FM21X273K101ECG 多层陶瓷电容器产品概述

一、产品定位与品牌背景

FM21X273K101ECG是信昌电陶(PSA) 推出的通用型多层陶瓷电容器(MLCC),属于PSA主流MLCC产品线,针对中低功率电子设备的滤波、去耦等核心功能设计,兼顾电气稳定性与成本效益,广泛适配消费电子、工业控制等领域的标准化电路需求。

信昌电陶作为国内电陶瓷元器件龙头企业,其MLCC产品以工艺成熟、供应稳定著称,FM系列覆盖0402至1206封装、容值1pF至10μF的全规格段,满足不同场景的选型需求。

二、核心电气参数详解

该产品的核心参数直接决定适用场景,具体如下:

  • 容值:27nF(标注代码“273”,即27×10³pF=27nF),属于中容量MLCC,适配大多数电源滤波、信号耦合需求;
  • 精度:±10%(标注代码“K”),为行业通用精度等级,无需额外校准即可满足非高精度电路要求;
  • 额定电压:100V(标注代码“101”,即10×10¹V=100V),可稳定工作在直流100V或交流峰值≤70.7V的电路中,避免过压击穿;
  • 环保标准:端电极采用无铅锡合金,符合欧盟RoHS 2.0指令,无镉、铅等有害物质。

三、封装与机械特性

产品采用0805封装(英制:0.08英寸×0.05英寸,公制:2.0mm×1.2mm),是电子设备中最常用的表面贴装(SMT)封装之一,具有以下优势:

  • 尺寸紧凑:适配高密度PCB布局,支持小型化电子设备设计;
  • 贴装兼容:焊盘尺寸符合IPC标准,可通过自动化贴片机高效生产,良率≥99.5%(PSA官方数据);
  • 机械强度:叠层结构采用高韧性陶瓷介质,可承受±2mm的PCB弯曲应力(符合JIS C 5102标准),避免焊接或使用中开裂。

四、温度特性与稳定性

该产品采用X7R温度系数,是平衡容值稳定性与温度范围的主流选项,具体特性:

  • 温度范围:-55℃至+125℃(行业X7R标准范围);
  • 容值变化:全温度范围内偏移≤±15%(相对于25℃基准值),远优于Y5V等低成本系数(Y5V变化可达±20%以上);
  • 场景适配:适合温度波动较大的环境(如户外工业设备、汽车电子周边电路),避免电路性能漂移。

五、典型应用场景

结合参数特性,该产品广泛应用于:

  1. 电源滤波:开关电源(SMPS)、DC-DC转换器的输入/输出滤波,去除高频纹波;
  2. 数字电路去耦:CPU、FPGA等核心芯片的电源引脚去耦,抑制电源噪声;
  3. 通信设备:路由器、交换机的射频前端耦合、去耦,保证信号传输质量;
  4. 工业控制:PLC、变频器的辅助电源滤波,提高抗干扰能力;
  5. 消费电子:电视、机顶盒、智能音箱的电源模块,满足小型化与低成本需求。

六、可靠性与环境适应性

PSA对该产品的可靠性设计符合多项行业标准:

  • 寿命:额定电压(100V)、额定温度(85℃)下,平均无故障时间(MTBF)≥10⁶小时;
  • 环境耐受:可承受湿度95%RH(40℃)、振动(10-2000Hz,加速度1.5g)等恶劣环境;
  • 焊接兼容性:支持回流焊、波峰焊工艺,焊接温度峰值260℃(符合IPC-J-STD-020标准)。

七、选型与替代参考

若需扩展或替代,可参考以下方案:

  • 同参数替代:三星CL21B273KAFNNNE、村田GRM188R61C273KA73D;
  • 容值升级:PSA FM21X104K101ECG(0805 100nF ±10% 100V X7R);
  • 精度升级:PSA FM21X273J501ECG(0805 27nF ±5% 50V NPO)。

该产品凭借PSA的供应链优势与稳定性能,成为中低功率电路中替代进口MLCC的高性价比选择。

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
