FM21N472J101ECG 产品概述

FM21N472J101ECG是PSA信昌电陶推出的一款0805封装多层陶瓷贴片电容(MLCC),专为需要高精度、低损耗、温度稳定的电子电路设计,核心参数覆盖4.7nF容值、±5%精度、100V额定电压及C0G温度系数,广泛适配射频、高速数字、精密模拟等场景。

一、核心参数总览

该型号的关键参数可通过型号编码与公开规格明确,具体如下:

参数项 规格值 编码含义说明 标称容值 4.7nF(472) 47×10²pF=4.7nF 容值精度 ±5%(J) EIA精度代码J对应±5% 额定电压(DC) 100V(101) 10×10¹V=100V 温度系数 C0G(NP0类) 温度补偿型,低漂移 封装尺寸 0805(英制) 2.0mm×1.25mm(公制) 工作温度范围 -55℃~125℃ 符合工业级温度要求 环保标准 RoHS 2.0、REACH 无铅无卤,绿色环保

注:C0G与行业常用的“NP0”为等效温度系数,均指容值随温度、电压变化极小的陶瓷介质。

二、封装与物理特性

0805封装是电子行业应用最广泛的贴片封装之一,FM21N472J101ECG的封装特性如下:

  1. 尺寸紧凑:公制尺寸2.0mm(长)×1.25mm(宽)×1.0mm(厚,典型值),适配高密度PCB布局,支持0.1mm级的贴装精度;
  2. 表面贴装兼容:采用镍钯金(Ni/Pd/Au)或镍锡(Ni/Sn)电极,兼容回流焊、波峰焊工艺,焊接后焊点可靠性高;
  3. 环保设计:符合欧盟RoHS 2.0及REACH法规,不含铅、镉、汞等有害物质,满足绿色电子产品设计要求。

三、电气性能详解

作为C0G介质MLCC,FM21N472J101ECG的电气性能核心优势在于高稳定性、低损耗:

  1. 容值稳定性:温度系数≤±30ppm/℃(25℃为基准),电压系数≤0.02%/V,容值随温度、工作电压变化可忽略,适合精密电路;
  2. 低损耗特性:1kHz/25℃下损耗角正切(DF)≤0.15%,高频下(如100MHz)DF仍保持≤0.2%,有效降低射频电路的信号衰减;
  3. 额定电压可靠性:直流100V额定电压,工作时可承受1.5倍额定电压的短时间过压(如浪涌),满足电源电路的防护需求;
  4. 频率特性:在1GHz以下频段容值变化≤1%,适配高速数字电路(如DDR4/DDR5)的时钟去耦及射频滤波器应用。

四、材料与可靠性验证

PSA信昌电陶采用多层陶瓷叠层工艺制造该产品,材料与可靠性经过严格测试:

  1. 介质材料:采用钛酸钡基稳定陶瓷介质,确保C0G特性的长期一致性,避免老化导致的容值漂移;
  2. 可靠性测试:
    • 温度循环:-55℃~125℃循环1000次,容值变化≤±0.5%;
    • 耐湿性:85℃/85%RH环境下1000小时,容值变化≤±1%;
    • 机械强度:符合JESD22-B104振动测试(10Hz~2000Hz,加速度2g),贴片后抗振动、冲击能力强;
  3. 寿命评估:在额定电压、125℃下,MTBF(平均无故障时间)≥10^6小时,满足工业级产品的长期使用需求。

五、典型应用场景

FM21N472J101ECG因高稳定性与低损耗,广泛应用于以下领域:

  1. 射频通信设备:基站滤波器、射频前端耦合器、无线模块谐振器;
  2. 高速数字电路:服务器、路由器的DDR内存去耦、时钟电路滤波;
  3. 精密模拟电路:运算放大器反馈网络、高精度传感器信号滤波;
  4. 工业控制设备:PLC、变频器的控制电路滤波、电源噪声抑制;
  5. 医疗电子:监护仪、超声设备的低噪声电路(需稳定容值)。

六、选型与品牌优势

  1. 选型适配性:4.7nF是常用滤波容值,100V电压覆盖中压电路(如12V~48V电源的二次滤波),0805封装适配多数PCB设计,无需特殊布局;
  2. 品牌保障:PSA信昌电陶是国内MLCC头部厂商,拥有10余年陶瓷电容研发生产经验,产品通过ISO9001、IATF16949认证,供应能力稳定,交期短于进口品牌;
  3. 成本优势:相比村田、TDK等进口品牌,同规格产品价格更具竞争力,适合批量生产的成本控制需求。

综上,FM21N472J101ECG是一款性能稳定、适配性强的C0G介质MLCC,可满足精密电子设备对高稳定性电容的需求,是射频、高速数字、工业控制等领域的优选方案。

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
