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。
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。
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。
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。
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。
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。
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。
SMSD0810-101M的参数特性使其适用于以下场景:
若需调整参数适配不同需求,可参考顺翔诺同系列产品:
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。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
