SMDRI127-101MT 产品概述
一、概述
SMDRI127-101MT 为顺翔诺（SXN）出品的磁胶屏蔽功率电感，封装形式为 SMD，外形尺寸 12.3×12.3mm，标称电感值 100μH，公差 ±20%。该器件定位于中大电流开关电源和电源滤波应用，兼顾较高饱和电流与屏蔽抑制性能。
二、主要规格参数
- 电感值：100μH（±20%）
- 额定直流电流（Irated）：1.7A
- 饱和电流（Isat）：3.5A
- 直流电阻（DCR）：220mΩ
- 类型：磁胶屏蔽电感（磁泄漏小）
- 尺寸：12.3 × 12.3 mm（SMD）
三、结构与材料说明
采用磁胶屏蔽结构，磁路及外壳处理有利于减小磁通泄漏与外部干扰，同时改善热传导。绕组与骨架材料针对功率应用优化，以兼顾低 DCR 与较高的饱和性能。
四、特性与优势
- 高 Isat（3.5A）保证瞬态电流承受能力；
- 额定电流 1.7A 适合中功率 DC-DC 变换器与滤波器；
- 屏蔽化设计减少对周边电路的磁干扰；
- 封装 SMD，便于自动贴装和回流焊接。
五、典型应用场景
适用于降压/升压 DC-DC 模块输入输出滤波、LED 驱动、电机驱动小功率段、消费及工业类电源滤波与能量储存。
六、设计与使用建议
- PCB 布局：开关节点与电容尽量靠近电感，走短、宽的铜箔并用过孔增加散热；
- 电流余量：建议实际工作电流留有裕度，长期工作最好低于额定电流以减少发热与避免接近饱和；
- 温升与散热：关注环境温度和散热路径，必要时增大铜箔面积或加散热层；
- 回流焊：兼容常规 SMD 回流工艺，建议参照厂商提供的焊接曲线执行。
七、可靠性与检验要点
关注电感在 DC 偏置下的电感衰减与温升，进行温度循环与焊接热稳定性测试；检查外壳与焊盘的机械可靠性以保证在震动、冲击工况下的稳定性。
八、选型与采购提示
在选型时以实际工作电流、允许电感衰减与尺寸限制为主。订购时注明型号 SMDRI127-101MT、数量及封装要求，并与供应商确认大批量出货的一致性与可追溯的质量报告。
如需更详细的电气特性曲线（如 L vs. I 曲线、频率特性、回流焊曲线及可靠性测试报告），建议联系顺翔诺厂商获取完整规格书与样品测试数据。

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.
