MCS0420-2R2MN2是PSA信昌电陶推出的表面贴装(SMD)功率电感,核心参数精准覆盖中低功率电源电路需求,具体如下:
低损耗高转换效率
52mΩ的DCR在同封装电感中处于优势水平:当工作电流为3A时,功率损耗仅约0.468W(计算方式:I²R=3²×0.052),可有效降低电源模块热损耗,提升能效,尤其适合电池供电的便携设备。
充足电流余量
额定电流3A覆盖多数中低功率场景(如5V/3A充电模块),饱和电流5A可应对负载突变、启动瞬间的峰值电流(如手机快充启动时的瞬时电流),避免电感饱和导致电感值骤降,保障电路稳定性。
小型化设计
4.0×4.6×2.0mm的紧凑封装,可节省PCB板空间30%以上(对比传统5×5mm封装),适配消费电子轻薄化趋势(如无线耳机、智能手表的电源模块)。
宽温可靠性
产品设计兼顾-40℃~+85℃工作温度范围(具体可参考PSA官方 datasheet),满足不同环境下的稳定工作需求(如户外传感器、车载辅助模块)。
该电感采用SMD表面贴装封装,焊盘尺寸符合行业标准,支持回流焊、波峰焊等自动化生产工艺,适合批量制造。主要适用场景包括:
PSA信昌电陶是国内专业被动元器件制造商,专注电感研发10余年,品质管控体系完善:
该产品凭借“小体积、低损耗、高电流余量”的特点,成为消费电子、小型工业设备电源电路的高性价比选择。

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.
