风华FH 0201B122K500NT多层陶瓷电容器(MLCC)产品概述

一、产品基本属性与命名解析

该产品是风华电子(FH) 推出的0201封装通用型多层陶瓷电容器(MLCC),属于商业级器件,核心定位为小型化电子设备的滤波、耦合与旁路应用。其命名遵循风华MLCC标准逻辑,各部分含义清晰:

  • 0201:英制封装代号,对应公制尺寸为0.6mm(长)×0.3mm(宽)×0.3mm(厚)(±0.03mm/±0.05mm公差);
  • B:风华针对0201小封装的通用系列标识;
  • 122:容值代码(前两位有效数+第三位倍率),即(12×10^2=1200pF=1.2nF);
  • K:容值精度,对应±10%;
  • 500:额定直流电压,即50V DC;
  • NT:风华特有的端电极与环保标识(Ni/Sn镀层,符合RoHS 2.0、REACH指令)。

二、核心电气性能参数

该产品电气性能符合风华MLCC通用标准,关键参数如下(测试条件均为25℃、1kHz基准):

参数项 规格值 实际应用参考 标称容值 1.2nF(122) 适用于射频滤波、电源旁路 容值精度 ±10%(K级) 满足大部分通用电路需求 额定直流电压 50V DC 最大工作电压(建议降额) 损耗角正切(tanδ) ≤2.5% 低损耗适合信号调理 漏电流(IR) ≤0.6nA(典型值) 公式:(I≤10^{-6}×V×C) 工作温度范围 -55℃~+125℃ X7R中温稳定型温度系数

三、封装与机械特性

0201封装是目前小型化设备的主流选择,该产品机械特性适配贴装与使用需求:

  1. 尺寸公差:严格符合IPC标准,长/宽/厚公差分别为±0.03mm/±0.03mm/±0.05mm,贴装兼容性强;
  2. 端电极结构:采用Ni底层+Sn表层镀层(厚度≥5μm),可焊性优异(回流焊260℃下保持10秒无缺陷);
  3. 环保认证:通过RoHS 2.0(无铅、无镉、无汞)、REACH SVHC管控,满足欧盟环保要求;
  4. 机械强度:耐弯曲(半径5mm,5次弯曲)后容值变化≤±10%;耐振动(10~2000Hz,1.5g加速度)无性能衰减。

四、温度特性与可靠性

X7R是MLCC中中温稳定型温度系数,该产品可靠性表现如下:

  1. 温度稳定性:-55℃~+125℃范围内,容值变化≤±15%(相对于25℃基准),损耗tanδ变化≤2倍;
  2. 高温寿命:125℃、50V DC条件下,1000小时后容值变化≤±10%,漏电流≤初始值2倍;
  3. 高湿可靠性:85℃/85%RH环境下,50V DC测试1000小时无明显性能衰减;
  4. 焊接可靠性:回流焊峰值260±5℃(时间≤10秒)、波峰焊240℃(时间≤3秒)后,无开裂、脱层缺陷。

五、典型应用场景

因小尺寸、中温稳定、50V耐压等特点,该产品广泛应用于:

  1. 便携式消费电子:智能手机、智能手表、TWS耳机的射频(RF)滤波/耦合、电源旁路;
  2. 小型通信设备:Wi-Fi模块、蓝牙模块、IoT传感器节点的信号调理电路;
  3. 低功耗工业控制:小型PLC、智能传感器(温度/压力)的周边滤波;
  4. 车载娱乐系统:非安全关键件的电源滤波(若需汽车级需选AEC-Q200认证款);
  5. 医疗小型设备:便携式血糖仪、血压计的低噪声滤波。

六、选型与应用注意事项

为确保可靠性,应用时需注意:

  1. 电压降额:建议实际工作电压≤40V DC(额定值80%),避免过压击穿;
  2. 温度适配:若环境温度长期超125℃,需更换Y5V或C0G(C0G容值偏小);
  3. 焊接工艺:0201封装需精细贴装设备(如三星SM482),回流焊预热区150180℃(60120秒);
  4. 存储条件:常温干燥(-40℃~+85℃,湿度≤60%RH),存储≤12个月,开封后≤1个月内使用;
  5. 焊盘匹配:PCB焊盘建议0.4mm×0.2mm,避免焊盘过大导致短路或过小导致虚焊。

风华FH作为国内MLCC龙头,该产品产能稳定、性价比高,是小型化设备通用电容的理想选择。

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
