SRP7028A-5R6M 产品概述
一、产品简介
SRP7028A-5R6M 是 BOURNS 推出的车规级功率电感，额定电感值 5.6 µH（公差 ±20%），设计用于表面贴装（SMD）应用，封装尺寸为 6.6 × 7.3 mm。该器件提供较高的额定电流与饱和电流（额定电流 5 A，饱和电流 Isat 9 A），并通过 AEC‑Q200 车规认证，适合汽车与工业级电源系统中对可靠性要求较高的场景。
二、关键参数
- 电感值：5.6 µH ±20%
- 额定电流（Irms）：5 A
- 饱和电流（Isat）：9 A
- 直流电阻（DCR）：43 mΩ
- 封装形式：SMD，尺寸 6.6 × 7.3 mm
- 车规等级：AEC‑Q200
三、性能特点
- 高电流能力：5 A 连续电流与 9 A 饱和点，适合中大功率轨的能量储存与滤波。
- 相对低 DCR：43 mΩ 在保证效率的同时便于热管理与系统布局评估。
- 车规可靠性：符合 AEC‑Q200，可靠性与温度循环性能适合汽车环境。
- 紧凑封装：6.6×7.3 mm SMD 外形，便于高密度 PCB 布局与自动化贴装。
四、典型应用场景
- 汽车电子 DC‑DC 降压/升压转换器（车载电源管理）
- 工业电源模块与模块化电源（POL）
- 电机驱动与点火电源滤波器
- LED 驱动、电池供电系统及能量存储回路
五、设计与使用建议
- 电流与热勘测：在 5 A 工作点下，近似损耗为 P = I^2·DCR ≈ 1.08 W，系统设计时应评估器件温升及散热路径，必要时在 PCB 下方或周围增加铜箔以降低结温。
- 饱和裕量：避免长期工作在接近 Isat 的区间，建议在实际设计中留出裕量（视应用可采用 70–85% 的额定电流作为持续工作值）。
- PCB 布局：尽量缩短进出电感的电流回路、使用较宽的铜迹并考虑热沉区域；对于高脉冲电流，布置旁路电容靠近电感输入端以减小寄生。
- 焊接与可靠性：作为 SMD 器件，建议采用合适的回流焊工艺并参考厂商的焊接建议，避免长期超温或机械应力集中。
六、可靠性与替代方案
- 车规认证（AEC‑Q200）保证了在汽车工作温度与振动冲击下的稳定性，适合需长期稳定运行的电源设计。
- 若需更低 DCR 或更高额定电流，可在 BOURNS 系列中查找同尺寸或更大尺寸的功率电感作为替代；选择时需关注电感、DCR、Isat 与封装兼容性。
如需更详细的电气特性曲线（频率响应、饱和特性曲线、温度系数）或封装图纸与回流焊工艺建议，可提供后为您检索并给出工程级数据与布局参考。

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.
