RC-01W4701FT 产品概述

一、产品简介

RC-01W4701FT 为风华(FH)系列超小型贴片厚膜电阻,阻值 4.7kΩ,公差 ±1%,额定功率 50mW,工作温度范围 -55℃ 至 +125℃。封装为 0201(约 0.6 mm × 0.3 mm),专为高密度、高可靠性、小型化电路设计,适用于移动设备、可穿戴、消费电子和高密度互连电路的去耦与分压等应用。

二、主要技术参数

  • 品牌:FH(风华)
  • 型号:RC-01W4701FT
  • 封装:0201(超小型贴片)
  • 阻值:4.7 kΩ
  • 精度:±1%(F)
  • 温度系数(TCR):±200 ppm/℃
  • 额定功率:50 mW
  • 额定工作电压:25 V(厂商额定)
  • 工作温度:-55℃ ~ +125℃
  • 电阻类型:厚膜(Thick film)

注意:连续工作时实际允许施加的电压应同时满足功率限制(Vmax ≈ √(P·R))。按 50 mW 与 4.7 kΩ 计算,连续稳态下的功率限制对应电压约 15.3 V;虽然器件标注工作电压 25 V,但在长时间直流施加时应以功率限制为准,避免超过额定功率。

三、产品特性

  • 超小体积:0201 尺寸适合高密度贴片布局,节约 PCB 面积。
  • 精度稳定:±1% 阻值公差,适合对精度有中高要求的分压、采样电路。
  • 中等温漂:±200 ppm/℃ 的温度系数在厚膜产品中属常见水平,可满足普通温度稳定性要求。
  • 成本与可靠性平衡:厚膜工艺成本低、工艺成熟,适合量产应用。
  • 容易加工:兼容标准 SMT 流程及回流焊工艺。

四、可靠性与环境特性

  • 宽温工作范围(-55℃ 至 +125℃),适应一般工业与消费环境。
  • 厚膜电阻具有良好的抗机械振动和抗热冲击性能,但超小型封装对焊接和搬运更敏感。
  • 在高湿、高盐雾或长期高温高湿环境下,建议参考风华提供的湿热与耐焊剂试验数据,并在 PCB 设计时采取保护措施(如涂覆、封装或增加间距)。

五、安装与焊接建议

  • 建议使用精密贴片机与细间距吸嘴进行贴装,避免机械应力导致损伤。
  • 标准回流焊兼容,建议按照无铅回流曲线,严格控制峰值温度与升温速率;0201 元件对热应力敏感,尽量减少重复回流。
  • 焊盘设计应参考风华或 IPC 推荐的 0201 封装焊盘尺寸,使用合适的钢网厚度以保证焊点质量与贴装稳定性。
  • 对于长期可靠性,避免在器件上施加过大的弯曲应力或清洗过程中产生化学腐蚀。

六、典型应用场景

  • 手机、平板、笔记本等消费类便携终端的分压、电阻网络。
  • 可穿戴设备与 IoT 终端中要求小尺寸的阻值元件。
  • 高密度多层 PCB 的信号链、采样与基准电路。
  • 工业与汽车电子中用于非关键路径、普通精度需求的限流与分压场景(需评估环境与寿命要求)。

七、选型与注意事项

  • 使用时留有功率裕量,尤其在高环境温度或脉冲功率工况下应降低允许平均功率。
  • 若电路需长时间承受接近或超过 15 V 的直流电压,应选用阻值更高或功率更大的封装以避免过热失效。
  • 对温漂、噪声或长期漂移有严格要求的场合,可考虑金属膜或薄膜低 TCR 类别器件作为替代。
  • 0201 封装对制造可测试性(如手工焊接、维修)不友好,评估生产能力与测试策略后再行选用。

八、包装与订购信息

  • 常见包装形式为卷带(Tape & Reel),便于 SMT 贴片机取放;具体卷盘尺寸与数量请参阅风华产品目录或联系供应商确认。
  • 订购时请使用完整型号 RC-01W4701FT,并确认批次、封装及包装要求以确保与生产线兼容。

如需更详细的电气参数、温度功率降额曲线、焊接规范或封装机械图纸,请提供具体的采购批次或直接索取风华(FH)官方数据表。

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
