SDCL0603Q27NHT02B03是顺络电子(Sunlord)推出的一款高性能贴片电感,专为高密度、低功耗的射频及便携式电子设备设计,凭借紧凑的0201封装、精准的电气参数及优异的射频特性,成为小型化电路设计的优选组件。
该型号属于顺络常规贴片电感系列,0201封装(对应公制尺寸0.6mm×0.3mm)是目前贴片电感中体积最小的规格之一,适配SMT自动化生产,可显著提升PCB布局密度,满足智能手机、智能穿戴等设备的“轻、薄、小”设计需求。其贴片式结构无引线设计,能有效降低寄生电容与电感,减少信号传输损耗,适合高频电路的信号完整性要求。
电感标称值为27nH,精度达**±3%**——高于行业常规±5%的精度标准,可精准匹配射频匹配网络、振荡电路等对电感值偏差敏感的场景,避免因参数偏移导致的信号失真或性能下降。
额定直流电流为140mA,指电感在直流电流下能长期稳定工作而不出现性能劣化(电感值偏移≤10%)的最大电流。实际应用中建议预留20%以上余量(即工作电流≤112mA),避免过载导致的发热加剧或元件损坏。
DCR为1.6Ω,属于同封装同电感值产品中的低阻水平。低DCR可减少电流通过时的功率损耗(P=I²R),降低元件发热,尤其适合低功耗物联网设备、便携式电子的电池供电场景,延长设备续航时间。
在500MHz频率下Q值为13,Q值反映电感储能与能量损耗的比值(Q=2πfL/R),直接影响射频电路的效率。13的Q值在中高频段表现优异,可有效提升射频前端的信号增益,减少滤波电路的插入损耗。
自谐振频率为2GHz,即电感与自身寄生电容谐振的频率。当工作频率接近或超过SRF时,电感会呈现电容特性,失去电感功能。因此该型号适合工作在1GHz以下的射频场景(如蓝牙4.2/5.0的1GHz子频段、WiFi 2.4GHz的低频段匹配),若需在2GHz以上应用需结合电路重新设计匹配网络。
综上,SDCL0603Q27NHT02B03以“小体积、高精度、低损耗、优射频特性”为核心优势,精准覆盖便携式与射频电路的设计需求,是顺络在小型化电感领域的代表性产品之一。

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.
