顺络SDFL1005QR39KTF是顺络电子(Sunlord)推出的0402封装高频小功率贴片电感,属于公司叠层电感系列的核心产品。顺络电子作为国内被动元件龙头企业,专注于片式电感、压敏电阻等产品的研发生产,产品覆盖消费电子、通信、汽车电子等领域,以高一致性、可靠性著称。该型号针对小型化、低功耗高频电路设计,适配便携式设备的紧凑空间需求。
标称电感量390nH,精度±10%(实际范围351nH~429nH),满足多数高频电路的谐振、滤波、阻抗匹配需求,尤其适配蓝牙(2.4GHz)、WiFi(2.4/5GHz)等ISM频段的信号调理。
额定电流15mA(环境25℃下温升≤40℃的最大连续电流),直流电阻600mΩ。两者结合计算,额定电流下功耗仅13.5μW(P=I²R),低功耗特性适配可穿戴、物联网等低功耗场景。
10MHz下Q值为20,Q值反映电感储能与损耗的比值(Q=2πfL/R),Q值越高损耗越小。20的Q值在同封装同电感量产品中处于上游,可有效降低射频电路信号衰减。
自谐振频率85MHz,电感寄生电容与自身电感形成谐振:85MHz以下呈感性,以上呈容性。设计时需避开该频率附近,防止电感性能突变(如阻抗急剧变化)。
采用0402英制封装(公制1005,尺寸1.0mm×0.5mm),是小型化设备的常用封装。贴片结构适配SMT自动化生产,焊盘符合IPC标准,焊接可靠性高;小尺寸可缩小PCB面积,提升设备集成度,适合智能手环、蓝牙耳机等紧凑空间应用。
结合参数与封装特性,该电感主要适用于:
产品符合RoHS 2.0、REACH环保法规,无铅无卤。经过严格可靠性测试:
该产品凭借高频性能、小尺寸与可靠性,成为小型化电子设备射频电路的优选电感之一。

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.
