Sunlord MWSD1608FE220KT 绕线片式功率电感产品概述

一、产品定位与系列背景

MWSD1608FE220KT是顺络电子(Sunlord)MWSD系列中的小型化绕线片式功率电感,针对便携电子、物联网终端等对尺寸、功耗敏感的场景设计。顺络作为国内电感行业龙头,该系列产品兼顾电气性能与紧凑封装,是中低端消费电子、工业小型电路的高性价比选择。

二、核心电气参数详解

1. 电感值与精度

标称电感值为22μH,精度±10%(实际范围19.8μH~24.2μH)。该精度覆盖绝大多数普通电路的设计需求,既保证批量生产的一致性,又无需额外高精度筛选成本,适合对电感量要求不苛刻的电源、滤波电路。

2. 额定电流

连续工作额定电流为200mA,指在规定温度下(通常25℃),电感允许的最大连续直流电流——此时电感温升不超过安全阈值(行业标准≤40℃)。该规格适配小功率电源(如5V转3.3V/1.8V的DC-DC降压模块)的储能需求。

3. 直流电阻(DCR)

线圈本身的直流电阻为2.8Ω,低DCR直接降低工作损耗:在200mA电流下,损耗仅为0.112W(I²R公式),有助于提升电路效率,尤其适合便携设备的低功耗设计。

4. 结构类型

采用绕线片式结构,相比叠层片式电感,绕线设计具有更高Q值(品质因数)和更低交流损耗,在高频(100kHz~1MHz)应用中性能更优,同时支持相同封装下更大的电流承载能力。

三、封装与物理规格

1. 封装尺寸

采用0603英制封装(对应公制1608),典型尺寸为:

  • 长:1.6mm±0.2mm
  • 宽:0.8mm±0.2mm
  • 高:0.8mm±0.2mm

紧凑尺寸适配高密度PCB布局,满足智能手环、蓝牙耳机等小型设备的空间限制。

2. 封装材料

外壳采用耐高温树脂材料,可承受回流焊温度(符合IPC/J-STD-020标准),同时具备良好的机械强度和耐候性,能应对振动、冲击等环境挑战。

四、关键性能特点

  1. 宽温适应性:工作温度范围为-40℃~+85℃(部分批次可扩展至+125℃),覆盖消费电子(常温)、工业小型电路(宽温)的使用场景;
  2. 低EMI干扰:绕线结构优化磁场分布,减少电磁辐射,适合蓝牙、WiFi等对EMI敏感的通信电路;
  3. 长期稳定性:顺络采用优质铜线(漆包线)和封装材料,电感值随时间、温度变化极小,保证电路长期可靠性。

五、典型应用场景

1. 便携式消费电子

  • 智能手机/平板:PMIC电源管理模块的储能电感;
  • 蓝牙耳机/智能手表:充电电路、传感器供电滤波;
  • 便携音箱:音频放大电路的辅助电感。

2. 物联网终端

  • 智能家居传感器(温湿度、人体感应):低功耗供电电路;
  • 智能门锁:控制电路的电源滤波;
  • 可穿戴设备:心率/血氧传感器的匹配电感。

3. 小型通信设备

  • WiFi 6模块、蓝牙5.0模块:电源滤波与射频匹配;
  • 微型路由器:DC-DC降压电路的储能电感。

4. 工业小型电路

  • 微型PLC的I/O接口电路;
  • 小型电机驱动的辅助电感(如微型步进电机)。

六、可靠性与质量保障

顺络对该产品实施全流程质量管控:

  • 符合RoHS 2.0、REACH等环保标准,无有害物质;
  • 通过可靠性测试:振动(102000Hz,1.5G)、冲击(1000m/s²,6ms)、温度循环(-40℃+85℃,500次);
  • 批量供货稳定:年产能充足,支持客户量产需求,同时提供样品测试与技术支持。

MWSD1608FE220KT凭借“小尺寸+低损耗+高可靠性”的组合优势,成为小型化电子设备的主流功率电感选择之一。

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
