SMMS1770-101M是顺翔诺(SXN)推出的贴片式功率电感,针对中大功率电子电路的储能、滤波需求设计,兼具紧凑尺寸与稳定电气性能,适合自动化贴装生产,广泛覆盖电源、车载、工业控制等领域。产品采用SMD封装,尺寸仅17.5×17.15×7mm,在有限PCB空间内可承载5.3A连续工作电流,能满足多数中功率设备的电源转换场景需求。
该电感的关键参数直接决定应用适配性,以下是核心参数的实际意义与价值:
电感值为100μH(±20%),属于中功率电感常见规格——100微亨的电感量可有效储存电能,满足DC-DC转换器、LED驱动等电路的储能需求;±20%的精度平衡了成本与性能,适合对电感值波动要求不高的通用场景(若需高精度,需结合电路设计额外补偿)。
DCR为118mΩ,即直流下的电阻值。铜损(P=I²×DCR)是功率电感的主要损耗,118毫欧的阻值在同规格中属于中等偏优——5.3A下铜损约3.3W,既控制了损耗,又通过线径设计保证了电流承载能力。
SMMS1770-101M采用SMD贴片封装,具体尺寸为:长17.5mm×宽17.15mm×高7mm,优势在于:
结合参数特性,该电感的适配场景包括:
为保证长期稳定工作,需注意:
SMMS1770-101M凭借紧凑尺寸、稳定电流承载能力,成为中功率电源电路的高性价比选择,适配多数通用电子设备的电源模块设计需求。

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.
