SDCL0603Q3N9ST02B03是顺络电子(Sunlord)推出的超小型叠层贴片电感,属于公司高频电感系列产品。其封装采用0603公制尺寸(对应英制0201),实际尺寸为0.6mm×0.3mm×0.3mm,体积仅为传统绕线电感的1/3左右,专为高密度PCB布局设计。产品符合RoHS无铅标准,兼容回流焊、波峰焊等主流贴片工艺,可直接用于消费电子、通信设备的批量生产。
该产品的关键参数针对高频、小型化场景优化,具体解析如下:
稳定的低电感值是高频电路的核心需求——3.9nH可精准匹配WiFi6(5GHz)、蓝牙5.2(2.4GHz)等频段的信号路径,避免电感过大导致的信号延迟,同时满足电源滤波的快速响应要求。
额定电流是电感允许的最大持续工作电流,400mA可覆盖TWS蓝牙耳机、智能手环等便携设备的典型工作电流(通常100-300mA),且叠层工艺的磁芯特性可避免电流过载导致的电感饱和(饱和电流约为额定电流的1.2倍)。
低DCR是降低电路损耗的关键——400mA工作电流下,功率损耗仅约48mW,可减少便携设备的热耗,间接提升电池续航(以1000mAh电池为例,每天减少约0.2%的额外损耗)。
Q值反映电感的储能/损耗比,13@500MHz的高Q值意味着在射频频段内信号损耗小,可保证WiFi6的信号传输完整性(减少误码率),同时降低射频前端的功耗。
电感在SRF以下表现为感性,以上转为容性。7.4GHz的谐振点覆盖了5G sub-6GHz(2.6-6GHz)、WiFi6(2.4/5GHz)等主流高频频段,避免在常用场景下发生谐振,保证电路性能稳定。
顺络采用多层陶瓷叠层工艺,相比绕线电感具有明显优势:
该产品的参数特性使其适用于以下场景:
综上,SDCL0603Q3N9ST02B03以“超小型封装+低损耗+宽频特性”为核心优势,是高频便携设备及通信模块的高性价比电感选型,兼顾性能与可靠性。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
