FNR5040S332MT是长江微电(cjiang)推出的磁胶屏蔽贴片功率电感,型号命名逻辑清晰:
该产品定位为小功率低EMI电感,核心服务于对体积、电磁干扰敏感的小型电子设备,兼顾可靠性与成本优势。
标称电感值为3.3mH,精度±20%,属于功率电感常规精度范围,可满足多数民用级、工业级低精度电路需求(如电源滤波、低功耗DC-DC),无需额外高精度匹配元件。
该参数反映绕组铜损,120mA额定电流下的功率损耗约为0.36W(P=I²R=0.12²×25.2),符合小功率电感的损耗控制要求,可有效降低电路发热。
采用5.0×5.0×4.0mm SMD封装,适配自动化贴装生产线,生产效率高;同时便于集成到紧凑PCB布局中,满足电子设备轻薄化趋势。
相比传统开放式电感,磁胶屏蔽可显著降低电磁辐射(EMI),减少对周边敏感电路(如射频模块、传感器)的干扰;同时提升电感自身抗干扰能力,适配EMC要求严格的场景。
工作温度范围为**-40℃105℃**,可适应宽温环境(如户外物联网终端、车载辅助设备),存储温度需控制在-40℃85℃、湿度≤60%,避免磁胶性能劣化。
FNR5040S332MT因体积小、低EMI、小电流特性,广泛应用于:
FNR5040S332MT是一款专为小功率、低EMI场景设计的磁胶屏蔽贴片电感,凭借小体积、稳定性能和长江微电的品质保障,成为智能穿戴、物联网等领域的优选元件,可有效满足紧凑电路设计的性能与可靠性需求。

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.
