L2SC2412KQLT1G 是乐山无线电(LRC)推出的一款通用 NPN 双极结型晶体管(BJT),采用 SOT-23 小封装,面向低功耗开关与小信号放大应用。器件支持最高集电极电流 150 mA、集射极击穿电压 50 V,特征频率 fT 达到 180 MHz,在体积受限和成本敏感的应用中表现稳定可靠。
L2SC2412KQLT1G 在直流电流增益和频率响应之间取得良好平衡,hFE ≈ 120 使其在小信号放大器和前置放大级中能提供稳定增益;fT=180 MHz 则允许在几十兆赫兹范围内进行带宽设计。Ic=150 mA 与 VCE(sat)=400 mV 的组合,使其可用作小电流开关驱动或低功耗继电器/继电器式负载的驱动器,但需注意 Pd 仅 200 mW,持续开通时要评估功耗和 PCB 散热能力。
SOT-23 封装体积小,便于高密度 PCB 布局,但散热能力有限。建议:
型号:L2SC2412KQLT1G
品牌:LRC(乐山无线电)
封装:SOT-23
数量:1 个(可按需求批量订购并选择卷带/盘装等包装形式)
如需在电路板上实现可靠运行,建议在样机阶段以真实工作条件做功耗与热仿真验证,并参照厂方完整数据手册查看典型测试条件与极限参数。若需要针对具体电路的偏置建议或原理图示例,可提供工作电源电压与负载条件,我方可给出更精准的设计指导。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
