顺络SDFL1005QR39KTF贴片电感产品概述

一、产品基本定位与品牌背景

顺络SDFL1005QR39KTF是顺络电子(Sunlord)推出的0402封装高频小功率贴片电感,属于公司叠层电感系列的核心产品。顺络电子作为国内被动元件龙头企业,专注于片式电感、压敏电阻等产品的研发生产,产品覆盖消费电子、通信、汽车电子等领域,以高一致性、可靠性著称。该型号针对小型化、低功耗高频电路设计,适配便携式设备的紧凑空间需求。

二、核心电气参数深度解析

1. 电感值与精度

标称电感量390nH,精度±10%(实际范围351nH~429nH),满足多数高频电路的谐振、滤波、阻抗匹配需求,尤其适配蓝牙(2.4GHz)、WiFi(2.4/5GHz)等ISM频段的信号调理。

2. 额定电流与直流电阻(DCR)

额定电流15mA(环境25℃下温升≤40℃的最大连续电流),直流电阻600mΩ。两者结合计算,额定电流下功耗仅13.5μW(P=I²R),低功耗特性适配可穿戴、物联网等低功耗场景。

3. 品质因数(Q值)

10MHz下Q值为20,Q值反映电感储能与损耗的比值(Q=2πfL/R),Q值越高损耗越小。20的Q值在同封装同电感量产品中处于上游,可有效降低射频电路信号衰减。

4. 自谐振频率(SRF)

自谐振频率85MHz,电感寄生电容与自身电感形成谐振:85MHz以下呈感性,以上呈容性。设计时需避开该频率附近,防止电感性能突变(如阻抗急剧变化)。

三、封装与物理特性

采用0402英制封装(公制1005,尺寸1.0mm×0.5mm),是小型化设备的常用封装。贴片结构适配SMT自动化生产,焊盘符合IPC标准,焊接可靠性高;小尺寸可缩小PCB面积,提升设备集成度,适合智能手环、蓝牙耳机等紧凑空间应用。

四、典型应用场景

结合参数与封装特性,该电感主要适用于:

  1. 射频前端模块:蓝牙、WiFi、ZigBee模块的滤波、阻抗匹配,利用高Q值降低信号损耗;
  2. 可穿戴设备:智能手表、手环的低功耗射频电路,低DCR+小封装适配轻薄化需求;
  3. 物联网节点:传感器节点的天线匹配,满足低功耗、小型化要求;
  4. 便携式消费电子:MP3、蓝牙耳机的电源滤波与信号调理,稳定电源纹波。

五、品质与可靠性保障

产品符合RoHS 2.0、REACH环保法规,无铅无卤。经过严格可靠性测试:

  • 温度循环:-40℃~+85℃循环1000次,性能无明显变化;
  • 振动测试:10Hz~2000Hz、2g加速度持续2小时,焊接点无脱落;
  • 湿热测试:60℃/90%RH环境1000小时,电感量变化率≤±5%。
    确保复杂环境下的长期稳定性,适用于消费电子、工业控制等领域。

六、选型与替换注意事项

  1. 电感值匹配:替换品实际电感量需在351nH~429nH范围内;
  2. 电流与DCR:额定电流≥15mA,DCR≤600mΩ(避免功耗增加);
  3. 射频性能:10MHz下Q值≥20,SRF≥85MHz(保证高频损耗与谐振特性);
  4. 封装一致性:必须采用0402封装,与PCB焊盘尺寸匹配。

该产品凭借高频性能、小尺寸与可靠性,成为小型化电子设备射频电路的优选电感之一。

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
