顺络GZ1608D301CTF是一款小尺寸高频噪声抑制磁珠,核心用于衰减100MHz频段附近的电磁干扰(EMI),提升电路电磁兼容性(EMC)。产品针对中小电流电路设计,适配多领域电子设备的轻薄化、高密度布局需求,典型应用包括:
阻抗特性:100MHz下阻抗300Ω,误差±25%
磁珠阻抗为复阻抗(电阻+电感分量),100MHz频段以电阻分量为主——可将高频噪声能量转化为热能消耗(而非反射),避免干扰其他电路模块,是该频段EMI抑制的核心优势。
直流电阻(DCR):350mΩ低损耗设计
极小的直流压降(500mA电流下仅0.175V),适配电池供电等对功率损耗敏感的场景,不会因DCR过大导致电压跌落或额外发热。
额定电流:500mA(工作温度范围内)
指磁珠可持续通过的最大直流电流,若电流超限会导致DCR增大、温度升高,甚至损坏磁珠或周边电路,选型需严格匹配电路电流容量。
通道数:1通道单路设计
适用于单路电源/信号线路的独立噪声抑制,无需并联多路磁珠,简化电路布局。
封装尺寸:1608公制(对应0603英制)
尺寸约1.6mm×0.8mm×0.5mm,适配高密度PCB设计,满足现代电子设备小型化需求(如手机主板、智能手表模块)。
叠层结构优势
采用片式叠层工艺,无引线设计——寄生电感极低,高频特性优异,可减少信号传输中的寄生干扰;同时焊接可靠性高,适配回流焊、波峰焊等常规SMT工艺。
铁氧体材料特性
顺络自研高性能铁氧体材料,保证宽频率范围内的阻抗稳定性,且温度系数低,避免温度变化对阻抗特性的显著影响。
宽温工作范围:-55℃~+125℃
覆盖极端环境(如汽车发动机舱高温、北方低温地区户外设备),满足严苛场景的可靠性要求。
可靠性测试与环保认证
产品通过顺络内部及行业标准测试(温度循环、湿度循环、振动、冲击等),符合RoHS 2.0、REACH环保法规,采用无铅封装,适合出口及绿色产品设计。
顺络GZ1608D301CTF以小尺寸、宽温适应性、低DCR及精准的100MHz频段阻抗,成为中小电流电路EMI抑制的高性价比选择,广泛适配消费电子、汽车电子等多领域的电磁兼容设计需求。
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.
