SDCL0603Q1N5ST02B03是顺络电子(Sunlord)推出的高频贴片叠层电感,型号中“0603”对应公制封装尺寸(长0.6mm×宽0.3mm),“1N5”代表标称电感值1.5nH。产品定位为小型化高频电路的核心元件,适配对体积、高频性能要求严格的电子设备,属于顺络叠层电感系列的主流型号之一。
标称电感值为1.5nH,采用叠层陶瓷工艺制造,电感值一致性优于±5%(顺络叠层电感典型精度)。该工艺可有效抑制高频下电感值的漂移,在-40℃~+125℃宽温范围内保持性能稳定,适合对电感精度要求较高的射频匹配场景。
额定电流定义为电感温度升高不超过40℃的最大连续工作电流,600mA的数值可满足中低功耗射频电路的需求(如蓝牙5.3、WiFi6模块的发射端)。实际设计中建议按70%额定电流降额使用,进一步提升长期可靠性。
直流电阻仅120mΩ,远低于同电感值绕线电感的内阻(通常200mΩ以上)。低DCR特性可有效降低功率损耗,减少电路热耗散,尤其适合对效率敏感的射频前端电路,避免因内阻发热影响设备稳定性。
在500MHz频率下Q值为13,Q值反映电感储能能力与损耗的比值(Q=2πfL/R)。该Q值在500MHz频段表现优异,可满足射频匹配网络、带通滤波电路的低损耗需求,减少信号衰减。
自谐振频率高达15GHz,远高于主流高频应用频段(如5G sub-6G最高6GHz、WiFi6最高7.125GHz)。在工作频率下,电感不会发生谐振(谐振时电感特性转为电容性),可保证射频电路的阻抗匹配精度与信号完整性,避免因谐振导致的性能突变。
采用0201封装(英制代码,对应公制0603),尺寸为0.6mm×0.3mm×0.3mm(长×宽×高),是当前贴片电感中最小的封装之一。该尺寸可大幅减少PCB占用面积,适配智能手机、TWS耳机等轻薄化设备的高密度布局需求。
叠层陶瓷工艺具有三大核心优势:
该产品凭借高频性能、小型化与可靠性优势,成为高频小电感市场的主流选择,广泛应用于各类便携电子与通信设备。

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.
