SMMS0630-100M是顺翔诺(SXN)推出的一款SMD型一体成型功率电感,针对中小功率电源电路的高效储能与滤波需求设计,凭借小型化封装、高饱和电流、低损耗等特性,成为消费电子、车载电子及工业控制领域的优选电感元件。
该电感聚焦中小功率电源的性能优化,解决传统绕线电感漏磁大、耐振动差、尺寸冗余等痛点。其核心价值体现在:通过一体成型工艺实现低EMI(电磁干扰)与高可靠性,同时以紧凑尺寸适配高密度PCB设计,满足现代电子设备“小型化、高效能”的发展趋势。
SMMS0630-100M的参数设计精准匹配电源电路的核心需求,各参数意义与应用逻辑如下:
电感值标称10uH,精度±20%(实际范围8uH~12uH),符合工业级电源设计的常规精度要求。该范围既保证储能滤波的基本功能,又通过放宽精度降低制造成本,适合对电感量一致性要求不极端的场景。
饱和电流定义为电感值下降30%时的直流电流,SMMS0630-100M的Isat为5.5A。若工作电流超过Isat,电感量会骤降,导致电源纹波增大、效率下降甚至失效。5.5A的Isat可支撑峰值电流达4A左右的连续工作(设计电流通常取Isat的70%~80%),满足多数中小功率电源的输出需求。
DCR标称68mΩ,反映线圈铜损。低DCR意味着电流通过时的功率损耗小(P=I²·R),可显著降低电源发热,提升转换效率(大电流场景下效果更明显)。
一体成型电感典型工作温度为-40℃125℃,覆盖消费电子(0℃85℃)、车载电子(-40℃~105℃)等场景的环境要求。
SMMS0630-100M采用SMD(表面贴装)封装,尺寸为7.3mm×6.6mm×3mm,具备以下物理优势:
相比同参数传统绕线电感,体积缩小约30%,可有效节省PCB空间,适配平板、智能穿戴、车载充电器等紧凑设备的布局需求。
采用粉末冶金工艺将磁芯与线圈压制为一体,无磁芯缝隙,因此:
SMMS0630-100M的性能适配多类电源电路,典型应用包括:
为保证电路可靠性与性能,使用时需注意以下几点:
实际工作电流应控制在Isat的70%~80%(≤4.4A),避免磁饱和导致电感量下降,影响电源纹波与效率。
综上,SMMS0630-100M以高性价比、高可靠性、小型化为核心优势,覆盖多类中小功率电源场景,是电子设备电源设计中平衡性能与成本的理想选择。
Request for quote
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.
