YNR3015-470M是益嘉源(YJYCOIN)推出的一款小型化贴片功率电感,专为空间紧凑、电磁干扰(EMI)要求较高的电子设备设计。其核心参数覆盖47uH电感值、350mA额定电流等,兼具低功耗、屏蔽性与高可靠性,适配多种低功耗电源与滤波场景。
该产品属于磁胶屏蔽型功率电感,区别于信号电感(侧重信号传输),其核心作用是实现电路中的储能、滤波与电压转换。磁胶屏蔽设计通过磁胶材料包裹磁芯,有效抑制电感工作时的电磁辐射,降低对周边敏感电路的干扰,是中低功率、EMI规范严格场景的优选方案。
标称电感值为47uH(微亨),精度±20%,实际电感范围为37.6uH~56.4uH。该精度等级满足大部分中低功率DC-DC转换器、滤波电路的设计需求,无需额外高精度筛选,可降低电路成本。
额定电流为350mA(直流),指电感持续工作时,线圈温升不超过行业标准(30℃~40℃)的最大电流。需注意:若电路峰值电流超过350mA,可能导致磁芯饱和,电感值急剧下降,影响电路稳定性。
DCR为1.25Ω(欧姆),是电感线圈导线的直流电阻,直接影响功耗——当电流为350mA时,功耗约为(I^2 \times R = 0.35A^2 \times 1.25Ω ≈ 0.153W),属于低功耗水平,可有效减少电路发热。
采用磁胶屏蔽工艺,对比非屏蔽电感,其辐射干扰强度可降低10dB以上(典型值),符合欧盟CE、中国CCC等EMI认证要求,适合敏感电路(如传感器、蓝牙模块)周边应用。
封装规格为SMD(表面贴装),物理尺寸为(3.0mm \times 3.0mm \times 1.5mm)(长×宽×高),属于紧凑型贴片封装。该尺寸适配高密度PCB布局,支持自动化贴装(SMT),焊接可靠性符合IPC标准,适合批量生产。
智能手机、平板的DC-DC降压模块(如CPU、内存供电的辅助滤波),利用小型化封装节省主板空间,同时磁胶屏蔽减少对射频电路的干扰。
智能手环、手表的低功耗升压电路(如电池到屏幕的供电转换),磁胶屏蔽可避免对心率传感器等敏感元件的干扰,提升设备稳定性。
低功耗蓝牙模块、温湿度传感器节点的滤波电路,抑制电源纹波,保障信号传输的准确性。
5V/1A充电器的EMI滤波电感,满足电磁兼容要求,避免干扰周边电子设备(如WiFi、蓝牙设备)。
益嘉源(YJYCOIN)作为国内电感专业制造商,其磁胶电感采用自主研发的磁胶配方,磁芯稳定性好、温度系数低(-20℃~85℃范围内电感值变化≤10%);产品符合RoHS 2.0环保标准,无铅焊接兼容,适合出口与国内市场需求;批量供货时可提供一致性检测报告,保障电路设计的可靠性。
YNR3015-470M凭借小型化封装、磁胶屏蔽、低功耗等优势,成为中低功率、空间紧凑电子设备的优选电感,适配多场景应用,兼顾性能与成本,是消费电子、IoT终端等领域的可靠选择。
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.
