RC-02K2321FT 产品概述

一、产品简介

RC-02K2321FT 是风华(FH)系列0402封装的厚膜贴片电阻,标称阻值2.32 kΩ,精度±1%,额定功率62.5 mW(1/16W),额定工作电压50 V,温度系数(TCR)±100 ppm/℃,工作温度范围-55℃至+155℃。0402(1005公制)超小封装适配高密度贴片电路板,适用于空间受限且要求中高精度的电子产品。

二、结构与主要特性

  • 结构:厚膜电阻工艺,烧结银/金属氧化物阻性层沉积于陶瓷基板,外覆保护釉层,端电极为镀锡处理,适合回流焊接。
  • 尺寸:0402(约1.0×0.5 mm),适配主流贴片机和回流工艺。
  • 电气特性:
    • 阻值:2.32 kΩ,公差±1%;
    • 额定功率:62.5 mW(室温下);
    • 额定工作电压:50 V(器件最大电压),但受功率限制;
    • 温度系数:±100 ppm/℃;
    • 工作温度:-55℃ ~ +155℃。

三、使用注意与设计要点

  • 功率/电压限制:尽管标称工作电压为50 V,但在实际设计中必须遵守功率极限。跨阻器的最大安全电压可由 Vmax = sqrt(P·R) 计算:Vmax ≈ sqrt(0.0625 W × 2320 Ω) ≈ 12 V。即若电压超过此值,会因功率超载导致过热损坏。
  • 温漂影响:TCR ±100 ppm/℃ 意味着温度每变化1℃,阻值约变化0.01%;例如从25℃升至85℃(Δ60℃),阻值可能变化约0.6%,应与±1%公差一并考虑系统精度。
  • 降额建议:建议在环境温度超过70℃时按线性降额至155℃为0。高湿、高震动环境需做额外验证。
  • 焊接工艺:推荐遵循无铅回流曲线(参考J-STD-020/IPC),峰值温度控制在260℃左右、峰值时间短于10秒,避免二次加热多次超过峰值。

四、典型应用场景

  • 高频器件周边的分压、限流和偏置网络;
  • 移动设备、可穿戴、物联网模块等空间受限的电路;
  • 信号采集、ADC前端的阻抗配合与滤波电路(在对噪声和温漂要求不高的场合);
  • 大批量表面贴装产品的通用电阻解决方案。

五、封装与质量与订购信息

  • 包装方式:标准卷带(Tape & Reel),适配自动贴片机;常见卷盘尺寸7英寸/13英寸,具体包装请以厂家说明为准。
  • 可靠性:厚膜电阻经过焊接热循环、湿热和机械冲击等常规可靠性测试,符合行业通用可靠性要求。对关键应用建议索取风华出具的可靠性报告或进行样机测试验证。
  • 型号说明:RC-02K2321FT 标识0402封装(RC-02),阻值2.32K(2321),精度±1%,工厂料号系列(FT)。具体订货编码与包装数量请咨询供应商或参考产品数据手册。

六、选型建议与替代方案

  • 若对温漂、低噪声或长期稳定性有更高要求,建议考虑金属膜或薄膜电阻(更低TCR、更佳稳定性);
  • 若负载功率或浪涌要求高于62.5 mW,应选用更大封装或更高功率等级的电阻(如0603、0805或更大封装);
  • 在高电压应用中,优先按功率限值计算实际允许电压,而非仅依赖名义工作电压。

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
