FTC404030S470MBCA 产品概述
一、产品简介
FTC404030S470MBCA 为长江微电（cjiang）推出的一款小型一体成型贴片电感，型号中的“470”对应感值 47 μH。器件采用 T‑CORE 结构与扁线工艺，一体成型设计，体积小巧且结构稳定，适用于对体积与组装可靠性有较高要求的消费类与工业类电子产品。
二、主要参数
- 感值：47 μH
- 额定电流（Ir）：1.4 A（连续使用参考值）
- 饱和电流（Isat）：2.2 A（磁通密度引起感值显著下降时的电流）
- 直流电阻（DCR）：约 550 mΩ
- 类型：一体成型电感（T‑CORE，扁线）
- 封装：SMD，外形尺寸 4.1 × 4.1 mm
三、关键特性
- 小体积、高度集成：4.1×4.1 mm 的表面贴装封装，利于高密度 PCB 布局。
- 扁线与一体成型工艺：降低体积且提高机械强度，适合自动贴装与回流焊工艺。
- 较高的饱和电流：Isat 2.2 A 可在瞬态冲击或峰值负载时维持工作而不易饱和。
- 中等 DCR：550 mΩ 在保证阻抗的同时兼顾损耗与温升，适用于中低功率场合。
四、典型应用
- DC‑DC 降压/升压转换器的输入/输出滤波与能量储存；
- 电源入口处的共模/差模滤波与 EMI 抑制；
- 便携式设备、电池供电模块与 IoT 终端的电源管理；
- LED 驱动与小功率电机驱动电路中的滤波元件。
五、选型与使用建议
- 电流留有余量：长期工作电流建议按额定电流的 70%–80% 选配（即约 1.0–1.1 A）以降低温升并避免接近饱和区。遇有较长脉冲或瞬态峰值，应关注 Isat 指标。
- 考虑 DCR 带来的功耗：550 mΩ 在连续电流下会产生一定功耗（P=I^2·R），高电流场景需评估温升与散热。
- PCB 布局：建议在电感附近提供足够铜面做散热，并保证进出线短而粗，以减少串联寄生阻抗与 EMI。
- 焊接工艺：支持常规 SMD 回流焊；存储与回流温度按工厂推荐曲线执行以保证可靠性。
六、包装与测试建议
器件适合自动化贴装与批量放料。工程样机阶段建议做电感值随温度与电流的响应测试、热稳定性试验及长期老化验证，确保在目标应用环境下性能满足要求。

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.
