YSMC0420V-100M 产品概述
一、产品简介
YSMC0420V-100M 是益嘉源（YJYCOIN）推出的一款面向开关电源和电源滤波的功率一体成型贴片电感。器件尺寸为4.0×4.0×2.0 mm，电感量 10 μH，公差 ±20%，适合体积受限但需较大电流承载能力的电源应用。
二、主要参数
- 电感值：10 μH ±20%
- 额定电流（Ir）：2.6 A（连续工作时的推荐电流）
- 饱和电流（Isat）：4.0 A（磁通下降显著的参考点）
- 直流电阻（DCR）：125 mΩ
- 封装尺寸：4.0 × 4.0 × 2.0 mm（SMD）
- 类型：一体成型功率电感（SMD）
三、关键特性
- 高频性能良好，适合降压/升压转换器与输入滤波应用。
- 一体成型结构强度高、抗震性能好，适合表面贴装工艺。
- 低 DCR 有利于降低铜损、提高效率，但需权衡电感值和损耗。
- 较高的饱和电流（4 A）允许短时冲击电流存在，但长期工作建议按额定电流选择以避免磁饱和和过热。
四、典型应用场景
- 同步/非同步降压转换器（buck）；
- 升压（boost）电源模块；
- 输入/输出 EMI 滤波器；
- 汽车电子、工业控制、电池供电设备等需紧凑封装与中等电流的场合。
五、封装与机械注意
器件为表面贴装封装，标注尺寸 4.0×4.0×2.0 mm。焊盘设计与布局应参考厂方推荐的焊盘图与锡膏模板，以保证焊接可靠性与热传导。器件体积小，贴装时需注意回流焊温度和加热速率，避免应力集中。
六、选型与使用建议
- 连续工作电流建议不超过额定电流 2.6 A，留有裕量以避免温升和电感降低；短时脉冲电流可以接近 Isat，但不建议持续。
- 注意直流偏置对电感值的影响：随着电流上升，实际电感会下降，设计时应结合数据手册或样品测量结果进行评估。
- 若电路对 DCR 或热量敏感，可选择更低 DCR 或更大封装型号。
七、焊接、储存与可靠性
建议遵循厂方回流焊曲线（一般电子元件回流峰值常见于 240–260 °C 范围），具体以制造商资料为准。储存时避免潮湿和强光直射，贴片前建议按 IPC/JEDEC 规范进行烘干处理（如有潮湿等级要求）。
八、测试与验收要点
- 测量电感值时应标明测试频率与振幅（L 随频率和 DC 偏置变化明显）。
- DCR 测量建议在 20 °C 下进行，温升会增加电阻。
- 进行温升试验以确认在额定电流下的温升是否在可接受范围内，必要时做长期老化与冲击试验。
九、采购与替代
型号：YSMC0420V-100M，品牌：YJYCOIN（益嘉源）。采购时请确认批次样品与数据手册一致，如需更高精度或更大电流能力，可考虑同系列其他规格或更大封装的功率电感。若需应用支持或更详细的电磁特性曲线，请向供应商索取完整数据手册与样品测试报告。

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.
