SMRH3D28-100MT是顺翔诺(SXN)推出的表面贴装(SMD)磁胶屏蔽功率电感,专为中小功率直流-直流(DC-DC)转换、滤波及储能场景设计。作为常规功率电感型号,其核心优势聚焦于三大维度:
额定电感值为10μH,精度±20%,覆盖大多数常规电源电路的滤波、储能需求(如5V/1A输出的DC-DC模块)。±20%的精度范围无需额外匹配高精度电路,兼顾成本与实用性,适合工业控制、消费电子等领域的批量应用。
饱和电流为1.05A(电感值下降30%时的直流电流),是功率电感的核心性能指标——当电路电流超过该值时,磁芯进入饱和状态,电感值骤降导致滤波/储能能力失效。1.05A的Isat可稳定支撑1A左右的连续工作电流,适配中小功率电源模块的负载需求。
直流电阻为145mΩ,反映电感绕组的电阻损耗。1A电流下的功率损耗约0.145W(I²R),相比同电感值的非低DCR型号,发热降低约30%,可有效提升电源转换效率,减少散热设计成本。
采用磁胶屏蔽,通过包裹磁芯的磁胶材料抑制电磁场泄露,相比裸磁芯电感,近场辐射强度降低约40%,可避免对周围敏感电路(如MCU、传感器)的干扰,提升系统整体稳定性。
SMRH3D28-100MT采用表面贴装(SMD)封装,适配主流回流焊、波峰焊工艺,支持自动化生产线快速组装。磁胶屏蔽结构紧凑,相比同参数的非屏蔽电感,体积缩小约15%,可节省PCB布局空间,适合智能手机、智能音箱等小型化设备的高密度电路设计。
封装引脚设计牢固,抗振动冲击能力符合IEC 60068-2-6(振动测试)标准,可稳定应用于移动设备或工业现场环境。
手机充电器、移动电源、蓝牙耳机充电盒的DC-DC升压/降压电路。10μH电感满足1A输出的储能需求,低DCR减少充电发热,磁胶屏蔽避免干扰音频模块。
小型PLC(可编程逻辑控制器)、传感器节点的电源滤波电路。1.05A的Isat适配1A以内工作电流,屏蔽结构减少对模拟传感器的电磁干扰,提升信号采集精度。
智能路由器、智能门锁的电源模块。紧凑SMD封装适配设备小型化,宽温特性(-40℃~+125℃)满足不同环境温度下的稳定工作。
车载USB充电器、行车记录仪的电源转换电路。磁胶屏蔽符合车载EMC标准,抗振动特性适配车辆行驶中的冲击环境。
SMRH3D28-100MT以平衡的性能与成本优势,成为中小功率电源电路的通用型电感选择,适配多领域电子设备的小型化、高效能需求。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
