YPRH0704-100M 产品概述

一、产品简介

YPRH0704-100M 是益嘉源(YJYCOIN)推出的一款磁胶屏蔽功率电感,标称电感值 10 μH,公差 ±20%,额定电流 1.84 A,直流电阻(DCR)49 mΩ,封装为 SMD,尺寸 7.3×7.3×4.5 mm。该器件以低 DCR、屏蔽结构和紧凑尺寸为特点,适用于各类开关电源滤波与电流传输场景,是中小功率电源管理系统的常用元件。

二、主要规格参数

  • 型号:YPRH0704-100M
  • 品牌:YJYCOIN(益嘉源)
  • 电感值:10 μH ±20%
  • 额定电流(Irated):1.84 A
  • 直流电阻(DCR):49 mΩ
  • 类型:磁胶屏蔽电感(屏蔽式功率电感)
  • 封装:SMD,尺寸 7.3 × 7.3 × 4.5 mm

三、结构与封装特点

磁胶屏蔽结构通过磁性材料和封装工艺减少磁通外泄,降低对周边电路的电磁干扰(EMI);表面贴装(SMD)设计便于自动化贴装与回流焊工艺,适合高密度 PCB 布局。封装体积在保证较大电流能力的同时,兼顾热量散逸和机械强度。

四、性能与应用价值

  • 低损耗:49 mΩ 的 DCR 在同级别功率电感中属较低水平,减少 I^2R 损耗,换算在额定电流下的铜损约为 0.166 W(P ≈ I^2·R = 1.84^2 × 0.049)。
  • 屏蔽抑干扰:磁胶屏蔽结构有利于降低磁耦合和外部干扰,适合对 EMI 有一定要求的电源模块。
  • 空间与装配:7.3 mm 的边长与 4.5 mm 的高度适用于常见点对点电源走线和模块化设计。
  • 公差与稳态:±20% 公差适合电源滤波、去耦等对精确度要求不高但对可靠性与耐久性要求高的场合。

五、典型应用场景

  • DC–DC 降压/升压转换器(作为储能/滤波电感)
  • LED 驱动与背光电源
  • 车载电子(非高温极限)与消费类电源模块
  • 电源滤波器、输入/输出滤波以及电流平衡电路
  • 工控与通讯设备的电源管理单元

六、选型与使用建议

  • 电流余量:建议连续工作电流按额定电流的 70%–85% 进行选型,以考虑温升与磁饱和影响。
  • 温升与散热:在布局时注意周围散热条件,避免长期在高温环境下工作导致电感退磁或 DCR 上升。
  • 回流焊兼容:推荐采用行业通用的回流焊工艺(峰值温度通常不超过 260°C),并按 PCB 布局减少热应力集中。
  • 测试确认:在最终系统中验证电感在实际工作频率下的感值、直流电阻与纹波电流下的温升与饱和特性(厂家数据仅为标称条件)。

七、可靠性与检验

常规检验项目包括外观、尺寸、直流电阻、实际电感值及频率响应测试;必要时进行温升测试、寿命老化与热冲击测试。屏蔽式设计有助于抗干扰能力,但在强磁场或极端温度下仍需验证。

八、包装与采购信息

YPRH0704-100M 常见为卷带(Tape & Reel)SMD 包装,便于贴片机自动化生产。采购时建议向供应商确认最小起订量、供货批次一致性及相关认证资料。

九、总结

YPRH0704-100M 以 10 μH、1.84 A 的电流能力及较低的 DCR 为主要优势,适合中小功率电源滤波与能量传输场景。选型时需结合系统的电流余量、温升与 EMI 要求进行综合评估,必要时向益嘉源供应商索取更详细的频率特性、饱和曲线及可靠性数据以完成最终设计验证。

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
