ETQP3M6R8KVP 产品概述
一、主要特性
ETQP3M6R8KVP 是松下（PANASONIC）一款车规级一体成型功率电感，标称电感值 6.8 µH（±20%），额定电流 2.9 A，饱和电流 Isat 6.1 A，直流电阻 DCR 65.7 mΩ，表面贴装封装尺寸为 5.5 × 5 mm，满足 AEC‑Q200 车规可靠性要求，适合中等电流点位负载应用。
二、电气参数解读
- 电感值 ±20%：适用于对电感公差要求不严的降压拓扑或噪声滤波器，设计时应考虑初始公差对谐振和输出纹波的影响。
- 额定电流 2.9 A：表示在规定温升下的连续电流能力。
- 饱和电流 6.1 A：当电流靠近或超过此值时，电感量显著下降，开关电源的纹波、电流峰值和稳定性会受影响。
- DCR 65.7 mΩ：影响铜损与效率。按近似直流计算，若恒流为 2.9 A，则 I^2·R ≈0.55 W（仅为估算，实际应以 RMS 电流和工作温度为准）。
三、封装与机械
SMD 5.5×5 mm 的一体成型结构便于高速贴装与自动化生产，机械强度好、磁屏蔽性较高。请在使用前确认器件高度与 PCB 布局、过孔及周边器件间距匹配，参照厂家推荐的焊盘尺寸和回流工艺规范。
四、典型应用场景
- 汽车电子点位电源（车规等级保证长期可靠性）
- 车载信息娱乐与仪表盘的 DC‑DC 降压转换器
- 工业与消费类中等电流的开关电源、LED 驱动与电源滤波
五、设计与使用建议
- 留有饱和裕度：建议将工作峰值电流远离 Isat（可按数据表的 L(I) 曲线和温升曲线确定安全裕度，如保持峰值 ≤ Isat 的 ~80% 并使平均电流低于额定值）。
- 考虑 DCR 对效率与温升的影响，必要时在热敏区域加入散热或改变封装布局。
- 高频性能、磁损与核心损耗随频率、温度和磁通变化，设计前应参考厂家频率响应和损耗数据。
- PCB 布局：尽量缩短电感进出线圈的回路，增大铜箔宽度，必要时使用热铜和过孔以改善散热。
六、可靠性与资料
该型号通过 AEC‑Q200 车规认证，适用于严苛环境。选型和最终验证请以松下官方规格书（datasheet）为准，包含 L‑I 曲线、温升曲线、焊接工艺及推荐封装尺寸图。

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.
