PSPMAA0803H-6R8M-ANP 产品概述

一、产品简介

PSPMAA0803H-6R8M-ANP 为谱罗德(PROD)推出的一款高电流功率电感,标称电感值 6.8 µH,公差 ±20%,封装为表面贴装(SMD),外形尺寸约 8.5 × 8 mm。该器件面向中高电流开关电源与电源滤波应用,设计以提供低直流电阻与较高饱和电流能力为主。

二、主要规格与电气参数

  • 电感值:6.8 µH ±20%
  • 额定电流(Irated):5.2 A(连续工作条件下建议不超出此值)
  • 饱和电流(Isat):9 A(接近或超过时电感值显著下降)
  • 直流电阻(DCR):53 mΩ(典型值)
  • 封装:SMD,尺寸约 8.5 × 8 mm
  • 品牌:PROD(谱罗德)

三、性能说明与热损耗计算示例

  • DCR 导致的铜损为 P_loss = I_rms^2 × DCR。按额定连续电流 5.2 A 估算:P_loss ≈ 5.2^2 × 0.053 ≈ 1.43 W;在饱和电流 9 A 时,损耗约为 4.29 W。由此可见在高电流或高纹波条件下器件温升不可忽视,设计时需留足散热余量。
  • 额定电流通常依据温升限值或规范条件给出;饱和电流表示电感值在高磁通时出现明显下降的边界,应避免长期运行在 Isat 附近以免影响电路性能。
  • DCR 标称值通常在 20 °C 下测量,实际应用中温度升高会使 DCR 增大,从而进一步增加损耗。

四、典型应用场景

  • 同步降压(Buck)/ 升压(Boost)开关电源中的储能电感或输出滤波器
  • 点-of-load 电源模块(POL),要求短封装但较高电流承载能力的场合
  • LED 驱动、DC-DC 模块输入滤波与电源噪声抑制

五、PCB 布局与使用建议

  • 将电感尽量靠近开关器件或输出电容放置,缩小高频回路面积以降低 EMI。
  • 使用较宽铜铜箔和足够过孔(vias)连接到电源层以增强散热;在热敏感应用中建议在器件下方和周围增加铜面积。
  • 考虑 ripple 电流的 RMS 值而非仅峰值,选择器件时以实际 RMS 电流为依据评估损耗与温升。
  • 设计时为器件留出检查与返修空间,避免与高热源元件紧密堆叠。

六、选型与可靠性注意事项

  • 若系统存在较大纹波电流或需连续工作在高负载,建议选择更低 DCR 或更高 Irated 的器件以降低温升与功耗。
  • 对电感的实际电感值、DCR 与温升最好在目标电路环境下验证;若对电感下降敏感,应保证工作电流远低于 Isat。
  • 存储与焊接按生产厂家的推荐规范执行,回流焊温度曲线应与器件耐受能力匹配。

总结:PSPMAA0803H-6R8M-ANP 以 6.8 µH、较高饱和电流(9A)与中等 DCR(53 mΩ)为特征,适合对电流能力有较高要求且空间有限的中功率电源应用。在选型与布局时需重点考虑铜损、温升与电感饱和特性,以确保长期可靠运行。若需更详细的尺寸图、频率响应或测试条件,请联系供应商获取完整数据手册。

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
