C0402C470J5GAC7867 产品概述

一、产品简介

C0402C470J5GAC7867 为 KEMET(基美)生产的陶瓷片式多层电容器(MLCC),封装规格为 0402(约 1.0 mm × 0.5 mm)。主要电气参数为:容值 47 pF、精度 ±5%、额定电压 50 V、介质材料 C0G(亦称 NP0)。该系列以电容稳定性高、介质损耗低著称,适用于对温度与频率稳定性要求较高的小信号和高频电路。

二、主要性能特点

  • 稳定性:C0G/NP0 属一类介质,温度系数接近 0(典型 0 ±30 ppm/°C),在广泛温度范围内容值波动极小。
  • 低损耗:介质损耗角正切低,Q 值高,适合射频及谐振电路。
  • 低电压依赖性:与 X7R、X5R 等介质相比,C0G 几乎无直流偏压引起的容量衰减。
  • 小型化:0402 封装支持高密度 PCB 布局,适合便携与空间受限设计。
  • 工艺兼容:表面贴装(SMD),适用于自动化贴片与回流焊流程。

三、典型应用场景

  • 高频滤波、匹配与谐振网络(RF 前端、射频滤波器、天线匹配)。
  • 振荡器与定时电路(晶体/振荡器负载电容、参考电路)。
  • 精密模拟电路(采样、采集、补偿网络)需稳定电容的场合。
  • 高频耦合/去耦与阻抗调整等对容值稳定性有严格要求的场合。

四、封装与焊接建议

  • 尺寸:0402(约 1.0 mm × 0.5 mm),适配相应的 PCB 焊盘尺寸,请参考制造商推荐的 land pattern。
  • 回流焊:兼容常见无铅回流工艺,建议遵循 IPC/JEDEC 指导,回流峰值温度一般控制在 ≤260°C。
  • 贴装注意:0402 体积小,贴装需确保吸嘴定位精度与焊膏量控制;避免过量焊膏导致偏位或桥焊。
  • 可靠性:为避免焊接应力引起裂纹,推荐合理设计焊盘延伸与过孔布局,回流后可进行目视/光学或 X 射线检查。

五、储存与处理

  • MLCC 对潮气敏感,长时间暴露在湿气中可能影响焊接质量。建议未使用的卷带密封保管,必要时按厂商建议回流前进行烘烤除湿。
  • 装配时避免对元件施加机械应力或弯曲 PCB 边缘,以防产生裂纹或损坏。

六、订购与包装

  • 包装方式通常为卷带(Tape & Reel),适配高速贴片机自动上料。
  • 订购时请核对完整料号与包装代码以确保料件、包装和出货批次符合生产需求。

七、参数一览(摘要)

  • 容值:47 pF
  • 精度:±5%(J)
  • 额定电压:50 V DC
  • 介质:C0G / NP0(温度系数约 0 ±30 ppm/°C)
  • 封装:0402(SMD)
  • 制造商:KEMET(基美)

总结:C0402C470J5GAC7867 以其 C0G 介质的优良电气稳定性和 0402 小型封装的高密度适配性,适合高频、精密和空间受限的电子产品设计。在实际应用中,按制造商推荐的 PCB 焊盘与回流工艺进行设计和装配,能获得最佳的电气特性与长期可靠性。若需更详细的焊盘尺寸、回流曲线或环境/可靠性测试数据,建议参阅 KEMET 官方数据手册或联系技术支持。

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
