PSA MCS0420-100MN1是信昌电陶(PSA)推出的贴片式功率电感,专为低中功率直流变换、滤波电路设计。型号中:
该电感适配自动化贴片生产工艺,广泛应用于消费电子、车载电子、工业控制等领域的电源电路,是紧凑布局场景的高性价比选择。
核心参数直接决定适用场景,需重点关注以下4项:
标称电感值10μH,精度±20%(实际范围8μH~12μH)。此精度满足大多数功率电路的滤波、储能需求——无需过高精度即可实现稳定的电压变换,同时降低成本。
1.2A(有效值)。额定电流是指电感连续工作时,自身温升不超过行业常规标准(≤40℃) 的最大电流。选型时需优先匹配:若工作电流超过额定值,电感会因过热导致性能下降甚至损坏。
2.2A。饱和电流是磁芯磁化饱和、电感值下降至初始值30%时的电流(厂家标准)。该值远高于额定电流(1.83倍),意味着短时过载(如启动瞬间、脉冲电流) 下仍能保持基本电感特性,避免电路性能突变。
256mΩ(毫欧)。DCR是电感绕组的直流电阻,直接影响功耗:1.2A工作电流下,功耗约0.37W(P=I²×R),低DCR设计可减少电源损耗,提升电路效率。
该电感采用紧凑SMD封装,规格为4.0mm×4.6mm×2.0mm(长×宽×高),适配高密度电路板:
基于小体积、中功率、高饱和电流的特点,主要应用于:
降压(Buck)、升压(Boost)电路的储能电感,适配5V→3.3V、12V→5V等低中压变换(如手机充电模块、路由器电源)。
抑制开关电源纹波噪声,提升输出电压稳定性(如LED驱动电源、工业电源滤波)。
1-3W LED串/并联驱动的电感滤波,支持台灯、小夜灯等便携照明设备。
车载USB充电、中控屏电源等低功率场景(需配合-40℃~85℃车载级温度范围)。
PSA MCS0420-100MN1凭借小体积、高可靠性、适配多场景的特点,是消费电子、车载电子等领域电源电路的高性价比选择,可满足批量生产与紧凑设计需求。
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.
