VHF100505HQ27NJT 为风华(FH)系列高频叠层贴片电感,标称感值 27 nH,公差 ±5%。典型电气参数(需以厂方规格书为准)包括:额定电流约 900 mA,直流电阻(DCR)约 90 mΩ,品质因数 Q ≈ 8(@100 MHz),自谐振频率(SRF)约 1.6 GHz。封装形式为 0402(约 1.0 mm × 0.5 mm),属于小型化高频电感元件,适用于 VHF 及更高频段电路中的阻抗匹配、谐振与滤波应用。
注:用户提供信息中存在参数矛盾(例如一处记录为 DCR 700 mΩ、额定电流 300 mA)。在设计前请以厂家最终数据表为准,或明确采购型号与规格一致性。
以 DCR = 90 mΩ、额定电流 900 mA 为例,电阻发热功耗 P = I^2·R ≈ 0.9^2 × 0.09 ≈ 73 mW。若实际信息为 DCR = 700 mΩ、额定电流 300 mA,则 P ≈ 0.3^2 × 0.7 ≈ 63 mW。两种情形功耗数量级相近,但允许电流和温升限制会不同,务必基于确切规格确定最大通流能力与温升预算,避免超过磁芯饱和或引起过热失效。
VHF100505HQ27NJT 是一款面向 VHF 高频应用的小型叠层贴片电感,适合空间受限且需在 100 MHz 附近提供若干欧姆感抗的场合。由于资料中出现 DCR 与额定电流的两套不同数据(90 mΩ/900 mA 与 700 mΩ/300 mA),建议在设计与采购前向供应商索取最新数据手册并确认样片测试结果,确保电流、温升与频率特性满足系统可靠性与性能要求。若需,我可以根据您给出的确切数据表进一步给出 PCB 封装图、等效电路模型及仿真参数建议。

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.
