YNR6028-680M 产品概述

一、产品简介

YNR6028-680M 是 YJYCOIN(益嘉源)推出的一款表贴功率电感,型号命名对应 6×6×2.8mm 封装与 68µH 标称电感。器件为磁性屏蔽结构的 SMD 功率电感,专为中低功率 DC-DC 转换、电源滤波与电流隔离场合设计,兼顾体积、温升与抗磁干扰性能。

二、主要参数与含义

  • 电感值:68µH(标称) ±20%(公差)
  • 额定电流(Irated):800mA —— 在该电流下长期工作且温升可控
  • 饱和电流(Isat):800mA —— 电感在该直流偏置下开始显著降感
  • 直流电阻(DCR):360mΩ —— DCR 较高,影响损耗与效率
  • 类型:磁胶/磁屏蔽电感(屏蔽结构,减小外泄磁场)
  • 封装:SMD,尺寸 6.0×6.0×2.8mm

以上参数为选型和热设计的基础,应结合实际电路的直流偏置、纹波电流与工作温度来评估。

三、器件特性与优劣势

  • 优点:体积小、屏蔽性能好,可并联或单独用于滤波与能量储存;适合占板面积受限的中低功率模块。
  • 局限:DCR 较高(360mΩ),在接近额定电流时功耗显著,应关注温升与效率;Isat 与 Irated 相同,意味着在略高电流下电感量会迅速降低,不适合需要大电流余量的电源设计。

四、典型应用

  • 同步/非同步降压(buck)转换器的滤波与储能(中低电流)
  • 开关电源的输出滤波、输入去耦
  • LED 驱动、便携电源模块、工业仪表的局部电源滤波
  • 对 EMI 有一定抑制需求的电路中作为屏蔽型电感使用

五、选型与使用建议

  • 电流裕量:建议实际工作电流 ≤ Irated 的 60%–80%,以避免接近饱和和过高温升;若纹波电流较大,应按峰值评估饱和影响。
  • 效率考量:DCR 360mΩ 在功率计算中不可忽略,P = I²·R,按最大工作电流估算功耗并验证温升。
  • 布局建议:靠近开关管或整流二极管放置以缩短高 di/dt 回路;采用宽铜箔和过孔加强电流承载与散热;输入/输出电容尽量靠近电感两端。
  • 并联使用:若单只电感无法满足电流需求,可考虑多只并联,但需注意绕组不完全均流与占板空间。
  • 温度与环境:留足散热空间,遵守焊接工艺规范,避免在高温潮湿环境长期靠近满载工作。

六、封装、采购与质量保证

YNR6028-680M 提供标准 SMD 卷带/盘式包装(常见),便于自动贴装。采购时建议索取样品进行温升与电感随直流偏置的测量报告,确认是否满足目标应用的可靠性与寿命要求。作为设计工程师,应在样品验证阶段完成电性、热性与电磁兼容性测试,确保最终产品稳定运行。

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
