SMMS0650-680M 功率电感产品概述

一、产品核心定位与应用场景

SMMS0650-680M是顺翔诺(SXN)推出的SMD贴片式功率电感,针对中低功率DC-DC转换场景优化设计,兼具小尺寸、低损耗与稳定电流承载能力,核心定位为「小封装高性价比功率电感」,可替代同类0650封装规格产品,广泛适配消费电子、车载电子及物联网设备等领域的电源管理需求。

二、关键技术参数解析

1. 电感特性

标称电感值为68μH,精度±20%,符合功率电感的常规精度要求;在额定电流范围内,电感值变化率控制在≤10%,确保电路输出电压稳定,避免因电感漂移导致的电源波动。

2. 电流承载能力

  • 额定电流(Irms)1.5A:长期连续工作的最大允许电流,此时电感无明显饱和趋势,可保障设备稳定运行;
  • 饱和电流(Isat)2A:电感值下降30%时的极限电流,设计时需留有余量,避免峰值电流接近该值导致电路失真(如输出电压跌落、纹波增大)。

3. 直流电阻(DCR)

DCR为442mΩ,属于同封装规格中的低损耗水平——每1A电流下损耗约0.442W,可有效降低电源转换过程中的铜损,减少设备发热,提升整体效率2%-3%。

三、封装与物理特性

SMMS0650-680M采用SMD贴片封装,具体尺寸为:

  • 长×宽×高:7.1mm×6.6mm×5mm
  • 兼容国际标准0650封装(部分厂商标注为6.5×7×5mm)

引脚采用镀锡工艺,焊接兼容性好,可适配常规SMT回流焊、波峰焊工艺;封装材料具备耐温性(典型工作温度范围**-40℃~+125℃**),适合复杂环境下的长期使用。

四、性能优势与可靠性

1. 电流-尺寸平衡

在7.1×6.6mm的小封装内实现1.5A额定电流,兼顾空间紧凑性与电流承载能力,适合便携式设备的高密度布局(如手机快充适配器、无线耳机充电盒)。

2. 低损耗设计

442mΩ的DCR显著降低电源转换铜损,尤其在小功率场景下(如5V转3.3V电路),可减少发热,延长设备使用寿命。

3. 可靠性保障

顺翔诺品牌电感经过老化测试、温湿度循环测试(-40℃~+125℃,循环100次)、振动测试(10-2000Hz,加速度2g),平均无故障时间(MTBF)达10万小时以上,满足消费电子及车载电子的长期使用要求。

五、典型应用场景

  1. 消费电子电源:手机快充适配器(5V/2A、9V/1.5A档位)、无线耳机充电盒、智能手表电源模块;
  2. 小型DC-DC转换器:12V转5V/1A、5V转3.3V/1.2A的降压电路(常见于路由器、机顶盒);
  3. 车载电子:车载USB充电器(5V/2A)、仪表盘辅助电源、行车记录仪电源模块;
  4. 物联网设备:传感器节点(温湿度/运动传感器)、智能家居设备(智能灯泡、智能插座)的电源管理。

六、选型与使用注意事项

  1. 电流匹配:连续工作电流≤1.5A,峰值电流≤2A(饱和电流),避免长期过载;
  2. 温度控制:高温场景(如车载)需降额使用(每升高10℃,电流降额10%);
  3. 焊接工艺:回流焊峰值温度≤245℃(时间≤10s),避免过热损坏磁芯;
  4. PCB布局:电感靠近DC-DC开关管与输出电容,减少走线长度(降低寄生电感),避免与高频信号线并行(减少EMI)。

SMMS0650-680M凭借小封装、低损耗、稳定电流承载能力等优势,成为中低功率电源管理场景的优选功率电感,可广泛适配多种电子设备的设计需求。

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
