RC-02K2673FT 厚膜贴片电阻产品概述

RC-02K2673FT是风华电子(FH)推出的一款小型化厚膜贴片电阻,以0402(1005公制)封装为核心,聚焦常规精度、低功耗场景的电路设计需求,兼具宽温适应性与成本优势,广泛适配消费电子、工业控制、汽车电子等领域的基础电阻应用。

一、产品基本属性与定位

该电阻属于厚膜工艺贴片电阻,定位为通用型常规精度组件:

  • 品牌:风华电子(FH),国内电子元器件行业头部厂商,厚膜电阻技术积累超过30年;
  • 封装:0402(英制)/1005(公制),尺寸为1.0mm×0.5mm,是当前小型化电子设备的主流封装之一;
  • 核心参数:阻值267kΩ(E96系列标准阻值)、精度±1%、额定功率1/16W(62.5mW)、温度系数±100ppm/℃、工作温度-55℃~+155℃。

二、核心性能参数详解

1. 阻值与精度

RC-02K2673FT采用E96系列标准阻值267kΩ,精度为±1%,满足大多数电路的误差要求:

  • 适用于分压电路(如电压采样)、限流电路(如LED驱动)、RC滤波等基础电路,无需额外校准即可实现稳定性能;
  • E96系列阻值的一致性优于非标准阻值,批量采购时可避免阻值偏差导致的电路性能波动(如分压比误差)。

2. 功率与功耗

额定功率为1/16W(62.5mW),属于低功耗设计:

  • 适配微安级电流场景(如5V电源下,最大允许电流约0.23μA,I=√(P/R)=√(62.5e-3/267e3)≈0.23μA),适合低功耗设备延长电池续航;
  • 高温环境下需遵循风华的功率降额规范(如125℃时降额至50%,155℃时降额至30%),确保长期可靠性。

3. 温度系数与耐温范围

  • 温度系数(TCR)±100ppm/℃:表示温度每变化1℃,阻值变化约0.01%,属于厚膜电阻的常规稳定水平,可有效抑制温度波动对电路的影响(如25℃~125℃变化时,阻值最大偏差约1%);
  • 工作温度-55℃+155℃:覆盖工业级(-40℃85℃)与部分汽车级(-40℃~125℃)温度范围,可适应户外设备、高温工业环境等极端场景。

三、封装与工艺特性

1. 0402封装优势

  • 小型化:1.0mm×0.5mm的尺寸可大幅节省PCB空间,适配智能手机、智能穿戴等轻薄化设备的高密度布局(每平方厘米可贴装约2000个该电阻);
  • 贴装兼容性:符合SMD贴装标准,可通过自动贴片机高速贴装(速度≥10000片/小时),提升生产效率;
  • 散热性:虽为小型封装,但厚膜工艺的散热路径清晰,结合低功率设计,可避免局部过热导致的阻值漂移。

2. 厚膜工艺特点

厚膜电阻通过丝网印刷电阻浆料→高温烧结→电极制作工艺制成,相比薄膜电阻成本更低,相比碳膜电阻稳定性更好:

  • 抗过载能力:短时间过载(如2倍额定功率)下阻值漂移≤0.2%;
  • 抗潮湿与腐蚀:厚膜层附着力强(结合力≥10N/mm²),可抵御环境中的湿度与轻度腐蚀;
  • 成本优势:适合批量应用(如千万级采购),可降低终端产品的BOM成本约15%(对比同精度薄膜电阻)。

四、典型应用场景

RC-02K2673FT的参数特性使其适配多领域基础电路:

  1. 消费电子:智能手机的按键检测电路、平板电脑的信号分压电路(小空间、低功耗);
  2. 工业控制:温度传感器接口的电压采样电路、小型PLC的电阻网络(宽温范围适应车间温度变化);
  3. 汽车电子:仪表盘辅助显示的限流电路、车载USB接口的过流保护电路(耐温至155℃满足车载环境);
  4. 通信设备:小型基站的电源滤波电路、路由器的信号调理电路(高密度封装适配设备小型化);
  5. 医疗电子:便携式血糖仪的基础电阻电路、血压计的信号放大电路(低功耗延长电池续航)。

五、品质与可靠性保障

风华电子对该产品的品质管控严格:

  • 认证:符合RoHS 2.0、REACH环保标准,部分批次通过IATF 16949汽车电子认证;
  • 一致性:批量生产时阻值偏差、TCR等参数的离散性控制在±0.5%以内;
  • 可靠性测试:通过高温存储(155℃×1000h)、温度循环(-55℃~155℃×500次)等测试,阻值漂移≤0.5%,接触电阻变化≤5mΩ。

该产品凭借稳定的性能、小型化封装与成本优势,成为电子设备基础电路的常用选择,可满足不同行业对常规精度电阻的多样化需求。

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.
