FTC252012SR10MBCA 产品概述
一、主要参数
FTC252012SR10MBCA（长江微电 cjiang）是一款面向高电流开关电源与功率滤波场景的贴片功率电感，主要参数如下：
- 标称电感值：100 nH ±20%
- 额定电流：12 A（连续工作）
- 饱和电流（Isat）：13.5 A（典型，达到此电流时电感量显著下降）
- 直流电阻（DCR）：约 6 mΩ
- 封装：SMD，尺寸 2.0 × 2.5 mm
二、产品特性
- 低 DCR、低损耗：6 mΩ 的直流电阻使器件在高电流下相对减少导通损耗，有利于提升转换效率。
- 高电流承载：12 A 连续额定、13.5 A 饱和保证在点负载与同步降压应用中的可靠性。
- 小型化封装：2×2.5 mm 封装适合高密度 PCB 设计与模块化电源布局。
- 稳定性：对温度与纹波电流具有良好抗饱和性能，适用于快开关频率的电源拓扑。
三、典型应用
- 同步降压（Buck）转换器输出滤波与储能
- 点对点（POL）电源模块与基板级电源
- 电源管理（PMIC）外围磁性元件
- EMI 滤波与大电流去耦场景
四、设计与使用建议
- 电流余量：建议连续工作电流留有余量（例如按额定电流的 80% 选型）以降低温升并延长寿命。
- 损耗估算：按 P = I^2·DCR 估算导通损耗，例如在 12 A 时约为 0.864 W，需评估 PCB 散热与周边布局。
- 饱和注意：应避免长期接近或超过 Isat（13.5 A），以防感值骤降影响环路稳定。
- 布局建议：尽量缩短电感与功率器件之间的回流环路，使用足够过孔改善散热，外圈留出铜箔散热区。
- 焊接兼容：SMD 工艺兼容无铅回流焊，建议参照 PCB 制造商与焊膏供应商的标准回流曲线。
五、封装与可靠性信息
- 小尺寸、表面贴装，便于自动化生产与高密度装配。
- 建议在样片阶段验证温升、纹波电流以及在目标工作温度下的感值变化，以确认满足系统要求。
- 长江微电（cjiang）型号适合对成本与体积有严苛要求但仍需较高电流处理能力的电源设计。
如需获取样片、详细尺寸图或电感随电流/温度的典型曲线，可联系供应商或索取产品规格书以进行更精确的热与电性能评估。

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.
