风华0402B201K500NT 贴片多层陶瓷电容(MLCC)产品概述

一、产品基本定位与品牌背景

0402B201K500NT是国内被动元器件龙头厂商风华高科(FH) 推出的一款通用型贴片多层陶瓷电容(MLCC),属于风华MLCC系列的基础主力型号。该型号聚焦小型化电子电路的核心需求,兼顾容值稳定性、电压耐受能力与成本优势,广泛适配消费电子、工业控制等多领域的基础电路设计。

风华高科作为国内MLCC领域的核心供应商,拥有成熟的叠层陶瓷电容生产工艺,其产品通过ISO9001、IATF16949等认证,该型号延续了风华MLCC的高可靠性与批量一致性,是电子设计中常见的“通用型元件首选”。

二、核心性能参数解析

该型号的参数完全匹配常规电子电路的基础需求,关键指标如下:

参数项 具体规格 编码含义说明 标称容值 200pF 型号“201”=20×10¹pF 容值精度 ±10% 后缀“K”代表精度等级 额定电压(DC) 50V 后缀“500”=50×10⁰V 温度系数 X7R 核心介质特性 温度适用范围 -55℃~125℃ X7R标准温度区间 容值温度偏差 ±15%(典型值) 宽温下的稳定性表现

注:X7R介质的MLCC在1MHz以下频率范围内性能稳定,适合低频至中频电路。

三、封装规格与物理尺寸

该型号采用0402英寸封装(公制1005,即1.0mm×0.5mm),是MLCC最小的主流封装之一,具体物理参数(参考风华官方规格):

  • 长度:1.0±0.1mm;
  • 宽度:0.5±0.1mm;
  • 厚度:0.5±0.1mm(典型值);
  • 电极结构:内部镍基电极+外部镀锡焊盘,无极性设计简化安装。

封装工艺采用多层陶瓷叠层,通过高温烧结实现高容值密度,适配回流焊、波峰焊等常规贴片工艺,焊接可靠性达行业标准。

四、温度特性与稳定性

X7R是该型号的核心优势介质,平衡了宽温度适应性、容值稳定性与成本:

  1. 温度覆盖广:-55℃125℃,可应对工业环境(-40℃85℃)、车载低温场景(-55℃以上);
  2. 容值波动小:在-25℃~85℃范围内,容值偏差通常≤±10%,优于Y5V介质(±20%以上);
  3. 容值密度高:相比NPO高精度介质,X7R可在0402封装下实现200pF的常规容值,满足滤波、耦合需求。

五、典型应用场景

因小尺寸、性能稳定,该型号广泛应用于:

  1. 消费电子终端:智能手机、平板的电源滤波(电池纹波抑制)、音频信号耦合;
  2. 小型智能设备:蓝牙耳机、智能手环的辅助电路,适配模块高密度布局;
  3. 工业小系统:小型PLC、传感器节点的电源去耦,应对工业温度波动;
  4. 低功耗车载配件:车载USB充电器、小型显示屏的辅助电路(需匹配车载温度范围);
  5. 通信配件:路由器、小型基站的电源模块滤波,确保信号稳定。

六、可靠性与质量保障

风华对该型号进行了全面可靠性验证,符合多项行业标准:

  • 测试项目:高温存储(125℃×1000h)、温度循环(-55℃125℃×1000次)、耐湿(85℃/85%RH×1000h)、振动(102000Hz×2h);
  • 测试结果:容值变化率≤±10%,绝缘电阻≥10⁹Ω,满足长期工作需求;
  • 标准符合性:符合GB/T 26915、IEC 60384-1等国际/国内标准,可直接用于出口产品。

总结

0402B201K500NT作为风华通用型MLCC,以小尺寸、X7R宽温稳定性、50V电压耐受为核心优势,覆盖了大多数电子设备的基础电路需求,是性价比高、可靠性强的常规元件选择。

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
