风华RC-02K1151FT厚膜贴片电阻产品概述

RC-02K1151FT是风华高科(FH) 推出的通用型厚膜贴片电阻,针对中低功率电路的精准阻抗匹配、信号调理及分压设计,兼顾电气精度、环境适应性与成本优势,广泛适配消费电子、工业控制等多领域应用。

一、产品基本属性

该电阻属于厚膜贴片电阻(Thick Film Chip Resistor),采用风华成熟工艺制造:通过丝网印刷将钌基电阻浆料沉积在高纯度氧化铝陶瓷基片上,经高温烧结形成电阻层,再经电极制作、环氧树脂封装及激光微调,实现精准阻值控制。

产品型号命名规则:

  • RC:风华厚膜贴片电阻系列代号;
  • 02:封装前缀(对应英制0402封装,公制1005,尺寸1.0mm×0.5mm);
  • K1151:阻值代码(K表示±1%精度,1151=115×10¹=1.15kΩ);
  • FT:通用功率/精度等级代码。

二、核心电气性能参数

RC-02K1151FT的参数针对通用电路优化,关键指标如下:

参数 规格值 说明 标称阻值 1.15kΩ(1150Ω) 激光微调至标准阻值 阻值精度 ±1% 满足大多数电路阻抗匹配需求 额定功率(@70℃) 62.5mW 连续工作功率上限 温度系数(TC) ±100ppm/℃ 温度每变1℃,阻值变化±100×10⁻⁶ 工作温度范围 -55℃~+155℃ 覆盖工业级宽温环境 最大工作电压 ~27V(P=V²/R计算) 70℃时电压上限 温度循环稳定性 ≤±2%(-55~155℃循环) 宽温下阻值漂移可控

关键参数解读:

  • 精度±1%:替代部分薄膜电阻,平衡精度与成本;
  • TC±100ppm/℃:-55~155℃范围内,阻值最大变化24.15Ω(约2.1%),叠加精度后总误差≤±3.1%;
  • 62.5mW功率:适配低功耗电路(如传感器调理、MCU外围),无需额外降额。

三、环境适应性与可靠性

RC-02K1151FT符合工业级可靠性标准:

  1. 宽温稳定性:-55~155℃长期工作,阻值漂移≤±2%;
  2. 耐湿性:85℃/85%RH湿热试验1000h后,阻值变化≤±1%,电极无氧化;
  3. 机械强度:环氧树脂封装抗振动(10~2000Hz,2g)、冲击(1000m/s²);
  4. ESD防护:厚膜结构耐受≥2kV接触放电,无需额外防护。

四、封装与物理特征

采用0402封装(最小通用封装之一),物理参数:

  • 尺寸:1.0mm(长)×0.5mm(宽)×0.35mm(高);
  • 重量:约0.5mg;
  • 电极:三层结构(镍+锡/铅,RoHS兼容),焊接兼容性好;
  • 基片:氧化铝陶瓷,热导率≥20W/(m·K),散热优异。

五、典型应用场景

  1. 消费电子:智能手机/手环的射频偏置、传感器分压;电视/机顶盒电源分压;
  2. 工业控制:PLC模拟量输入采样、小型传感器信号放大;
  3. 汽车电子:车载娱乐音频调理、BCM低功耗外围;
  4. 物联网:低功耗MCU外围、无线模块阻抗匹配。

六、选型与应用注意事项

  1. 功率降额:70℃以上需降额(如125℃时降额至50%,即31.25mW);
  2. 焊接工艺:推荐回流焊(245~260℃,≤10s),避免波峰焊损伤;
  3. 静电防护:生产中佩戴防静电手环;
  4. 替代选型:更高精度选风华薄膜电阻,更高功率选0603封装同阻值产品。

七、品牌与质量保障

RC-02K1151FT由风华高科生产,该企业是国内被动元件龙头,产品通过ISO 9001、ISO 14001及RoHS认证,部分批次符合AEC-Q200汽车级标准,供货稳定。

总结:RC-02K1151FT是高性价比通用厚膜电阻,兼顾小尺寸、宽温、精准度与成本,是消费电子、工业控制的理想选型。

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
