YNR5040-3R3M是益嘉源(YJYCOIN)针对中功率密度电源系统推出的小型化磁胶屏蔽功率电感,核心定位是平衡“小体积、低损耗、低EMI”三大需求,适配消费电子、工业控制、汽车电子等领域的紧凑式电路设计。
具体应用场景包括:
该电感的参数设计围绕“功率适配性”与“效率优化”展开,核心参数及价值如下:
电感值与精度:3.3uH ±20%
3.3uH是中功率DC-DC(如BUCK拓扑)的常用规格,适配3.3V-12V输出电压、100kHz-500kHz开关频率;±20%精度满足多数功率应用的误差要求,无需额外校准。
额定电流:3.4A
此为温升电流(电感表面升温40℃时的最大持续电流),可支撑多数中功率负载稳定运行;短期过载可耐受1.2-1.5倍峰值电流(需散热设计)。
直流电阻(DCR):24mΩ
低DCR是降低铜损的核心——3.4A持续电流下,铜损仅约0.27W,比同类非屏蔽电感低15%以上,可提升电源转换效率1-2%(依电路设计调整)。
磁胶屏蔽特性
磁胶封装相比非屏蔽电感,电磁辐射(EMI)降低10-15dB,无需额外屏蔽罩,节省电路空间,适配对EMI敏感的射频/传感器电路。
YNR5040-3R3M采用SMD 5040封装(5.0mm×5.0mm×4.0mm),结构兼顾小型化与可靠性:
该电感满足工业级与汽车级基础可靠性要求:
YNR5040-3R3M是一款性价比突出的小型化磁胶屏蔽电感,通过低DCR、低EMI与紧凑封装的组合,可有效提升中功率电源系统的效率与可靠性,适配多领域紧凑式电路设计需求。

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.
