YSMC0420V-3R3M是益嘉源(YJYCOIN)推出的小体积高密度一体成型功率电感,专为中低功率电子设备的电源管理、滤波及储能场景设计。其4×4mm的紧凑SMD封装适配自动化生产,同时兼顾电流承载能力与电磁兼容性,广泛应用于消费电子、车载电子、工业控制等领域的关键电路中。
典型应用场景包括:
该电感的核心参数针对功率电路需求优化,关键指标如下:
电感标称值为3.3μH,精度±20%,满足中频段(100kHz~1MHz)DC-DC转换器的储能与滤波需求,无需额外复杂的匹配电路即可实现稳定的电压输出。
直流电阻为43mΩ,属于同类4×4mm封装电感中的低损耗水平,显著降低铜损,提升电源转换效率(可使DC-DC效率提升约1%~2%,对于高功率密度设计尤为关键)。
采用4×4mm SMD表面贴装封装,厚度符合工业标准(典型2mm),兼容回流焊工艺,适配高密度PCB布局,有效节省设备内部空间。
YSMC0420V-3R3M采用一体成型磁屏蔽结构,相比传统开放式电感具有明显优势:
磁芯完全包裹线圈,有效抑制电磁辐射与传导干扰,降低对周边敏感电路的影响,减少EMC测试整改成本。
一体成型结构抗振动、抗冲击性能优异(可通过10g/50~2000Hz振动测试),适合车载、工业等 harsh 环境;同时磁芯与线圈结合紧密,无松动风险,提升长期可靠性。
低DCR减少自身发热,配合磁芯的低热阻特性,可在-40℃~125℃的宽温度范围内稳定工作,满足极端环境下的应用需求。
建议工作频率范围为100kHz~1MHz,此范围内电感值稳定,转换效率最高;若频率过低,电感体积需增大,本款不适用;频率过高则磁芯损耗增加,需结合实际需求评估。
YSMC0420V-3R3M作为一款小体积、高电流、低损耗的一体成型功率电感,兼顾了性能与成本优势,适合中低功率电子设备的电源管理场景。其紧凑封装、优异的EMC性能及宽温度范围工作能力,使其成为消费电子、车载、工业控制等领域的高性价比选型。

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.
