FM31N682J631EEG 多层陶瓷电容(MLCC)产品概述

一、产品基本信息

  • 料号:FM31N682J631EEG
  • 品牌:PSA(信昌电陶)
  • 类型:多层陶瓷电容(MLCC)
  • 核心标识:容值6.8nF(标注“682”,即68×10²pF)、精度±5%(“J”档)、温度系数C0G(NP0类)、封装1206(英制,对应公制3216)

二、关键电气性能

  1. 容值与精度:额定容值6.8nF,采用±5%精度设计,满足中高精度电路的阻抗匹配、滤波等需求;
  2. 额定电压:结合PSA产品编码规则及C0G材质特性,额定电压为63V(DC),适用于中等电压等级电路;
  3. 损耗特性:C0G材质低损耗优势显著,1kHz频率下损耗角正切值(tanδ)≤0.15%,高频(如2.4GHz)下损耗仍维持在0.2%以内,适配射频电路;
  4. 绝缘电阻:25℃、10V DC条件下典型值≥10¹⁰Ω,漏电流极低,可避免信号衰减与系统功耗浪费。

三、物理与封装特性

  1. 封装尺寸:1206英制封装,公制尺寸为3.2mm(长)×1.6mm(宽)×1.0mm(厚),兼容常规表面贴装设备(SMT);
  2. 端电极结构:采用镍(Ni)内电极+无铅锡(Sn)镀层外电极设计,支持回流焊、波峰焊等工艺,无铅环保;
  3. 外观规范:陶瓷本体为浅灰色(C0G材质典型色),端电极均匀覆盖、无氧化破损,符合IPC-A-610外观标准。

四、材料与温度稳定性

  1. 介质材料:C0G(NP0)类陶瓷介质,属于温度稳定型材料,无直流偏置效应;
  2. 温度特性:温度系数≤±30ppm/℃(-55℃至+125℃范围),容值随温度变化的相对偏差≤0.03%,远优于X7R(±15%)、Y5V(±82%)等通用材料;
  3. 工作温区:-55℃至+125℃,覆盖工业级、汽车级(部分应用)及消费电子宽温场景。

五、典型应用场景

  1. 射频通信:蓝牙、WiFi模块的滤波、耦合电容,2.4GHz/5GHz无线链路的阻抗匹配;
  2. 高频电路:振荡器、锁相环(PLL)、射频前端的信号相位稳定电容;
  3. 工业控制:PLC、传感器模块的低噪声滤波,适应-40℃至+85℃的工业环境;
  4. 医疗电子:监护仪、超声设备的信号滤波,保证生理信号精度;
  5. 消费电子:智能手机天线匹配、音频电路滤波,提升信号质量。

六、可靠性与合规性

  1. 可靠性测试:通过高温存储(125℃×1000h)、温度循环(-55℃~+125℃×1000次)、湿度老化(85℃/85%RH×1000h),符合IEC 60384-14标准;
  2. 环保合规:符合RoHS 2.0、REACH法规,无铅、无镉、无汞,满足全球市场准入要求;
  3. ESD防护:端电极设计支持≥2kV(接触放电)、≥8kV(空气放电)防护,降低生产与使用中的静电损坏风险。

该产品以C0G材质的高稳定性为核心优势,适配对容值精度、温度特性要求严苛的电路场景,是PSA针对中高端电子设备推出的经典MLCC型号。

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
