FS18B105K6R3PBG 贴片多层陶瓷电容(MLCC)产品概述

一、产品定位与核心价值

FS18B105K6R3PBG是PSA信昌电陶推出的通用型中低电压MLCC,针对常规精度、小封装需求的电子电路设计,兼顾性能稳定性与成本控制,是消费电子、小型家电等领域的高性价比基础元件。其核心价值在于:通过X5R介质工艺平衡温度稳定性与容值密度,适配0603小封装实现电路高密度集成,满足批量生产的可靠性要求。

二、关键参数深度解析

1. 容值与精度

标称容值1μF(代码“105”,即10×10⁵pF),精度±10%(代码“K”)。该精度满足多数常规电路(如电源滤波、信号耦合)的偏差要求,无需额外匹配高精度元件,降低设计与物料成本。

2. 额定电压

额定直流电压6.3V(代码“6R3”),适用于3.3V、5V等低电压供电系统,避免过压击穿风险;同时满足电路对滤波、耦合的电压裕量需求,无需额外降额设计(若工作电压低于6V可直接使用)。

3. 温度系数与介质

采用X5R陶瓷介质,温度适用范围为**-55℃至+85℃**,容值变化率≤±15%。相较于Y5V介质(容值变化±20%)更稳定,适合温度波动不大的工作环境;相较于NPO介质(高频稳定但容值小),更易实现1μF级大容量,适配中低频电路需求。

4. 封装尺寸

0603英制封装(公制1608,1.6mm×0.8mm),典型厚度0.8mm。适配自动化表面贴装工艺,支持高密度电路板设计,符合智能手机、智能穿戴等小型化设备的发展趋势。

三、封装特性与可靠性

FS18B105K6R3PBG的0603封装具备以下可靠性优势:

  • 焊接兼容性:符合IPC标准的镍锡电极设计,兼容无铅回流焊、波峰焊工艺,焊接后无虚焊、脱焊风险,适合批量生产;
  • 机械强度:多层陶瓷结构结合紧凑封装,耐振动(10G~2000Hz)、抗冲击性能优异,可承受电子设备日常使用中的机械应力;
  • 电气性能:低等效串联电阻(ESR≤10mΩ@1kHz)、低等效串联电感(ESL≤0.5nH),高频响应快,适合电源滤波、信号耦合等场景;
  • 环保合规:符合RoHS 2.0、REACH标准,不含铅、镉等有害物质,满足绿色电子设计要求。

四、典型应用场景

FS18B105K6R3PBG的性能适配多种常规电路,典型应用包括:

  1. 消费电子:智能手机/平板的电源滤波(电池供电、USB接口)、音频信号耦合(耳机接口、扬声器驱动);
  2. 小型家电:遥控器、智能插座、小型加湿器控制板的电源滤波、按键电路耦合;
  3. 工业控制模块:小型PLC、传感器节点的低电压供电滤波、信号隔离耦合;
  4. 车载辅助电路:车载USB充电模块、仪表盘背光驱动的辅助滤波(需确认工作温度在X5R范围内)。

五、PSA信昌电陶品牌优势

作为国内MLCC核心供应商,FS18B105K6R3PBG依托PSA品牌具备:

  • 产能稳定:自动化生产线年产能充足,可满足中小批量至大规模采购需求;
  • 质量管控:全流程检测(容值、耐压、温度特性),不良率≤0.1%,符合AEC-Q200(汽车级)基础要求;
  • 技术支持:提供电路设计参考、样品测试服务,帮助客户快速完成产品验证;
  • 成本优势:本地化供应链降低成本,相较于进口品牌价格竞争力显著,适合性价比导向的客户。

该产品通过平衡性能、成本与可靠性,成为常规电子电路中替代进口MLCC的优质选择。

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
