YSMC0430H-R33MB是益嘉源(YJYCOIN)针对中功率高密度电源场景推出的一体成型电感,核心目标是在4.1×4.1mm紧凑封装内,平衡“大电流承载、低损耗、抗干扰、高可靠性”四大需求,解决传统绕线电感在车载、服务器等场景下的“发热高、漏磁大、抗振动差”痛点。
电感值330nH,精度±20%——既避免了过高精度带来的成本冗余,又能满足主流DC-DC电源(如12V转5V/3.3V)的滤波、储能需求,保证输出纹波控制在50mV以内(符合多数电子设备的电源规范)。
DCR仅4.5mΩ,是同尺寸电感的低损耗水平——15A持续电流时,铜损仅为15²×0.0045=1.0125W,无需额外散热片即可满足多数场景需求,显著提升电源转换效率(可达92%以上)。
采用4.1×4.1mm表面贴装封装,引脚间距符合IPC标准,可直接兼容主流贴装设备,适配高密度PCB布局(如服务器主板、车载ECU),节省系统空间。
区别于绕线电感的“线圈+磁芯”结构,该电感通过高压模压将线圈与磁粉芯融合,优势显著:
YSMC0430H-R33MB通过“小尺寸+大电流+低损耗+高可靠性”的平衡设计,成为服务器、车载、工业等领域中功率电源的高性价比选择——既降低系统布局难度,又提升电源效率与稳定性,同时减少EMI干扰带来的调试成本,适合对空间、性能、可靠性有综合要求的场景。

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.
