RC-02K471JT 产品概述

一、产品简介

RC-02K471JT 是风华(FH)品牌一款常规贴片厚膜电阻,封装为 0402(约 1.0 mm × 0.5 mm),标称阻值 470Ω,公差 ±5%。该型号为低功率、小体积的通用电阻器,适用于高密度表面贴装电路板(SMT)中对体积和成本有严格要求的场合。

二、主要参数

  • 电阻类型:厚膜电阻
  • 阻值:470Ω
  • 精度:±5%
  • 功率额定:62.5 mW
  • 最大工作电压:50 V
  • 温度系数(TCR):±100 ppm/℃(约 0.01%/℃)
  • 工作温度范围:-55℃ ~ +155℃
  • 封装:0402(风华品牌)

三、特性与优势

  • 小尺寸高密度:0402 尺寸便于在空间受限的移动终端、便携设备和智能穿戴产品中实现高密度布线。
  • 成本效益高:厚膜工艺成熟、成本低,适合大批量通用电路设计。
  • 宽温工作范围:-55℃ 至 +155℃ 的耐温能力满足大多数工业与消费类环境。
  • 良好温漂控制:TCR ±100 ppm/℃ 可保证在中低精度应用中阻值稳定性符合需求。

四、典型应用场景

  • 信号通路限流、上拉/下拉电阻
  • 滤波与分压网络中的定值元件
  • MCU / 模拟芯片输入输出保护与阻抗匹配
  • 消费电子、通信设备、可穿戴、物联网节点等功耗受限的场景

五、设计与使用注意事项

  • 功率与散热:62.5 mW 为组件在标准实验条件下的额定功率,实际使用中受 PCB铜箔面积、铺铜及周围元件散热影响,建议在设计时留有足够余量并参考厂商的功率热特性。
  • 电压限制:最高允许工作电压为 50 V,超过该值可能引起电阻击穿或击穿相关的可靠性问题。
  • 温漂影响:TCR ±100 ppm/℃ 表示温度变化会导致阻值微幅变化,精密或温度敏感电路应评估温度引起的误差累积。
  • 焊接工艺:适配常见回流焊工艺,推荐按 PCB 制程规范控制回流峰值温度与时间,避免多次高温循环可能导致元件应力。

六、可靠性与品质控制

风华作为主流被动元件厂商,RC-02K471JT 在生产与检验上通常符合行业常规的质量控制流程(如外观、阻值、过载与温度循环等试验)。在采购与设计时,可向供应商索取更详细的可靠性报告(加速寿命、湿热、耐焊接等)以满足特定行业认证需求。

七、封装与采购建议

  • 封装形式为 0402 卷带盘装(Tape & Reel),便于 SMT 贴装生产线使用。
  • 设计备料时建议考虑阻值公差 ±5% 带来的库存与替代件策略;若需更高精度或更低温漂,应选用薄膜或精密电阻替代。
  • 采购前核对环境与应用要求(如高温、高湿或高电压场景),以确保该型号满足长期可靠性需求。

总结:RC-02K471JT(FH,0402,470Ω ±5%)为一款性价比高、适用于高密度低功耗电路的通用贴片厚膜电阻。合理的热设计与工艺控制可保证其在大多数消费与工业应用中的稳定表现。若需更详细的电气热参数或可靠性测试数据,请联系风华或授权分销商获取完整数据手册。

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
