YNR2510-4R7M 磁胶屏蔽功率电感产品概述

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。

一、产品核心定位与身份

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。

二、关键性能参数解析

1. 电感特性与精度

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。

2. 电流承载能力

  • 额定电流(Irms):700mA:连续工作时的最大电流阈值,超过此值会导致电感发热加剧、性能衰减;
  • 饱和电流(Isat):950mA:电感值下降30%时的峰值电流,是电源设计中峰值电流的参考上限,可避免电感饱和导致输出电压异常。

3. 直流电阻(DCR)

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。

4. 屏蔽特性

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)。

三、封装与结构优势

1. 超小SMD封装

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)。

2. 磁胶屏蔽结构

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。

四、典型应用场景

1. 便携电子设备

  • 智能手机/智能手表:用于CPU、蓝牙、传感器等模块的DC-DC降压电路,小尺寸节省主板空间,屏蔽型减少对射频信号的干扰;
  • 蓝牙耳机/便携音箱:满足低功耗、小体积需求,469mΩ的DCR降低待机损耗,延长电池续航。

2. IoT终端设备

  • 传感器节点/智能门锁:工作电流通常在100-500mA之间,额定电流700mA完全覆盖,屏蔽型减少节点间的电磁串扰;
  • 智能家居控制器:适配低功耗MCU的供电需求,批量供货稳定,适合量产。

3. 小型电源模块

  • DC-DC降压/升压模块:如5V转3.3V(输出电流500mA)、3.7V转5V(输出电流300mA)等场景,电感储能性能匹配;
  • 移动电源升压电路:满足小体积、高效能的设计要求。

五、选型与使用注意事项

  1. 电流匹配:设计时需确保连续工作电流≤700mA,峰值电流≤950mA,避免电感饱和或过热;
  2. 精度需求:若应用对电感值精度要求高于±20%(如射频电路),需选择更高精度等级的电感;
  3. 贴装工艺:小封装需注意贴装精度(建议贴装偏移量≤0.1mm),避免影响电感性能;
  4. 温度环境:常规工作温度为-40℃~+85℃,若应用于高温场景(如汽车电子),需确认厂商的高温升级型号。

六、品牌与品质保障

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。

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
