0805B224K101NT 风华贴片多层陶瓷电容(MLCC)产品概述

一、产品基本信息与型号解析

0805B224K101NT是风华高科(FH) 推出的通用型贴片多层陶瓷电容(MLCC),型号字符对应核心参数:

  • 0805:英制封装尺寸(0.08英寸×0.05英寸),公制为2.0mm×1.25mm;
  • B:风华内部封装/系列代码,适配标准0805贴片封装;
  • 224:容值编码(22×10⁴pF),标称容值220nF;
  • K:容值精度(±10%);
  • 101:额定直流电压编码(10×10¹V),即100V DC;
  • NT:温度特性代码,对应行业标准X7R 温度系数。

该产品为无铅环保型,符合RoHS 2.0及REACH规范,兼容SMT自动贴装工艺。

二、核心电气性能参数

参数项 典型值/标称值 测试条件 标称容值 220nF(224pF) 25℃,1kHz 容值精度 ±10%(K档) 25℃,1kHz 额定直流电压(Vdc) 100V 连续工作电压上限 绝缘电阻(IR) ≥10⁹Ω·μF 25℃,50V DC,1min 损耗角正切(DF) ≤1.5% 25℃,1kHz 工作温度范围 -55℃~+125℃ 长期稳定工作区间

注:交流应用需降额(峰值电压≤70V AC),避免介质击穿。

三、封装与物理特性

  • 尺寸规格:公制2.0±0.2mm(长)×1.25±0.15mm(宽)×0.8±0.1mm(厚);
  • 电极结构:端电极采用镍(Ni)打底+锡(Sn)镀层,焊接兼容性优异;
  • 介质材料:钛酸钡基陶瓷(X7R特性),多层叠层设计提升容值密度;
  • 环保要求:无铅(Pb≤100ppm)、无镉、无汞,满足欧盟环保指令。

四、温度特性与稳定性

X7R温度系数是该产品的核心优势:

  • 宽温覆盖**-55℃~+125℃**,适配工业级极端环境;
  • 温度变化时容值漂移≤±15%(行业标准),远优于Y5V(±20%~-80%)等低成本材料;
  • 对比NPO(温度系数0±30ppm/℃),X7R容值范围更宽(220nF适配中容值需求),平衡了稳定性与实用性。

五、典型应用场景

该产品因100V中压、宽温稳定特性,广泛用于:

  1. 电源滤波/去耦:中高压直流电源(如12V~48V升压电路、工业电源模块)的噪声抑制;
  2. 信号耦合:中低频信号(10kHz~1MHz)的耦合,如通信设备中频电路;
  3. 工业控制:PLC、变频器等设备的电源端滤波,适配车间宽温环境;
  4. 消费电子:高端机顶盒、路由器的电源模块,提升供电稳定性;
  5. 汽车电子:车载辅助系统(非安全类)的电源滤波(部分型号满足AEC-Q200车规)。

六、可靠性与质量保障

风华作为国内MLCC龙头,该产品通过多项严苛测试:

  • 高温高湿测试:85℃/85%RH,1000h后容值变化≤±10%,绝缘电阻≥10⁸Ω·μF;
  • 温度循环测试:-55℃~+125℃,1000次循环无开裂、电性能失效;
  • 焊接可靠性:回流焊(260℃峰值,10s)后无爆瓷、端电极脱落;
  • 寿命指标:额定条件下MTBF≥10⁶小时,符合工业级可靠性要求。

七、选型与使用注意事项

  1. 电压降额:交流峰值电压≤额定直流电压的70%(70V AC),高温(>125℃)时降额至70V DC;
  2. 焊接工艺:回流焊温度曲线符合J-STD-020,避免局部过热;
  3. 储存条件:常温(25±5℃)、湿度≤60%,储存期≤12个月,开封后尽快使用;
  4. 机械应力:贴片后避免弯曲、撞击,防止陶瓷介质开裂;
  5. 替换选型:同参数可替换型号包括村田GRM188R61C224KA73D、三星CL08B224KA5NNNC,需确认封装一致性。

该产品兼顾性能、可靠性与成本,是中高压通用电路的优选MLCC。

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
