SMMS0420-100M是顺翔诺(SXN)推出的小体积贴片式功率电感,针对高密度、中等功率电子电路设计,核心价值在于在紧凑封装下实现「高电流承载+低损耗」的平衡,适配消费电子、物联网终端等对尺寸敏感的场景。产品聚焦三大核心特性:小封装(4.6×4.2mm)、高饱和电流(2A)、低直流电阻(258mΩ),解决传统功率电感在便携设备中「体积大、电流不足、发热明显」的痛点。
SMMS0420-100M的参数直接决定应用适配性,需重点关注以下维度:
标称电感值为10μH,精度±20%(实际范围8μH12μH)。该精度满足DC-DC转换器、LED驱动等电路的常规需求(此类电路对电感精度要求多在±10%±30%),无需额外校准即可稳定工作。
标称258mΩ,属于同类小封装电感的低损耗水平。DCR直接影响铜损(P=I²×DCR),在1.6A额定电流下损耗仅约0.6W,可有效降低发热、提高电源转换效率。
SMMS0420-100M采用SMD表面贴装封装,尺寸为4.6mm×4.2mm(长×宽),具有以下优势:
结合参数特性,产品主要适用于以下场景:
相比同类竞品,SMMS0420-100M的核心优势:
产品经过严格可靠性测试,满足:
总结:SMMS0420-100M是专为中等功率、小体积场景设计的高性价比电感,在电流承载、损耗控制与封装尺寸上实现平衡,可广泛应用于消费电子、物联网领域,为电路提供可靠储能与滤波支撑。

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.
