FNR3012S470MT是长江微电(cjiang)推出的一款小型化贴片式(SMD)磁胶屏蔽功率电感,专为低功耗、高密度布局的电子设备设计,凭借紧凑尺寸、稳定电气性能及低EMI特性,成为消费电子、物联网终端等领域的实用选型。
该电感属于磁胶屏蔽型功率电感,通过特殊树脂材料包裹磁芯实现双重优势:既减少电磁干扰(EMI)对外辐射,又避免金属屏蔽带来的额外体积与成本;同时磁胶的柔性结构可缓解振动对性能的影响。
封装上采用3×3mm SMD(对应3012封装规格,长3.0mm、宽3.0mm、高约1.2mm),适配小型化设备的高密度布局需求,贴片式设计支持自动化贴装,提升生产效率。
标称电感值为47μH,精度±20%,属于工业级常规精度范围,可满足大部分电源滤波、储能场景(无需极高精度的普通DC-DC转换、输出滤波等)。实际应用中,±20%的偏差可通过设计裕量解决,不影响基本功能。
标称1.885Ω,反映绕组铜损,数值越低损耗越小。该值在3×3mm封装的47μH电感中属中等水平,兼顾了电感值与损耗的平衡(若追求更低损耗需选择更大封装或更高成本材料)。
磁胶屏蔽的核心价值体现在电磁兼容性(EMC):
此外,磁胶电感成本低于金属屏蔽电感,重量更轻,适合对成本敏感、体积紧凑的消费电子(如TWS耳机、智能手环)。
FNR3012S470MT的参数适配以下场景:
长江微电(cjiang)专注功率电感研发生产,产品符合RoHS、REACH环保标准;FNR3012S470MT经高低温循环、振动测试,满足工业级与消费级设备长期稳定运行需求,适合中小批量至大规模生产选型。

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.
