LQG15HS1N8B02D 为 muRata(村田)推出的一款贴片高频电感,主要参数如下:标称电感值 1.8 nH,直流电阻(DCR)约 80 mΩ,品质因数 Q = 8(@100 MHz),自谐振频率(SRF)约 6 GHz,额定电流 950 mA,封装尺寸为 0402(公制约 1.0 × 0.5 mm)。这些参数决定了该器件在 MHz 至 GHz 级别射频电路中的性能与应用场景。
(补充计算示例:在 100 MHz 时电感的感抗 XL = 2πfL ≈ 1.13 Ω,按 Q = XL/ESR,可估算交流等效串联电阻约 0.14 Ω,和 DCR 一致量级,表明高频损耗主要由器件固有寄生与材料损耗决定。)
选择时除参考上述主要参数外,还应查看完整频率响应、温度特性与封装机械尺寸图。若需更高电流或更低 DCR,可考虑更大封装(如 0603/0805)的同系产品;若需更高 Q 或更高 SRF,可选择专用射频电感或线圈。最终选型应结合目标频段、插入损耗、空间与可靠性要求进行权衡。
总结:LQG15HS1N8B02D 以其小体积、适中电感值与 GHz 级 SRF,适合用于移动通信与各类射频前端电路,在 PCB 设计中通过合理布局和热/电流裕量可以发挥出良好的高频性能。若用于关键应用,建议参考 muRata 官方数据手册并进行实际板级验证。

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.
