SDCL0603Q6N2BT02B03是顺络电子(Sunlord)推出的0201封装叠层贴片电感,针对低功耗、高频段应用场景设计,兼顾电气性能与空间效率,属于小型化射频/数字电路的专用核心器件,适用于消费电子、物联网终端等对尺寸敏感的产品。
该电感的关键参数直接决定应用范围,具体解析如下:
电感值:6.2nH
标称电感值为6.2纳亨,属于小电感范畴,主要用于射频电路的阻抗匹配、滤波网络(如低通/带通滤波),或数字电路的去耦、EMI抑制(配合电容形成LC回路)。电感值精度满足常规射频设计需求,叠层工艺保证参数一致性。
额定电流:300mA
额定电流(Isat)定义为电感值变化≤±10%时的最大直流电流,300mA的指标适用于低功耗设备(如可穿戴设备、蓝牙模块)的供电/信号支路,避免电流过大导致电感饱和,影响电路性能。
直流电阻(DCR):480mΩ
480毫欧的DCR在0201封装叠层电感中处于较低水平,可减少电流损耗(P=I²R),降低设备发热,提升电路效率,尤其适合对功耗敏感的移动终端。
品质因数(Q值):[email protected]
Q值反映电感损耗特性(Q=2πfL/Rs,Rs为串联电阻),[email protected]的Q值表明在500MHz射频频段内损耗小,适合蓝牙(2.4GHz)、WiFi(2.4G/5G)等主流无线频段的信号处理,减少信号衰减。
自谐振频率(SRF):5.1GHz
SRF是电感与寄生电容谐振的频率,超过该频率后电感呈电容特性。5.1GHz的SRF意味着产品可在DC~5GHz频段稳定工作,覆盖WiFi 5G、蓝牙5.0等高频应用,满足无线通信需求。
封装尺寸:0201(英制)
封装尺寸为0.6mm×0.3mm(公制),是超小封装之一,可显著节省PCB空间,适合高密度集成的终端产品(如智能手表、TWS耳机)。
叠层结构优势
采用多层陶瓷叠层工艺,相比绕线电感具有:
该电感的参数与封装特性决定其主要应用于:
顺络作为国内电感龙头,该产品可靠性体现在:
综上,SDCL0603Q6N2BT02B03是小型化高频应用的高性价比选择,兼顾性能与尺寸,可满足多种消费电子与物联网场景的核心需求。
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.
