YSPI0730-220M是益嘉源(YJYCOIN)推出的SMD表贴式一体成型功率电感,专为中小功率电源电路的储能、滤波及EMI抑制需求设计。其核心优势体现在「参数平衡」与「结构可靠性」双重维度:
标称22μH,精度±20%,覆盖工业级应用对电感量的常规需求——无需额外高精度筛选,即可满足DC-DC转换器、LED驱动等电路的储能/滤波要求。
3A(连续工作电流),在额定电流下电感值变化率≤30%(行业标准),确保电路稳定;若需峰值电流,可参考厂家给出的饱和电流(通常高于3A),适配脉冲负载场景(如LED频闪驱动)。
130mΩ,属于同规格电感的低损耗水平:3A工作下铜损仅1.17W(I²R计算),有效提升电源转换效率,减少模块发热(尤其适合小体积产品)。
7.3×6.6×3mm(长×宽×高),紧凑体积适配高密度PCB布局,是车载充电器、路由器等小型化产品的理想选择。
磁芯采用铁氧体合金粉末压制,无气隙设计使磁通量集中在内部,显著降低向外辐射的EMI,避免对周边敏感元件(如MCU、传感器)造成干扰,符合车载EMC标准(ISO 11452)。
磁芯与线圈一体化成型,无松动风险,可承受10G以上振动(IEC 60068-2-6标准),适配车载、工业控制等 harsh环境(如机器人关节驱动)。
SMD封装采用高温焊端,兼容无铅回流焊工艺(峰值温度≤260℃/10s),焊接后焊点强度高,减少虚焊、脱焊风险。
YSPI0730-220M的参数特性适配以下核心场景:
若电路连续电流接近3A,建议环境温度>85℃时降额至2.5A以内,避免电感过热导致参数漂移;峰值电流需参考厂家饱和电流参数(通常≥4A)。
严格遵循回流焊曲线:预热温度150180℃(60s)、峰值温度240260℃(10s),禁止手工焊接(易导致磁芯开裂)。
环境温度>100℃时,需在PCB电感焊盘下敷铜(≥2层),或贴小型散热片,防止过热。
该产品通过了RoHS认证,符合环保要求,是中小功率电源设计的高性价比选择。
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.
