风华RC-02K6800FT厚膜贴片电阻产品概述

一、产品基本定位与标识

RC-02K6800FT是风华电子(FH) 推出的0402封装厚膜贴片电阻,属于通用型高精度电阻范畴。型号命名清晰对应核心属性:

  • “RC”代表厚膜电阻工艺;
  • “02”对应英制0402封装;
  • “K”标识精度±1%;
  • “6800”为阻值编码(680Ω);
  • “FT”为风华通用电阻系列标识。

该电阻以“小体积+稳定性能+高性价比”为核心优势,适配多数电子电路的基础阻抗控制需求,是消费电子、工业控制等领域的主流选型之一。

二、核心性能参数解析

该电阻的参数完全覆盖主流电子设计的常规需求,关键指标如下:

  1. 阻值与精度:额定阻值680Ω,精度±1%,满足工业级电路对阻值一致性的要求,无需额外校准即可实现分压、限流等功能;
  2. 功率等级:额定功率62.5mW,为0402封装厚膜电阻的标准规格,需遵循功率降额原则(建议实际使用功率≤37.5mW,即60%降额),避免过热导致阻值漂移;
  3. 工作电压:最大工作电压50V(直流/交流峰值电压),需严格控制电路电压不超此值,防止绝缘击穿;
  4. 温度系数(TCR):±100ppm/℃,即温度每变化1℃,阻值变化±100Ω/10⁶Ω,在宽温范围内阻值漂移可控,适合高低温交替场景;
  5. 工作温度范围:-55℃~+155℃,符合汽车电子、工业自动化等领域的极端环境要求。

三、封装工艺与结构特点

  1. 0402小封装:英制尺寸为1.0mm(长)×0.5mm(宽)×0.45mm(厚),适配高密度PCB设计,可有效降低电路占用空间,提升设备集成度;
  2. 厚膜烧结工艺:采用丝网印刷将电阻浆料烧结在陶瓷基片上,具有成本低、抗老化能力强、性能稳定的特点,优于薄膜电阻的性价比,适合大规模量产;
  3. 端电极设计:端电极采用“镍底层+锡表层”镀层,兼容回流焊、波峰焊等主流焊接工艺,焊接附着力强,可避免虚焊、脱焊问题,耐焊接热性能符合J-STD-020标准。

四、适用典型应用场景

RC-02K6800FT因性能均衡、体积小巧,广泛应用于以下领域:

  1. 消费电子:手机、平板、智能穿戴的信号分压电路、LED指示灯限流、电源管理反馈电阻;
  2. 工业控制:PLC、传感器接口的阻抗匹配、电机驱动电路限流;
  3. 汽车电子:车载中控、仪表板的背光调节、按键检测电路(适配汽车级宽温);
  4. 通信设备:路由器、基站射频前端的阻抗匹配、信号衰减网络;
  5. 医疗电子:小型家用医疗设备(血压计、血糖仪)的基础电路(低功耗+小体积)。

五、环境可靠性与稳定性

  1. 环境应力测试:经过1000次温度循环(-55℃~+155℃)、1000小时湿度测试(85℃/85%RH),阻值变化率≤±0.5%,符合IEC 60068系列标准;
  2. 长期可靠性:平均无故障工作时间(MTBF)超10⁶小时,厚膜浆料稳定性高,可避免长期使用中的阻值漂移;
  3. 机械强度:陶瓷基片满足SMT贴装要求,可承受贴装过程中的轻微应力,不易碎裂。

六、选型与使用注意事项

  1. 功率降额:实际功率≤37.5mW,避免过热导致性能下降;
  2. 电压限制:电路峰值电压≤50V,防止绝缘击穿;
  3. 焊接工艺:回流焊峰值温度240℃~250℃(时间≤10秒),波峰焊温度≤245℃;
  4. 储存条件:未焊接电阻储存在25℃±5℃、湿度≤60%的干燥环境,避免受潮;
  5. 精度匹配:若需更高精度(如±0.1%),需选择风华精密系列,但本型号±1%已覆盖90%以上常规应用。

RC-02K6800FT凭借均衡的性能、稳定的可靠性及高性价比,成为电子设计中0402封装厚膜电阻的核心选型,适配多行业的电路需求。

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
