RC-02K2672FT 厚膜固定电阻器产品概述

一、产品基本定位与封装信息

RC-02K2672FT是风华FH品牌推出的表面贴装厚膜固定电阻器,属于小功率贴片电阻范畴。其封装为0201规格(行业命名中“RC-02K”对应0201封装,尺寸约1.6mm×0.8mm),适配自动化贴装生产线,可有效节省PCB布局空间,适合高密度电路设计。产品核心定位为满足消费电子、工业控制、汽车电子等领域对小尺寸、稳定阻值、宽温适应性的需求。

二、核心电气参数详解

本产品的电气参数经严格校准,关键指标如下:

1. 阻值与精度

  • 标称阻值:26.7kΩ(三位数字标识为“2672”,即267×10²=26700Ω);
  • 精度等级:±1%(工业级常用精度,无需额外校准即可实现稳定信号输出,满足多数电路的精度需求)。

2. 功率与降额要求

  • 额定功率:62.5mW(0.0625W,为0201封装电阻的典型额定功率);
  • 降额建议:实际应用需遵循80%功率降额(即实际功耗≤50mW),避免长期过热导致阻值漂移或失效。

3. 工作电压与匹配

  • 最大工作电压:50V;
  • 电压匹配说明:由公式P=U²/R计算,50V下功率约93.6mW(超过额定功率),因此实际工作电压需结合降额功率确定(如50mW时最大电压约36.5V),勿直接使用50V额定电压。

4. 温度系数(TCR)

  • 指标:±100ppm/℃(即温度每变化1℃,阻值变化±0.01%);
  • 温度影响:以工作温度范围-55℃~+155℃为例,温差210℃时阻值最大变化±2.1%,叠加±1%精度,总阻值变化范围约±3.1%,可满足一般场景的温度适应性需求。

三、结构与工艺优势

本产品采用厚膜工艺制造,核心结构与工艺优势如下:

  1. 基片与电阻层:以氧化铝陶瓷为基片(绝缘性好、热稳定性高),表面印刷厚膜电阻浆料后经高温烧结形成稳定电阻层;
  2. 电极设计:采用银/镍/锡三层电极(提高焊接性与抗硫化性能),焊接后附着力强,不易脱落;
  3. 保护层:涂覆环氧树脂涂层(防潮、防机械损伤),可适应潮湿、多尘等复杂环境;
  4. 调阻精度:风华FH的厚膜调阻工艺成熟,可稳定实现±1%精度,批量一致性好。

四、典型应用场景

因尺寸小、功耗低、宽温适应性强,本产品适用于以下场景:

  1. 消费电子:手机、平板、智能穿戴的信号调理电路(如音量调节、触控感应分压)、电源滤波电路;
  2. 工业控制:PLC(可编程逻辑控制器)的I/O接口、传感器信号放大(如温度、压力传感器前置放大);
  3. 汽车电子:低功耗辅助电路(如仪表盘背光控制、车门传感器信号处理),155℃工作温度覆盖部分汽车级需求;
  4. 通信设备:基站射频前端辅助电路、电源模块分压/限流电阻;
  5. 医疗电子:小型医疗设备(血糖仪、血压计)的传感器信号调理,稳定阻值保障测量精度。

五、可靠性与环境适应性

本产品符合多项国际可靠性标准,可满足不同场景的长期使用:

  • 温度范围:-55℃+155℃(覆盖工业级-40℃+85℃及部分汽车级-40℃~+125℃需求);
  • 耐湿性能:85℃/85%RH环境下1000小时测试,阻值变化≤1%;
  • 振动与冲击:符合IEC 60068-2-6(振动10~2000Hz,加速度1g)、IEC 60068-2-27(冲击50g,11ms脉冲),测试后阻值变化≤0.5%;
  • 长寿命:额定功率下连续工作10000小时,阻值变化≤0.5%。

六、应用注意事项

  1. 降额使用:严格遵循80%功率降额,避免长期过热;
  2. 电压匹配:实际工作电压需结合降额功率计算,勿超额定电压;
  3. 焊接工艺:0201封装回流焊参数建议:峰值温度240~250℃,时间≤10s,避免焊接损伤;
  4. 静电防护:厚膜电阻对静电敏感,需用抗静电袋包装,操作时佩戴防静电手环;
  5. 温度评估:温度变化剧烈场景(如-40℃~+125℃)需评估阻值变化对电路的影响,若需更高精度可选择低TCR电阻。

本产品以稳定的性能、小尺寸优势,成为各类电子设备中小功率电阻应用的可靠选择。

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.
