SPM2510-220MA 产品概述
一、概述
SPM2510-220MA 为长江微电(cjiang)出品的小型功率电感，封装为SMD，尺寸仅2.0×2.5mm，标称电感值22µH，公差±20%。该器件面向体积受限且需中等电流承载能力的电源滤波与储能场合，兼顾尺寸与磁性能，为小型化电源设计提供电感元件选择。
二、主要参数
- 电感值：22 µH ±20%
- 额定电流（Ir）：850 mA（持续允许工作电流）
- 饱和电流（Isat）：1.1 A（电感下降到规定值时的电流极限）
- 直流电阻（DCR）：约1.1 Ω
- 封装：SMD，尺寸2.0 × 2.5 mm
- 品牌：cjiang（长江微电）
三、特性与优势
- 小尺寸：2×2.5mm 封装适合高密度PCB布局与移动终端、可穿戴设备等空间受限场合。
- 低体积设计：在保持22µH量级电感值的同时，节省PCB面积。
- 合理的电流承载：850mA 额定电流适合中小功率降压模块或滤波器应用。
- 明确的饱和电流指标：1.1A 饱和电流允许短时峰值通过，便于设计安全裕量。
四、典型应用
- 模拟与数字电源输入侧滤波（PI/LC滤波）
- 低功耗DC-DC降压模块和升压模块（中低输出电流）
- 电源噪声抑制与EMI滤波器
- 可穿戴、IoT节点、传感器供电滤波
五、设计与布局建议
- 为保持额定电流下的电感值，尽量把直流工作电流控制在850mA以下，避免长期接近或超过额定值导致温升及电感下降。
- DCR 为1.1Ω，电阻较高，设计时需关注功耗（I^2·R）与发热，在热敏元件附近留有热管理空间。
- 布局上尽量短连接线，与电源/开关器件的回流路径保持最短，减少寄生电阻与电感。
- 若应用在开关电源中，建议在靠近IC处布局，输入电容与电感紧密耦合以减小环路面积。
- 推荐常规回流焊工艺，遵循厂商的回流曲线（若无明确资料，按无铅回流规范处理）。
六、注意事项与选型提示
- 由于DCR偏高，不适合用于高电流、低压差的高效率电源主电感，更多用于滤波或中低功率场合。
- 设计时应综合考虑温升与功耗，必要时选用DCR更低或更大尺寸的电感以降低损耗。
- 关注实际工作频率下的磁芯损耗与电感随直流偏置的变化，必要时在样品测试条件下确认性能。
七、采购与质量
SPM2510-220MA 属于长江微电系列产品，适用于需要小型封装和中等电流的电源滤波场景。具体订购信息、最小起订量、可靠性测试报告及回流曲线建议联系厂商或授权分销商获取详细资料，以便在量产前完成样件验证与可靠性评估。

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.
