戴设备等紧凑空间,可降低整机体积。

四、环境适应性与可靠性

  • 宽温工作范围:-55℃+155℃,覆盖工业级(-40℃+85℃)、部分车载级(-40℃+125℃)及消费电子(0℃+70℃)的温度需求,户外设备、车载传感器电路可稳定工作;
  • 厚膜工艺优势:厚膜电阻抗脉冲能力优于薄膜电阻,长期使用阻值漂移率低(老化后漂移<0.5%/1000小时);
  • 环保认证:符合RoHS、REACH标准,不含铅、镉等有害物质,适配全球市场。

五、典型应用场景

  1. 消费电子:智能手机电源管理电路、平板电脑信号滤波电路、智能手表传感器偏置电路;
  2. 小型家电:智能插座控制电路、蓝牙耳机充电盒状态指示电路;
  3. 工业控制:小型传感器接口电路、低功耗PLC输入输出电路;
  4. 医疗设备:便携式血糖仪信号调理电路、血压计压力传感器偏置电路;
  5. 汽车电子:车载小屏背光控制电路、胎压监测传感器电路(宽温适应)。

六、品牌与选型补充

  • 品牌背景:FOJAN(富捷)是国内专注被动元件的制造商,产品通过ISO9001、IATF16949(汽车级)认证,可靠性经市场验证;
  • 选型对比:若需更高功率(0.125W)可选0603封装(如FRC0603F4872TS);若需更高精度(0.1%)可选薄膜电阻(如FTC0402F4872TS);
  • 替代型号:同类产品可参考Yageo RC0402FR-0748.7KL、Samsung CL0402J4872GS,参数接近但品牌不同。

该产品以小型化、低功耗、宽温稳定为核心优势,兼顾成本与性能,是48.7kΩ阻值在紧凑电路中的可靠选型,可满足多领域电子设备的设计需求。

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
