PSPMAA1270H-221M-CBF 产品概述
一、产品简介
PSPMAA1270H-221M-CBF 为谱罗德（PROD）推出的一款一体成型功率电感，标称电感值 220 µH，精度 ±20%。该器件采用表面贴装（SMD）封装，整体尺寸为 12.8 x 13.2 x 6.5 mm，结构紧凑，适合空间受限的电源模块与滤波电路使用。
二、主要技术参数
- 型号：PSPMAA1270H-221M-CBF
- 电感值：220 µH ±20%
- 额定电流：3 A（Iz）
- 饱和电流（Isat）：5 A（定义为电感下降到额定值一定比例时）
- 直流电阻（DCR）：约 320 mΩ
- 封装形式：SMD，一体成型功率电感
- 尺寸：12.8 x 13.2 x 6.5 mm（长 x 宽 x 高）
- 品牌：PROD（谱罗德）
三、性能特点
- 高饱和电流：5 A 的饱和电流保证在瞬态或冲击负载下仍能维持磁性特性，适合降压转换器、大电流滤波场合。
- 合理的直流电阻：320 mΩ 在相应电流范围内兼顾损耗与磁性能，适用于中等功率等级。
- 一体成型结构：机械强度高，温度循环与振动可靠性好，便于自动贴装与回流焊接。
- 封装紧凑：适配背板、通信设备、电源模块及工业控制等需高可靠性与有限空间的应用。
四、典型应用
- DC-DC 降压/升压电源滤波与储能元件
- 通信与服务器电源模块
- LED 驱动与消费电子电源管理
- 工业控制与车载电子（视具体认证与环境测试结果而定）
五、设计与使用建议
- 请按照额定电流 3 A 进行长期电流设计，瞬态允许靠近 Isat 但应避免长期工作在饱和区，以防电感值显著下降。
- 布局时电感与开关管、二极管/电容距离要合理，输入输出走线尽量短且宽，减少寄生电感与噪声。
- 回流焊工艺建议遵循厂家焊接温度曲线，避免超过器件最大温度限值。
- 在高温环境或高频纹波场景下，应考虑电流与温升的额定余量（derating）。
六、可靠性与品质保障
谱罗德产品通过常规电气与环境可靠性测试（温升测试、振动与冲击、焊接热冲击及高低温循环等），并提供批次一致性控制。建议在关键应用中进行样机验证与长期寿命评估。
若需样品、详细曲线（电感随电流/温度的变化）、或封装库文件（PCB footprint / 3D）与应用参考，请联系供应商或谱罗德技术支持获取更详尽资料。

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.
