SMMS1040-150M 功率电感产品概述
SMMS1040-150M是SXN顺翔诺推出的紧凑型表贴功率电感，针对中功率大电流场景设计，以11.5×10×4mm的小体积实现了6A额定电流与7A饱和电流的性能，适配多数DC-DC转换、LED驱动等电路需求。
一、核心参数与产品定位概览
该产品的核心参数直接匹配中功率电子设备的需求，具体如下表：
参数类别 具体规格 备注说明 电感值 15μH ±20% 覆盖中功率Buck电路主流范围 额定电流（Ir） 6A（典型温升≤40K） 连续工作稳定电流 饱和电流（Isat） 7A（电感值降30%） 过载裕量保障 直流电阻（DCR） ≤55mΩ 低铜损提升效率 封装尺寸 11.5×10×4mm（SMD） 紧凑型表贴适配自动化生产 品牌 SXN（顺翔诺） 专注功率电感研发生产产品定位为中功率表贴功率电感，解决了传统插件电感体积大、装配效率低的问题，适合高密度PCB设计。
二、关键性能指标解析
1. 电感值与精度的适配性
15μH±20%的电感值是低压大电流DC-DC转换器（如12V转5V、24V转12V）的主流选择：电感值过低会导致纹波过大，过高则增加体积成本；±20%精度满足工业/消费电子的设计裕量，无需额外预留空间，平衡了性能与成本。
2. 电流特性的安全裕量
- 额定电流6A：环境25℃时表面温升≤40K（温度≤65℃），确保长期连续工作无过热风险；
- 饱和电流7A：电流达7A时磁芯开始饱和（电感值降30%），比额定电流高1A，为启动瞬态、负载突变等过载场景提供缓冲，避免电路故障。
3. 低DCR的效率优势
55mΩ的直流电阻是核心优势：6A电流下铜损仅1.98W（P=I²R），远低于同封装竞品，可提升DC-DC效率0.5%-1%，适合LED驱动、车载电源等对效率敏感的场景。
三、封装与典型应用场景
1. 紧凑型SMD封装的优势
11.5×10×4mm封装具有：
- 体积紧凑：比插件电感缩小30%，适配高密度PCB；
- 装配高效：支持回流焊，集成自动化生产线，降低装配成本；
- 兼容性强：符合IPC标准，适配多数PCB焊盘设计。
2. 典型应用场景
- 电源模块：工业PLC、服务器辅助电源的DC-DC降压电路；
- LED驱动：工矿灯、路灯等大功率LED的恒流驱动；
- 车载电子：车载信息娱乐系统、ADAS传感器供电（适应-40℃~125℃）；
- 消费电子：高端快充充电器、移动电源的大电流输出模块。
四、品牌与可靠性保障
SXN顺翔诺专注功率电感研发，SMMS1040-150M通过以下设计保障可靠性：
- 优质材料：高磁导率铁硅铝磁芯+高导电铜线，性能一致性好；
- 可靠性测试：温度循环（-40℃~125℃，500次）、振动测试（10-2000Hz，1G）、老化测试（125℃，1000小时），符合工业级标准；
- 环保合规：RoHS/REACH认证，无铅焊接兼容，适配全球市场。
总结
SMMS1040-150M以紧凑封装实现“大电流、低损耗、高可靠性”的平衡，是工业、车载、消费电子等领域中功率设备的理想电感选择，既满足自动化装配需求，又保障电路稳定与效率。

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.
