风华FH 0402B273K500NT多层陶瓷电容器(MLCC)产品概述

一、产品基本定位与型号解析

该产品为风华FH品牌旗下通用型多层陶瓷电容器(MLCC),型号命名规则直接指向核心参数:

  • 「0402」:英制封装尺寸(对应公制1005,即长1.0mm×宽0.5mm);
  • 「B」:风华通用MLCC系列标识;
  • 「273」:容值编码(27×10³ pF=27nF);
  • 「K」:容值精度(±10%);
  • 「500」:额定直流电压(50V DC);
  • 「NT」:端电极+包装组合标识(风华三层电极结构+卷带编带包装)。

产品定位为中小功率电路的通用被动元件,兼顾容值稳定性与成本优势,适配多数消费电子、工业控制等场景。

二、核心性能参数详解

1. 容值与精度

标称容值为27nF(27000pF),精度等级为**±10%(K级)**,满足多数电路对容值偏差的要求(如电源滤波、信号耦合无需超高精度)。

2. 额定电压

额定直流电压为50V DC,可承受最大1.5倍额定电压的短期浪涌,适用于低压直流系统(如5V/12V/24V辅助电源)。

3. 温度系数(X7R)

采用X7R温度特性(MLCC应用最广泛的类别之一):

  • 工作温度范围:-55℃~+125℃;
  • 容值变化率:全温度范围内≤±15%(相对于25℃基准值);
  • 对比NPO(温度稳定)与Y5V(容值变化大),X7R平衡了温度稳定性与容值密度,更适合通用场景。

4. 补充性能(典型值)

  • 绝缘电阻(IR):≥10¹⁰Ω(25℃,额定电压下);
  • 损耗角正切(tanδ):≤0.025(1kHz,25℃);
  • 频率特性:10kHz~100MHz范围内容值变化≤5%(适配射频辅助电路)。

三、封装与物理特性

1. 封装尺寸

0402英制封装(公制1005)关键尺寸:

  • 长度:1.0±0.05mm;宽度:0.5±0.05mm;厚度:典型0.5mm(最大0.55mm);
  • 端电极宽度:0.25mm,确保SMT焊接可靠性。

2. 端电极结构

风华专利三层电极设计:

  • 内层:镍(Ni)基电极(高导电、抗腐蚀);
  • 中间层:铜(Cu)过渡层(增强焊接附着力);
  • 外层:锡(Sn)镀层(无铅,RoHS合规);
    兼容回流焊、波峰焊,焊接温度≥260℃(10秒内无失效)。

3. 包装方式

标准卷带编带(IEC 60286-2标准):

  • 编带宽度:8mm(适配小型贴片机);
  • 每盘数量:5000个(或10000个,依订单);
  • 防静电包装(表面电阻≤10¹¹Ω),防止静电损伤。

四、典型应用场景

因参数平衡,广泛应用于:

  1. 消费电子:手机/平板电源滤波(电池管理去耦)、音频耦合;
  2. 汽车电子:车载辅助电路(仪表盘背光、传感器接口);
  3. 工业控制:PLC模块信号滤波、小型电源输出滤波;
  4. 通信设备:路由器/交换机射频前端耦合、电源去耦;
  5. 智能家居:智能音箱、安防摄像头电源与信号处理。

五、可靠性与环境适应性

风华MLCC通过多项认证,稳定性可靠:

  • 符合IEC 60384-1、GB/T 2693标准;
  • 耐焊接热:260℃回流焊3次循环,容值变化≤5%,绝缘电阻≥10⁹Ω;
  • 湿热试验:85℃/85%RH环境1000小时,容值变化≤10%,无外观损坏;
  • 寿命测试:额定条件下MTBF≥10⁶小时(超100万小时无故障);
  • 环保合规:RoHS 2.0、REACH,无铅无镉。

六、选型与替代参考

若需调整参数,可参考同系列替代:

  1. 容值调整:0402B223K500NT(22nF,±10%)、0402B333K500NT(33nF,±10%);
  2. 电压提升:0402B273K100NT(100V DC,27nF,±10%);
  3. 精度提升:0402B273J500NT(±5%精度,27nF,50V);
  4. 温度特性调整:0402B273J500NT(NPO,±5%,温度稳定)。

替代原则:额定电压≥原型号、温度系数兼容设计、封装匹配贴片机规格。

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
