Sunlord MWSD1005FR47JTM01绕线片式电感产品概述

一、产品基本信息

MWSD1005FR47JTM01是顺络电子(Sunlord)推出的绕线片式电感,采用0402(英制)/1005(公制,长1.0mm×宽0.5mm)小型化封装,专为表面贴装工艺设计。
型号解析:

  • “1005”对应封装尺寸(公制代码);
  • “47J”表示电感值470nH(47×10¹nH)、精度±5%(J级精度代码);
  • “TM01”为顺络内部规格标识,匹配绕线工艺与性能参数。

二、核心电气参数解析

该电感的关键性能参数可满足中高频电路的匹配需求,具体如下:

  1. 电感值与精度:标称470nH,精度±5%,批量生产一致性较好,能有效降低电路匹配误差;
  2. 额定电流:350mA(25℃环境下),是允许持续通过的最大直流电流,超额定值会导致绕组发热加剧、电感值下降甚至饱和;
  3. 直流电阻(DCR):660mΩ,为绕组直流损耗电阻,低DCR设计可减少电路功率损耗,提升效率;
  4. 自谐振频率(SRF):380MHz,此频率下电感等效为纯电阻,实际工作频率需远低于SRF(建议≤150MHz),否则感抗会转为容抗,失去电感功能;
  5. 封装尺寸:0402封装体积小巧,适配便携设备的高密度PCB布局。

三、典型应用场景

因绕线工艺带来的高Q值(品质因数)与稳定特性,该电感广泛应用于:

  1. 消费电子:智能手机、平板电脑的WiFi(2.4GHz/5GHz)、蓝牙模块的射频匹配网络,以及无线充电电路的滤波电感;
  2. 无线通信:2.4GHz频段的物联网(IoT)设备、蓝牙5.0/5.1模块的信号滤波与阻抗匹配;
  3. 射频电路:射频放大器、混频器、带通滤波器的电感元件,用于信号耦合与阻抗调整;
  4. 小型电子设备:智能手表、手环的蓝牙通信模块、低功耗无线传感器的射频前端电路。

四、产品优势

顺络作为电感领域领先厂商,该产品具备以下优势:

  1. 小型化适配:0402封装节省PCB空间,满足便携设备“轻薄化”需求;
  2. 性能稳定:绕线工艺避免叠层电感的陶瓷温漂问题,电感值随温度变化小(典型±100ppm/℃),适合宽温环境;
  3. 低损耗设计:660mΩ DCR在同封装绕线电感中处于较低水平,减少电路发热,提升便携设备续航;
  4. 高可靠性:符合RoHS标准,抗振动(IEC 60068-2-6)、耐温(-40℃~+85℃),满足工业/消费级设备要求;
  5. 批量一致性:自动化生产保证参数一致,降低电路批量匹配难度。

五、选型与使用注意事项

为确保性能稳定,需注意:

  1. 电流匹配:工作电流不得超350mA,大电流场景需选更高额定电流的同电感值产品;
  2. 频率匹配:避免工作频率接近380MHz,需高频应用时换SRF≥1GHz的电感;
  3. 焊接工艺:回流焊峰值温度245℃±5℃,时间≤10s,避免高温损坏;
  4. 存储条件:-5℃~+35℃、湿度≤60%环境存储,开封后1个月内使用,防止绕组氧化;
  5. PCB设计:焊盘尺寸建议长0.6mm×宽0.3mm,避免过大焊盘引入寄生电容影响性能。

总结

MWSD1005FR47JTM01是顺络针对中高频射频电路推出的高性能绕线电感,兼具小型化、低损耗、高可靠性等特点,广泛适配消费电子、无线通信等领域。其稳定的电气性能与适配性,能有效满足便携设备与射频模块的设计需求,是电路匹配与滤波环节的可靠选择。

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
