YSPI0630A-150M 产品概述

一、产品简介

YSPI0630A-150M 是 YJYCOIN(益嘉源)推出的一体成型功率电感,标称电感值 15 μH,公差 ±20%,额定电流 3A,饱和电流(Isat)5A。器件采用表面贴装(SMD)封装,尺寸 7.1 × 6.6 × 3.0 mm,直流电阻(DCR)约 98 mΩ,适用于各类开关电源与功率滤波场合,强调耐过载、结构稳固与易于自动化贴装。

二、主要电气参数

  • 电感量:15 μH(±20%)
  • 额定电流:3 A(连续工作时建议不超过此值以控制发热与温升)
  • 饱和电流(Isat):5 A(超过该电流时电感量将显著下降)
  • 直流电阻(DCR):98 mΩ(典型值)
  • 封装:SMD,7.1 × 6.6 × 3.0 mm
  • 型号:YSPI0630A-150M

注:±20% 的公差在设计滤波或储能电路时需预留裕量。

三、性能与特点

  • 一体成型结构,机械强度高,适合自动贴装与波峰/回流焊工艺。
  • 较高的饱和电流(5A)保证短时冲击电流下电感量稳定,适合降压转换器的脉冲负载。
  • 直流电阻 98 mΩ 在中等电流范围内提供良好效率与成本平衡,但在高电流下会产生显著铜损(例如在额定 3A 时 P_loss ≈ 0.882 W;在 5A 峰值时 P_loss ≈ 2.45 W),需注意散热。
  • 封装体积小巧,有利于高密度布局,但热量集中需合理散热设计。

四、典型应用场景

  • DC-DC 降压/升压转换器的储能电感。
  • 功率滤波(输入/输出滤波)与噪声抑制。
  • LED 驱动与便携电源管理。
  • 工业与通信设备的电源模块(在满足温升和效率要求下)。

五、选型与使用建议

  • 若系统常态电流接近或超过 3A,应选用更低 DCR 或更大截面的电感以降低功耗与温升。
  • 设计时考虑电感公差 ±20%,对滤波截止频率或能量计算留有裕度。
  • 对于有较大瞬态电流的应用,确保 Isat(5A)高于冲击峰值,否则电感量会下降影响稳定性。
  • 损耗估算:P = I^2 × DCR,用以评估热设计与散热需求。长期在高损耗工作点会影响寿命与可靠性,建议在评估后适当降额使用。

六、封装与焊接注意事项

  • 适用于标准回流焊工艺,推荐遵循制造商给定的回流温度曲线与焊接建议。
  • PCB 布局建议采用较宽的焊盘与厚铜走线,减小寄生电阻与热阻,必要时在焊盘下方或周围使用过孔与铜柱增强散热。
  • 贴装时避免强烈机械冲击,使用适配的取放头以防损伤器件外壳。

七、可靠性与储存

  • 储存应避免潮湿、高温与强腐蚀性气体环境,长期存放建议在干燥柜内保存并遵循制造商的保质期规定。
  • 使用时注意温升控制,长期高温会加速材料老化,影响电感稳定性与寿命。

总结:YSPI0630A-150M 是一款针对中等功率应用设计的一体成型 SMD 功率电感,体积小、饱和电流较高,适用于多种开关电源场景。设计时应关注 DCR 带来的损耗与热管理,合理评估电流裕度与电感公差,以保证系统的稳定与可靠。若需更详细的电感频率特性、温升数据或回流曲线,建议联系厂商获取完整数据手册与测试报告。

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
