FN15B104K500PKG(PSA信昌电陶0402封装MLCC)产品概述

FN15B104K500PKG是PSA信昌电陶推出的0402封装通用型多层陶瓷电容(MLCC),针对消费电子、工业控制等场景的滤波、耦合需求设计,核心参数平衡了容值密度、温度稳定性与电压耐受能力,是小体积电路设计的常用选型。

一、产品基本定位

该产品属于通用中容值MLCC,区别于高压、高频或高容值的专用型号,重点适配对容值精度要求不苛刻(±10%)、电压需求中等(50V)的常规电路。PSA信昌电陶作为专业陶瓷电容厂商,其产品在自动化贴装兼容性、长期可靠性上具备行业竞争力,符合RoHS无铅标准,可满足多数电子终端的环保要求。

二、核心参数详细解析

1. 容值与精度

标称容值为100nF(10⁴ pF),采用三位数字代码“104”标识(前两位为有效数字,第三位为10的幂次);精度为**±10%**,满足一般电源滤波、信号耦合等场景对容值偏差的要求,无需额外高精度匹配。

2. 电压耐受能力

额定直流电压为50V,可承受短期(1-2秒)1.5倍额定电压(75V)的浪涌冲击,符合MLCC的标准过压耐受规范,适用于低压直流电路的电源设计(如5V/12V系统的滤波)。

3. 温度特性

温度系数为X5R,对应温度范围为**-55℃至+85℃**,在此区间内容值变化率≤±15%。相比NPO(温度系数极低但容值密度低)和Y5V(容值密度高但温度稳定性差),X5R平衡了容值与稳定性,适合多数工业级和消费级环境。

4. 封装规格

采用0402贴片封装(英制代码,对应公制尺寸约1.0mm×0.5mm×0.5mm),无引脚设计,适配自动化贴装设备(如回流焊、波峰焊),可大幅节省PCB布局空间,尤其适合小型化电子终端(如智能手机、智能穿戴)。

三、封装与工艺特点

1. 介质与电极设计

  • 介质材料:采用X5R陶瓷介质,介电常数(εᵣ)约为2000-3000,在0402小体积下实现100nF容值,容值密度优于NPO介质;
  • 电极结构:内层采用镍(Ni)电极,焊端为无铅锡银铜(Sn-Ag-Cu)合金,焊端附着力强,回流焊温度窗口宽(220℃-240℃),贴装良率高。

2. 制造工艺

采用多层陶瓷叠层工艺,将陶瓷介质层与电极层交替叠放后经高温烧结成型,结构紧凑且无电解液泄漏风险,相比电解电容更适合高频场景。

四、典型应用场景

  1. 消费电子:智能手机、平板电脑的DC-DC转换电路输出滤波、音频信号耦合、射频链路匹配;
  2. 工业控制:PLC模块、传感器节点的电源去耦、抗电磁干扰(EMI)滤波;
  3. 车载电子:车载音响、仪表盘电路的低压滤波(环境温度≤85℃场景);
  4. 通信设备:路由器、交换机的电源滤波、高速信号链路的匹配电容。

五、可靠性与环境适应性

  • 温度稳定性:X5R特性确保-55℃至+85℃内性能稳定,无需额外温度补偿;
  • 耐湿性:符合IPC J-STD-020湿度测试标准,焊端无吸潮脱落风险;
  • 长期寿命:额定条件下(25℃、50V)寿命可达10年以上,无老化失效风险;
  • 抗干扰性:陶瓷介质的高频损耗低,适合抑制高频噪声,提升电路EMI性能。

六、选型与替换要点

  1. 同参数替换:需确认封装(0402)、容值(100nF)、精度(±10%)、额定电压(≥50V)、温度系数(X5R或更优,如X7R);
  2. 焊端兼容性:优先选择无铅焊端产品,避免不符合RoHS要求;
  3. 温度场景适配:若应用环境温度超过85℃,需替换为X7R温度系数的型号(如PSA对应X7R的型号),但容值密度可能略有下降。

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
