FM31N472J101PXG 贴片多层陶瓷电容(MLCC)产品概述

一、产品核心身份与定位

FM31N472J101PXG是PSA信昌电陶推出的一款高频稳定型贴片多层陶瓷电容(MLCC),针对精密电子电路对容值稳定性、高频损耗及电压耐受的需求设计。其核心参数明确:容值4.7nF、精度±5%、额定电压100V、温度系数C0G(NP0)、封装1206(英制,公制3216),属于中小容值、中压、高稳定MLCC范畴,广泛适配消费电子、工业控制、汽车电子等领域的高频/精密电路。

二、关键参数全解析

  1. 容值与精度:标称容值4.7nF(即472pF,行业3位数字标识:前两位“47”为有效数字,第三位“2”表示10²倍,47×10²=4700pF=4.7nF),精度±5%(对应行业“J”档标识),满足绝大多数精密电路对容值一致性的要求。
  2. 额定电压:直流额定电压100V,是核心电压耐受指标,实际应用需遵循降额原则(建议工作电压≤80V直流),避免过压失效。
  3. 温度系数:C0G(IEC标准,国内称NP0)属于0类温度系数,容值随温度变化极小——典型值±30ppm/℃(温度每变1℃,容值变化≤30×10⁻⁶),远优于X7R(±1500ppm/℃)、Y5V(±22000ppm/℃)等材质。
  4. 封装尺寸:1206英制封装(公制3216),尺寸3.2mm×1.6mm×1.0mm(典型厚度),兼顾小体积与焊接可靠性,适配主流SMT生产线。
  5. 工艺特性:采用PSA精密叠层工艺,电极均匀性好,100MHz下ESR(等效串联电阻)≤10mΩ,DF(损耗角正切)≤0.15%,高频损耗极低。

三、核心技术特性

  1. 极致温度稳定性:-55℃~125℃宽温范围内,容值变化率≤0.03%,可稳定适配极端环境(如工业户外传感器、汽车发动机舱电路)。
  2. 高频低损耗:低ESR、低DF特性使其在100MHz~1GHz频段仍保持优异滤波与匹配性能,适合射频前端、振荡电路。
  3. 无直流偏置效应:区别于X7R/Y5V材质,不存在“直流偏置导致容值下降”问题(X7R额定电压下容值可能降30%以上),适合电源滤波、信号耦合。
  4. 焊接兼容性:镍锡(Ni/Sn)电极适配回流焊(峰值245℃±5℃,时间≤10s)、波峰焊,焊接良率高,无“立碑”“虚焊”问题。

四、典型应用场景

  1. 高频振荡电路:作为石英晶体振荡器(XO)、压控振荡器(VCO)的负载电容,保证振荡频率精度(如通信基站时钟模块)。
  2. 射频前端匹配:用于Wi-Fi 6、蓝牙5.0模块的天线匹配网络、滤波器,提升信号传输效率。
  3. 精密模拟电路:运放反馈网络、信号调理电路的耦合电容,±5%精度满足增益/带宽一致性要求。
  4. 中压电源滤波:12V~48V电源模块的高频滤波,100V额定电压满足降额需求,抑制纹波噪声。
  5. 汽车电子辅助电路:车身控制模块(BCM)信号滤波、胎压监测(TPMS)天线匹配,适配-40℃~85℃汽车环境。
  6. 工业控制接口:PLC I/O接口滤波,抗电磁干扰(EMI),保证信号传输可靠性。

五、可靠性与质量保障

  1. 认证体系:通过ISO9001、IATF16949(汽车级)认证,部分批次符合AEC-Q200标准。
  2. 可靠性测试:
    • 高温存储:125℃×1000h,容值变化≤±2%,DF变化≤±0.05%;
    • 温度循环:-55℃~125℃×1000次,无开路/短路,容值变化≤±1%;
    • 湿度负荷:85℃/85%RH×1000h,绝缘电阻≥10⁹Ω(50V直流)。
  3. 包装存储:7英寸卷盘(10000pcs/盘),存储条件25℃±5℃、湿度≤60%RH,开封后1个月内使用完毕。

六、选型与使用注意事项

  1. 电压降额:直流工作电压≤80V,交流有效值≤80V,避免过压。
  2. 温度匹配:确认环境温度在-55℃125℃范围内,超出需换对应材质(如X5R适用于-40℃85℃)。
  3. 静电防护:ESD等级1kV~2kV,操作需防静电手环、工作台,避免击穿。
  4. 焊接控制:回流焊峰值≤260℃,时间≤10s;波峰焊≤250℃,避免陶瓷开裂。
  5. 试产验证:首次使用前小批量试产,验证焊接良率与电路性能。

FM31N472J101PXG凭借C0G材质的高稳定性、高频低损耗及1206封装的灵活性,成为精密电子电路中替代进口的高性价比选择,广泛适配多领域应用需求。

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
