FN18N101J500PSG 贴片多层陶瓷电容(MLCC)产品概述

一、产品基础定位与核心属性

FN18N101J500PSG是PSA信昌电陶推出的一款高性能贴片多层陶瓷电容(MLCC),属于高频稳定型电容范畴。其核心定位为满足对容值稳定性、温度适应性要求较高的电子电路设计,尤其适用于射频、精密模拟及宽温环境下的应用场景。产品以紧凑的0603封装实现了100pF容值的稳定输出,兼顾小型化与性能可靠性,是工业级、消费电子领域的常用基础元件。

二、关键电气性能参数深度解析

该电容的电气参数直接决定了其应用边界,核心参数及优势如下:

1. 容值与精度

  • 标称容值:100pF(对应电容代码“101”,即10×10¹=100pF),属于射频、滤波电路的常用容值范围;
  • 精度等级:±5%(代码“J”),为工业级通用精度,可满足多数精密电路的匹配需求,无需额外校准,适配批量生产的一致性要求。

2. 额定电压与耐压特性

  • 额定直流电压:50V,可稳定工作在常规电子设备的电源、信号线路中(实际耐压值通常高于额定值,具备1.5倍以上安全余量),避免过压击穿风险;
  • 交流电压适配:支持低频交流电路(<1kHz)的滤波应用,电压峰值不超过50V即可稳定工作。

3. 温度系数与稳定性

  • 温度系数:C0G(NP0),这是该电容的核心优势——容值随温度、电压变化极小。具体而言:
    • 温度范围:-55℃至+125℃(工业级宽温);
    • 容值变化率:≤±30ppm/℃(即1℃变化,容值变化≤30×10⁻⁶×100pF=3fF);
    • 无直流偏置效应:容值不随工作电压变化(区别于X7R等材质的“电压依赖性”),适合高频信号传输与精密匹配。

三、物理封装与工艺可靠性

1. 封装规格

  • 封装形式:0603(英制代码,对应公制尺寸1.6mm×0.8mm×0.5mm),属于小型化贴片封装,适配高密度SMT生产线,可有效节省PCB布局空间,适合便携设备(如手机、智能手表)、小型模块(如蓝牙模块)设计。

2. 工艺与可靠性

  • 多层陶瓷结构:采用“叠层印刷+高温烧结”工艺,形成致密陶瓷介质层与金属电极层,确保容值一致性(批量生产偏差≤±5%)与长期稳定性(无老化效应);
  • 环保兼容性:符合RoHS 2.0、REACH标准,端电极采用无铅镍/锡镀层,适配绿色电子产品设计;
  • 焊接可靠性:支持回流焊、波峰焊工艺,焊接后附着力强,抗机械应力性能优异(可通过跌落测试、振动测试,满足GJB等军标/工标要求)。

四、品牌与典型应用场景

1. 品牌优势

PSA信昌电陶是国内陶瓷电容领域的资深厂商,拥有10余年MLCC研发与生产经验,产品覆盖消费电子、通信、工业控制、汽车电子等多领域。该品牌的C0G系列电容以**“容值一致性好、温度稳定性高、成本可控”**为核心竞争力,适合批量采购与长期稳定供货,是众多OEM/ODM厂商的优先选择。

2. 典型应用场景

  • 射频电路(RF):手机、路由器的天线匹配、滤波电路,利用C0G的低损耗(tanδ≤0.001@1kHz)提升信号传输质量;
  • 精密模拟电路:医疗设备(如心电图机)的信号采集、音频电路的滤波,避免容值变化导致的信号失真;
  • 宽温环境应用:汽车电子(-40℃至+85℃)、工业控制设备(如PLC模块),稳定应对温度波动;
  • 振荡电路:晶体振荡器的负载电容,确保振荡频率稳定(温漂≤1ppm/℃),减少频率偏移。

五、产品选型与使用注意事项

  1. 电压匹配:电路工作电压需低于50V额定值,避免过压导致电容击穿;
  2. 精度升级:若需更高精度(如±1%),需选择“B”级精度的同系列产品;
  3. 封装兼容性:0603封装需匹配PCB焊盘尺寸(建议焊盘长度1.01.2mm,宽度0.60.8mm),确保焊接可靠性;
  4. 机械应力防护:陶瓷材质易碎,避免过度弯折PCB或施加机械压力,防止电容开裂。

该产品以高稳定性、小型化、成本优势,成为高频精密电路设计的核心元件之一,可有效提升电路性能的一致性与可靠性。

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.
