PBY201209T-121Y-N是奇力新(Chilisin) 推出的0805封装贴片式电源磁珠,属于高频电磁干扰(EMI)抑制核心器件。其核心作用是过滤电源线路中的传导噪声,同时通过低直流电阻(DCR)减少功率损耗,兼顾电气性能与小尺寸设计,适配消费电子、工业控制等多领域的高密度PCB布局需求。
该磁珠的参数精准匹配电源噪声抑制场景,核心指标及意义如下:
阻抗为120Ω±25%@100MHz:
100MHz是开关电源(如DC-DC转换器、LDO)产生的典型高频噪声频段,120Ω的阻抗值可有效衰减此频段的干扰信号,帮助电路满足电磁兼容性(EMC)标准;±25%的误差范围符合工业级器件的常规精度要求,保证批量应用的一致性。
直流电阻仅40mΩ:
低DCR是该产品的核心优势——在3A额定电流下,功率损耗仅为(I^2R = 3A^2×0.04Ω = 0.36W),大幅减少发热,避免因热损耗导致的电路效率下降或器件老化,尤其适合电池供电的便携式设备。
额定电流为3A:
持续工作电流覆盖中小功率电源场景(如12V/3A、5V/3A模块),满足多数消费电子、工业设备的供电需求;短时间峰值电流可高于额定值(需结合降额设计),适配瞬态负载波动。
单通道设计:
结构简单可靠,无交叉干扰风险,适合单独的电源线路滤波,也可通过并联扩展电流(需注意阻抗匹配)。
PBY201209T-121Y-N采用0805英制贴片封装(对应公制2012),尺寸为(2.0mm×1.2mm×0.9mm)(长×宽×高),具备以下特点:
该磁珠的参数特性使其覆盖多领域电源滤波需求,典型场景包括:
工作温度为**-55℃+125℃**,远超常规商业级器件(0℃+70℃),可适应高原、沙漠、严寒地区的极端环境。
符合RoHS无铅环保标准,适配现代电子制造的无铅回流焊流程,避免有害物质残留。
低DCR减少发热,结合磁珠材料的抗老化特性,确保长期工作(5年以上)的电气性能稳定,降低售后维护成本。
PBY201209T-121Y-N作为奇力新的高性价比电源磁珠,以低DCR、3A额定电流、宽温范围为核心优势,精准匹配电源线路的EMI抑制与小功率供电需求,适合消费电子、工业控制等多领域的高密度PCB设计。其平衡的电气性能与可靠性,使其成为中小功率电源滤波的理想选择。
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.
