FNR5040S8R2MT 是长江微电(cjiang)推出的一款表面贴装(SMD)磁胶屏蔽功率电感,外形尺寸约为5×5mm,额定用于中小功率开关电源滤波与储能。该器件以高电流承载和较低直流电阻为特点,适合在空间受限的电源模块中替代传统钳位和绕线电感。
该电感采用磁胶材料与屏蔽结构,降低了磁通外泄与电磁干扰(EMI)。较低的 DCR 有利于降低功耗与温升,提高转换效率。Isat 值表明在接近 3 A 的瞬态或脉冲条件下仍能维持一定的电感量,适合脉冲电流较大的开关节点。
适用于降压(buck)、升压(boost)等开关稳压器的输出或能量存储环节;移动设备、工控电源、车载电子(非关键安全回路)、LED 驱动与通信设备的电源模块等场景。
器件为 SMD 封装,推荐采用无铅回流焊工艺,回流曲线应参考厂商温度资料以避免过热导致磁性材料退磁或塑封件变形。PCB 焊盘布局应保证良好焊点和散热路径,焊盘尺寸与过孔设计按厂商封装图进行。
标称型号 FNR5040S8R2MT,品牌 cjiang(长江微电)。批量采购前建议索取样品并在目标电路中做功耗、温升及电磁兼容测试,确认满足系统需求后再进行量产订购。若需详细封装图、回流曲线或电感频率特性,请联系供应商或查阅产品数据手册。
Request for quote
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.
