SL0650-220M 产品概述

一、产品简介

SL0650-220M 是台湾陆海出品的一体成型贴片合金电感,额定参数针对中大电流电源滤波与能量储存场景优化。器件为SMD封装,外形尺寸7.1×6.6 mm,结构紧凑、机械强度高,适用于自动贴装与回流焊工艺。

二、主要参数

  • 电感值:22 μH,公差 ±20%
  • 额定电流:3 A(连续工作)
  • 饱和电流(Isat):5 A(电感下降明显的临界值)
  • 直流电阻(DCR):98 mΩ
  • 封装:SMD,尺寸 7.1×6.6 mm
  • 类型:一体成型合金电感

三、产品特性

  • 高电流承载:额定3A,饱和5A,适合中功率DC-DC变换器与电源滤波器。
  • 低直流电阻:98 mΩ 在相应电流下可保持较低导通损耗,降低发热与转换损失。
  • 稳定性好:合金磁芯与成型工艺保证在温度与电流变化下电感特性稳定。
  • 机械可靠:一体成型适合自动化贴片与多次回流焊,抗振动性能优良。

四、典型应用

  • 开关稳压器(Buck/Boost)输入/输出滤波与能量储存
  • 电源管理模块、LED驱动电源、车载电子(非高温区)
  • 电池供电系统的纹波抑制与电流环路元件
  • EMI滤波与LC谐振网络

五、选型与注意事项

  • 根据实际电流选择:连续工作电流应不超过额定3A,若存在较大脉动或启动冲击,应按饱和电流与额外裕量选型。
  • 考虑DCR对效率影响:98 mΩ 会带来I^2R损耗,评估发热与散热条件,必要时增加散热或并联多只电感。
  • 电感公差 ±20%:在对精度要求高的谐振或时序电路中需预留容差。
  • 环境与温度:确认工作温度范围及磁芯温漂对电感值的影响,避免长期接近饱和区工作。

六、封装与焊接建议

  • 推荐采用标准回流焊曲线,避免超过制造商给定的峰值温度与时间。
  • 焊盘设计应参考厂方推荐尺寸,保证焊接可靠性与良好散热路径。
  • 对于多次回流或严苛振动环境,建议增加粘胶固定或采用合适的PCB固定结构。

七、质量与测试

  • 建议在设计验证阶段进行:L值随DC偏置测试、DCR测量、温升试验、振动与热循环测试以及焊接可靠性验证。
  • 量产时关注批次一致性与供应稳定性,向供应商索取可靠性与放行报告以确保长期可靠运行。

如需器件的PCB封装尺寸、回流焊曲线或样品测试数据,可进一步提供,我将协助给出更具体的落地建议。

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.

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
