YSMC201210H-100MB是YJYCOIN(益嘉源) 推出的贴片功率电感,采用行业标准0805封装(公制尺寸:长2.0±0.2mm、宽1.2±0.2mm、高1.0±0.2mm),属于小型化一体成型电感范畴。型号编码含义清晰:
该电感的关键参数直接决定应用场景,具体解析如下:
电感标称值为10μH,实际值范围在8μH~12μH之间(±20%精度)。此精度适配大多数电源转换、滤波电路,无需极端精准控制的场景,兼顾成本与性能平衡。
直流电阻为600mΩ(0.6Ω),是线圈固有电阻。根据功率公式P=I²R,1A工作时功耗约0.6W,需结合工作温度(常规-40℃~125℃)评估散热,避免过热影响可靠性。
相比传统绕线电感,该产品因一体成型结构具备显著优势:
模压工艺将线圈封装在磁性材料中,大幅减少漏磁,降低对周边电路的电磁干扰(EMI),适合对电磁兼容(EMC)要求高的设备(如通信、车载电子)。
无裸露线圈,抗振动、抗冲击能力提升(可满足车载级振动测试),适合工业控制、车载等恶劣环境。
相同电感值下,体积比绕线电感缩小约30%,0805封装适配智能手机、智能穿戴等小型设备的PCB设计。
模压工艺实现参数稳定控制,批量产品的电感值、DCR波动极小,便于电路调试与大规模生产。
结合参数与优势,该电感主要适用于以下场景:
智能手机、平板电脑、笔记本电脑的DC-DC降压/升压电路(如CPU、内存供电),满足小型化、低EMI需求。
蓝牙耳机、智能手环、无线耳机的电源模块(含无线充电电路),适配0805封装的紧凑空间。
小型工业控制器、传感器模块的辅助电源,抗振动特性适合现场环境。
车载胎压监测(TPMS)、USB充电模块等,满足机械稳定性与温度要求。
为确保电路可靠性,需注意以下几点:
该概述覆盖产品核心属性、参数、优势及应用,可作为选型与设计参考。

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.
