0402X225K100NT — 风华(FH) 0402 封装 2.2µF ±10% 10V X5R MLCC 产品概述

一、产品简介

0402X225K100NT 是风华(FH)推出的一款高容量多层陶瓷贴片电容(MLCC),标称容量 2.2µF,容差 ±10%(K),额定电压 10V,介质类别 X5R。0402 封装(约 1.0mm × 0.5mm)体积小、适合高密度表贴电路板,是移动设备、便携电子与空间受限电源前端去耦的理想选择。

二、主要电气参数

  • 容值:2.2µF(标称)
  • 容差:±10%(K)
  • 额定电压:10V DC
  • 介质:X5R(工作温度范围 -55°C ~ +85°C,温度引起的容量变化在规范范围内)
  • 封装:0402(毫米级微型)
  • 包装:卷带(NT 表示卷带/盘带包装,便于贴片机自动贴装)

三、温度与电压特性说明

X5R 介质在温度范围内具有较好的容值稳定性,但并非 NP0/C0G 类的温度线性,随温度或偏压会有可观的容量变化。在实际使用中需注意:

  • 温度特性:-55°C 至 +85°C 范围内容量变化受限于 X5R 规格(典型允许范围内)。
  • 直流偏压效应:高 DC 电压下,尤其是高比容量的小尺寸 MLCC,会出现明显容量下降。设计时建议留有裕量(常见做法为按实际需求将额定电压降额使用或在仿真中考虑 DC-bias 曲线)。

四、可靠性与常见失效模式

  • 优点:体积小、等效串联电阻(ESR)和等效串联电感(ESL)低,适合高速去耦与滤波。
  • 风险点:0402 小封装在焊接与机械应力下易出现电容片裂纹或端电极破坏;长期受热循环与板弯曲会影响寿命。建议在机械或振动环境下采取保护措施(如合理焊盘设计或加固)。

五、焊接与 PCB 设计建议

  • 焊接:适用于无铅回流工艺,峰值温度建议以工厂数据为准,一般无铅回流峰值约 245°C 左右;避免长时间高温暴露以降低热应力。
  • 焊盘建议:为保证焊接可靠性与机械强度,推荐按厂家/IPC 推荐焊盘设计并保持良好焊膏量与回流工艺;常见 0402 焊盘尺寸可参考 PCB 制造商与风华的推荐图。
  • 布局:靠近电源引脚或 IC 电源引脚放置以最小化走线感抗,多个并联以降低等效 ESR/ESL 并提高去耦效果。

六、典型应用

  • MCU/SoC 电源去耦与旁路
  • 移动终端、蓝牙/无线模组电源滤波
  • 电源管理模块、DC-DC 转换器输入/输出滤波
  • 各类高密度消费电子与物联网设备

七、订购与替代选型

  • 型号解析(示意):0402(封装) X225(2.2µF) K(±10%) 100(10V) NT(卷带包装)。建议在下单前参考风华正式 Datasheet 获得完整规格与可靠性认证信息。
  • 替代品选型:若需更稳定的温度系数或更小的 DC-bias 效应,可考虑同容量但更大封装或不同介质(如 X7R、或并联多个更小容值器件);在汽车或高可靠场景下,须确认器件是否满足 AEC-Q200 等相关认证。

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
