SMMS0630-150M是顺翔诺(SXN)推出的一款表面贴装(SMD)一体成型功率电感,针对中低功率DC-DC转换电路设计,平衡了小体积、低损耗与高电流承载能力,适用于消费电子、工业控制、汽车电子等多领域的电源模块需求。
该产品聚焦中功率密度电源设计,解决传统绕线电感体积大、EMI辐射高的痛点,主要应用于:
SMMS0630-150M的核心参数针对电源转换效率与稳定性优化,关键指标如下:
电感值为15uH ±20%,覆盖大多数DC-DC buck/boost电路的电感范围(10uH-22uH为消费电子快充常用区间),±20%的精度可适配负载波动下的电路稳定性,无需额外复杂补偿设计。
饱和电流为4.5A,指电感值下降不超过20%时的最大直流电流。该指标直接决定电源峰值负载能力——例如智能手机快充(5V/3A)的峰值电流约4A,4.5A的Isat可保证电感不进入饱和区,避免转换效率骤降或电压纹波增大。
直流电阻为115mΩ,属于同类封装中的低阻水平。低DCR可显著降低导通损耗(损耗公式:P=I²×DCR),以3A工作电流为例,损耗仅约1.035W,有效减少电源模块发热,提升整体效率。
一体成型工艺支持100kHz-5MHz的开关频率范围,适配目前主流DC-DC控制器的工作频率,兼顾高频下的磁损耗控制。
封装规格为7.3mm(长)×6.6mm(宽)×3mm(高),属于0630封装系列(行业习惯以“长度×宽度”简化命名),比传统绕线电感体积缩小约30%,适合高密度PCB布局(如手机主板的电源模块区域)。
采用磁粉芯一体压制技术,相比绕线电感具有三大优势:
SMD封装支持标准回流焊工艺,适配自动化贴片生产线,无需额外手工焊接,提升生产效率与产品一致性。
工作温度覆盖**-40℃125℃**,满足工业级(-40℃85℃)与汽车级(-40℃~125℃)的环境要求,例如车载电源在低温启动或高温暴晒下仍能稳定工作。
低DCR减少发热,结合磁粉芯的热稳定性,产品平均无故障时间(MTBF)超过10万小时,适合长期运行的电源设备。
表面采用抗氧化涂层处理,可抵抗潮湿、盐雾等环境侵蚀,延长户外或高湿场景下的使用寿命。
以智能手机快充电源为例,SMMS0630-150M配合TI的TPS61088 buck控制器,可实现9V/2A的快充输出:
SMMS0630-150M通过一体成型工艺、低阻设计与小体积封装,解决了中低功率电源的效率、体积与可靠性痛点,是消费电子、工业控制等领域电源模块的高性价比选择。顺翔诺(SXN)作为专业电感制造商,该产品已通过RoHS认证,符合环保要求,可批量应用于各类量产设备。
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.
