SMSD0810-101M 功率电感产品概述

一、产品定位与核心身份

SMSD0810-101M是顺翔诺(SXN)推出的非屏蔽贴片功率电感,针对中小功率电子设备的电源电路设计,主打高性价比与稳定储能/滤波性能,适用于对EMI(电磁干扰)要求较低的应用场景。核心参数明确:电感值100μH(标识“101M”中,“10”为有效数字,“1”为10的幂次,“M”对应±20%精度),额定电流2.5A,直流电阻(DCR)220mΩ,封装为SMD贴片式SMSD0810规格。

二、关键性能指标详解

2.1 电感值与精度

电感标称值为100μH,精度±20%,覆盖90μH~110μH范围,满足多数电源电路的储能、滤波需求——例如DC-DC降压转换器中,电感值需稳定在目标区间以保证输出电压精度,该参数可适配主流电源拓扑。

2.2 电流能力

  • 额定电流(Irms):2.5A(有效值),指电感长期工作时,因铜损(I²×DCR)导致的温度上升不超过允许值(通常≤40℃)的最大电流,适合连续负载场景;
  • 饱和电流(Isat):2.5A(峰值),指电感值下降至标称值30%时的最大电流,说明该电感在2.5A峰值负载下仍能保持基本储能能力,避免因饱和导致电源输出异常。

2.3 直流电阻(DCR)

DCR为220mΩ,属于同规格电感中的低阻水平:铜损=I²×R,当负载电流为2.5A时,铜损仅为2.5²×0.22≈1.375W,发热可控,适合小体积设备的功率密度提升。

2.4 非屏蔽特性

采用非屏蔽设计,相比屏蔽型电感成本更低,且电感值一致性较好,但需注意:若应用场景对EMI敏感(如高频通信电路),需搭配EMI滤波元件使用;若为普通电源、LED驱动等场景,非屏蔽设计可降低整机成本。

三、设计特点与优势

3.1 贴片封装适配自动化生产

SMSD0810封装尺寸约为8.0mm(长)×10.0mm(宽)×6.0mm(高),引脚间距符合贴片元件回流焊要求,可兼容主流SMT生产线,提升生产效率。

3.2 耐温与可靠性

工作温度范围为-40℃~125℃(符合工业级标准),经过高低温循环、湿度(85℃/85%RH)测试,引脚焊接强度满足IEC 60068-2-20标准,适合户外、车载等恶劣环境应用。

3.3 环保合规

符合RoHS 2.0(无铅、无镉、无汞)与无卤要求,适配全球电子市场的环保准入标准,降低整机出口风险。

四、典型应用场景

SMSD0810-101M的参数特性使其适用于以下场景:

  1. DC-DC转换器:如5V转3.3V、12V转5V的降压电路,作为储能电感保证输出电压稳定;
  2. LED驱动电源:小功率LED灯带、台灯的恒流驱动电路,滤波纹波并提升效率;
  3. 移动电源/充电宝:升压电路(5V转9V/12V)的储能元件,适配快充需求;
  4. 消费电子:机顶盒、路由器、智能音箱的电源模块,满足中小功率供电;
  5. 车载辅助电路:汽车中控、氛围灯的电源转换,耐温性能适配车载环境。

五、选型参考建议

若需调整参数适配不同需求,可参考顺翔诺同系列产品:

  • 需更高电流(如3A):选择SMSD1012-101M(封装更大,电流提升);
  • 需更低EMI:选择屏蔽型电感(如SXN-SMD0810-101M-S);
  • 需更高精度(±10%):选择标识为“101K”的同封装型号;
  • 需更小体积:查看SMSD0608系列是否有同参数产品。

六、总结

SMSD0810-101M作为一款高性价比非屏蔽贴片功率电感,以100μH±20%电感值、2.5A额定电流、220mΩ低DCR为核心,适配中小功率电源电路的储能/滤波需求,兼顾自动化生产与环保合规,是消费电子、车载、LED驱动等领域的实用选型。

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.
