YDFW1212T-153L01010是益嘉源(YJYCOIN)推出的双路低压共模滤波器,针对250V以下电源系统的电磁干扰(EMI)抑制需求设计,兼具体积紧凑、损耗低、可靠性强等特点,适用于多种民用及小型工业设备的电源滤波场景。
共模滤波器是EMC防护的核心元件,主要抑制电源线路中共模干扰(两条导线相对于地的同相位干扰)。YDFW1212T-153L01010的核心定位是250V系统的经济型滤波方案,通过双路电感设计,可同时对火线-零线(AC)或正-负极(DC)线路进行干扰抑制,既避免设备受外部干扰影响,又减少自身对外辐射,满足基本EMC要求。
产品参数直接决定应用适配性,以下是核心参数的落地解读:
双路独立滤波设计,无需额外并联元件即可适配双极电源(如AC220V火线/零线、DC24V正/负极),简化电路布局,降低设计成本。
电感量是滤波能力的核心指标:15mH在1KHz下的感抗约94Ω,可有效抑制1KHz~10KHz频段的共模干扰(如市电纹波、开关电源低频传导干扰)。该电感量平衡了滤波效果与体积,适合对低频干扰敏感的设备。
连续工作电压上限为250V(有效值),完全适配国内220V市电,以及DC250V以下低压直流系统(如工业DC24V、通信DC48V),无需担心过压风险。
绝缘耐压测试标准为1.5kV交流持续1分钟,满足GB 19212.1等低压设备绝缘要求,可承受瞬间过压(如雷击感应、电源浪涌),提升设备可靠性。
极低直流电阻意味着功率损耗小、发热低,连续工作无需额外散热,适合长时间运行设备(如家用路由器、工业PLC),同时降低设备能耗。
立式插装封装,体积紧凑,可直接焊接PCB板,适配空间紧张的设备(如机顶盒、小型变频器),不影响整体布局。
结合参数特点,该产品主要适用于以下场景:
益嘉源(YJYCOIN)是国内专注EMC元件的供应商,产品通过RoHS、CE认证;YDFW1212T-153L01010采用优质磁芯与漆包线,经老化测试,可保证长期稳定运行。
总结:YDFW1212T-153L01010是一款性价比高、适配性强的共模滤波器,适合250V以下低压系统的EMI抑制需求,尤其适用于对体积、损耗敏感的民用及小型工业设备。
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.
