FTC322520S4R7MBCA 产品概述
一、产品简介
FTC322520S4R7MBCA 是长江微电（cjiang）推出的一款功率贴片电感，标称电感值 4.7 μH，公差 ±20%，适用于中高电流开关电源和电源滤波场合。器件为 SMD 封装，外形尺寸 2.5 × 3.2 mm，体积小、可并联或单独使用于空间受限的电源模块中。
二、主要特点
- 电感值：4.7 μH，适合用于中低 MHz 工作频率的电源滤波与储能。
- 额定电流：3.5 A（长期连续工作电流参考），饱和电流（Isat）4 A（超过此值电感量会显著下降）。
- 直流电阻（DCR）：81 mΩ，电流通过时产生的导通损耗可通过 I^2·R 估算。
- 封装：SMD，尺寸 2.5×3.2 mm，便于表面贴装自动化生产。
- 品牌：长江微电（cjiang），适配常见 SMT 贴片工艺和回流温度曲线。
三、典型应用
- DC-DC 降压（Buck）转换器储能电感
- 电源输入滤波与去耦，抑制共模/差模干扰
- LED 驱动器、电池供电设备、电动工具及便携式消费电子
- 工业电源模块与通信设备的电源管理
四、主要参数（便于快速查阅）
- 电感值：4.7 μH ±20%
- 额定电流：3.5 A
- 饱和电流（Isat）：4 A
- 直流电阻（DCR）：81 mΩ
- 封装：SMD，尺寸 2.5 × 3.2 mm
- 型号：FTC322520S4R7MBCA（长江微电）
五、选型与使用建议
- 电流裕量：设计时建议工作电流低于额定电流以降低温升，并尽量留有余量（例如不超过额定值的 80%），以避免接近饱和导致电感骤降。
- 损耗估算：根据 DCR 计算导通损耗 P = I^2·R，举例在 2 A 时损耗约 0.324 W（2^2×0.081），以评估温升与散热需求。
- 直流偏置影响：注意工作中的直流偏置会降低有效电感值，需在目标工作点验证实际电感。
- 并联使用：若单颗电感不能满足电流或感值要求，可并联多颗以减小等效 DCR 并提高载流能力，但需考虑 PCB 布局与电流均分。
六、封装与焊接注意
- 采用标准回流焊工艺，遵循元件厂商推荐的回流曲线和预热、峰值温度限制。
- PCB 设计时注意焊盘尺寸与散热铜箔面积，必要时增加过孔或热沉来改善散热。
- 在高振动或冲击环境建议做可靠性评估，确认焊点与贴装牢固。
总结：FTC322520S4R7MBCA 以其紧凑尺寸和较高的额定电流，适合用于各种中功率开关电源与滤波场景。选型时需关注直流电阻导致的损耗、直流偏置对电感值的影响以及实际工作电流下的热管理，才能在系统中获得稳定可靠的性能。

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.
