YNR2510-4R7M是益嘉源(YJYCOIN)推出的一款微型SMD磁胶屏蔽功率电感,针对小型化电子设备的电源系统设计,兼具小体积、低EMI、高效能等特点,适用于便携终端、IoT设备等高密度贴装场景。
作为益嘉源功率电感系列的经典型号,YNR2510-4R7M聚焦小尺寸电源电感需求,以2.5×2×1mm的超小封装实现4.7uH的电感值,同时通过磁胶屏蔽结构降低电磁干扰,解决了便携设备中“空间紧凑”与“EMI兼容”的双重矛盾,是消费电子、IoT终端等领域的高性价比选型。
电感值为4.7uH±20%,符合常规DC-DC转换电路的储能电感需求(如5V转3.3V、3.7V转1.8V等常见电源拓扑);±20%的精度满足大多数电源设计的容差要求,无需额外高精度补偿,降低设计复杂度。
DCR为469mΩ,属于同尺寸电感中的低阻水平,可有效降低电源转换过程中的铜损(损耗=I²×R),提升转换效率(尤其在低电流场景下优势明显),同时减少电感自身发热,延长设备使用寿命。
采用磁胶屏蔽结构,对比非屏蔽电感,可将电磁辐射降低60%以上,减少对周边敏感组件(如射频模块、传感器)的干扰,满足EMC认证要求,适合对电磁兼容有严格要求的产品(如医疗监护设备、通信终端)。
封装尺寸为2.5×2×1mm(长×宽×高),属于0805(英制)或2520(公制)级别的微型封装,可通过自动化贴装设备高效生产,且能在高密度PCB上实现多电感密集布局(如智能手机主板上的4-6个电源电感)。
磁胶不仅提升电感的电磁屏蔽效果,还能增强电感的机械稳定性(减少振动导致的电感值漂移),同时耐温性能优异(常规工作温度-40℃~+85℃),适应不同环境的温度变化。
益嘉源(YJYCOIN)作为国内电感领域的专业厂商,YNR2510-4R7M符合RoHS、REACH等环保标准,批量供货一致性好(电感值偏差≤±20%),可靠性测试通过振动、温度循环等严苛验证,适合消费级、工业级产品的长期稳定使用。

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.
