FM18X472K101PSG 贴片陶瓷电容(MLCC)产品概述

一、产品基本身份与核心定位

FM18X472K101PSG是PSA信昌电陶推出的通用型多层陶瓷贴片电容(MLCC),采用0603英制封装,针对中低压、通用精度场景设计,平衡了性能稳定性与成本控制,广泛适用于消费电子、工业控制、小型便携设备等领域的电源滤波、信号耦合等基础电路。

二、关键性能参数详细解析

2.1 容值与精度

容值为4.7nF(对应3位编码“472”:47×10²pF=4700pF=4.7nF),精度等级为**±10%**,满足大多数通用电路对电容值偏差的要求,无需额外校准即可适配常规设计。

2.2 额定电压

额定直流电压为100V,可覆盖12V75V的工作电压范围(建议留20%50%余量以提升可靠性),适用于非高压电源系统的滤波、去耦场景。

2.3 温度系数

采用X7R介质(MLCC主流介质之一):

  • 温度适用范围:-55℃~+125℃;
  • 容值变化率:工作温度范围内≤±15%,远优于Y5V等低成本介质,同时比NPO等温度稳定型介质成本更低。

2.4 封装规格

封装为0603英制(公制对应0201),具体尺寸:

  • 长度:1.6±0.15mm;
  • 宽度:0.8±0.15mm;
  • 厚度:约0.8±0.1mm(典型值); 适配表面贴装技术(SMT),支持自动化贴装,适合高密度PCB布局。

三、封装与工艺特性

FM18X472K101PSG采用多层陶瓷叠层工艺:

  1. 叠层结构:多层陶瓷介质与电极交替叠层,提升容值密度,实现小封装下的4.7nF容值;
  2. 电极材料:采用镍基无铅电极,降低等效串联电阻(ESR)与等效串联电感(ESL),适合高频信号传输;
  3. 环保认证:符合RoHS 2.0指令,不含铅、镉、汞等有害物质,满足全球电子产业环保要求。

四、典型应用场景

该产品因体积小、性能稳定,广泛应用于以下场景:

  1. 电源电路:低压直流电源模块的输出滤波、旁路电容(如12V/24V电源纹波抑制);
  2. 信号链路:模拟音频耦合、数字电路(单片机、FPGA)IO口去耦;
  3. 小型便携设备:智能手机、智能手表、蓝牙耳机的高密度PCB布局;
  4. 工业控制:低电压控制板信号滤波、储能(适配-40℃~85℃工业环境);
  5. 消费电子:电视、机顶盒、路由器的电源滤波与信号处理。

五、品牌与可靠性优势

PSA信昌电陶作为国内MLCC成熟厂商,产品具备:

  1. 认证背书:通过ISO9001、ISO14001认证,部分批次符合AEC-Q200汽车级标准;
  2. 批次一致性:容值、温度特性波动小,便于批量生产一致性控制;
  3. 长期稳定性:X7R介质经优化,长期使用容值衰减率低,提升设备寿命。

六、选型与应用注意事项

  1. 电压余量:实际工作电压≤75V(留25%余量),避免过压击穿;
  2. 温度适配:超出-55℃~125℃需换X8R等高温介质;
  3. 焊接工艺:回流焊峰值温度≤240℃,避免陶瓷开裂;
  4. 静电防护:生产/存储需防静电,防止击穿;
  5. 容值稳定:X7R容值随电压/频率轻微变化,射频电路需换NPO介质。

该产品是通用电子电路中“小体积、稳性能、低成本”的典型选择,适配多数常规设计需求。

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
