PZ2012D300-3R0TF是顺络电子(Sunlord)推出的0805封装功率型EMI抑制磁珠,针对高频电磁干扰(EMI)抑制与大电流承载需求优化设计,具备宽温适应性、高可靠性等特点,广泛应用于汽车电子、工业控制、大功率消费电子等领域。
该磁珠属于单通道贴片式功率磁珠,区别于普通小电流磁珠(额定电流通常≤1A),核心定位是在满足功率电路大电流传输的同时,精准抑制100MHz频段的电磁干扰。产品采用顺络成熟的软磁材料配方与贴片封装工艺,兼顾小体积与高功率密度,适配高密度PCB设计需求。
采用顺络定制化软磁材料,在100MHz频段阻抗一致性好,无明显峰谷漂移,确保EMI抑制效果可预测。
通过优化磁芯结构与材料配方,3A额定电流下无磁饱和现象,阻抗保持稳定,避免干扰抑制失效。
材料与封装工艺经过-55℃~+125℃温度循环测试(符合IEC 60068-2-14标准),高低温下参数无漂移,长期工作稳定性高。
0805封装(2.0mm×1.2mm)体积小巧,适配手机、车载PCB等高密度设计场景,节省布局空间。
25mΩ左右的低直流电阻,3A电流下功率损耗仅0.225W,不影响电源系统整体效率。
该产品凭借大电流、宽温、高频阻抗精准等优势,成为顺络功率磁珠系列中的经典型号,广泛应用于对EMI抑制与可靠性要求较高的场景,是电子系统电源滤波的理想选择。

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.
