YWLD2012-150K 贴片电感产品概述

YWLD2012-150K是益嘉源(YJYCOIN)推出的一款0805封装小功率贴片电感,针对小型化电子设备的电源滤波、信号耦合等场景优化设计,兼顾电气性能与体积优势,是消费电子、物联网等领域的常用基础元器件。

一、关键参数详细解析

该电感的核心参数围绕“性能平衡”设计,各指标明确了其适用范围:

  1. 电感值与精度:15μH±10%,15微亨的电感量适配中低频滤波、信号匹配需求,±10%的精度满足大多数商业级电路的元件替换与调试要求,无需过度依赖高精度匹配;
  2. 额定电流:280mA,指电感可持续稳定工作的最大电流,超过该值会导致磁芯饱和,电感量下降并产生额外损耗,此数值适配便携式设备、低功耗传感器等小功率场景;
  3. 直流电阻(DCR):1.82Ω,作为电感的直流损耗指标,该数值在0805封装中处于合理区间——既通过优化绕线工艺降低了电阻(减少发热与功耗),又避免了因过度追求低电阻导致的体积增大;
  4. 品质因数(Q值):[email protected],Q值=感抗/直流电阻,2.5MHz下Q值达15说明电感在该频率下能量损耗低,适合需要高效信号传输的滤波、谐振电路(如蓝牙2.4GHz附近的低频段匹配);
  5. 自谐振频率(SRF):28MHz,电感的固有谐振频率,超过该频率后电感会呈现容性特性,因此YWLD2012-150K的最佳适用频率范围为1kHz~25MHz,覆盖音频、低频射频、电源滤波等常见场景。

二、封装与物理特性

YWLD2012-150K采用0805英制贴片封装(对应公制2012,型号中“2012”即为此含义),尺寸为2.0mm×1.2mm×1.0mm(长×宽×高,典型值),具备以下优势:

  • 小型化适配:体积紧凑,可集成到手机、智能手环、蓝牙耳机等小型设备的高密度PCB中,满足当代电子设备“轻薄化”趋势;
  • 自动化兼容:贴片式设计适配回流焊、波峰焊等自动化生产工艺,焊接兼容性好,无铅焊接符合RoHS环保标准,适合批量生产;
  • 可靠性稳定:封装采用耐高温环氧树脂包封,可承受焊接高温(260℃回流焊峰值),且抗机械振动、耐环境湿度表现优异,适合工业与消费电子的复杂应用场景。

三、电气性能核心优势

YWLD2012-150K的设计聚焦“小功率场景下的性能平衡”,核心优势体现在:

  1. 低损耗设计:Q值[email protected]与DCR1.82Ω的组合,使电感在工作时发热少、效率高,避免因损耗导致的电路功耗增加;
  2. 电流稳定性:280mA额定电流满足大多数低功耗电路的持续工作需求,磁芯采用高品质铁氧体材料,饱和电流(Isat)通常高于额定电流(典型值约350mA),可应对短时间过流冲击;
  3. 频率特性稳定:在1kHz~25MHz范围内电感量变化小,无明显谐振偏移,适合需要稳定阻抗匹配的电路(如电源滤波中的LC滤波网络)。

四、典型应用领域

YWLD2012-150K因体积小、性能均衡,广泛应用于以下场景:

  1. 消费电子:手机、平板电脑的电源滤波(如电池管理模块的EMI滤波)、蓝牙耳机的信号耦合电路;
  2. 物联网(IoT):低功耗传感器节点(如温湿度传感器、运动传感器)的电源管理、射频匹配电路;
  3. 音频设备:便携式音箱、有线/无线耳机的音频滤波(抑制噪声)、分频电路;
  4. 汽车电子(小功率):车载USB充电模块的EMI滤波、车载蓝牙模块的信号处理;
  5. 工业控制:小型PLC的输入输出模块滤波、微型电机驱动电路的电感储能。

五、品牌与品质保障

益嘉源(YJYCOIN)作为国内专业电感制造商,YWLD2012-150K具备以下品质保障:

  • 材料可靠:磁芯采用低损耗铁氧体,绕线采用高导电率铜线,确保电气性能稳定;
  • 生产工艺:全自动化生产流程,每批次电感均经过电感量、DCR、Q值等参数测试,一致性达行业标准;
  • 环保合规:符合RoHS 2.0、REACH等环保指令,无铅无卤,适配全球市场需求。

总结

YWLD2012-150K是一款高性价比的0805封装贴片电感,以“体积小、性能均衡、适用广”为核心特点,覆盖消费电子、物联网、音频等多领域的小功率电路需求,是电子工程师设计小型化设备时的可靠选择。

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.
