RC-02K1782FT 厚膜贴片电阻产品概述

RC-02K1782FT是风华电子(FH)推出的一款0402封装厚膜贴片电阻,专为高密度电路设计,具备精准阻值控制、宽温度适应性及稳定电气性能,广泛应用于消费电子、工业控制等领域。以下从核心参数、应用场景等维度详细介绍该产品。

一、产品基本信息

RC-02K1782FT的核心身份标识清晰:

  • 品牌:FH(风华电子),国内被动元器件领域知名厂商,产品通过RoHS、REACH等环保认证;
  • 封装:0402(英制尺寸,对应公制约1.0mm×0.5mm),属于超小型贴片封装,适配高密度PCB布线;
  • 电阻类型:厚膜电阻,采用丝网印刷+高温烧结工艺,兼具成本优势与性能稳定性;
  • 型号解析:“02”对应0402封装,“K1782”表示阻值17.8kΩ(17800Ω),“FT”为风华产品工艺与精度标识。

二、核心电气参数

该产品的电气性能符合工业级与消费类电子的常规需求,关键参数如下:

  1. 阻值与精度:标称阻值17.8kΩ,精度±1%,采用激光微调工艺实现,批量一致性误差控制在行业标准范围内;
  2. 额定功率:62.5mW(即1/16W),为0402封装贴片电阻的常规功率等级,需注意实际应用降额;
  3. 温度系数(TCR):±100ppm/℃,表示温度每变化1℃,阻值变化约1.78Ω(17.8kΩ×100×10⁻⁶),温度稳定性优于普通消费级电阻;
  4. 工作电压:约47V(由功率与阻值推导:P=U²/R → U=√(P×R)=√(62.5mW×17.8kΩ)≈47V),满足低压电路需求。

三、环境与可靠性

RC-02K1782FT的环境适应性覆盖工业级场景:

  • 工作温度范围:-55℃+155℃,可应对户外设备、高温车间等极端温度环境(普通消费级电阻通常为0℃70℃);
  • 存储条件:常温干燥环境(温度25℃±5℃、相对湿度≤60%),开封后建议12个月内使用,避免引脚氧化;
  • 耐候性:符合IEC 60068-2-67湿热试验标准,湿热环境下阻值漂移率≤0.5%(长期测试)。

四、典型应用领域

该电阻凭借小封装、宽温稳定的特点,适配多场景需求:

  1. 消费电子终端:智能手机、平板电脑的电源管理模块(分压、限流)、射频信号匹配网络;
  2. 工业自动化:PLC模拟量输入模块的信号调理电路、传感器(温度/压力传感器)的输出分压电路;
  3. 通信设备:路由器、交换机的射频前端阻抗匹配、电源滤波电路;
  4. 小型仪器:便携式万用表的电阻校准网络、信号发生器的衰减电路;
  5. 汽车电子辅助系统:车载信息娱乐系统的控制电路(温区155℃可覆盖部分车载高温区域)。

五、产品优势特点

与同类产品相比,RC-02K1782FT具备以下核心优势:

  1. 工艺成熟,成本可控:厚膜工艺替代薄膜工艺,在保证精度的前提下降低成本,适合批量应用;
  2. 小封装高密度:0402封装支持PCB板小型化,满足便携式设备(如智能手表)的布线需求;
  3. 宽温稳定可靠:±100ppm/℃的TCR与-55~155℃温区,极端温度下阻值偏差小,长期使用漂移率低;
  4. 品牌保障,供货稳定:风华电子的产能与质量管控成熟,可满足客户持续批量采购需求。

六、选型与使用注意事项

为确保产品性能与寿命,需注意以下事项:

  1. 功率降额:实际应用功率建议≤50mW(额定功率的80%),避免过热导致阻值漂移或损坏;
  2. 焊接规范:采用回流焊工艺,峰值温度≤245℃,焊接时间≤10秒(避免超过封装耐温极限);
  3. 静电防护:贴片电阻为静电敏感元件,操作时需佩戴防静电手环,使用防静电工作台;
  4. 精度匹配:若应用场景对精度要求高于±1%(如精密医疗仪器),需选择更高精度等级的电阻。

总结

RC-02K1782FT厚膜贴片电阻凭借精准的电气参数、宽温度适应性及小封装优势,成为消费电子、工业控制等领域的常用选型。风华电子的品牌保障进一步提升了其可靠性与性价比,适合对成本与性能平衡有要求的客户批量应用。

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.
