风华FH 0402B121K500NT 多层陶瓷贴片电容(MLCC)产品概述

一、产品基本定位与型号解析

该产品为风华高科(FH品牌) 生产的通用型多层陶瓷贴片电容(MLCC),型号命名遵循行业标准化规则,各部分含义清晰:

  • 0402:英制封装规格(0.04英寸×0.02英寸),对应公制1005(1.0mm×0.5mm);
  • B:风华MLCC通用中高压系列标识;
  • 121:容值代码(前两位“12”为有效数字,第三位“1”为倍率10¹,即12×10¹=120pF);
  • K:容值精度(±10%);
  • 500:额定直流电压(50V);
  • NT:端子类型(镍底层+锡表层,适配SMT焊接)。

产品定位为中低压电路的通用滤波、耦合、去耦元件,重点适配高密度小型化电子设备。

二、核心电气性能参数

1. 容值与精度

标称容值120pF,精度±10%,满足大多数通用电路的容值需求(如电源滤波、音频信号耦合),无需额外高精度校准。

2. 电压与温度特性

  • 额定电压:50V直流电压,支持5V/12V/24V等中低压系统,避免过压损坏;
  • 温度系数(X7R):符合EIA标准,工作温度范围**-55℃+125℃**,容值变化率±15%(相对于25℃)。X7R材料兼具容值稳定性与温度适应性,优于Y5V(-30℃+85℃,容变±20%),适合高低温环境。

3. 损耗与绝缘性能

  • 损耗因子(DF):≤1.0%(1kHz/1Vrms),能量损耗小,适合高频滤波;
  • 绝缘电阻:≥10⁴MΩ(25℃/10V),绝缘性能可靠,无明显漏电风险。

三、封装与物理特性

1. 尺寸与厚度

  • 封装:英制0402 → 公制1005(1.0mm±0.1mm×0.5mm±0.1mm);
  • 厚度:典型值0.5mm±0.05mm(具体以 datasheet 批次参数为准)。

2. 机械与焊接性能

  • 端子结构:镍锡镀层(NT),回流焊兼容性好,焊接后附着力强;
  • 抗振动/冲击:符合IPC-J-STD-001标准(振动10g~2000Hz,冲击1500g/0.5ms),适合批量SMT生产。

四、典型应用场景

该产品因小体积、宽温特性、稳定容值,广泛覆盖以下领域:

  1. 消费电子:智能手机、平板电脑的主板(电源去耦、射频滤波、音频耦合);
  2. 通信设备:路由器、交换机的信号处理电路(EMI滤波、信号耦合);
  3. 工业控制:PLC模块、传感器节点(电源稳压、模拟信号滤波);
  4. 汽车电子:车载导航、仪表盘(辅助电源电路,适配车内-40℃~+85℃环境);
  5. 物联网设备:智能家居传感器、穿戴设备(低功耗电路滤波)。

五、产品优势与可靠性

  1. 品牌品质:风华高科为国内MLCC龙头厂商,产品通过ISO9001、IATF16949认证,一致性优于行业平均;
  2. 性能平衡:X7R材料兼顾容值稳定性与温度范围,比C0G(高精度但容值小)更适合通用场景,比Y5V更稳定;
  3. 小型化适配:0402封装节省PCB空间,满足电子设备轻薄化趋势;
  4. 长寿命:多层陶瓷结构抗老化,典型寿命>10000小时(85℃/50V条件下),无电解液泄漏风险(对比电解电容)。

六、使用与选型注意事项

  1. 电压降额:建议实际工作电压不超过额定电压的80%(≤40V),延长寿命;
  2. 焊接工艺:优先回流焊,温度曲线要求:预热150℃180℃(60120秒),峰值温度245℃~260℃(≤10秒),禁止波峰焊(0402封装易开裂);
  3. 储存条件:常温(15℃~35℃)、干燥(湿度≤60%)环境储存,开封后12个月内使用,避免受潮;
  4. 机械应力:PCB弯曲度≤0.5%,焊接后禁止尖锐工具刮碰端子;
  5. 静电防护:MLCC为ESD敏感元件(HBM等级≥2kV),操作时需佩戴防静电手环。

该产品是通用电子电路中替代电解电容、钽电容的高性价比选择,适配多领域小型化设备的核心滤波需求。

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
