FRC0402F1401TS 厚膜贴片电阻产品概述

FRC0402F1401TS是富捷电子(FOJAN)推出的一款小体积厚膜贴片电阻,专为高密度、低功耗电路设计,符合0402封装的工业级性能要求,广泛应用于消费电子、工业控制、汽车电子等领域。

一、产品基本信息

该电阻隶属于富捷厚膜电阻系列,型号命名遵循行业常规逻辑:FRC为品牌系列标识,0402明确英制封装尺寸(对应公制约1.0mm×0.5mm),1401为阻值代码(前三位“140”为有效数字,第四位“1”表示10¹次方,即140×10¹=1400Ω=1.4kΩ),TS为精度及包装相关后缀(通常对应±1%精度及卷带编带包装)。产品采用厚膜陶瓷基片作为载体,通过丝网印刷电阻浆料、高温烧结成型等成熟工艺制备,兼具成本优势与性能稳定性。

二、核心电气参数

FRC0402F1401TS的电气参数覆盖常规低功耗电路的核心需求,关键指标如下:

  • 阻值与精度:1.4kΩ(1401代码),精度±1%,满足大多数工业级电路对阻值误差的要求,无需额外校准即可保证电路性能一致性;
  • 功率与电压:额定功率62.5mW,最大工作电压50V(需注意:实际工作功率需满足(P=V^2/R≤62.5mW),即最大安全工作电压约9.35V,50V为过压测试值,不可长期工作在该电压下);
  • 温度特性:温度系数(TC)±100ppm/℃,表示温度每变化1℃,阻值变化±100×10⁻⁶;工作温度范围-55℃~+155℃,覆盖工业级及部分汽车级环境温度需求;
  • 可靠性指标:耐焊接热(符合J-STD-020标准)、耐湿度(85℃/85%RH环境下1000小时阻值变化≤1%),保证长期使用稳定性。

三、物理与封装特性

  • 封装尺寸:0402英制封装(1.016mm×0.508mm),是当前贴片电阻中体积最小的常规封装之一,适合对PCB空间要求严格的小型化产品;
  • 基片与终端:采用氧化铝陶瓷基片(Al₂O₃),导热性与化学稳定性优异;终端为镀锡层(兼容无铅焊接),可焊性符合IEC 61010标准;
  • 包装方式:卷带编带包装(通常5000或10000只/盘),适配自动贴片机(SMT)生产,提高生产效率。

四、典型应用场景

基于小体积、宽温、低功耗的特性,FRC0402F1401TS适用于以下场景:

  1. 消费电子:智能手机、平板电脑的音频信号调理、电源滤波电路,或智能穿戴设备的传感器接口;
  2. 工业控制:小型PLC的输入输出接口、温度传感器(如PT100)的信号分压电路,或户外监控设备的低功耗模块;
  3. 汽车电子:车载仪表盘的背光控制、胎压监测系统(TPMS)的辅助电路(宽温范围已满足基础环境要求);
  4. 通信设备:小型基站、路由器的射频匹配电路,或光纤收发器的信号衰减电路;
  5. 医疗设备:便携式血糖仪、血压计的电源分压电路,宽温范围可适应不同使用环境。

五、关键性能优势

  1. 小体积高密度:0402封装比0603封装体积小约60%,可显著节省PCB空间,适合轻薄化产品设计;
  2. 性能稳定可靠:厚膜工艺保证阻值一致性,±100ppm/℃的温度系数在工业环境下阻值漂移可控,无需频繁校准;
  3. 宽温适应性:-55℃~+155℃的工作范围覆盖了从极寒到高温的多种应用场景,无需额外降额设计;
  4. 成本效益突出:厚膜电阻工艺成熟,批量生产成本低于薄膜电阻,适合中大规模应用;
  5. 焊接兼容性好:镀锡终端适配无铅回流焊,焊接良率高,适合SMT自动化生产。

六、使用注意事项

  1. 功率降额:实际工作功率不得超过62.5mW,若电路电压较高,需通过串联电阻或更换更高功率封装(如0603)实现降额;
  2. 焊接工艺:建议采用回流焊(温度曲线符合J-STD-020),避免手工焊接过热导致基片开裂或阻值漂移;
  3. 存储条件:常温干燥环境存储(温度25℃±5℃,湿度≤60%RH),开封后尽快使用,避免终端氧化影响可焊性;
  4. 静电防护:产品为静电敏感元件(ESD等级HBM 100V),操作时需佩戴静电手环,使用静电防护设备。

综上,FRC0402F1401TS是一款性价比突出的厚膜贴片电阻,兼具小体积、宽温、稳定可靠等特性,可满足多种低功耗、高密度电路的设计需求。

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.
