TAIYO YUDEN LB2012T680M 绕线片式电感产品概述

一、产品基本定位与封装特性

TAIYO YUDEN(太诱)LB2012T680M是一款小型化绕线片式电感,专为紧凑空间内的电源管理、滤波及EMI抑制设计。其采用行业标准0805封装(太诱内部型号以LB2012标识,对应尺寸2.0mm×1.2mm×1.0mm),符合表面贴装(SMT)工艺要求,可直接集成于自动化生产流程,无需额外引脚处理,有效节省PCB布局空间,适配便携式、小型化电子设备的高密度设计需求。

二、核心电气参数详解

该电感的关键参数明确了其适用场景与性能边界,具体如下:

  1. 电感值与精度:标称电感值为68μH,精度±20%,满足多数通用电路的电感量需求(如电源滤波、LC谐振回路的基础配置),无需额外高精度匹配即可实现稳定功能。
  2. 额定电流与功耗:最大额定直流电流为50mA(指电感温升不超过典型值时的允许电流),直流电阻(DCR)为6Ω。结合参数计算,额定电流下的功耗仅为(I^2R=(0.05A)^2×6Ω=15mW),属于低损耗设计,不会显著增加电路整体功耗。
  3. 自谐振频率(SRF):典型自谐振频率为10MHz。需注意:电感的实际特性由频率决定——低于10MHz时呈感性,高于10MHz时因寄生电容主导呈容性,因此应用时需将工作频率控制在10MHz以下,以保证电感功能。

三、关键性能特点

  1. 小型化与高集成度:0805封装体积仅为2.0×1.2×1.0mm,重量轻(约0.02g),可适配手表、耳机等超小型设备的PCB布局,支持高密度集成设计。
  2. 稳定的电感特性:采用绕线工艺制造,电感值一致性良好,±20%精度覆盖了多数消费电子、IoT终端的基础需求,避免因电感量偏差导致的电路性能波动。
  3. 宽温度适应性:太诱电感通常支持**-40℃~+85℃**的工作温度范围(该系列通用规格),可满足户外、工业级环境下的稳定运行(如物联网传感器节点)。
  4. EMI抑制能力:绕线结构对高频噪声具有一定抑制作用,可辅助减少电路中的电磁干扰,适配对EMI要求较高的设备(如无线耳机、蓝牙模块)。

四、典型应用场景

LB2012T680M的参数特性使其适配以下场景:

  1. 便携式消费电子:智能手机、蓝牙耳机、智能手表的电源滤波电路(如电池供电回路的纹波抑制)、DC-DC转换的储能电感(小电流降压/升压模块)。
  2. 物联网终端:传感器节点(如温湿度、运动传感器)的电源管理模块,低功耗电路的滤波与储能。
  3. 小型电子模块:音频设备的滤波回路、遥控器的信号处理电路、LED驱动的辅助电感。

五、选型与使用注意事项

  1. 频率匹配:工作频率需低于10MHz,避免因自谐振导致电感特性失效(如高频下呈容性,无法实现滤波或储能)。
  2. 电流限制:电路中通过的直流电流不得超过50mA,若需更大电流需选型更高额定电流的同系列产品。
  3. 焊接工艺:需遵循贴片电感的回流焊规范(典型温度曲线:预热150-180℃,峰值230-250℃),避免过高温度损坏绕线结构或封装。
  4. 存储与运输:需存放在干燥环境(湿度≤60%),避免受潮导致DCR增大或性能下降;运输时需防止机械冲击,避免电感变形。

该产品凭借小体积、低损耗、稳定特性,成为消费电子与IoT终端电源管理的实用选型。

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
