CD54YP0504-4R7M 功率电感产品概述

一、产品核心定位与基础属性

CD54YP0504-4R7M是益嘉源(YJYCOIN) 推出的一款非屏蔽贴片式功率电感,专为中小功率电子电路的储能、滤波及EMI抑制需求设计。作为紧凑型功率电感,其兼顾了尺寸小型化与电气性能的平衡,适用于消费电子、电源模块、物联网设备等对空间要求严格的场景,是替代同类进口型号的高性价比选择。

二、关键规格参数详解

该电感的核心参数直接决定了应用边界,关键指标及实际意义如下:

  • 电感值与精度:标称4.7μH,精度±20%——此精度范围满足大多数功率电路的工程需求(无需过度追求高精度带来的成本提升),可覆盖100kHz~1MHz的常见开关频率;
  • 额定直流电流:2.8A——指电感在正常工作时允许通过的最大直流电流(无明显磁饱和或温升超标),可支撑中等功率的DC-DC转换、LED驱动等电路;
  • 直流电阻(DCR):60mΩ——低直流电阻是核心优势之一,在2.8A电流下的铜损仅约0.47W(I²R=2.8²×0.06),显著降低电路热应力;
  • 封装与尺寸:SMD贴片封装,外形尺寸5.8mm×5.2mm×4.5mm(长×宽×高)——紧凑尺寸适配自动化贴装,节省PCB布局空间,适合便携式设备的高密度设计;
  • 类型:非屏蔽电感——相比屏蔽电感成本更低、结构更简单,适用于对电磁干扰(EMI)要求不高的场景,或搭配外部屏蔽罩使用。

三、电气性能与应用优势

  1. 低损耗高效能:60mΩ的DCR可减少铜损,提升电源电路效率(如DC-DC降压电路效率可提升2%~3%),同时降低设备温升,延长电池续航(针对便携设备);
  2. 宽温稳定可靠:采用高导磁率磁芯与优质漆包线,在-40℃~+125℃的宽温度范围内性能稳定,满足工业级与消费级设备的环境要求;
  3. 贴装兼容性强:符合IPC标准的SMD封装,可通过回流焊、波峰焊等常规工艺加工,无需特殊设备,降低生产制造成本;
  4. 抗振动能力:磁芯与线圈采用紧密绕制工艺,可承受常规运输与使用中的振动冲击,避免开路或参数漂移。

四、典型应用场景

该电感的参数与尺寸特性,使其在以下场景中表现突出:

  1. 消费电子便携设备:智能手机、平板电脑、智能手表的电源管理模块(DC-DC降压电路),利用小尺寸适配设备内部紧凑空间;
  2. 小型开关电源/适配器:5V/1A、12V/0.5A等小功率电源适配器的滤波电感,满足低损耗与小体积需求;
  3. LED驱动电路:低压LED灯带、小型LED显示屏的恒流驱动模块,支撑中等功率电流输出(如12V/0.2A~0.5A的LED串);
  4. 物联网(IoT)设备:智能传感器、低功耗网关的电源单元,兼顾效率与空间,适配电池供电的低功耗需求;
  5. 车载辅助电路:车载充电器的辅助滤波、小型车载显示屏的电源模块(需结合实际环境测试,参数基本满足低功率车载场景)。

五、品牌与品质保障

益嘉源(YJYCOIN)作为国内专注电感研发的厂商,其产品遵循ISO9001质量体系,CD54YP0504-4R7M符合RoHS环保标准(无铅、无镉等有害物质),且经过批量可靠性测试(冷热冲击、振动测试),可确保量产一致性与长期稳定性,为客户提供高性价比的替代方案。

该产品以“小尺寸、低损耗、高可靠性”为核心卖点,覆盖了中小功率电路的主流需求,是电子设计中平衡成本与性能的优选之一。

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
