顺络MCL2012SR47MT叠层贴片电感产品概述

一、产品基本定位与封装规格

顺络MCL2012SR47MT是一款专为小型化电子设备设计的叠层贴片电感,隶属于顺络电子MCL2012系列,采用英制0805封装(对应公制2012尺寸),是消费电子、通信及工业控制领域常用的基础电感元件。

该产品封装尺寸符合行业标准:长度L=2.0±0.2mm,宽度W=1.2±0.2mm,厚度T=0.8±0.2mm,体积紧凑,可直接适配自动化贴片生产线,满足高密度电路设计的小型化需求。核心设计为多层陶瓷介质与内电极叠合烧结的叠层结构,相比绕线电感具有体积更小、一致性更好、耐振动性强等优势,适合批量生产与稳定应用。

二、核心电气参数深度解析

MCL2012SR47MT的电气参数经过优化,匹配中低功率、中高频场景的应用需求,关键参数如下:

  1. 电感值与精度:标称电感值470nH(0.47μH),精度±20%,符合叠层电感常规精度等级,能满足多数滤波、匹配电路的电感值要求;
  2. 额定电流:额定电流(Ir)550mA,指电感在工作温度范围内(-55℃~+125℃),电感值变化不超过±10%时的最大持续工作电流,可支撑中低功率电路稳定运行;
  3. 直流电阻(DCR):典型DCR 180mΩ,属于低损耗设计——小DCR减少电感自身直流损耗,降低电路发热,提升电源转换效率;
  4. 自谐振频率(SRF):自谐振频率125MHz,是电感固有谐振点(此时呈容性)。实际应用需保证电路工作频率低于SRF(建议≤40MHz),以维持感性特性,适配蓝牙、WiFi等2.4GHz以下射频场景。

三、典型应用场景适配

MCL2012SR47MT的参数特性使其广泛适配以下场景:

  1. 射频通信模块:蓝牙4.0/5.0、WiFi 2.4G频段模块的滤波/匹配电感,利用125MHz SRF特性保持中高频感性;
  2. 电源滤波电路:DC-DC降压/升压转换器的输出滤波电感,550mA额定电流支撑手机、平板等低功率电源;
  3. 消费电子终端:智能手机、智能手表、平板电脑的信号滤波、电源纹波抑制;
  4. 汽车辅助电路:车载蓝牙、胎压监测(TPMS)的射频匹配电感,宽温范围(-55℃~+125℃)满足汽车级要求;
  5. 物联网设备:低功耗物联网节点的射频前端滤波,适配小体积、低损耗需求。

四、性能优势与可靠性保障

作为顺络电子主流产品,MCL2012SR47MT具备以下优势:

  1. 小型化与一致性:叠层结构实现体积最小化,批量生产一致性好,避免绕线电感的参数离散性问题;
  2. 低损耗与高效能:180mΩ低DCR减少直流损耗,配合550mA额定电流,适合对效率要求高的电源电路;
  3. 宽温与环保认证:工作温度覆盖-55℃~+125℃,通过RoHS、REACH认证,无铅焊接兼容,耐回流焊性能优异;
  4. 品牌背书:顺络作为国内电感龙头,产品经通信、消费电子、汽车等领域广泛验证,可靠性有保障。

五、选型与使用注意事项

设计与使用时需注意:

  1. 频率匹配:电路工作频率需≤40MHz(低于SRF的1/3),避免谐振点附近使用导致容性;
  2. 电流余量:实际工作电流建议≤440mA(留20%余量),防止过热导致参数漂移;
  3. 封装适配:0805封装需匹配PCB焊盘(长度2.53.0mm,宽度1.52.0mm),避免焊接不良;
  4. 环境要求:存储/使用避免高湿度(≤60%RH)、腐蚀性气体,防止性能下降。

综上,顺络MCL2012SR47MT以其小体积、低损耗、宽温可靠等特点,成为小型化电子设备中滤波、匹配、电源滤波的优选电感元件。

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
