SRP7028A-6R8M 产品概述
一、产品简介
SRP7028A-6R8M 是 BOURNS 出品的一款屏蔽式贴片功率电感，标称电感值 6.8 µH，公差 ±20%。针对车用与工业电源应用设计，具备较高的额定电流与饱和电流能力，适合用于电源滤波与能量储存场合。器件通过 AEC‑Q200 车规认证，可靠性满足汽车电子严苛要求。
二、主要电气参数
- 电感值：6.8 µH（±20%）
- 额定电流（Irated）：4.5 A
- 饱和电流（Isat）：8 A（定义为电感下降一定比例时）
- 直流电阻（DCR）：54 mΩ（典型）
- 屏蔽结构，降低辐射与耦合干扰
三、结构与封装
该器件为表面贴装（SMD）封装，外形尺寸约 6.6 × 7.3 mm，紧凑、适合高密度板级布局。屏蔽金属外壳与磁芯结构有助于控制磁通外泄，减小周围敏感电路的干扰影响。
四、主要特性与优势
- 高电流能力：额定 4.5 A 连续工作，8 A 饱和裕量，满足大电流开关电源需求。
- 低损耗：较低 DCR 降低功率损耗与发热，有利于效率优化与热管理。
- 屏蔽设计：抑制磁场外泄，改善 EMI 性能，便于靠近敏感器件布局。
- 车规品质：通过 AEC‑Q200 认证，适用于汽车电子环境下的温度循环与振动应力。
五、典型应用场景
- 汽车车载电源模块（DC‑DC 降压／升压转换）
- 汽车信息娱乐与辅助系统电源滤波
- 工业与通信电源的输入输出滤波器
- 电源管理模块（PMIC）与点‑到‑点供电网络
六、选型与使用建议
- 电流裕量：在实际设计中对额定电流进行适当裕量（例如 20–30%），以避免长期热应力引发性能衰减。
- 温升与散热：关注器件在最大工作电流下的温升，必要时优化散热或选择更低 DCR 的型号。
- 饱和裕量：若工作于有大电流瞬态或电感需承受脉冲电流，应以 Isat 为准并留有安全裕度。
- 布局注意：尽量将电感与开关器件、整流器按最佳流向布置，减小环路面积；屏蔽有利于靠近敏感线路放置。
- 焊接与存储：遵循厂商推荐的回流温度曲线，避免机械应力；长期存储需防潮防尘。
七、可靠性与质量保证
SRP7028A‑6R8M 基于 BOURNS 的车规级制造工艺并符合 AEC‑Q200 标准，经过温度循环、湿热、振动和机械冲击等验证，适合车载与高可靠性场合使用。具体可靠性测试数据与回流曲线建议参照厂商数据手册以获得完整信息。
如需样品、电气特性曲线或在特定拓扑下的仿真数据，可进一步提供工作条件与电路参数以便给出更精确的应用建议。

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.
