FM31N562J251EEG 贴片多层陶瓷电容(MLCC)产品概述

一、产品核心身份与定位

FM31N562J251EEG 是PSA信昌电陶推出的一款1206封装高耐压C0G类MLCC,专为需要电容值稳定、低损耗、中高压耐受的精密电子场景设计,属于Class I陶瓷电容范畴,无直流偏置效应,温度特性优异。

二、关键参数与性能指标

该产品核心参数严格对应设计需求,具体如下:

  • 容值与精度:标称容值5.6nF(对应代码“562”,即56×10²pF),精度±5%(J档),在全温度范围内容值漂移极小;
  • 额定电压:直流250V,实际使用需预留安全余量(建议工作电压不超过200V),可满足中高压电路滤波需求;
  • 温度系数:C0G(原NP0),温度系数≤±30ppm/℃,-55℃~125℃范围内容值变化可忽略,无老化效应;
  • 损耗特性:损耗角正切(tanδ)≤0.15%(1kHz/25℃),高频下能量损耗低,适合射频/振荡电路;
  • 额定温度范围:-55℃~125℃,覆盖工业级与汽车级(部分场景)温度需求。

三、封装与物理特性

采用1206英制贴片封装(对应公制3216,即3.2mm×1.6mm×0.8mm),适配常规贴片生产线:

  • 外形:矩形扁平结构,两端为镀镍/锡电极(兼容无铅焊接);
  • 重量:约0.05g/颗,符合小型化电子设备的密度要求;
  • 焊盘设计:电极覆盖封装侧面(端电极),焊接可靠性高,回流焊后不易出现虚焊。

四、材料体系与可靠性优势

作为Class I MLCC,FM31N562J251EEG采用钛酸钡基陶瓷介质,核心优势包括:

  1. 无温度漂移:不同于X7R等Class II电容的容值随温度/电压变化,C0G介质容值稳定,适合精密振荡、定时电路;
  2. 低损耗:高频下(如10MHz)仍保持低损耗,避免信号衰减;
  3. 高可靠性:通过PSA内部多项可靠性测试:
    • 高温存储:125℃×1000h,容值变化≤±0.5%;
    • 温度循环:-55℃~125℃×1000次,无开裂/失效;
    • 回流焊耐热:260℃回流焊3次,电极无脱落;
  4. 环保合规:符合RoHS 2.0、REACH标准,不含铅、镉等有害物质。

五、典型应用场景

该产品因“稳定+耐压+低损耗”特性,广泛用于以下场景:

  1. 高频通信设备:射频前端滤波、GPS模块振荡回路、蓝牙/WiFi信号耦合;
  2. 工业控制电路:PLC(可编程逻辑控制器)的精密信号滤波、传感器接口耦合;
  3. 中高压电源:开关电源的直流滤波、LED驱动电源的EMI抑制;
  4. 医疗电子:监护仪、心电图机的信号调理电路(需稳定容值);
  5. 汽车电子:车载导航的射频部分、车身控制模块的定时电路(低功率场景)。

六、选型与使用注意事项

为确保产品性能与可靠性,需注意以下要点:

  1. 电压余量:实际工作电压需低于额定电压的80%(即≤200V),避免过压击穿;
  2. 焊接工艺:采用无铅回流焊,温度曲线需符合PSA推荐(峰值温度245℃±5℃,回流时间≤60s),禁止手工烙铁直接焊接(易损伤介质);
  3. 存储条件:未开封产品需存于常温(15~35℃)、干燥(湿度≤60%)环境,开封后建议1个月内用完,避免受潮;
  4. 极性问题:MLCC无极性,焊接时无需区分正负极,但需确保电极与焊盘对齐;
  5. 机械应力:贴装时避免过度按压,焊接后避免弯折PCB,防止陶瓷介质开裂。

七、品牌与市场适配性

PSA信昌电陶是国内MLCC领域的主流厂商,产品覆盖从0402到2220封装、Class I到Class II全系列,FM31N562J251EEG作为其C0G高压产品线的核心型号,适配于消费电子、工业、医疗等多领域,可替代进口同类产品(如村田GRM系列),性价比优势明显。

综上,FM31N562J251EEG以“稳定容值、高耐压、低损耗”为核心竞争力,是精密电子电路中替代Class II电容、提升信号质量的可靠选择。

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
