MHCI05018-2R2M-R8A 产品概述
一、产品简介
MHCI05018-2R2M-R8A 是奇力新（chilisin）推出的一款表面贴装功率电感，额定电流 5A，标称电感值 2.2 µH（容差 ±20%），饱和电流（Isat）为 6.5A。器件采用磁胶屏蔽结构，尺寸紧凑（5.7 × 5.4 mm），适合高密度电源模块与点位负载（POL）应用。
二、主要电气参数
- 电感值：2.2 µH，容差 ±20%（典型量产范围约 1.76–2.64 µH）
- 额定电流（Irated）：5 A（连续载流能力）
- 饱和电流（Isat）：6.5 A（超过此值电感量将显著下降）
- 直流电阻（DCR）：约 35 mΩ（代表功耗表现）
- 封装形式：SMD，外形约 5.7 × 5.4 mm
- 类型：磁胶屏蔽功率电感（低漏磁、抗振动）
三、主要特性与优势
- 高电流承载：5A 额定电流适合中等功率点的降压转换器与电源输入滤波。
- 良好饱和余量：6.5A 的饱和电流保证短时冲击或峰值电流下电感仍能维持性能。
- 低直流电阻：35 mΩ 提供较低的 I^2R 损耗，但在高电流应用下仍需注意功耗和温升。
- 磁胶屏蔽：降低磁通外泄与相邻元件的干扰，改善 EMI 表现并增强机械稳固性。
- 尺寸紧凑：5.7×5.4mm SMD 封装利于高密度布局与自动化贴装，适配现代紧凑型电源板。
四、典型应用场景
- DC-DC 降压转换器（同步/非同步）中的能量储存电感
- 模块化电源与点位负载（POL）稳压器
- 电源输入滤波器、输出滤波及电流平滑场合
- 消费电子、通信设备、工控电源等要求中等电流密度与体积受限的场合
五、PCB 布局与使用建议
- 尽量缩短电感与开关晶体管/电容之间的走线，降低寄生电感与环路面积以减少 EMI。
- 输出侧配合低 ESR 输出电容，确保环路稳定性与瞬态响应。
- 对连续 5A 工作点，建议留足散热余量并考虑一定的电流降额（70–90% 视环境与散热条件），以控制温升与延长寿命。
- 采用符合厂商回流焊工艺的焊盘设计，避免过大机械应力。
六、可靠性与品质控制
奇力新作为知名磁性元件厂商，产品在材料选择、绕制和封装工艺上具备成熟控制。建议在设计前索取详细数据手册与温升、频率响应曲线、饱和特性曲线与耐焊性规范，以进行电路仿真与热设计验证。
七、选型与订购信息
型号：MHCI05018-2R2M-R8A；品牌：chilisin（奇力新）；封装：SMD；主要参数请以厂商数据手册为准。在选型时关注实际工作频率、峰值电流与允许温升，必要时通过样片评估在目标电路中的电感变化、效率和温度表现。
如需我帮您整理数据手册关键曲线（L vs I、温升测试、频率特性）或给出 PCB 参考封装和焊盘建议图，请告知您的工作频率与环境条件。

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.
