YSPI0750-4R7M是益嘉源(YJYCOIN)推出的SMD贴片一体成型功率电感,专为中大功率DC-DC转换、滤波及储能场景设计。产品以“小体积承载大电流、低损耗提升效率”为核心,适配消费电子、通信、工业控制等多领域的功率电路需求,是替代传统线绕电感的高性价比方案。
电感标称值为4.7μH,精度±20%,满足多数功率电路对电感量的基本要求(如降压/升压转换器的储能电感)。该精度范围在量产中一致性良好,无需额外筛选即可稳定匹配电路设计。
额定电流为6.5A(直流电流,DC),指电感在25℃环境温度下,温度升高不超过40℃时的最大允许电流。此参数直接决定电感的带载能力,可避免因电流过大导致磁芯饱和(电感量骤降),保障电路输出稳定。
DCR仅22mΩ,属于同类产品中的低阻水平。低DCR意味着:① 直流功耗低(P=I²R),减少电源损耗;② 发热小,降低周边元件温度,提升系统可靠性。
采用SMD贴片封装,具体尺寸为7.3mm(长)×6.6mm(宽)×5mm(高),属于紧凑尺寸设计。适配标准贴片工艺,可通过自动化设备快速贴装,同时节省PCB空间,适合高密度电路布局。
磁芯采用一体成型结构,相比传统线绕电感(磁芯分上下盖):① 磁屏蔽性更好,EMI电磁干扰更低,减少对周边敏感电路的影响;② 抗振动性能提升,可承受运输、使用中的机械振动,降低虚焊风险;③ 结构紧凑,磁路损失小,进一步提升电感效率。
产品符合RoHS无铅环保标准,适配各类无铅焊接工艺(回流焊、波峰焊),满足电子行业绿色制造要求。同时,电感的温度范围(-40℃~125℃)可覆盖多数应用场景的环境温度需求。
YSPI0750-4R7M的参数特性使其适配以下场景:
益嘉源(YJYCOIN)是国内专注电感研发与制造的企业,拥有多年功率电感生产经验。YSPI0750-4R7M经过严格可靠性测试:
产品批量一致性好,可满足客户量产需求,同时提供技术支持与样品测试服务,降低选型风险。
该产品平衡了“性能、体积、成本”三大维度,是中低端功率电路的实用选择。

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.
