YSPI0750-4R7M 一体成型功率电感产品概述

一、产品定位与核心价值

YSPI0750-4R7M是益嘉源(YJYCOIN)推出的SMD贴片一体成型功率电感,专为中大功率DC-DC转换、滤波及储能场景设计。产品以“小体积承载大电流、低损耗提升效率”为核心,适配消费电子、通信、工业控制等多领域的功率电路需求,是替代传统线绕电感的高性价比方案。

二、关键参数深度解析

1. 电感值与精度

电感标称值为4.7μH,精度±20%,满足多数功率电路对电感量的基本要求(如降压/升压转换器的储能电感)。该精度范围在量产中一致性良好,无需额外筛选即可稳定匹配电路设计。

2. 额定电流与饱和特性

额定电流为6.5A(直流电流,DC),指电感在25℃环境温度下,温度升高不超过40℃时的最大允许电流。此参数直接决定电感的带载能力,可避免因电流过大导致磁芯饱和(电感量骤降),保障电路输出稳定。

3. 直流电阻(DCR)

DCR仅22mΩ,属于同类产品中的低阻水平。低DCR意味着:① 直流功耗低(P=I²R),减少电源损耗;② 发热小,降低周边元件温度,提升系统可靠性。

4. 封装尺寸

采用SMD贴片封装,具体尺寸为7.3mm(长)×6.6mm(宽)×5mm(高),属于紧凑尺寸设计。适配标准贴片工艺,可通过自动化设备快速贴装,同时节省PCB空间,适合高密度电路布局。

三、工艺与可靠性优势

1. 一体成型工艺

磁芯采用一体成型结构,相比传统线绕电感(磁芯分上下盖):① 磁屏蔽性更好,EMI电磁干扰更低,减少对周边敏感电路的影响;② 抗振动性能提升,可承受运输、使用中的机械振动,降低虚焊风险;③ 结构紧凑,磁路损失小,进一步提升电感效率。

2. 环保与兼容性

产品符合RoHS无铅环保标准,适配各类无铅焊接工艺(回流焊、波峰焊),满足电子行业绿色制造要求。同时,电感的温度范围(-40℃~125℃)可覆盖多数应用场景的环境温度需求。

四、典型应用场景

YSPI0750-4R7M的参数特性使其适配以下场景:

  1. 消费电子:笔记本电脑、平板电脑、便携式充电器的DC-DC降压模块(如12V转5V/3.3V);
  2. 通信设备:路由器、交换机、基站的电源滤波及储能电感,满足多端口供电的电流需求;
  3. 工业控制:小型变频器、伺服驱动器的辅助电源电路,或PLC(可编程逻辑控制器)的低功耗模块;
  4. LED驱动:大功率LED照明(如工矿灯、路灯)的恒流驱动电路,实现高效储能与滤波;
  5. 车载入门场景:车载充电器、车载显示屏的电源模块(适配非严苛车规的通用场景)。

五、品牌与品质保障

益嘉源(YJYCOIN)是国内专注电感研发与制造的企业,拥有多年功率电感生产经验。YSPI0750-4R7M经过严格可靠性测试:

  • 温度循环测试(-40℃~125℃,1000次循环);
  • 振动测试(10~2000Hz,加速度2g);
  • 焊接可靠性测试(回流焊后无开裂、虚焊)。

产品批量一致性好,可满足客户量产需求,同时提供技术支持与样品测试服务,降低选型风险。

该产品平衡了“性能、体积、成本”三大维度,是中低端功率电路的实用选择。

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
