YNR2512-3R3M 磁胶屏蔽功率电感产品概述

一、产品定位与核心优势

YNR2512-3R3M是益嘉源(YJYCOIN)针对小型化、低功耗电子设备优化的磁胶屏蔽功率电感,核心聚焦“高密度布线适配、低损耗发热、抗电磁干扰”三大需求,适配主流贴片自动化生产,是便携电子、物联网节点等场景的电源设计优选。

二、关键参数深度解析

1. 电感值与精度

标称电感值3.3μH,精度±20%,覆盖5V→3.3V、3.7V→1.8V等常见DC-DC降压拓扑的电感量需求。宽精度范围降低了设计对电感一致性的苛刻要求,同时提升供应链选型灵活性(无需过度依赖同批次一致性)。

2. 额定电流特性

额定电流1.04A(环境温度25℃下,电感自身温升≤40℃的最大连续电流),精准匹配小型设备典型负载:

  • 智能手表CPU/蓝牙芯片(工作电流0.5-1A);
  • TWS耳机充电盒(输出电流0.8-1A);
  • 物联网传感器节点(峰值电流≤1A)。
    若需应对短时间峰值电流,建议降额至80%额定电流(≤0.83A),避免磁芯饱和导致电感量骤降。

3. 直流电阻(DCR)

203mΩ的低DCR是核心亮点:铜损与电流平方成正比((P=I^2R)),1A负载下铜损仅约0.2W,比同封装普通电感(DCR≥300mΩ)低30%以上,可直接提升DC-DC转换效率1%-2%,显著降低电源模块发热。

4. 屏蔽特性

采用磁胶屏蔽结构,相比非屏蔽电感,电磁辐射(EMI)降低10-15dB,有效减少对周围射频电路(WiFi、蓝牙)的干扰,符合便携设备对电磁兼容性(EMC)的严格要求(如智能手机射频频段的干扰抑制)。

三、封装与结构设计

1. 封装规格

SMD贴片封装,公制尺寸2.5×2.0×1.2mm,尺寸紧凑(仅相当于指甲盖1/10大小),适配高密度布线的小型设备:

  • 智能手环内部PCB(面积仅3-5cm²);
  • 蓝牙耳机本体(厚度≤10mm)。

2. 结构细节

  • 磁芯材料:高磁导率磁胶,兼具低损耗(高频下磁损小)与抗振动特性(适配手持设备跌落场景);
  • 绕组设计:多股细径漆包线,平衡电感量与DCR(单股线易导致DCR过高);
  • 引脚工艺:镀锡处理,提升焊接可靠性(焊点强度提升20%)与抗氧化能力(存储12个月无明显氧化)。

四、典型应用场景

  1. 便携电子:智能手机PMU(电源管理单元)、智能手表CPU供电电路,低EMI避免干扰射频信号,小封装适配窄边框设计;
  2. 小型消费电子:TWS耳机充电盒、蓝牙音箱的DC-DC降压模块,1.04A电流满足功放与芯片负载;
  3. 物联网节点:智能家居温湿度传感器、可穿戴健康设备(如心率带)的电源模块,低损耗延长电池续航(单节纽扣电池可工作6-12个月);
  4. 车载小功率电路:车载蓝牙模块、QC/PD充电器的辅助电源,磁胶屏蔽减少对CAN总线的干扰,适配-40℃~+85℃车载环境。

五、选型与应用注意事项

  1. 电流匹配:负载电流需≤1.04A(连续),峰值电流≤1.2A(短时间,≤100ms);
  2. EMI优化:若应用EMI要求极高(如医疗设备),可配合0.1μF滤波电容并联在电感两端;
  3. 贴装工艺:回流焊峰值温度≤260℃(时间≤10s),避免磁芯开裂;波峰焊需控制引脚浸锡深度(≤0.5mm);
  4. 存储条件:温度25℃±5℃、湿度≤60%,避免长期暴露在高湿环境(如沿海地区需密封存储)。

YNR2512-3R3M通过“小封装+低损耗+屏蔽”的组合优势,精准命中小型电子设备的电源设计痛点,是替代传统插件电感或非屏蔽电感的高性价比方案。

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
