顺络SDFL1005Q2R7KTF贴片电感产品概述

一、产品核心身份与定位

顺络SDFL1005Q2R7KTF是一款0402封装小型线绕贴片电感,属于顺络电子常规中高频电感系列。其设计聚焦于低功耗、高密度PCB的电子设备,核心功能覆盖电源滤波、射频匹配、EMI抑制及小型电路储能等场景,是消费电子、物联网、可穿戴设备等领域的常用基础被动元件。

二、关键电性能参数详解

该电感的参数围绕“小尺寸适配、中高频适用、低功耗兼容”设计,各参数的实际意义如下:

  1. 电感量:2.7μH ±10%
    电感量是核心储能参数,2.7μH属于中等容量(介于1μH以下小电感与10μH以上大电感之间),±10%精度满足大多数民用/工业级电路需求(无需超高精度的滤波/匹配场景)。
  2. 额定电流:10mA(直流)
    是电感长期稳定工作的最大直流电流,超过该值会导致磁芯饱和,电感量急剧下降。10mA参数适配低功耗电路(如可穿戴设备、传感器节点),避免大电流波动影响性能。
  3. 直流电阻(DCR):2.4Ω
    由线径、匝数及封装尺寸决定(0402封装线径较细),但10mA电流下功耗仅为I²R=0.24mW,几乎不影响低功耗电路总功耗。
  4. 品质因数(Q值):20@10MHz
    Q值=电感储能/绕组损耗,是衡量“效率”的关键指标。20@10MHz属于中高频电感优秀水平,说明其在10MHz附近损耗低,适合射频前端、中频滤波等对损耗敏感的电路。
  5. 自谐振频率(SRF):28MHz
    电感固有谐振频率(电感量+寄生电容决定),超过该频率后电感表现为容性(失去电感特性)。实际使用频率建议控制在20MHz以下(留8MHz余量),避免谐振影响电路性能。

三、封装与物理特性

  1. 0402封装(英制尺寸:1.0mm×0.5mm)
    超小尺寸适配高密度PCB设计,支持手机、蓝牙耳机、智能手环等“微型化”设备的电路布局,是当前消费电子主流小型封装之一。
  2. 贴片式结构
    兼容自动化SMT生产线,焊接可靠性高(符合IPC-A-610标准),适合大规模量产。
  3. 磁芯与绕组材质
    采用铁氧体磁芯(适配中高频)+ 铜绕组,兼顾电感量稳定性与高频损耗控制,避免金属磁芯在高频下的涡流损耗。

四、典型应用场景

结合参数特性,核心应用集中在低功耗、中高频、小型化设备:

  1. 可穿戴设备:智能手环/手表的电源滤波(抑制纹波)、射频前端匹配(2.4G蓝牙/WiFi电路);
  2. 物联网传感器节点:温湿度/运动传感器的EMI抑制(减少电磁干扰)、储能电路(配合电容稳定电压);
  3. 小型通信模块:2.4G/5G无线模块的中频滤波、信号匹配电路;
  4. 消费电子配件:蓝牙耳机、遥控器、智能门锁的信号处理电路(滤波杂波)。

五、品牌与可靠性背书

  1. 顺络电子(Sunlord):国内被动元器件龙头,专注电感研发20余年,产品覆盖全球消费电子、汽车电子、通信领域;
  2. 环保与认证:符合RoHS 2.0、REACH等国际环保标准,批量产品一致性好;
  3. 可靠性测试:经过高低温循环(-40℃+85℃)、湿度(85%RH)、振动(102000Hz)测试,确保长期稳定性。

六、选型与使用注意事项

  1. 电流限制:实际直流电流≤10mA,脉冲电流峰值也需控制在10mA以内(避免磁饱和);
  2. 频率限制:工作频率≤20MHz(远离SRF28MHz),高频应用需选更高SRF的电感;
  3. PCB布局:参考顺络 datasheet的pad尺寸设计,避免pad过小导致焊接不良;
  4. 功耗核算:多路并联/串联时需累计DCR功耗,避免影响系统效率。

该电感是“小而精”的中高频选型,参数均衡且适配低功耗小型设备需求,是消费电子、物联网领域的高性价比方案。

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
