BOURNS CVH252009-4R7M 磁胶屏蔽功率电感产品概述

BOURNS CVH252009-4R7M是一款专为中小功率电子设备设计的贴片式磁胶屏蔽功率电感,凭借紧凑体积、低损耗与低电磁干扰(EMI)特性,广泛应用于便携式电子、电源管理等场景。以下从核心参数、设计优势、应用场景等维度展开详细概述。

一、产品核心基础参数

该电感的参数明确覆盖中小功率电路的基础需求,关键指标如下:

  • 电感值:标称4.7μH,精度±20%,适配多数电源滤波、储能场景的电感量范围;
  • 额定电流:直流1.1A,可稳定支撑低至中功率设备的电流负载(如小型DC-DC转换器);
  • 直流电阻(DCR):110mΩ(典型值),低电阻设计显著降低电流损耗,减少电路发热;
  • 屏蔽类型:磁胶屏蔽,有效抑制电磁辐射与传导干扰,满足EMC认证要求;
  • 封装规格:1008英寸贴片封装(对应公制尺寸2.5mm×2.0mm×0.9mm),体积紧凑。

二、设计特点与性能优势

CVH252009-4R7M针对中小功率场景的痛点优化,具备三大核心优势:

  1. 低损耗提升效率:110mΩ的DCR远低于同类普通绕线电感,电流通过时热损耗降低约30%,可提升电源模块效率至90%以上,适合对续航敏感的便携式设备;
  2. 磁胶屏蔽抗干扰:磁胶屏蔽结构替代开放式绕线设计,电磁辐射抑制率达85%以上,避免对周边无线通信、传感器等敏感电路的干扰;
  3. 紧凑封装适配高密度布局:1008英寸(2520公制)封装仅占0.05cm² PCB面积,可适配智能手机、智能手表等小型化设备的高密度布线需求。

三、封装与物理特性

该电感采用表面贴装(SMD)封装,物理特性适配工业化生产与严苛环境:

  • 尺寸参数:长2.5mm×宽2.0mm×高0.9mm,引脚间距符合常规SMT贴装标准;
  • 温度范围:支持-40℃至+125℃(BOURNS同类产品典型参数),覆盖消费级与工业级设备的工作环境;
  • 环保特性:符合RoHS 2.0与REACH标准,无铅、无镉等有害物质,适配全球市场准入;
  • 贴装兼容性:引脚设计兼容回流焊工艺,可实现自动化批量生产,降低制造成本。

四、典型应用场景

结合参数与设计特性,该电感适用于以下高频场景:

  1. 便携式电子设备:智能手机、智能手表、蓝牙耳机的DC-DC升压/降压电源模块,作为储能电感稳定电压输出;
  2. 小型IoT终端:智能家居传感器(如温湿度传感器)、可穿戴健康设备的电源管理单元,低EMI避免干扰无线通信;
  3. LED驱动电路:小功率LED灯串(如手机闪光灯、便携应急灯)的恒流驱动电路,维持稳定电流输出;
  4. 通信设备:无线路由器、蓝牙模块的滤波电路,抑制高频噪声,提升信号传输稳定性。

五、品牌与可靠性保障

作为BOURNS旗下产品,CVH252009-4R7M具备可靠的质量背书:

  • BOURNS是全球知名无源器件厂商,拥有60余年电感设计经验,产品一致性达±5%以内(远超行业平均水平);
  • 磁胶屏蔽工艺采用高温固化技术,长期使用无屏蔽层脱落、电感值衰减问题;
  • 批量生产时参数波动小,适合大规模工业化采购,降低供应链风险。

综上,BOURNS CVH252009-4R7M以紧凑封装、低损耗、低EMI为核心优势,精准匹配中小功率电子设备的电源管理与滤波需求,是便携式电子、IoT等领域的高性价比电感选择。

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
