YWLD1608-1R5K 贴片电感产品概述

一、产品基本信息

YWLD1608-1R5K是益嘉源(YJYCOIN)推出的0603封装通用贴片电感,型号命名遵循行业标准:

  • “YWLD”为品牌电感系列标识;
  • “1608”对应公制封装尺寸(1.6mm×0.8mm,即英制0603封装);
  • “1R5”表示标称电感值1.5μH;
  • “K”代表精度等级±10%。

核心基础参数如下:

参数项 规格值 标称电感值 1.5μH 精度 ±10% 额定直流电流(Idc) 600mA 直流电阻(DCR) 520mΩ 品质因数(Q值) [email protected] 自谐振频率(SRF) 160MHz

二、关键性能参数解析

(1)电感值与精度的应用适配性

1.5μH±10%属于中小功率通用型电感,覆盖多数消费级、工业级设备的常规需求:

  • 电感值适配小功率电源滤波、射频匹配的频率范围;
  • ±10%精度无需额外校准,平衡了性能与成本,适合批量生产场景。

(2)额定电流与低DCR的优势

  • 额定电流600mA:指电感持续工作时,温升不超过行业标准(≤50℃)的最大直流电流,若电流超限会导致电感饱和(电感值骤降)或热失效;
  • DCR仅520mΩ:直流电阻是线圈导线的损耗,低DCR意味着相同电流下功耗更低(P=I²·R),尤其适合电池供电设备(如蓝牙耳机)的效率优化。

(3)Q值与自谐振频率的高频特性

  • Q值[email protected]:Q值=感抗(XL)/等效串联电阻(ESR),是衡量高频损耗的核心指标;16的Q值表明在7.9MHz频率下,电感信号损耗低,适合蓝牙、WiFi等短距离无线通信的匹配网络;
  • 自谐振频率160MHz:电感寄生电容与电感值形成谐振,谐振点处电感呈纯阻性;实际应用需避开160MHz±10%范围,否则无法发挥电感特性。

三、封装与物理特性

YWLD1608-1R5K采用0603贴片封装,物理尺寸为1.6mm(长)×0.8mm(宽)×0.8mm(高),适配表面贴装工艺(SMT),优势显著:

  1. 小型化:比传统插件电感缩小70%以上,适配智能手机、智能手环等便携设备的紧凑布局;
  2. 一致性:贴片工艺减少人工误差,批量产品参数偏差极小;
  3. 抗干扰:表面贴装降低电磁干扰(EMI),满足电磁兼容(EMC)要求。

四、典型应用场景

结合参数特性,该电感主要适用于以下场景:

  1. 便携式设备电源滤波:智能手机、平板电脑的电池供电回路纹波抑制,低DCR减少功耗;
  2. 短距离无线通信:蓝牙4.0/5.0、WiFi 2.4GHz模块的射频匹配,Q值满足信号传输损耗要求;
  3. 小功率DC-DC转换:5V转3.3V、3.3V转1.8V降压电路的储能电感,600mA电流覆盖多数小负载;
  4. 物联网终端:智能传感器、智能家居设备的信号滤波与匹配,微型化封装适配设备小型化趋势。

五、应用注意事项

  1. 频率限制:工作频率需避开160MHz(建议≤100MHz或≥200MHz),防止自谐振;
  2. 电流管控:持续电流≤600mA,脉冲电流需降额至70%-80%;
  3. 焊接工艺:遵循回流焊曲线(峰值温度≤245℃,时间≤30s),避免热冲击;
  4. 存储环境:温度-40℃~+85℃,湿度≤60%,防止引脚氧化。

YWLD1608-1R5K凭借小型化、低损耗、高Q值的特性,成为消费电子、物联网领域的高性价比通用电感选型。

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
