YPRH1209-331M是益嘉源(YJYCOIN)推出的12×12×10mm贴片式磁胶屏蔽功率电感,专为中等功率密度的电子设备设计,核心功能是实现电路储能、滤波及纹波抑制。其磁胶屏蔽结构可有效降低漏磁干扰,适合对电磁兼容性(EMC)要求较高的场景,典型应用包括:
电感标称值为330μH(标识“331M”中,“33”为有效数字,“1”代表10¹倍,“M”对应±20%精度),满足一般工业级设备对电感误差的要求。该电感值适配20kHz~200kHz工作频率的DC-DC电路,可平衡纹波抑制与体积成本。
额定电流为1.28A(通常指“温升电流”,即电感本体温度上升≤40℃时的最大持续电流)。若工作电流超过此值,磁芯易进入饱和状态,电感值会显著下降(可能降至标称值50%以下),导致电路纹波增大、效率降低。设计时建议保留20%~30%电流裕量,避免饱和风险。
绕组直流电阻为386mΩ,是衡量电感功耗的核心参数。以1.28A额定电流计算,静态功耗约0.63W(I²R=1.28²×0.386),在同类1210封装电感中处于较低水平,有助于提升电源转换效率,减少设备散热需求。
采用SMD 12×12×10mm标准贴片封装,体积小巧,兼容自动化贴装设备(回流焊、波峰焊),适合高密度PCB布局。封装尺寸符合IPC标准,可直接替换同类进口电感,降低供应链成本。
磁胶屏蔽替代传统金属屏蔽壳,优势显著:
绕组采用高强度漆包线,磁芯为高性能铁氧体材料,可承受多次回流焊(峰值260℃,时间≤30s),长期工作可靠性达10万小时以上,符合RoHS 2.0环保标准(无铅无镉)。
益嘉源(YJYCOIN)是国内专注功率电感研发生产的企业,产品覆盖消费电子、工业、车载等领域。YPRH1209-331M通过ISO 9001认证,批量一致性好(电感值偏差控制在±15%以内,优于标称±20%),支持小批量样品测试与定制化需求。
该产品凭借紧凑体积、低EMI、高可靠性,成为中等功率电子设备的优选电感方案。
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.
