YNR6028-330M 产品概述
一、产品概述
YNR6028-330M 是益嘉源（YJYCOIN）推出的一款磁胶屏蔽功率电感，封装为 SMD 6×6mm，电感值标称为 33 μH，公差 ±20%。该器件面向开关电源和电源滤波场景设计，具有相对较低的直流电阻（DCR 185 mΩ）和中等额定电流（1.22 A），饱和电流 Isat 为 1.35 A，适用于空间受限且对电流要求不超过其额定值的应用。
二、主要性能特点
- 电感值：33 μH，允许 ±20% 公差。
- 额定电流：1.22 A（持续工作参考值）；饱和电流（Isat）：1.35 A（电感明显下降前的近似上限）。
- 直流电阻：约 185 mΩ，代表器件的铜损及稳态功耗。
- 类型：磁胶屏蔽结构，提高电磁兼容性并减小邻近元件干扰。
- 封装：SMD，6×6 mm 规格，适合自动贴装与回流焊工艺。
三、典型应用
- DC-DC 降压/升压转换器的输出滤波与能量存储。
- 开关电源（SMPS）与电源模块的输入/输出滤波。
- LED 驱动、电机驱动低功耗通道的滤波与去耦。
- 移动设备、物联网节点、便携式设备及工业控制中空间受限的稳压方案。
四、设计与选型建议
- 电流裕量：建议在实际设计中对额定电流做 20% 以上的裕量，以降低温升并避免接近饱和区工作。
- DCR 损耗：185 mΩ 在较高负载下会产生显著功耗与热量，需评估系统热预算与散热条件。
- 饱和考虑：在瞬态大电流冲击或启动时，注意 Isat 限制，避免电感值骤降影响电路稳定。
- PCB 布局：尽量缩短高频回路路径，增加铜厚或加宽电源轨，确保散热与低阻抗接地。焊盘与过孔应符合制造商建议的焊接规范，保证可靠焊接。
五、可靠性与测试建议
- 建议在样机阶段做温升测试、长期老化、热循环与振动冲击测试，以验证在目标环境下的性能稳定性。
- 进行过流与重复冲击测试，确认在短时突发高流情况下电感不进入不可逆退磁或损坏状态。
- 确认回流焊温度曲线与焊接工艺兼容，避免高温或长时间回流造成磁胶或焊点劣化。
六、采购与封装信息
- 型号：YNR6028-330M。
- 品牌：YJYCOIN（益嘉源）。
- 标识参数：33 μH ±20%，DCR 185 mΩ，Irated 1.22 A，Isat 1.35 A，SMD 6×6 mm。
在量产前建议索取样品并参考厂方 Datasheet 获取完整的电气特性曲线、推荐焊盘和回流工艺资料。若有特殊环境或更高电流需求，可与供应商沟通定制或选型更高规格产品。

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.
