FNR4030S270MT是长江微电(cjiang)推出的一款小型化磁胶屏蔽功率电感,专为低EMI(电磁干扰)、高可靠性的电子电路设计,适用于消费电子、车载电子、LED驱动等多领域的电源管理场景。该产品采用SMD贴片封装,体积紧凑(4×4mm),兼具高电感值与高电流承载能力,是中小功率电路中电感选型的高性价比方案。
FNR4030S270MT属于磁胶屏蔽型功率电感,相比普通非屏蔽电感,磁胶结构能有效抑制电磁辐射,降低对周边电路的干扰;同时,其紧凑的4×4mm封装适配主流贴片生产工艺,可直接集成于高密度PCB板,满足小型化电子设备的设计需求。核心优势包括:
该产品的关键参数直接决定了其应用范围,具体解析如下:
电感值为27μH±20%,属于中小功率电感的典型值,满足DC-DC转换器、LED驱动等电路对电感储能的需求。±20%的精度符合工业级电感的通用标准,可覆盖大多数非超高精度的电源设计场景,无需额外的电感匹配调试。
DCR为338mΩ,反映了电感绕组的电阻损耗。低DCR意味着在相同电流下,电感自身的功耗(I²R)更低,例如当工作电流为1A时,功耗仅0.338W,可提升DC-DC转换器的转换效率(通常提升1%-2%),适配电池供电的低功耗设备。
采用SMD贴片封装,尺寸为4×4mm(长×宽),高度符合行业通用标准(通常≤2mm),适配0402、0603等周边贴片元件,支持自动贴装(SMT),生产效率高,适合批量生产的高密度PCB设计。
FNR4030S270MT的参数特性使其适用于以下场景:
FNR4030S270MT由长江微电(cjiang) 生产,该品牌是国内专注于功率电感研发与制造的企业,拥有10余年电感设计经验,产品覆盖消费电子、车载、工业等领域。该电感符合RoHS、REACH等环保标准,且通过UL、CE等安全认证,可靠性得到市场验证。
此外,产品采用高品质铁硅铝磁芯与漆包铜线绕组,在-40℃至+85℃的宽温度范围内性能稳定,可满足不同环境下的工作需求,例如车载环境的高低温变化、工业现场的温度波动。
在使用FNR4030S270MT时,需注意以下几点:
综上,FNR4030S270MT是一款性能均衡、性价比高的磁胶屏蔽功率电感,可满足多领域中小功率电路的电感需求,是电子设计中电感选型的可靠选择。
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.
