FTC252012SR22MBCA 产品概述
一、产品简介
FTC252012SR22MBCA 是长江微电（cjiang）推出的一款功率型表面贴装电感，额定电感值为 220nH（±20%），面向高频开关电源与大电流滤波应用。器件尺寸仅为 2.0 × 2.5 mm（SMD），适合对空间和封装密度有严格要求的电源模块与便携设备。
二、主要电气参数
- 电感值：220 nH（±20%）
- 额定电流（Irms）：8.2 A
- 饱和电流（Isat）：9.6 A（电感降至初始值的指定比例时测得）
- 直流电阻（DCR）：约 9 mΩ 这些参数表明该器件在数安培级别的连续电流下仍能保持较低功耗与良好滤波性能，适合高效率开关稳压器使用。
三、产品特点
- 小尺寸高电流：2×2.5 mm 封装实现高电流承载，便于在密集 PCB 布局中节省空间。
- 低 DCR：约 9 mΩ 的低直流电阻有利于降低导通损耗，提高转换效率。
- 高 Isat：9.6 A 的饱和电流保证在短时冲击或突发负载下电感仍能维持较稳定的电感量。
- 标准化 SMD 形式：便于自动化贴装与回流焊工艺。
四、典型应用场景
- 同步降压（Buck）/ 升压（Boost）开关电源电感
- 多相电源 / VRM 输出滤波
- 电源管理模块（PMIC）与功率模块
- PoE、USB PD 等高电流供电系统
- 工业电源与通信设备的电流滤波
五、使用与选型建议
- 连续电流选型时建议以额定电流 8.2 A 为基准，并考虑一定余量（例如选型时目标工作电流不超过 Irms 的 80%），以避免长期高温导致性能衰减。
- 对于存在较大瞬态电流的应用，应关注 Isat（9.6 A），并保证峰值不超过该值以免电感发生显著饱和。
- 在低频或要求严格的电流纹波抑制场景，应验证在工作频率与电流下的实际电感值与损耗。
六、PCB 与热管理提示
- 尽量把电感放置在电流路径上短且宽的走线位置，减少寄生电阻与电感，降低发热。
- 采用大散铜垫或多层连通的地平面/电源平面以帮助散热。
- 留意贴装方向与焊点质量，避免因焊接缺陷导致接触电阻增大。
七、可靠性与测试建议
- 建议在样机阶段进行温升测试与长期老化试验，评估在最大额定工作电流下的温度上升与电感稳态变化。
- 建议对焊接工艺（回流温度曲线）进行工艺验证，避免超温或长时高温影响磁芯材料性能。
八、封装与采购信息
- 封装：SMD，2.0 × 2.5 mm
- 品牌：cjiang（长江微电） 在采购时请确认完整型号（FTC252012SR22MBCA）、电气特性与批次文件，必要时索取样品与规格书以便在实际电路中验证性能。
如需示波器下的电流纹波、频率响应或在特定拓扑（例如同步降压）中的典型测试数据，我可以根据您的工作频率与电流条件给出更具体的建议与仿真指导。

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.
