FNR252012S8R2MT是长江微电(cjiang) 推出的一款磁胶屏蔽功率电感,专为中低功率电路的储能、滤波需求设计。产品采用表面贴装(SMD)封装,尺寸规格对应公制252012(2.5mm×2.0mm×1.2mm)或英制1008,适配高密度PCB布局,兼具小型化与低EMI优势,是便携式设备、IoT终端等场景的理想选择。
标称电感值为8.2μH,精度±20%,满足大部分中低功率DC-DC变换、电源滤波电路的储能要求。±20%的精度覆盖了批量生产的一致性,无需额外高精度校准,可降低电路设计调试成本。
反映电感线圈的直流损耗,低DCR可减少功率损耗、降低发热,提升电路效率(尤其适合电池供电的便携式设备,延长续航时间)。
磁胶屏蔽结构有效抑制电感工作时的电磁辐射,减少对周边敏感电路(如射频模块、模拟传感器)的干扰,符合EMC电磁兼容要求,无需额外增加屏蔽件。
252012紧凑封装适配轻薄化设备(如智能手表、IoT传感器节点),节省PCB空间,支持电路高密度集成。
工作温度范围为**-40℃至125℃**(长江微电常规规格),适应工业、车载等宽温环境;焊接温度支持260℃/10s(回流焊),兼容标准SMT工艺,无热应力损坏风险。
批量生产参数波动小(电感值、DCR等指标一致性达95%以上),可降低电路批量生产的一致性风险。
FNR252012S8R2MT凭借低EMI、小型化、高可靠性等优势,成为中低功率电路的高性价比选择,可满足多数消费电子与IoT设备的电感需求。

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.
