0402B474K100NT贴片电容产品概述

一、产品基本属性

0402B474K100NT是风华电子(FH) 推出的一款0402封装多层陶瓷贴片电容(MLCC),核心参数清晰明确:

  • 封装尺寸:英制0402(公制1005),实际尺寸约1.0mm×0.5mm×0.5mm(长×宽×厚,具体以官方规格书为准);
  • 容值:型号中“474”为容值代码,对应容值47×10⁴ pF = 470nF;
  • 精度:“K”标识精度等级,即**±10%**;
  • 额定电压:“100”对应直流额定电压10V;
  • 温度系数:X7R(符合EIA国际标准),工作温度范围-55℃至+125℃,容值变化≤±15%;
  • 环保特性:无铅环保设计,符合RoHS 2.0、REACH等全球环保法规。

型号字符分解:0402(封装代码)、B(MLCC材质/系列标识)、474(容值代码)、K(精度代码)、100(电压代码)、NT(风华内部封装/无铅工艺标识)。

二、核心性能特点

1. 宽温区容值稳定

X7R温度系数是该产品的核心优势:在-55℃至+125℃的宽温度范围内,容值波动控制在±15%以内,可有效避免因温度变化导致的电路性能漂移,适配工业级、消费级设备的多样化环境需求。

2. 精准容值与批次一致性

±10%的K级精度,结合风华自动化生产工艺,产品批次间容值偏差小,一致性高,可降低电路设计中的容值风险,尤其适合对滤波、耦合效果有稳定要求的场景。

3. 小体积高密度集成

0402封装(1005公制)是小型化电子设备的主流选择,体积仅为传统插件电容的1/10左右,可显著提升电路集成密度,适配智能手机、智能手表等紧凑空间的设计需求。

4. 低电压场景适配性

10V DC额定电压虽为低电压规格,但覆盖了绝大多数消费电子、IoT设备的电源系统(如3.3V、5V电源滤波)需求,同时避免了高电压规格带来的体积和成本冗余。

5. 高可靠性与耐候性

  • 耐焊接性能:峰值焊接温度≥260℃,符合回流焊工艺要求;
  • 老化稳定性:湿热老化(85℃/85%RH)1000h后,容值变化≤±10%,满足长期使用需求。

三、典型适用场景

该产品因体积小、容值稳定、电压适配性强,广泛应用于以下领域:

  1. 消费电子终端:智能手机、智能手表、平板电脑的CPU供电滤波、音频模块信号耦合;
  2. IoT与可穿戴设备:蓝牙/WiFi模块去耦、传感器节点(如温度/湿度传感器)滤波;
  3. 小型电子模块:电源管理IC(PMIC)配套电容、射频前端(RF Front-end)匹配电容;
  4. 工业控制小单元:PLC辅助模块、低电压控制电路的滤波电容,适应工业级温度环境。

四、选型与应用注意事项

  1. 电压降额设计:实际工作电压建议不超过额定电压的80%(即8V以内),避免长期过载导致电容失效;
  2. 温度范围匹配:若应用场景温度超出-55℃+125℃(如极端高温150℃以上),需更换X8R(-55150℃)或NPO(容值更稳定但容值偏小)材质电容;
  3. 焊接工艺要求:0402封装尺寸小,回流焊需控制峰值温度245℃~260℃、时间≤10s,避免虚焊或焊锡桥接;
  4. 容值余量考量:设计滤波电路时建议预留±20%余量,抵消±10%精度的偏差影响。

五、品牌与品质保障

风华电子(FH)是国内被动元器件龙头企业,拥有30余年MLCC生产经验,0402B474K100NT具备以下品质保障:

  • 符合IEC 60384-14、JIS C 5102等国际标准;
  • 批次一致性管控严格,容值、温度特性符合规格书要求;
  • 提供完整RoHS、REACH检测报告,支持全球市场准入;
  • 售后技术支持完善,可协助解决选型、焊接等应用问题。

该产品是低电压、小型化电路的高性价比选择,可满足消费电子、IoT等领域的多样化需求。

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
