FTC252012S1R5MBCA 产品概述

一、产品简介

FTC252012S1R5MBCA 是长江微电(cjiang)推出的一款表贴功率电感,专为中小功率开关电源点位(Point-of-Load)设计。器件尺寸紧凑,封装为 SMD,外形标称 2.0 × 2.5 mm,适合高密度布局与自动贴装生产。凭借较高的饱和电流与合理的直流电阻,实现了在开关稳压器中对滤波与能量储存的可靠支持。

二、主要参数

  • 电感值:1.5 μH(公差 ±20%)
  • 额定电流:3.7 A(连续工作条件下保证温升与性能)
  • 饱和电流(Isat):4.5 A(在规定条件下电感明显下降前的极限)
  • 直流电阻(DCR):≈44 mΩ(典型值,低损耗有利于降低功耗)
  • 封装:SMD,尺寸 2.0 × 2.5 mm
  • 品牌:cjiang(长江微电)

三、核心性能特点

  • 高电流能力:4.5 A 的饱和电流与 3.7 A 的额定电流,使其能承受较大的峰值和连续电流,适合 1A‑4A 级别的 DC‑DC 降压模块。
  • 低直流电阻:约 44 mΩ 的 DCR 有助于减小 I^2R 损耗,提高转换效率并降低发热。
  • 小型化封装:2.0×2.5 mm 的体积利于高密度布板与多相电源设计。
  • 成本与可靠性平衡:±20% 的容差为通用电源方案提供了成本与性能的合理折衷。

四、典型应用场景

  • 移动设备与平板电脑的点位输出电源(PoL)
  • 嵌入式主板、通信设备的开关稳压器滤波元件
  • LED 驱动与消费类电子电源模块
  • 工业控制与 IoT 终端的 DC‑DC 电源设计(需根据环境与认证要求选择)

五、封装与安装建议

  • 建议采用推荐 PCB 焊盘尺寸与焊盘阻焊过孔布局,确保良好热散与可靠焊接;对贴片工艺使用标准回流焊曲线,避免过快升温或长时间高温。
  • 在布局时尽量缩短与开关管、整流器的走线长度,以减少寄生电感与 EMI;必要时与屏蔽或地铜结合改善散热与抗干扰性能。

六、选型与注意事项

  • 额定电流(3.7 A)为连续工作条件下的参考值,若实际电路存在明显纹波电流或较高环境温度,应选择更高额定值或留裕量。
  • 饱和电流(4.5 A)表示磁芯在接近饱和时的极限,设计时应确保峰值电流不长期接近此值以避免电感值突降。
  • ±20% 的电感公差适合一般电源滤波应用,但对精密时间常数或谐振电路要求较高时,应考虑低公差型号或配合调试。
  • 若用于汽车或高可靠性场景,请向供应商确认相应的认证与温度等级。

七、品质与采购建议

  • 采购时建议索取并核对完整的数据手册和样品进行实测(包含 L‑vs‑I、DCR、温升与耐焊性测试)。
  • 与供应商确认批次一致性与可靠性测试(如高温老化、热冲击等),并在量产前完成电源板级验证。

FTC252012S1R5MBCA 以其小尺寸、高电流能力和低 DCR 的特性,适合用于各类中等功率点位电源设计,是追求体积与效率平衡应用的常用选择。如需更详细的电气特性曲线、温升数据或推荐 PCB 封装图,请联系长江微电或获取正式数据手册。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
