FTC252012S2R2MBCA 产品概述
一、产品简介
FTC252012S2R2MBCA（长江微电 cjiang）是一款表面贴装功率电感，标称电感值 2.2 μH，公差 ±20%。器件封装为 SMD，外形尺寸为 2.0 × 2.5 mm，专为高频开关电源与功率滤波场景设计，兼顾体积、热耗与磁通饱和性能。
二、主要电气参数
- 电感值：2.2 μH ±20%
- 额定电流（Irms）：3.0 A（长期允许通过的连续电流）
- 饱和电流（Isat）：3.8 A（电感下降到规定偏差前的最大直流偏置电流）
- 直流电阻（DCR）：约 55 mΩ（影响功率损耗与温升）
这些参数决定了器件在 DC-DC 降压、LED 驱动及输入输出滤波中的适用性。
三、性能特点与优势
- 小型封装（2×2.5 mm），便于高密度 PCB 布局与移动设备使用。
- 较高的额定电流和较高的饱和电流裕量，适合中小功率转换器。
- 适中 DCR 在兼顾损耗和热性能方面平衡良好，有助于降低开关损耗与温升。
四、典型应用场景
- 同步降压/升压转换器（SBC、PMIC 模块）
- 输入/输出滤波网络，抑制开关噪声与纹波
- 移动终端、通信设备与工业控制的电源管理模块
- LED 驱动与电机驱动的低功率级滤波
五、使用建议与注意事项
- 选型时应以实际工作电流（含纹波）低于额定电流并留有裕度，避免接近饱和电流工作点。
- DCR 会带来 I^2R 损耗，需评估温升并在布局中留出散热条件。
- 焊接采用标准回流工艺，建议参考厂方推荐焊盘尺寸与回流曲线以保证可靠性。
- 在高频应用中，注意与开关管、二极管的走线最小化回路面积，减小 EMI。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
