FTC201610S4R7MBCA 产品概述
一、产品概况
FTC201610S4R7MBCA 为长江微电（cjiang）推出的一款功率贴片电感，封装尺寸 1.6 × 2.0 mm，设计用于紧凑型电源管理和开关稳压器场合。标称电感值 4.7 μH（公差 ±20%），兼顾体积与电流承载能力，适合移动设备、物联网模组、可穿戴和小型电源模块中的输入滤波与储能应用。
二、关键电气参数
- 电感值：4.7 μH ±20%
- 额定电流（Irated）：1.6 A（持续工作建议）
- 饱和电流（Isat）：2.0 A（磁芯开始显著降感处）
- 直流电阻（DCR）：约 190 mΩ
- 封装：SMD，尺寸 1.6 × 2.0 mm 这些参数决定了在不同工作频率和电流条件下的效率、温升与滤波性能。
三、典型应用场景
- 降压（Buck）开关电源的电感元件
- 电源输入侧滤波、去耦与储能
- 移动终端、蓝牙/无线模组、电源管理芯片周边
- 工业与消费类低功率电源模块
四、设计与布局建议
- 电流裕量：建议在选择时留有余量，长期工作以额定电流 1.6 A 为基准，避免长期接近饱和电流 2.0 A。
- PCB 布局：电感两端应与开关管、电容形成最短回流路径，输入/输出电容靠近器件引脚放置以降低 EMI。
- 热管理：高 DCR（190 mΩ）在大电流时会产生明显功耗，注意器件附近散热与走铜宽度。
- 焊接工艺：兼容标准回流焊；避免过度机械应力，遵循厂商推荐的焊盘和回流曲线。
五、选型与注意事项
- 若追求更低损耗或更高效率，可优先考虑 DCR 更低或额定电流更高的型号。
- ±20% 的电感公差在滤波频率计算时需考虑，影响谐振频率与滤波性能。
- 对于峰值较高或脉冲负载，需确认电感在脉冲条件下的电流应力与温升。
- 试样评估：在目标应用中进行直流偏置与温升测试，验证实际感值降低与效率影响。
FTC201610S4R7MBCA 以小型化封装和良好电流能力为特点，适合空间受限且需中等电流承载的电源设计。根据应用场景合理预留电流与热裕度，可发挥稳定可靠的电源滤波与储能功能。若需详细封装尺寸、回流曲线或可靠性数据，可联系供应商获取完整数据手册。

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.
