PK0810-470MB 功率电感产品概述

一、产品基本属性

PK0810-470MB是顺翔诺(SXN)品牌推出的非屏蔽功率电感,采用径向引线插件封装,属于中小功率电路常用元件。产品型号中,“470”对应标称电感值47μH,“B”标识精度等级±20%,核心参数清晰可辨,便于电路设计快速选型。作为插件式电感,其安装方式灵活,适配手工焊接与批量插件生产,兼顾成本与实用性。

二、核心电性能参数详解

该电感的核心参数明确,可稳定支撑多数中小功率场景需求:

  • 电感值与精度:标称电感量47μH,精度±20%,实际工作范围为37.6μH~56.4μH。此精度无需精密加工,兼顾性能与成本,适合对电感量波动不敏感的常规电路(如电源滤波、小功率驱动)。
  • 额定直流电流:连续工作允许的最大直流电流为1.5A,此时电感磁芯未饱和、温升及电感量变化均在规格内,可稳定承载小功率电源、电机驱动的电流负载。
  • 直流电阻(DCR):绕组直流电阻为100mΩ(0.1Ω),直接影响功耗(公式:(P=I^2×R))。当工作电流为1.5A时,功耗仅0.225W,温升可控,无需额外散热设计,电路效率较高。

三、物理与封装特征

  1. 径向引线插件封装:两个引脚从电感主体两端径向引出,安装时可垂直插入PCB板(节省垂直空间)或水平焊接(适配薄型电路),焊接工艺简单,不易出现虚焊,兼容手工与自动化生产。
  2. 非屏蔽结构:无磁屏蔽外壳,相比屏蔽型电感成本更低,但会产生轻微电磁辐射。该设计适合对EMI(电磁干扰)要求不高的场景(如小家电、玩具),若需低辐射可搭配屏蔽罩灵活使用。
  3. 紧凑体积:符合行业通用PK0810封装尺寸(外径≈8mm、高度≈10mm),体积小巧,可在PCB板上密集布局,适配小型化产品设计(如便携充电器、小型智能家居设备)。

四、典型应用场景

PK0810-470MB的参数与封装特性,使其适配以下场景:

  1. 小功率DC-DC转换:如5V转3.3V、12V转5V的电源模块,47μH电感量适配10kHz~1MHz常见开关频率,1.5A电流满足低功率设备供电需求。
  2. 消费类电子终端:小家电(加湿器、智能台灯)、玩具、小型充电器等,对成本敏感且EMI要求低,非屏蔽结构足够支撑功能实现。
  3. 简易滤波电路:电源滤波(降低纹波电压)、信号滤波(抑制高频噪声),利用电感储能特性稳定电流,提升电路抗干扰能力。
  4. 小型电机驱动:小功率步进电机、直流风扇的驱动电路,辅助稳定电机工作电流,减少抖动与噪声。

五、选型优势总结

  1. 性价比突出:非屏蔽结构降低成本,DCR较低提升效率,精度±20%满足常规需求,无需为超精密场景支付额外费用。
  2. 安装便捷:径向插件封装适配多种PCB工艺,手工焊接易上手,批量生产时插件机兼容性好,降低生产难度。
  3. 参数适配广:1.5A电流、47μH电感量覆盖多数中小功率场景,从电源转换到滤波、驱动,应用范围广,减少选型复杂度。
  4. 品牌可靠:顺翔诺(SXN)作为国内成熟元器件品牌,产品一致性较好,供货稳定,可满足批量生产需求。

该产品平衡了性能、成本与实用性,是中小功率电路设计的高性价比选择。

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
