SMMS1040-680MT功率电感产品概述

SMMS1040-680MT是顺翔诺(SXN)推出的一款表面贴装(SMD)功率电感,专为中小功率电源电路、滤波及储能场景设计,具备尺寸紧凑、饱和电流充足、损耗低等特点,可满足消费电子、车载电子、工业控制等领域的常规应用需求。

一、产品基本信息

  • 品牌:顺翔诺(SXN)
  • 产品型号:SMMS1040-680MT
  • 产品类型:SMD功率电感
  • 核心定位:中小功率电源储能/滤波电感

二、核心电气参数深度解析

该电感的关键参数直接决定应用范围与性能,具体解析如下:

  1. 电感值与精度:标称68μH,精度±20%。该范围可满足绝大多数电源电路(如DC-DC转换器、线性电源滤波)的设计需求,无需额外高精度匹配,同时控制成本。
  2. 额定电流(Irms):2A(有效值)。此为持续工作的最大允许电流,超该值会加剧发热,长期工作可能影响可靠性。
  3. 饱和电流(Isat):3.8A(电感值下降30%时的临界电流)。饱和电流远高于额定电流,为瞬态电流(如负载突变)提供充足余量,避免电感饱和导致电感值骤降,影响滤波或电源稳定性。
  4. 直流电阻(DCR):220mΩ。低DCR意味着自身损耗小(损耗公式:P=I²·R),额定电流2A时损耗仅0.88W,发热可控,提升电源整体效率。

三、封装与物理特性

SMMS1040-680MT采用SMD封装,物理尺寸为11.5mm×10mm(长×宽),厚度符合常规贴装标准。该尺寸紧凑,可有效节省PCB空间,适配高密度电路设计(如便携式电子、小型电源模块),支持自动化贴装工艺。

四、典型应用场景

结合参数特点,该电感适用于以下场景:

  1. DC-DC转换器:降压(Buck)、升压(Boost)电路的储能与滤波,支持2A以内中小功率输出;
  2. 电源滤波器:抑制电源纹波干扰,提升电路稳定性;
  3. LED驱动电路:配合恒流/恒压控制,为LED阵列提供稳定电流,避免频闪;
  4. 车载电子:车载充电器、仪表盘电源模块等(适配常规车载温度范围);
  5. 消费电子:手机、平板、笔记本电脑的电源管理单元(PMU)滤波。

五、产品性能优势

  1. 饱和电流余量充足:3.8A饱和电流远高于2A额定电流,应对瞬态负载更稳定,降低故障风险;
  2. 低损耗高性价比:220mΩ低DCR减少发热,提升效率,±20%精度平衡性能与成本;
  3. 尺寸紧凑易集成:SMD封装+11.5×10mm尺寸,适配自动化贴装,适合小型化产品;
  4. 品牌可靠性:顺翔诺产品经过常规可靠性测试(温度循环、振动),品质稳定。

六、选型与使用注意事项

  1. 电流匹配:持续电流≤2A,瞬态电流≤3.8A,避免饱和或过热;
  2. 精度适配:若需更高精度(如射频电路),需确认是否满足;
  3. 散热考量:高电流下需增加PCB散热铜箔,避免局部过热;
  4. 封装兼容性:贴装前确认焊盘尺寸与11.5×10mm匹配,避免虚焊;
  5. 温度范围:常规工作温度-40℃~+85℃,极端温度场景需咨询厂商。

该产品通过平衡性能、尺寸与成本,成为中小功率电源电路的高性价比选择,覆盖多数常规电子设备的电感需求。

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
