SDCL0603Q24NHT02B03是顺络电子(Sunlord)推出的高频小型化叠层电感,针对射频(RF)前端、物联网终端、可穿戴设备等低功耗高频场景设计,凭借紧凑的0201封装、稳定的电气特性及成熟的叠层工艺,成为中高频电路匹配、滤波的核心无源器件之一。
该电感定位于中高频低功耗电路,主要覆盖1GHz以下的射频应用领域,典型场景包括:
作为高频电感,其电气参数直接决定射频性能,关键指标如下:
电感值与精度
标称电感值24nH,精度±3%——叠层工艺通过精细的内部电极叠层控制,确保电感值偏差稳定在3%以内,满足射频匹配网络对电感值一致性的严格要求(如5G sub-6GHz频段的阻抗匹配需精准的电感值)。
额定电流与直流电阻(DCR)
额定电流140mA(直流),直流电阻1.6Ω——低DCR设计可显著降低电路功耗(功耗=I²×R),适合电池供电的低功耗设备;额定电流需注意温度降额:环境温度超过85℃时,额定电流需按顺络官方降额曲线降低(如105℃时降额至100mA左右),避免电感过热饱和。
品质因数(Q值)与自谐振频率(SRF)
紧凑封装
采用0201英制封装(对应公制0603,尺寸0.6mm×0.3mm×0.3mm),是目前小型化电感的主流封装之一,可显著缩小电路体积,适配智能手机、蓝牙耳机等高密度PCB设计。
叠层工艺优势
顺络自主研发的叠层电感工艺:
品牌与工艺可靠性
顺络电子是国内电感行业龙头,其叠层电感通过ISO9001、IATF16949等认证,产品一致性与可靠性经市场验证(如应用于华为、小米等品牌终端)。
环境适应性
工作温度范围通常为-40℃+85℃(部分版本支持+125℃),符合无铅焊接要求(回流焊温度曲线适配0201封装),抗振动(10G2000Hz)、抗冲击性能满足消费电子与工业级需求。
环保合规
符合RoHS 2.0、REACH等环保标准,无铅、无镉、无汞,满足全球市场准入要求。
频率匹配
建议工作频率≤1.5GHz(远低于SRF 2GHz),若需更高频率应用,需选择SRF更高的电感型号。
电流设计
实际电路电流需低于额定电流的80%(常温下),高温环境下需进一步降额,避免电感饱和导致电感值下降。
焊接工艺
0201封装尺寸小,需采用高精度贴片机(如富士NXT、西门子 SIPLACE),回流焊温度需控制在220℃~250℃(峰值),避免虚焊、桥连。
电路匹配
24nH电感适合LC滤波、阻抗匹配网络(如50Ω系统匹配),设计时需结合PCB寄生电容、电阻进行仿真优化。
该电感凭借高频性能稳定、小型化、低功耗的特点,成为中高频低功耗电路的优选无源器件,可满足消费电子、物联网等领域的多样化需求。

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.
