YPRH1207C-470M 功率电感产品概述

一、产品核心定位与应用方向

YPRH1207C-470M是益嘉源(YJYCOIN)推出的磁胶屏蔽贴片功率电感,针对中小功率直流转换、滤波场景优化设计,兼顾「体积紧凑性」「电流承载能力」与「抗电磁干扰(EMI)性能」,可覆盖消费电子、车载电子、工业控制等多领域的常规电源需求。

二、关键电气参数详解

2.1 电感量与精度

电感值为47μH±20%,属于功率电感的常用规格,20%精度满足大多数电源电路的「储能」「滤波」需求(如DC-DC buck电路的输出滤波、电源适配器的EMI滤波),无需额外高精度校准,可降低系统整体成本。

2.2 额定电流与损耗

  • 额定直流电流(Isat):3A:指电感在「工作温度上升≤20℃(典型值)」时的最大持续直流电流,若负载电流≤3A,电感不会出现磁饱和,性能稳定;若超过额定电流,电感量会快速下降,甚至损坏。
  • 直流电阻(DCR):200mΩ:低DCR设计可显著降低功率损耗(3A时损耗仅1.8W),减少发热,提升电源转换效率(如将DC-DC转换效率从85%提升至88%左右),同时延长产品使用寿命。

2.3 屏蔽特性

采用磁胶屏蔽结构,相比非屏蔽电感,可有效抑制电磁辐射(EMI),减少对周边敏感电路(如射频模块、传感器)的干扰,符合《GB 9254-2016》等EMC标准要求,适合对干扰敏感的车载、消费电子场景。

三、结构与封装优势

3.1 封装尺寸

封装为SMD-4P(12×12mm),贴片式四引脚设计,体积紧凑(长12mm×宽12mm),适合PCB空间有限的紧凑型产品(如笔记本电源、车载中控模块),自动化贴装效率高(与常规0805电阻贴装兼容)。

3.2 耐温与可靠性

磁胶电感通常支持**-40℃~125℃工作温度范围**(益嘉源该型号典型耐温),可适应高低温环境(如车载冬季-20℃、工业现场100℃);焊接时兼容常规回流焊工艺(峰值温度240-260℃,持续时间≤10秒),无虚焊、假焊风险。

四、典型应用场景

  1. 车载电子:汽车中控电源模块、LED氛围灯驱动、倒车影像供电电路(需抗干扰+耐温);
  2. 消费电子:笔记本电脑电源适配器、路由器DC-DC转换电路、智能音箱滤波模块;
  3. 工业控制:小型PLC电源滤波、传感器信号调理电路、小型电机驱动电源;
  4. LED照明:LED面板灯驱动电源、路灯恒流控制模块(需稳定储能)。

五、选型与使用注意事项

  1. 电流匹配:负载最大电流需≤3A(若环境温度高于85℃,建议降额20%使用);
  2. 精度需求:若电路需±10%以下精度(如高精度仪表电源),需更换高精度电感型号;
  3. PCB设计:焊盘尺寸需匹配引脚间距(典型引脚间距1.2mm),避免引脚受力变形;
  4. 存储条件:常温干燥环境(湿度≤60%)存储,避免受潮影响电感性能(受潮后需烘干后再使用)。

六、总结

YPRH1207C-470M凭借「低损耗、抗干扰、紧凑体积」的核心优势,成为中小功率电源电路的高性价比选择,覆盖多行业常规应用场景,满足大多数电源设计的「性能-成本」平衡需求。

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
