PBY201209T-300Y-N是奇力新(Chilisin) 推出的一款0805封装电源滤波磁珠,专为电源线路的电磁干扰(EMI)抑制设计,兼顾低损耗、高电流承载能力与宽温适应性,适用于消费电子、工业控制、车载等多领域的电源滤波场景。
奇力新作为全球知名的磁性元器件制造商,专注于磁珠、电感等产品的研发与生产,其电源磁珠系列以高可靠性、精准阻抗匹配著称。PBY201209T-300Y-N属于该品牌的中功率电源磁珠产品线,采用单通道设计,针对100MHz频段的常见EMI干扰进行优化,满足紧凑PCB布局与恶劣环境下的滤波需求。
该产品的核心参数围绕滤波效果、电源损耗、电流承载、环境适应性四大维度设计,具体如下:
磁珠的核心作用是通过高频阻抗衰减干扰信号,该产品在100MHz(电子设备中常见的EMI干扰频段,如开关电源噪声、射频干扰)下的阻抗为30Ω,误差范围±25%(即22.5Ω~37.5Ω),既保证了批量生产的一致性,又能有效抑制该频段的噪声传输,避免干扰敏感电路(如射频模块、MCU)。
DCR是磁珠在直流通路下的电阻,直接影响电源效率与发热。15mΩ的低DCR意味着:
额定电流为磁珠持续工作的最大电流(无明显性能衰减),4A的承载能力满足中功率电源线路需求(如12V/4A电源、5V/4A快充模块),避免因电流过载导致磁珠饱和(阻抗下降、滤波失效)。
采用0805英制封装(对应2.0mm×1.2mm公制尺寸),体积小巧,适合高密度PCB布局(如智能手机主板、车载中控模块),可有效节省空间。
宽温设计覆盖了工业级(-40℃~+85℃) 与车规级(-40℃~+125℃) 需求,可在极端环境下(如高温车间、车载冬季低温启动)稳定工作,无需额外降额使用。
该产品因参数特性,广泛应用于以下领域:
该产品以高性价比、稳定性能成为中功率电源滤波的主流选择,可满足多数电子设备的EMI抑制与电源效率需求。

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.
