YSMC0420V-1R0M 产品概述
一、产品简介
YSMC0420V-1R0M 为 YJYCOIN（益嘉源）推出的一体成型功率电感，标称电感值为 1.0 µH，公差 ±20%。器件为表面贴装封装（SMD），外形尺寸 4.0 × 4.0 × 2.0 mm，专为高电流、受限空间的电源滤波与能量储存场合设计。凭借低直流电阻与较高的饱和电流，本型号适合在高开关频率与大电流密度的电源管理系统中使用。
二、主要特性
- 电感值：1.0 µH，公差 ±20%
- 额定电流（Ir）：11 A
- 饱和电流（Isat）：11 A（在规定磁芯偏移下）
- 直流电阻（DCR）：约 8.9 mΩ，损耗小、效率高
- 封装尺寸：4.0 × 4.0 × 2.0 mm，一体成型结构，机械强度好
- SMD 贴片形式，适合自动化组装
三、典型应用
- 同步降压/升压 DC-DC 转换器
- 点对点（POL）电源、负载旁滤波
- 通信设备与基站电源模块
- 工业电源与储能管理
- 移动与便携设备的电源前端（需按温升与可靠性验证）
四、关键参数（便于快速查阅）
- 电感：1 µH ±20%
- 额定电流：11 A
- 饱和电流：11 A
- DCR：8.9 mΩ
- 封装：4.0×4.0×2.0 mm，一体成型 SMD
五、封装与布局建议
- 建议使用大面积的铜焊盘以降低接触电阻并增强散热；靠近电感的热源减小。
- 焊接时采用推荐的回流曲线，避免超温导致外壳或磁芯变化。
- 对于长时间大电流工作，需考虑电感温升与环境温度的差异，做适当降额使用。
- 布局时将电感与输出电容、功率开关紧密布局以降低环路面积，减少 EMI。
六、选型与可靠性提示
- 若系统工作电流接近或超过额定/饱和电流，应选择更高额定电流或更大饱和裕量的型号。
- DCR 与功耗直接相关，系统效率对热量敏感时优先考虑低 DCR 型号。
- 如需符合特定认证（如 RoHS、AEC-Q 系列等），请在采购前与供应商确认相关测试报告与版本。
YSMC0420V-1R0M 以其紧凑尺寸、高电流承载能力和较低损耗，适合对体积与性能有双重要求的电源设计场景。选型时结合实际工作频率、温度与效率目标进行验证，以获得最佳可靠性和性能表现。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
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.
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.
