FNR6045S330MT 是长江微电(cjiang)推出的一款面向电源应用的磁胶屏蔽功率电感,封装为 SMD,外形紧凑(6×6mm)。该器件以 33µH 的感值、较高的额定电流和屏蔽结构为特点,适用于多种开关电源和电源滤波场合,在尺寸、散热与抗干扰之间做了平衡,便于在中小功率点式负载与模块电源中集成使用。
电感的直流损耗主要来自 DCR,对于连续额定电流 1.6 A,直流损耗可按 P = I^2 × DCR 估算:
该损耗在小尺寸器件上会带来较显著的温升,实际温升受 PCB 散热、铜箔面积和环境温度影响。建议在设计时:
总结:FNR6045S330MT 是一款面向中小功率点载荷与开关电源滤波的磁胶屏蔽功率电感,兼顾了体积、抗干扰与电流承载能力。在设计时需关注直流损耗与散热,合理进行电流降额与 PCB 布局,即可在多种电源应用中稳定工作并发挥良好性能。若需更高电流能力、更低 DCR 或更严格感值公差,可咨询供应商以获得替代型号建议。

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.
