YNR6028-4R7N 产品概述
一、产品简介
YNR6028-4R7N 是益嘉源（YJYCOIN）推出的一款表面贴装功率电感，尺寸 6.0×6.0×2.8 mm，采用磁胶屏蔽结构，适用于各类开关电源与电源滤波场合。器件体积小、载流能力强，便于自动贴装与高密度电路设计。
二、主要参数
- 感值：4.7 μH
- 公差：±30%
- 额定电流：3 A
- 饱和电流(Isat)：3 A（磁性材料在该电流下开始明显饱和）
- 直流电阻(DCR)：约 30 mΩ
- 类型：磁胶屏蔽电感（shielded）
- 封装/尺寸：SMD，6×6×2.8 mm
- 品牌/型号：YJYCOIN YNR6028-4R7N
三、产品特性与优势
- 低 DCR：约 30 mΩ 有利于降低铜耗与热量，提升转换效率。
- 较高电流能力：3 A 的额定与饱和电流适合小功率或中功率降压转换器。
- 屏蔽结构：磁胶屏蔽设计减小磁泄露，降低对周围敏感元件的干扰，利于高密度布板。
- SMD 小封装：适配自动贴装及回流焊工艺，便于批量生产。
四、典型应用场景
- DC-DC 降压（Buck）转换器输出滤波与储能元件
- 电源管理模块、便携设备电源、通信设备供电
- LED 驱动、车载电子低功耗电源（需按温升与可靠性评估）
五、选型与使用建议
- 电流裕量：在选择时建议对峰值电流和脉冲电流进行裕量考虑，避免长期在额定电流附近工作导致温升或退磁。
- 布局：将电感靠近开关管与整流二极管或同步管放置，输入/输出走短、粗的铜箔，增加过孔以利散热。
- 热管理：留意器件温升，必要时评估环境温度与散热条件，确保长期可靠。
- 焊接工艺：支持常规 SMT 回流焊，建议遵循器件供应商回流曲线并避免多次超温回流。
六、可靠性与检验建议
- 进货检验包含外观、DCR、感值及耐温循环测试；关键应用建议进行电流寿命与温度漂移评估。
- 在高振动或冲击环境应验证机械牢固性与焊点可靠性。
YNR6028-4R7N 以其紧凑封装、屏蔽结构与良好的载流能力，适合要求空间与电性能兼顾的电源设计场合。选型时请参考完整数据手册并结合实际工作条件进行验证。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
