YDPK0912-122K工字功率电感产品概述

YDPK0912-122K是YJYCOIN(益嘉源) 推出的一款插件式工字功率电感,针对中低功率电路的储能、滤波及噪声抑制需求设计,凭借紧凑尺寸、稳定参数及高性价比,广泛适配消费电子、工业控制等场景。

一、产品基本定位

该电感属于工字功率电感范畴,区别于普通色环电感,其工字磁芯结构可实现更大电感量与更高饱和电流,适合功率传输场景;采用插件封装,安装方式灵活,支持手工焊接与自动化插件生产线;品牌端依托益嘉源的电感研发制造经验,产品参数一致性好,可满足批量应用的稳定性要求。

二、核心电气参数详解

1. 电感值与精度

电感标称值为1.2mH(型号中“122K”代表12×10²μH=1200μH=1.2mH),精度±10%。该精度范围可覆盖大多数常规电路需求(如电源滤波、信号滤波),无需额外校准即可实现稳定功能,同时降低了生产端的筛选成本。

2. 饱和电流(Isat)

饱和电流为300mA,定义为电感电流达到该值时,电感值下降至初始值的30%(行业常规标准)。此参数直接决定了电感的最大负载能力:当电路工作电流不超过300mA时,电感值保持稳定,可有效避免因磁饱和导致的滤波效果下降、纹波增大等问题。

3. 直流电阻(DCR)

绕组直流电阻为2.3Ω,反映了电感的直流损耗特性。低DCR意味着在相同工作电流下,电感自身发热更少,能量转换效率更高,尤其适合对功耗敏感的场景(如小型便携设备),可降低电路整体温升。

4. 工作频率范围

常规工作频率覆盖20kHz~200kHz(工字电感典型范围),适配开关电源、LED驱动等低频功率电路,对高频噪声的抑制效果显著。

三、物理特性与封装设计

1. 封装尺寸与结构

封装规格为D11×L15mm(直径11mm,长度15mm),尺寸紧凑,可节省PCB布局空间,适合小型化产品设计;工字磁芯结构采用高导磁率锰锌铁氧体材料,绕线均匀缠绕于磁芯柱,相比环形电感,工字结构更易批量生产,且电感值一致性更好。

2. 引脚与焊接性能

采用插件式引脚,引脚材质为镀锡铜,抗氧化能力强,焊接时润湿性能好,可避免虚焊问题;引脚强度高,在振动环境下不易脱落,适合工业级或消费电子的常规应用场景。

四、典型应用场景

该电感凭借参数适配性,可覆盖多领域应用:

  1. 消费电子:小型手机充电器、蓝牙耳机充电盒的电源滤波电路(减少输出纹波);LED台灯驱动电路的限流与储能。
  2. 工业控制:低功率PLC的信号滤波模块(抑制电磁干扰EMI);小型温度传感器的供电稳压电路。
  3. 小家电:加湿器、桌面风扇的控制电路(实现电流稳定);智能门锁的低功耗电源管理。
  4. 通讯设备:433MHz低频无线模块的滤波电感(减少信号噪声)。

五、品牌与品质保障

YJYCOIN(益嘉源)作为国内电感制造厂商,YDPK0912-122K经过多道品质管控:

  • 生产端:每批次电感需经过电感值测试、DCR测试、饱和电流测试,参数偏差严格控制在规格范围内;
  • 环境适应性:工作温度范围为**-40℃~+85℃**,满足不同地域(如北方低温、南方高温)的应用需求;
  • 供货稳定性:支持小批量样品与大批量订单,交期稳定,适合研发与量产阶段。

综上,YDPK0912-122K工字功率电感以平衡的参数设计、紧凑尺寸及高性价比,成为中低功率电路的理想选择,可满足多场景的储能、滤波及EMI抑制需求。

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
