SMMS0650-470M功率电感产品概述

SMMS0650-470M是顺翔诺(SXN)推出的一款表面贴装(SMD)功率电感,针对中低功率电源电路设计,兼具紧凑体积与稳定电气性能,可满足便携式电子、IoT设备等场景的储能、滤波需求。以下从核心参数、封装特性、应用场景等维度展开概述。

一、核心电气参数解析

该电感的核心电气指标经过优化,平衡了储能能力与效率:

  1. 电感值与精度:标称电感值为47μH,精度标注为±20%(对应型号后缀“470M”中“M”代表±20%),满足大多数电源电路对电感值的基本要求,无需额外高精度滤波补偿。
  2. 电流承载能力:
    • 额定电流(Irms):2A(持续工作电流),在此电流下电感值变化控制在允许范围内,参数稳定;
    • 饱和电流(Isat):2.8A(峰值电流),当电流超过该值时,电感值下降幅度不超过30%,避免磁饱和导致输出电压突变,保障电路可靠性。
  3. 直流电阻(DCR):300mΩ(毫欧级),低阻值大幅降低铜损(工作时铜损=I²×R,2A持续电流下仅约1.2mW),减少发热同时提升整体电路效率。

二、封装与物理特性

  1. 封装类型:采用标准SMD表面贴装封装,适配自动化贴装产线,焊接可靠性高,兼容常规回流焊、波峰焊工艺。
  2. 尺寸规格:长×宽×高=7.1mm×6.6mm×5mm,紧凑体积可轻松嵌入小型化电子设备(如智能手表电源模块、便携式充电宝),不占用额外空间。
  3. 引脚设计:引脚间距符合行业标准,焊接时可有效避免桥连问题,提升生产良率。

三、典型应用场景

SMMS0650-470M的参数特性使其适用于以下场景:

  1. DC-DC转换器:作为升压/降压拓扑的储能电感,稳定输出电压,抑制纹波,适用于5V/12V电源转换电路。
  2. 便携式电子设备:如充电宝、蓝牙耳机充电盒、智能手环的电源管理模块,紧凑体积适配设备小型化趋势。
  3. IoT与智能家居:低功耗传感器节点、智能插座的滤波电路,减少电磁干扰(EMI),提升信号稳定性。
  4. 小型电机驱动:如玩具电机、微型泵的驱动电路,辅助电流调节,降低电机运行纹波。

四、性能优势总结

  1. 电流裕量充足:额定电流2A与饱和电流2.8A的差值,为峰值电流场景(如负载突变)提供可靠裕量,避免性能下降。
  2. 低损耗高效率:300mΩ DCR减少能量损耗,尤其适合对能效要求较高的便携式设备,延长电池续航。
  3. 环境适应性强:常规功率电感可满足-40℃~+85℃工作温度范围,适配工业级与消费电子的不同环境需求。
  4. 批量一致性好:±20%精度与成熟生产工艺,保证批量产品参数一致性,降低电路调试难度与成本。

五、品牌与可靠性保障

顺翔诺(SXN)作为专注功率电感的制造商,SMMS0650-470M经过多重质量管控:

  1. 环保合规:符合RoHS 2.0标准,无铅无镉,满足全球环保要求。
  2. 可靠性测试:通过高低温循环、振动测试、盐雾测试等,确保在复杂环境下长期稳定工作。
  3. 市场验证:已在多家消费电子、电源厂商批量应用,反馈性能稳定,性价比突出。

综上,SMMS0650-470M是一款平衡体积、电流、效率的高性价比SMD功率电感,适用于中低功率电源电路的储能与滤波需求,是小型化电子设备的理想选择。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
