PK0810-330MB 功率电感产品概述

一、产品基本定位

PK0810-330MB是顺翔诺(SXN)推出的一款插件式非屏蔽功率电感,属于中小功率电感范畴,核心定位为“成本可控+性能稳定”,适配对电磁干扰(EMI)要求适中、需快速原型开发或中小批量生产的电路场景。该产品无需复杂贴片设备,兼容手工焊接与波峰焊,是消费电子、小型家电、工业小模块等领域的通用型电感选择。

二、核心电性能参数详解

1. 电感值与精度

标称电感值为33μH,精度±20%,属于功率电感的通用规格。这一精度在工业级、消费级电路中无需额外校准,可满足DC-DC转换、电源滤波的纹波抑制需求,同时避免高精度电感带来的成本增加。

2. 额定电流与温升控制

额定电流为1.9A,指在-40℃~+85℃工作温度范围内,电感可长期稳定承载的电流值,此时绕组温升控制在40K以内(符合行业标准)。该电流覆盖1-2A功率区间,适配多数中小功率应用。

3. 直流电阻(DCR)

绕组直流电阻为75mΩ,属于同参数电感的低阻水平。低DCR直接降低电流损耗(损耗公式:P=I²×R),以1.9A额定电流计算,损耗仅约0.27W,可有效减少发热,提升电路能效,尤其适合移动电子设备(如移动电源)的续航优化。

4. 非屏蔽特性

采用非屏蔽绕线结构,相比屏蔽电感减少了磁屏蔽层成本,同时保留稳定电感性能。适合EMI要求不苛刻的场景(如家电内部),若需EMI抑制,可通过电路布局或外部屏蔽件辅助实现,兼顾成本与性能平衡。

三、结构与封装特性

1. 绕组与磁芯设计

绕组采用符合电流承载能力的漆包线紧密绕制,磁芯选用常规铁氧体材料(适配功率电感的储能与滤波需求),结构紧凑且电感值稳定性好,长期使用无明显漂移。

2. 径向引线插件封装

封装形式为径向引线插件,引脚间距符合常规PCB规范,安装无需特殊设备,手工焊接、波峰焊均可兼容,尤其适合中小批量生产或原型开发阶段,降低生产门槛。

四、典型应用场景

PK0810-330MB的参数与结构特点,使其在以下场景表现突出:

  1. 消费电子电源:小型手机充电器、移动电源的DC-DC降压电路,满足1-2A输出需求,低DCR减少发热;
  2. 小型家电控制板:电风扇、加湿器、智能台灯的稳压电路,非屏蔽结构降低成本;
  3. 工业控制小模块:传感器节点、小型PLC辅助电源,33μH电感配合滤波电容实现稳定供电;
  4. LED驱动电路:小功率LED灯串(柜台灯、应急灯)的恒流驱动,电感储能配合电路稳定输出。

五、市场竞争优势

  1. 成本与性能平衡:非屏蔽结构降低30%材料成本,同时低DCR与合理电流满足中小功率需求,性价比高于同参数屏蔽电感;
  2. 安装兼容性强:径向插件适配多种焊接工艺,无需特殊设备,适合从原型到批量的全流程生产;
  3. 可靠性稳定:顺翔诺(SXN)的绕线工艺与磁芯选型保证电感值稳定,长期工作无明显损耗;
  4. 通用规格覆盖:33μH为行业常用值,适配多数成熟电路设计,无需定制,缩短开发周期。

这款电感凭借“通用参数+成本优势+安装灵活”的特点,成为中小功率电路设计的优选元件,可满足不同行业的多样化需求。

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
