BMRA000404202R2MA1是奇力新(Chilisin)推出的一款磁胶屏蔽贴片功率电感,专为中小功率电源电路的储能、滤波及EMI抑制设计,具备小体积、低损耗、高可靠性等核心优势,可满足消费电子、通信设备等领域的高密度布局需求。
该电感聚焦高集成度电源系统的核心需求,核心特性可概括为:
电感值为2.2μH ±20%,属于中低电感量范畴,适配DC-DC降压转换器(如5V→3.3V、12V→5V)的储能需求。±20%的精度覆盖了生产一致性波动,在电源滤波、纹波抑制场景下无需额外校准,降低设计复杂度。
低DCR是功率电感效率的核心指标:58mΩ的电阻值意味着在3A电流下,导通损耗仅为(I^2R=3^2×0.058=0.522W),发热控制优异,可简化散热设计(无需额外散热片)。
采用磁胶屏蔽结构:相比非屏蔽电感,磁胶包裹磁芯可大幅减少漏磁,降低对周边电路的电磁干扰;同时磁胶的柔韧性提升了电感的抗振动、抗冲击能力,适配回流焊等表面贴装工艺。
该电感采用4.1×4.6mm SMD贴片封装,符合紧凑尺寸要求,厚度通常≤2mm(具体需结合 datasheet),适配高密度PCB布局。内部结构为:
基于参数与特性,该电感适用于以下场景:
奇力新作为全球知名电感制造商,具备成熟的生产工艺与质量管控体系:
BMRA000404202R2MA1以小体积、低损耗、高EMI抑制为核心优势,精准匹配中小功率电源系统的设计需求,尤其适合消费电子、通信等对空间与噪声敏感的领域。其额定电流与饱和电流的匹配设计,进一步提升了应用稳定性,是高密度电源布局的优选电感方案。

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.
