YSMC201210H-100MB 一体成型电感产品概述

一、产品基本属性

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:

  • “201210”对应封装尺寸(2012为长×宽,10为高度);
  • “100M”表示电感标称值为10μH,精度等级为**±20%**(行业“M”为20%精度标准代码)。

二、核心电气参数详解

该电感的关键参数直接决定应用场景,具体解析如下:

1. 电感值与精度

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。

2. 电流特性

  • 额定电流(Irms):1A:指连续工作时,电感值变化≤10%(行业常规)的最大允许电流,此时发热可控、性能稳定。
  • 饱和电流(Isat):1A:指电感值下降30%的临界电流。需注意:该电感额定电流与饱和电流一致,即工作电流≤1A时电感值稳定;超过1A则电感值快速下降,可能导致电路性能波动(如DC-DC效率降低)。

3. 直流电阻(DCR)

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。

三、一体成型电感的技术优势

相比传统绕线电感,该产品因一体成型结构具备显著优势:

1. 电磁屏蔽性优异

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)。

2. 机械稳定性强

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。

3. 小型化与高密度

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。

4. 批量一致性好

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。

四、典型应用场景

结合参数与优势,该电感主要适用于以下场景:

1. 消费电子电源管理

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。

2. 智能穿戴与通信

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。

3. 工业控制与传感器

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。

4. 低功耗车载电子

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。

五、选型与使用注意事项

为确保电路可靠性,需注意以下几点:

  1. 电流匹配:工作电流≤1A,避免超过饱和电流导致性能下降;
  2. 散热设计:1A工作时功耗0.6W,需保证PCB焊盘散热良好,避免密闭高温环境;
  3. 封装适配:0805封装需匹配焊盘尺寸(常规1.6mm×1.0mm),确保焊接可靠;
  4. 精度需求:若需更高精度(如振荡电路),需选择±10%/±5%型号。

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。

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
