YSPI0730-100M是益嘉源(YJYCOIN) 推出的一款一体成型贴片功率电感,专为中等功率电子电路设计,兼顾小尺寸、低损耗与高可靠性,适用于消费电子、车载、工业控制等领域的电源转换及滤波场景。
该电感的关键参数围绕“功率适配性”与“效率优化”设计,具体如下:
标称电感值为10μH,精度±20%(即实际电感值范围8μH~12μH),满足大多数DC-DC转换器、滤波电路的电感量需求——既避免过高精度带来的成本冗余,又能稳定匹配电路拓扑结构。
额定电流为4A(持续工作电流),是指在环境温度≤125℃时,电感本体温度上升不超过35℃的最大电流。若实际工作电流低于4A,电感发热可控;若短时间过载(如脉冲电流),需结合散热设计评估,但长期超额定电流会导致电感值漂移、DCR增大,甚至损坏。
直流电阻为60mΩ(典型值),属于同类小尺寸电感中的低损耗水平。DCR直接影响导通损耗(P=I²·R),60mΩ的阻值可将4A电流下的导通损耗控制在0.96W以内,显著提升电源转换效率,减少系统发热。
YSPI0730-100M采用SMD贴片封装,具体尺寸为7.3mm(长)×6.6mm(宽)×3mm(高),属于紧凑型封装:
结合参数特性,该电感广泛应用于以下场景:
综上,YSPI0730-100M是一款兼顾性能、尺寸与成本的实用型功率电感,可满足多数中等功率电子设备的电源设计需求。

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.
