FHD3012S-2R2MT 产品概述
一、产品简介
FHD3012S-2R2MT 是长江微电（cjiang）推出的一款功率电感，封装为 SMD 3×3 mm，额定电感值为 2.2 µH（公差 ±20%）。该器件针对高密度开关电源与电源管理模块设计，兼顾小体积与大电流能力，适合现代移动与嵌入式电源方案对体积与效率的双重要求。
二、主要性能参数
- 电感值：2.2 µH ±20%
- 额定电流（Irms）：2.35 A（连续额定）
- 饱和电流（Isat）：3.35 A（定义为电感下降到指定比例时）
- 直流电阻（DCR）：约 90 mΩ
- 封装：SMD，3 × 3 mm
- 品牌：cjiang（长江微电）
三、主要特点
- 小尺寸、高密度：3×3 mm 尺寸便于在受限空间中布局多相电源或紧凑型 DC-DC 模块。
- 较高的电流承载能力：额定电流 2.35 A、饱和电流 3.35 A，能应对开关电源中的峰值电流冲击。
- 低直流电阻：约 90 mΩ，降低铜损，有利于提高转换效率并减小发热。
- 表面贴装工艺：适配自动化贴装与回流焊工艺，便于量产应用。
四、典型应用场景
- 降压（Buck）/ 升压（Boost）开关稳压器中的输出电感
- 电源管理模块（PMIC）、多相电源滤波器
- 消费类电子、通信设备、工业控制板的电源变换
- LED 驱动与便携设备电源方案
五、选型与使用建议
- 电流裕量：选用时应以实际工作电流（尤其是 RMS 与峰值）低于额定电流和饱和电流为准，建议保留 10–30% 余量以避免在突发工况下进入饱和。
- 频率与损耗：在高开关频率下需关注铁损与涡流损耗对效率的影响，必要时参考厂商频率特性曲线与温升数据。
- PCB 布局：电感两端走线尽量短、粗、对称，靠近功率器件布局以减少寄生电感与 EMI；如需散热，可在引脚下方增加过孔或铜箔。
- 回流焊与可靠性：遵守厂商推荐的回流温度曲线与湿度防护措施，避免超出器件耐温、机械应力造成性能退化。
- 验证测试：最终应用前建议在实际工作电流与温度条件下做电感值、DCR、温升及效率测试。
六、封装与采购提示
- 标识：型号为 FHD3012S-2R2MT，SMD 3×3 mm 封装。
- 包装方式：常见为卷带（Tape & Reel），便于贴片机上料；具体包装规格与起订量请以供应商报价单或技术资料为准。
- 建议获取：在大批量采购前索取样品并参考完整数据手册与可靠性报告，以确保指标满足目标应用需求。
七、注意事项
- 工作环境高温或强磁场可能影响电感性能与寿命，设计时需考虑环境退化。
- 避免与敏感模拟电路或磁性元件过近放置，以防磁耦合或干扰。
- 如对电感的频率特性、温升曲线或长期可靠性有严格要求，应向厂商索取详细测试资料或定制版本。
如需更详细的频率特性曲线、温升数据或封装尺寸图，请提供具体使用工况或联系长江微电索取 FHD3012S-2R2MT 的完整数据手册。

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.
