SMMS1360-330M功率电感产品概述

一、产品基本信息

SMMS1360-330M是顺翔诺(SXN)品牌推出的一款贴片式(SMD)功率电感,型号命名逻辑清晰:

  • “1360”对应封装尺寸(13.8mm×12.6mm);
  • “330M”表示额定电感值33μH,“M”代表精度±20%。

该产品采用表面贴装工艺设计,适配自动化生产线组装,是中功率电子电路中常用的储能与滤波核心元件。

二、核心电气性能参数

关键参数直接决定适用场景,需重点关注:

  1. 电感值与精度:额定33μH,公差±20%,满足大多数功率电路对电感值的常规要求,无需额外高精度匹配;
  2. 额定电流(Irms):4.5A,指电感持续工作时,直流电阻(DCR)产生的温升不超过行业常规允许范围(约50℃),确保长期可靠性;
  3. 饱和电流(Isat):7A,即电感值下降至额定值70%时的临界电流,具备较强抗电流尖峰能力,可应对电路启动、负载突变等场景;
  4. 直流电阻(DCR):56mΩ,低电阻设计有效降低铜损,提升电路效率,减少发热。

三、物理尺寸与封装特点

  • 尺寸规格:长13.8mm×宽12.6mm,厚度适配常规PCB贴装空间(官方未明确标注,可兼容主流功率电感厚度标准);
  • 封装优势:贴片式设计兼容主流贴片机吸嘴与贴装程序,回流焊温度曲线可参考SXN官方推荐(峰值温度240-250℃,持续时间30-60秒),避免焊接缺陷。

四、典型应用领域

结合电气参数,该电感适用于以下中功率场景:

  1. DC-DC开关电源:笔记本电脑、服务器、通信基站的降压/升压模块,满足10-50W输出功率的储能需求;
  2. LED驱动电源:大功率LED路灯、显示屏、工矿灯的恒流驱动电路,稳定电流输出,减少LED光衰;
  3. 车载电子:汽车中控、行车记录仪、车载充电模块的电源电路,耐受车载环境的温度与振动变化;
  4. 工业控制:PLC、变频器等工业设备的辅助电源,抗干扰能力强,适应工业现场复杂工况。

五、产品性能优势

相比同规格竞品,SMMS1360-330M具备以下核心优势:

  1. 低损耗高效:56mΩ的低DCR可将铜损降至最低,大电流持续工作时,有效降低电源模块发热与功耗;
  2. 抗饱和能力强:7A饱和电流远高于额定电流,可应对瞬间电流尖峰,避免电感饱和导致的电压跌落或电路失效;
  3. 成本可控:±20%精度兼顾性能与成本,适合消费电子、工业设备等批量生产领域;
  4. 可靠性稳定:顺翔诺品牌工艺控制严格,电感值、DCR一致性好,长期工作无明显参数漂移。

六、选型与应用注意事项

  1. 电流余量预留:持续工作电流不超过4.5A,瞬间尖峰不超过7A,建议留10%-20%余量;
  2. 温升控制:高温环境(如车载、工业现场)需优化PCB散热(增加铜箔面积),避免温升超标;
  3. 贴装工艺:严格遵循SXN官方回流焊曲线,防止封装开裂或电感值变化;
  4. 兼容匹配:需更高电流可选择同系列高电流版本,需更低DCR可咨询顺翔诺其他型号。

该产品以平衡的性能与成本优势,成为中功率电路设计中储能/滤波环节的实用选择。

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
