SMDRH104R-100MT是顺翔诺(SXN)推出的一款磁胶屏蔽式表面贴装功率电感,专为中小功率DC-DC变换电路设计,兼顾高电流承载能力与低电磁干扰(EMI)特性,广泛适配消费电子、车载电子及工业电源模块等场景。以下从核心特性、参数、应用等维度展开概述。
该电感属于中小功率级磁胶屏蔽电感,核心优势是“低EMI+高电流密度”,典型应用覆盖三类场景:
其磁胶屏蔽结构可有效降低对外辐射干扰,适配对EMI敏感的电路设计(如模拟信号电路周边)。
关键参数直接决定产品适用场景,需重点关注以下指标:
参数名称 规格值 意义说明 电感值 10uH±20% 满足多数DC-DC电路的电感量需求,±20%精度在量产中易匹配,降低BOM成本 额定电流(Irms) 3.8A 25℃环境下,电感自身温升≤40℃的连续工作电流,设计需留20%~30%余量 饱和电流(Isat) 5.6A 电感值下降至额定值70%时的峰值电流,是瞬间过载的关键安全指标 直流电阻(DCR) 35mΩ 低铜损设计,可减少功率损耗(P=I²R),提升电源转换效率 封装尺寸 10.4×10.3mm 近似1010封装,PCB布局空间友好,适配主流回流焊设备注:工作温度范围默认适配-40℃~125℃(磁胶屏蔽电感常规宽温特性),满足车载/工业环境需求。
该产品采用磁胶屏蔽+树脂封装结构,区别于传统金属屏蔽电感的核心优势:
顺翔诺(SXN)作为国内专注功率电感的制造商,该产品通过以下工艺确保可靠性:
SMDRH104R-100MT以“磁胶屏蔽低EMI+高电流密度+低DCR”为核心竞争力,是中小功率DC-DC变换场景的高性价比选择,尤其适合对电磁干扰敏感、需宽温适配的应用。其封装尺寸与参数匹配性,可直接替代部分进口同规格电感,降低成本的同时保证性能稳定。

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.
