YSPI1050-100M — 10 μH 一体成型功率电感 产品概述

一、概述

YSPI1050-100M 是益嘉源(YJYCOIN)推出的一款表面贴装(SMD)一体成型功率电感,标称电感 10 μH,公差 ±20%,专为中高电流开关电源和电源滤波场景设计。器件体积紧凑(11.5 × 10 × 5 mm),直流电阻(DCR)极低(19.3 mΩ),额定电流 6 A、饱和电流(Isat)可达 11 A,适用于对能耗、温升和体积有严格要求的电源模块。

二、主要规格

  • 型号:YSPI1050-100M
  • 品牌:YJYCOIN(益嘉源)
  • 电感值:10 μH
  • 公差:±20%
  • 额定电流(Irms):6 A
  • 饱和电流(Isat):11 A(定义为电感下降到额定值一定比例时的电流)
  • 直流电阻(DCR):19.3 mΩ
  • 类型:一体成型功率电感(molded)
  • 封装/外形尺寸:SMD,11.5 × 10 × 5 mm

三、主要特性与优势

  • 低 DCR、低损耗:19.3 mΩ 的低直流电阻有助于降低 I^2R 损耗,提高转换效率,减小温升。
  • 高饱和电流:11 A 的 Isat 提供良好瞬态和峰值电流容忍度,适合开关电源的脉冲电流环境。
  • 一体成型结构:机械强度高、可靠性好,抗震动能力强,利于波峰/回流焊工艺的稳定性。
  • 紧凑尺寸:小体积便于在空间受限的移动设备、电源模块中布局。
  • 适用范围广:通用型功率电感,适配多种拓扑与应用场景。

四、典型应用场景

  • DC-DC 降压/升压转换器(buck/boost)
  • 电源管理模块(PMIC、VRM)
  • 汽车电子与工业电源(在满足工作温度范围的前提下)
  • LED 驱动电源、便携电源、电池管理系统(BMS)
  • 马达驱动与电源滤波器

五、选型与设计建议

  • 电流裕量:推荐将器件的额定电流与系统连续工作电流保持一定裕量,若电路存在较大电流脉冲,应以 Isat 判断峰值容忍度。
  • 温升与损耗计算:根据工作电流的有效值计算 P = I^2 × DCR,评估散热与温升;必要时在 PCB 上留足散热铜箔或采用散热通道。
  • 直流偏置效应:在较大直流偏置下电感值会下降,应参考厂方的电流-电感特性曲线或在目标电流条件下实测。
  • 布局建议:尽量缩短与功率开关器件之间的走线,减小回流环路面积,靠近输入/输出电容安放以降低 EMI。通过孔(vias)可用于多层板的热与电流分布。
  • 焊接工艺:兼容常见无铅回流焊流程,焊接后建议做外观与电气测试以确认焊接质量。

六、可靠性与测试

建议参考供应商提供的可靠性数据与测试报告,常见验证包括焊接性测试、温度循环、湿热老化、振动与冲击测试、直流耐流测试等。实际应用中可做批量取样的电感值、DCR 与绝缘/耐压测试。

七、储存与装配注意事项

  • 建议按供应商包装方式(干燥密封包装)储存,防潮处理以保证焊接性。
  • 贴片时避免强力挤压或侧向剪切力,防止机械损伤。
  • 在高温或高湿环境下作业时,应做好防护并尽快完成焊接流程。

八、订购信息与技术支持

  • 标准订购型号:YSPI1050-100M(如需更详细的特性曲线、工艺规范或样品测试数据,请联系 YJYCOIN(益嘉源)销售或技术支持获取完整数据手册和测试报告)。

YSPI1050-100M 以其低 DCR、高饱和电流和紧凑封装,适合需要高效率与高电流密度的电源设计,是 DC-DC 模块、电源滤波和工业/车用电源等场合的可靠选择。

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
