SDCL1005C3N3BTDF 贴片叠层电感产品概述

SDCL1005C3N3BTDF是顺络电子(Sunlord)推出的一款小型化贴片叠层电感,专为高密度、低功耗的射频及数字电路设计,凭借紧凑的0402封装和稳定的高频性能,广泛应用于消费电子、物联网终端等领域。

一、产品基本信息

该电感属于顺络SDCL系列叠层电感,型号各部分含义清晰:

  • SDCL:叠层片式电感系列标识;
  • 1005:公制封装尺寸代码(对应英制0402,实际尺寸为长1.0±0.2mm、宽0.5±0.2mm、厚0.5±0.1mm);
  • 3N3:电感值标识(3.3nH);
  • BTDF:后缀(代表产品规格、精度及包装参数)。

产品采用无铅环保工艺,符合RoHS、REACH等国际标准,适配自动化贴片生产流程。

二、核心性能参数详解

1. 电感值与精度

标称电感值为3.3nH,叠层工艺保证参数一致性,常规精度为±5%(部分批次可提供±1%选项),满足射频电路对电感值的稳定要求。

2. 额定电流与温升

额定电流为300mA,指环境温度25℃下允许的最大连续工作电流(对应温升≤40℃)。若环境温度升高,需按降额曲线调整电流,确保可靠性。

3. 直流电阻(DCR)

DCR典型值为200mΩ,叠层结构减少导体损耗,低DCR可降低电路功耗,适合小电流电源滤波场景。

4. 品质因数(Q值)

在100MHz频率下Q值为8,Q值反映电感储能与损耗比,该参数在射频频段表现优异,可减少信号传输损耗。

5. 自谐振频率(SRF)

自谐振频率为6GHz,工作频率远低于SRF时电感呈感性;超过SRF则因寄生电容变为容性,因此适用于6GHz以下电路。

三、封装与工艺特点

1. 0402小型化封装

超小型0402封装体积仅为常规电感的1/3,可大幅节省PCB空间,适配智能手机、可穿戴设备等高密度设计。

2. 叠层陶瓷工艺

通过多层陶瓷叠层+金属化工艺制造,相比绕线电感优势明显:

  • 一致性好:电感值、DCR等参数离散性小;
  • 无引线:避免引线寄生电感,高频性能更稳定;
  • 抗干扰:陶瓷介质隔离效果佳,减少电磁干扰。

3. 高可靠性设计

  • 耐焊接热:可承受260℃回流焊(持续10秒),适配无铅工艺;
  • 抗振动冲击:满足GB/T 2423.10振动测试(10-2000Hz,2g加速度),适合车载、工业环境。

四、典型应用场景

1. 射频前端电路

适配蓝牙5.0、WiFi 6(2.4GHz/5GHz)、NFC等模块,稳定特性优化信号匹配,减少传输损耗。

2. 电源滤波电路

用于小电流DC-DC、LDO输出滤波,低DCR降低纹波,提升电源效率。

3. 高速数字电路

在DDR4/DDR5内存、CPU供电滤波中,0402封装实现高密度布局,满足高速信号去耦需求。

4. 物联网终端

如智能手环、智能家居传感器,小型化+低功耗特性降低终端体积与能耗,适配批量生产。

五、选型参考建议

  1. 频率匹配:工作频率需低于6GHz,避免电感容性化;
  2. 电流降额:环境温度每升高1℃,最大电流降额0.5%;
  3. 精度需求:常规应用选±5%,射频匹配可选±1%;
  4. 空间适配:空间充足时可考虑0603封装(性能相同,体积更大)。

该电感凭借小型化、高性能及高可靠性,成为消费电子、物联网领域主流选型,可满足多数中高频电路设计需求。

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
