MWSD1608FE4R7KT 绕线片式电感产品概述

一、产品基本信息

MWSD1608FE4R7KT是顺络电子(Sunlord) 推出的绕线片式电感,采用行业通用的0603英制封装(对应公制尺寸1608,即长度1.6mm、宽度0.8mm),型号命名逻辑清晰:

  • “1608”对应公制封装尺寸,适配高密度PCB布局;
  • “4R7”明确标称电感值为4.7μH;
  • “KT”为顺络内部精度/编带标识,结合参数确认精度为±10%。

该产品专为小型化电子设备设计,兼顾体积紧凑性与性能稳定性,是低功耗电路的常用电感元件。

二、核心电气性能参数

关键参数明确,为电路设计提供精准参考:

  1. 电感值与精度:标称4.7μH,误差±10%,满足大多数常规电路对电感值的误差要求;
  2. 额定电流:最大直流额定电流420mA,指电感在该电流下电感值变化不超过±10%(磁芯未饱和),若超过则可能导致电感值骤降、损耗剧增;
  3. 直流电阻(DCR):970mΩ(约0.97Ω),反映绕线铜损,该值在同规格0603绕线电感中处于合理水平,可有效控制功率损耗;
  4. 自谐振频率(SRF):51MHz,即电感与寄生电容谐振的频率(此时电感呈纯阻性),实际应用需注意工作频率≤1/3 SRF(约17MHz),避免谐振影响电路性能。

三、结构与工艺特点

采用陶瓷芯体+高纯度铜线绕制+环氧树脂封装的成熟结构,具备以下优势:

  1. 体积紧凑:0603封装体积仅约1.6×0.8×0.8mm,可大幅缩小产品尺寸,适配可穿戴、物联网等小型设备;
  2. 电感线性度佳:绕线结构相比叠层电感,电感值随电流变化的线性度更高,适合对电感稳定性要求较高的电源电路;
  3. 参数一致性好:顺络成熟的绕线工艺确保批量产品的电感值、DCR、SRF等参数偏差极小,减少电路调试难度;
  4. 抗干扰性可控:绕线结构的寄生电容相对叠层电感更小,在EMI滤波电路中可精准抑制特定频率干扰。

四、典型应用场景

结合参数特性,该电感适用于以下低功率、高密度场景:

  1. 小功率DC-DC转换:如智能手环、物联网传感器的降压/升压电源(最大负载电流≤400mA);
  2. 射频辅助滤波:2.4GHz频段(蓝牙、WiFi)的辅助滤波电路(需确认工作频率与SRF的匹配性);
  3. EMI电磁干扰抑制:蓝牙耳机、智能音箱的电源/信号滤波,减少电磁辐射;
  4. 小型充电模块:USB Type-C低功率充电电路(如5V/0.5A输出)的储能电感。

五、选型与使用注意事项

  1. 电流匹配:应用电路最大负载电流需低于420mA,若需更高电流应选择同封装大电流型号;
  2. 频率适配:工作频率需控制在17MHz以下,高频应用需查看顺络阻抗曲线确认性能;
  3. 焊盘设计:需匹配IPC标准焊盘(长度1.01.2mm、宽度0.60.7mm),避免虚焊或焊接强度不足;
  4. 温度环境:常规工作温度为-40℃~+85℃,高温场景需确认型号温度等级;
  5. 焊接工艺:回流焊峰值温度≤245℃(时间≤10s),避免过热损坏绕线结构。

总结

MWSD1608FE4R7KT作为顺络0603封装绕线电感,以紧凑体积、稳定参数和合理损耗,成为小功率电子设备电源管理、滤波等电路的优选元件,可有效提升电路集成度与性能稳定性。

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
