RC-02K1333FT 厚膜贴片电阻产品概述

RC-02K1333FT是风华FH品牌推出的通用型厚膜贴片电阻,采用0402小型化封装,针对工业控制、消费电子等领域的小信号电路设计,兼具成本可控与稳定性优势,可满足多数常规应用场景的性能需求。

一、产品核心身份标识

RC-02K1333FT的型号编码隐含核心属性:

  • 品牌:风华FH(国内被动元件龙头,厚膜电阻技术积累深厚,产品覆盖多封装/阻值系列);
  • 类型:厚膜贴片电阻(通过丝网印刷、烧结工艺制备,氧化铝陶瓷基底兼具绝缘性与导热性);
  • 型号解析:RC代表厚膜贴片电阻,02K对应0402封装(英制0.04″×0.02″/公制1.0mm×0.5mm),1333表示阻值133kΩ(133×10³Ω),FT关联精度、温度系数等特性。

二、关键电气性能参数

该电阻电气性能针对常规场景优化,核心指标如下:

  • 阻值:133kΩ(E96标准阻值系列,适配1%精度要求);
  • 精度:±1%(满足信号调理、分压电路的精度需求,优于±5%通用级电阻);
  • 额定功率:62.5mW(1/16W),契合0402封装功率密度上限,小信号电路无需降额;
  • 温度系数(TCR):±100ppm/℃(温度每变1℃,阻值变±0.01%;100℃温差下阻值变化≤±1.33kΩ,满足工业环境稳定性);
  • 最大工作电压:约91V(由P=V²/R推算,实际需避免超压击穿)。

三、物理封装与机械特性

0402封装具备小型化、高密度布局优势:

  • 封装材料:氧化铝陶瓷基片(导热系数≥15W/(m·K),快速散发电功率热量);
  • 端电极:银钯合金(焊接性优异,兼容Sn-Pb/无铅焊料,耐老化);
  • 机械强度:符合IPC-610标准,1.5m跌落测试无失效,可承受PCB组装应力;
  • 焊盘要求:建议尺寸1.0mm×0.6mm(IPC-7351规范),避免桥接/虚焊。

四、环境适应性与可靠性

覆盖工业级温度范围,可靠性符合行业标准:

  • 工作温度:-55℃~+155℃(满足汽车电子、工业控制极端温度需求,如车载传感器、户外PLC);
  • 湿热性能:40℃/93%RH、1000小时测试,阻值变化≤±1%;
  • 寿命特性:125℃额定功率下工作1000小时,阻值漂移≤±1%;
  • 抗硫化能力:端电极抗硫化配方,避免高硫环境下电极失效(适配部分工业场景)。

五、典型应用场景

因尺寸小、性能稳定,广泛应用于:

  • 消费电子:智能手机、平板的信号滤波、偏置电路;
  • 工业控制:PLC模拟量输入输出模块、传感器信号放大电路;
  • 汽车电子:车载信息娱乐系统电源分压、胎压监测接口电路;
  • 通信设备:路由器、交换机的信号衰减、阻抗匹配电路;
  • 小型医疗仪器:血糖仪、血氧仪的信号检测电路(基础性能满足常规需求)。

六、选型与使用注意事项

确保性能稳定需注意:

  • 选型匹配:功率需求>62.5mW选0603封装(1/10W);精度需求>±1%选薄膜电阻;
  • 焊接规范:回流焊峰值230240℃(1020秒),波峰焊240250℃(35秒),避免高温漂移;
  • 存储要求:未焊接电阻存于25±5℃、湿度≤60%RH干燥环境,防电极氧化;
  • 防静电:遵循IEC 61340-5-1,静电敏感度HBM 2级(±2000V),组装需防静电操作。

以上内容涵盖产品核心特性与应用要点,可作为选型、设计参考依据。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

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
