SDCL0603Q5N1BT02B03是顺络电子(Sunlord)推出的高频小功率叠层贴片电感,属于SDCL系列核心产品。其主打超小型化、低功耗、高可靠性,针对便携式电子设备的高密度集成需求设计,适配2.4GHz/5GHz等主流射频频段,是蓝牙、WiFi、物联网(IoT)等场景的优选组件。
该电感的关键参数直接决定了其应用边界,需结合场景重点关注:
电感值为5.1nH,采用顺络成熟的叠层陶瓷工艺实现精准控制,电感偏差符合工业级标准(通常±5%或±10%,具体需参考 datasheet),可满足射频电路中匹配网络、滤波电路对电感量的精确要求。
额定电流为350mA,是电感在不发生磁饱和、性能不下降的最大直流承载电流。该参数适配多数便携式设备的工作电流(如蓝牙模块、低功耗WiFi模块的电流通常在50~300mA),若电流超过阈值,电感值会急剧下降,导致电路性能失效。
DCR为400mΩ,属于同封装同电感值中的较低水平。低DCR可显著降低电感自身功耗(公式:(P=I^2R)),例如350mA工作时功耗仅约0.05W,能有效减少发热、延长电池供电设备的续航时间。
Q值为13@500MHz,反映电感储能与损耗的比值。Q值越高,电感在射频频段的信号损耗越小,信号完整性越好——该参数满足蓝牙、WiFi等射频前端的滤波、谐振电路需求,避免信号衰减过大。
自谐振频率为5.9GHz,是电感的电感特性与寄生电容特性抵消的频率。当工作频率低于SRF时,电感保持电感特性;高于SRF时则表现为电容特性。5.9GHz的SRF覆盖了当前主流射频频段(2.4GHz蓝牙/WiFi、5GHz WiFi等),可避免在工作频段内谐振导致性能失效。
采用0201封装(英制,对应公制0603,尺寸约0.6mm×0.3mm×0.3mm),是当前贴片电感的最小封装之一,可大幅降低PCB占用面积,适配智能手机、智能手表等小型化设备的高密度贴装。
该电感的参数特性使其在以下场景中表现突出:
综上,SDCL0603Q5N1BT02B03是一款专为高频小功率射频场景设计的高性价比叠层电感,其参数平衡了小型化、低功耗与可靠性,是便携式电子设备升级的理想组件。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
