YNR2512-100M 磁胶屏蔽功率电感产品概述

一、产品定位与核心特性

YNR2512-100M是益嘉源(YJYCOIN)针对小功率便携电子、物联网设备推出的磁胶屏蔽功率电感,核心聚焦“小封装、低EMI、稳定储能”三大需求,适配高密度PCB布局与自动化生产,是中低端便携设备电源管理的高性价比选择。

二、关键参数详解

该电感的参数设计围绕“储能能力、电流承载、损耗控制”平衡,具体如下:

  1. 电感值与精度:标称10uH,精度±20%(实际范围8uH~12uH),满足常规DC-DC转换器的储能需求,批量生产一致性可控;
  2. 额定电流:620mA(定义为温升电流,即电感表面温度升高40℃时的最大连续工作电流),是判断电路电流承载能力的核心指标;
  3. 直流电阻(DCR):531mΩ,直接影响自身功耗(功耗=I²×DCR),额定电流下功耗约0.2W,温升可控,适合连续工作;
  4. 屏蔽特性:采用磁胶屏蔽结构,相比非屏蔽电感可降低辐射EMI(电磁干扰)30%以上,减少对周边敏感电路的干扰。

三、封装与物理特性

YNR2512-100M采用SMD贴片封装,公制尺寸为2.5mm(长)×2.0mm(宽)×1.2mm(高),对应英制标识“2512”(注:为益嘉源定制化小体积封装,实际尺寸更接近常规0805的升级版本),特点如下:

  • 无引脚设计,兼容回流焊/波峰焊工艺,适配自动化贴装线;
  • 体积紧凑,可节省30%以上PCB空间,适合智能手环、蓝牙耳机等便携设备的高密度布局;
  • 磁芯采用高磁导率材料,保证电感值稳定性的同时,降低漏磁。

四、典型应用场景

基于小体积、低EMI、中等电流承载能力,该电感主要应用于:

  1. 小功率DC-DC转换器:手机/平板辅助电源(5V转3.3V/1.8V)、物联网传感器节点电源;
  2. LED驱动电路:智能穿戴状态指示灯、小功率LED串的限流储能;
  3. 便携式电子:蓝牙耳机、智能手表的电源滤波与储能;
  4. 低EMI场景:医疗电子(便携式血糖仪)、工业辅助电路(满足电磁兼容标准)。

五、性能优势分析

相比同体积同类产品,YNR2512-100M具有以下优势:

  1. EMI控制:磁胶屏蔽从根源减少漏磁,无需额外加屏蔽罩,简化PCB设计与成本;
  2. 体积-性能平衡:2.5×2×1.2mm体积下,实现620mA额定电流与531mΩ低DCR,兼顾便携性与效率;
  3. 温度稳定性:磁胶材料温度系数约±10%/℃,在-40℃~+85℃范围内电感值变化可控,适合宽温场景;
  4. 成本可控:益嘉源规模化生产降低成本,适合中低端设备批量采购。

六、选型与使用注意事项

为确保电路稳定,需注意:

  1. 电流匹配:电路最大工作电流需低于620mA(脉冲电流按有效值计算),避免电感饱和导致电感值骤降;
  2. 精度需求:±20%精度满足常规应用,若需高精度滤波(射频电路),需选±10%/±5%精度电感;
  3. 焊接温度:回流焊峰值温度需≤260℃,避免高温损坏磁芯;
  4. 存储环境:存于干燥、无腐蚀性气体环境,防止磁芯受潮影响性能。

该产品通过了常规可靠性测试(如温度循环、振动测试),可满足大部分便携电子的量产需求。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

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
