YDPK0912-102K 产品概述

一、产品简介

YDPK0912-102K 是 YJYCOIN(益嘉源)推出的一款工字形插件功率电感,标称电感值 1.0 mH,公差 ±10%,适用于需要较大感值且电流不高的直流/低频滤波与抑噪场合。封装为通孔插件,外形尺寸约 D11 × L15 mm,结构稳固、便于手工或波峰/回流后焊接安装。

二、主要性能参数

  • 型号:YDPK0912-102K
  • 品牌:YJYCOIN(益嘉源)
  • 电感值:1.0 mH ±10%
  • 饱和电流(Isat):1 A(超过此电流时电感量显著下降)
  • 直流电阻(DCR):约 2 Ω
  • 封装:插件(通孔),尺寸 D11×L15 mm
  • 类型:工字电感(Ferrite/磁芯绕线结构)

三、产品特性与优势

  • 大感值:1 mH 的感值便于实现低频滤波与延时、抑制直流偏移等功能。
  • 结构可靠:工字形磁芯和均匀绕线,机械强度好,适合通孔固定,耐振动。
  • 易于安装:插件封装适配传统通孔电路板,维修和样板调试方便。
  • 适用于低电流工况:Isat=1 A,适合小功率模块、传感与信号级滤波应用。

四、典型应用场景

  • 开关电源的输入/输出滤波(低电流场合);
  • 模拟和音频电路的低频滤波与直流隔离;
  • EMI/射频噪声抑制,作为共模/差模滤波网络的一部分(低电流侧);
  • 传感器、仪表、计量等对电磁干扰敏感的电路隔离与滤波。

五、设计与使用建议

  • 电流与功耗评估:DCR≈2 Ω,在额定电流 1 A 时的直流功耗为 P = I^2·R = 2 W,造成明显发热与电压降(≈2 V)。建议在连续工作时对电流做降额处理,常用做法为将连续电流限制在 60%–80% 范围(例如 0.6–0.8 A),以控制温升与损耗。
  • 饱和与工作点:在接近或超过 Isat(1 A)时,电感量会显著下降,滤波与储能能力受影响。设计时留有裕量,避免在峰值或持续工作中触及饱和区。
  • 热管理:高 DCR 导致功耗集中,布局时注意周围器件的热敏性和散热路径,必要时在 PCB 上留出散热铜箔或采取通风散热措施。
  • 布局与焊接:插件封装便于牢固焊接,建议沿电流走向最短化布线、避免与敏感信号线平行走线以减小耦合干扰。焊接时控制回流或波峰温度曲线,遵循厂商焊接指南以防磁芯或涂层损伤。
  • 测试与选型:在样机阶段通过实际电流、频率与温升测试验证滤波效果与寿命,必要时选用低 DCR 的替代件以提升效率,或采用并联/串联不同电感策略优化性能。

六、机械与采购信息

  • 外形与封装:插件式工字电感,外径/长度约 D11×L15 mm,便于通孔安装与手板验证。
  • 型号标识:YDPK0912-102K,购买时请确认型号、感值与 DCR 等关键参数。
  • 品牌:YJYCOIN(益嘉源),适用于中低电流功率滤波与噪声抑制项目。

七、选型提示

若目标电路对效率和压降敏感(如高电流 DC-DC 电源),建议优先选择 DCR 较低且 Isat 较高的功率电感;若侧重低频滤波、噪声抑制且电流需求较小,则 YDPK0912-102K 是结构紧凑、安装便捷的合适选择。在最终定型前,请结合实际工作电流、频率及热环境完成样机验证。

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
