PK0810-331MB 功率电感产品概述

一、产品定位与核心属性

PK0810-331MB是顺翔诺(SXN)品牌推出的非屏蔽径向插件功率电感,属于中低功率场景的基础型电感元件。型号命名中,“PK”代表功率电感系列,“0810”为封装尺寸标识(常规直径8mm×高度10mm),“331”对应电感值330μH(33×10¹),“MB”后缀指向基础型非屏蔽规格。该产品核心面向成本敏感、安装便捷性要求高的电子设备,适配小电流电源滤波、信号耦合等场景,无需依赖SMT贴装设备即可快速应用。

二、关键技术参数深度解析

1. 电感值与精度

标称电感值330μH,精度±20%。该精度范围可覆盖多数民用电子设备的电源滤波需求(如5V/0.5A级电源的纹波抑制),同时兼顾生产工艺稳定性——无需额外校准即可满足批量应用,避免因参数波动导致电路调试成本增加。

2. 额定直流电流

500mA(DC)。此参数表示电感在持续承载500mA直流电流时,电感值变化不超过±20%精度范围,且无明显磁饱和现象。实测显示,电流≤450mA时电感值波动小于5%,可稳定支撑小功率电源模块的持续工作。

3. 直流电阻(DCR)

470mΩ。DCR是电感绕组铜损的核心指标,470mΩ的阻值在同类插件电感中属于合理区间:500mA电流下损耗约0.1175W,可有效降低电池供电设备(如智能手环、蓝牙耳机)的待机功耗,延长续航时间。

4. 结构与封装

  • 非屏蔽设计:无金属屏蔽罩,降低成本与体积,但需注意在高频通信等电磁干扰敏感场景需配合屏蔽措施;
  • 径向引线插件:引脚从电感两端径向伸出,支持垂直插装于PCB,手工焊接或波峰焊均可快速组装,尤其适合小批量生产或维修场景。

三、典型应用场景

该电感主要适配小电流、低干扰要求的电子设备,核心场景包括:

  1. 消费电子电源:如5V/1A以下手机充电器、蓝牙耳机充电盒、智能手环的DC-DC转换滤波模块;
  2. 物联网终端:低功耗温湿度传感器、智能门锁节点的电源稳压滤波,避免信号干扰;
  3. 小型家电控制板:加湿器、香薰机、小型LED台灯的电源模块,满足12V以下直流供电需求;
  4. DIY电子制作:如简易LED驱动电路、小型音频耦合电路的电感环节,安装便捷性突出。

四、性能优势与适配价值

  1. 成本控制优势:非屏蔽结构+插件封装,相比屏蔽电感成本降低约25%,适合量产项目的成本管控;
  2. 安装便捷性:无需SMT贴装设备,手工焊接或波峰焊即可快速组装,尤其适合中小电子厂或维修场景;
  3. 功耗与体积平衡:470mΩ低DCR减少铜损,PK0810小体积(直径8mm×高度10mm)节省PCB空间,适配紧凑设备设计;
  4. 环境稳定性:工作温度范围覆盖-40℃~85℃,可满足常规室内外环境使用,长期工作无明显磁性能衰减。

五、品质与合规说明

顺翔诺(SXN)作为国内成熟电感厂商,该产品符合RoHS 2.0环保标准(无铅无镉);磁芯采用铁氧体材料,一致性控制良好(电感值波动≤±2%);直流电阻一致性≤±5%,批量应用时参数波动小,降低电路调试难度。

该产品通过了常规环境可靠性测试(高低温循环、湿度老化),可满足多数民用电子设备的基础电感需求,是小功率场景下成本与性能平衡的优选方案。

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
