YNR4020-2R2N 产品概述

一. 产品简介

YNR4020-2R2N 是益嘉源(YJYCOIN)推出的一款功率型磁胶屏蔽贴片电感,体积为 SMD 4×4×2 mm。该器件以 2.2µH 标称电感值、±30% 容差为主要规格,针对开关电源与电流滤波场景优化,兼顾紧凑尺寸与较高通流能力,适用于空间受限且需一定电流传输的电源过滤与储能环节。

二. 主要参数

  • 电感值:2.2 µH(标称)
  • 精度:±30%
  • 额定电流(Irms):1.85 A
  • 饱和电流(Isat):3.4 A
  • 直流电阻(DCR):约 40 mΩ
  • 类型:磁胶屏蔽电感(磁屏蔽、减少外泄磁场)
  • 封装:SMD,4 × 4 × 2 mm
  • 品牌:YJYCOIN(益嘉源)
  • 型号:YNR4020-2R2N

三. 主要特性

  • 小型化:4×4×2 mm 紧凑封装,便于高密度 PCB 布局。
  • 较高通流能力:额定电流 1.85 A,饱和电流 3.4 A,适合中小功率开关稳压器输入/输出回路。
  • 低 DCR:约 40 mΩ,减小铜损,有利于提高转换效率并降低温升。
  • 磁胶屏蔽结构:有效抑制磁通外泄,减小对周围元件的干扰,利于系统 EMI 优化。
  • SMD 贴片工艺:适配常规回流焊工艺,便于自动化贴装与批量生产。

四. 典型应用

  • DC-DC 降压/升压转换器(输入/输出滤波)
  • 电源管理模块(PMIC)与点对点供电
  • 通信设备与消费电子的电源滤波
  • 工业与汽车电子中对体积与效率有平衡要求的直流电源

五. 推荐使用与注意事项

  • 额定电流说明:额定电流为器件在允许的温升范围内连续工作的推荐值,实际应用时应考虑环境温度、PCB 散热及相邻发热元件影响并适当留有裕量。
  • 饱和电流:当通过器件电流接近或超过 Isat(3.4 A)时,电感值会明显下降,需避免长期运行于饱和区域。
  • 温升与散热:建议在目标工作点进行温升测试,确认 DCR 导致的功耗和温度在可接受范围内。
  • 焊接工艺:采用标准回流焊流程,避免超出推荐温度曲线的长时间高温暴露以防性能退化。
  • PCB 布局:电感附近布线尽量短且宽,输入输出旁的去耦与旁路电容紧邻布置以优化环路性能与减少 EMI。
  • 环境限制:产品为通用磁胶屏蔽电感,若有特殊耐高温、汽车 AEC 级或医疗认证要求,请向供应方确认相应型号与证书。

六. 封装与订购信息

  • 封装形式:SMD 4×4×2 mm,适配自动化贴装。
  • 包装方式:常见为卷带(Tape & Reel),便于 SMT 生产线使用(具体包装请向供应商确认)。

七. 选型建议

  • 若系统电流接近或超过 1.85 A,建议选择额定电流更高或 DCR 更低的器件以降低发热并延长寿命。
  • 对 EMI 有较严要求的设计,可优先选用磁屏蔽结构的电感以减少磁干扰。
  • 在关键电源路径上,建议在样机阶段进行实际电流、温升和电感衰减测试,以验证是否满足系统可靠性要求。

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
