YWLD2012-101K贴片电感产品概述

一、产品基本信息

YWLD2012-101K是YJYCOIN(益嘉源)推出的一款贴片功率电感,型号命名遵循行业通用规则:

  • “YWLD”为品牌电感系列专属前缀;
  • “2012”对应公制封装尺寸,适配英制0805封装;
  • “101”为电感值代码(10×10¹=100μH,若结合用户基础参数10μH,实际应为100K,此处按型号规范说明);
  • “K”表示电感值精度为±10%。

该产品专为低功耗电子设备设计,兼具小体积与稳定性能,适配表面贴装工艺(SMT)。

二、核心电气参数详解

产品核心参数直接决定应用场景,具体如下:

  1. 电感值与精度:标称电感值100μH(用户基础参数为10μH,对应100K),精度±10%,满足多数常规电路对电感偏差的要求;
  2. 额定电流:300mA(直流额定电流),指环境温度25℃下,电感温升不超过允许值(通常30-40℃)的最大连续工作电流,超出将导致性能下降;
  3. 直流电阻(DCR):1.17Ω,为绕组直流阻抗,低DCR可降低电路损耗、提升效率;
  4. 品质因数(Q值):[email protected],Q=2πfL/R,反映电感储能与损耗的比值,该数值表明2.5MHz下损耗小、储能效率高;
  5. 自谐振频率(SRF):25MHz,是电感寄生电容与自身谐振的频率,工作频率需远低于此值(建议≤5MHz),否则电感呈容性破坏电路特性。

三、封装与物理特性

  1. 封装尺寸:0805(英制)/2012(公制),尺寸约2.0mm×1.2mm×1.0mm,适配高密度PCB布局,满足便携设备小型化需求;
  2. 材料结构:铁氧体磁芯+铜漆包线绕组,铁氧体磁芯高磁导率、低损耗,绕组确保电感值稳定;
  3. 引脚类型:SMD贴片引脚,适配自动化贴装设备,实现批量高效生产;
  4. 温度范围:常规工业级-40℃~+85℃,覆盖多数消费电子、物联网终端的环境要求。

四、典型应用场景

结合参数特性,适用于以下低功耗场景:

  1. 消费电子:智能手机、智能手环、TWS耳机的电源滤波、信号耦合电路;
  2. 物联网终端:传感器节点、低功耗蓝牙(BLE)模块、WiFi模块的DC-DC转换电路;
  3. 小型通信设备:蓝牙/WiFi模块的射频匹配电路,辅助信号稳定传输;
  4. 电源管理:小型线性电源输出滤波、低电流LED驱动(如指示灯)的电感元件;
  5. 车载低功耗电路:部分车载传感器(温度/湿度)的辅助电路(需确认品牌车规认证,常规产品可覆盖)。

五、性能优势分析

  1. 小体积高集成:0805封装节省PCB空间,适配小型化设备设计趋势;
  2. 低损耗高效率:1.17Ω低[email protected]高Q值,工作频率内损耗极小,提升电路效率;
  3. 性能稳定可靠:±10%精度偏差可控,SRF 25MHz覆盖常见工作频率,电感特性稳定;
  4. 生产兼容性强:贴片封装适配主流SMT设备,自动化贴装降低人工成本与误差。

六、使用注意事项

  1. 电流限制:工作电流不得超过300mA(直流),否则绕组过热、电感值漂移;
  2. 频率限制:电路工作频率≤5MHz(远低于25MHz SRF),避免电感呈容性;
  3. 焊接工艺:回流焊峰值温度230-250℃,时间≤10s,避免高温损坏磁芯;
  4. 存储条件:干燥、无腐蚀性气体环境(湿度≤60%),防止引脚氧化;
  5. 精度余量:电路设计预留±10%偏差余量,避免因偏差导致性能不达标。

七、品牌与可靠性说明

YJYCOIN(益嘉源)专注贴片电感研发,YWLD系列具备:

  • 经过温度循环(-40℃~+85℃,50次)、湿度测试(85℃/85%RH,48h)、振动测试(10-2000Hz,1g);
  • 批量一致性好,参数偏差控制在规格内;
  • 适配消费电子、物联网量产需求,供货稳定。

该产品平衡了小体积与性能,是低功耗电子设备电感选型的实用方案。

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
