LED Lighting Solutions

Littelfuse LED Lighting Solutions support all facets of the LED lighting market with innovative solutions that not only meet regulatory standards but also increase equipment safety and reliability. To help protect end-users, Littelfuse works closely with many LED driver IC suppliers, to ensure their evaluation boards and reference designs comply with safety and surge immunity requirements. They also assist LED lighting power supply manufacturers in designing optimal protection schemes for their driver modules. At the OEM level, they cooperate with luminaire and lamp manufacturers to ensure their products are optimally designed for robust surge immunity protection.

瞬态电压抑制器 (TVS) 二极管

Littelfuse TVS（瞬态电压抑制器）二极管是一系列电路保护产品，用于保护电路免受瞬变和过压威胁，如EFT（电快速瞬变）和ESD（静电放电）。雷击、电感负载式开关和ESD会导致数据线路和电路上的传输产生过大的电应力。TVS二极管产品组合有多种表面贴装和通孔电路板安装型号，包括分别高达20kA和30kW的高峰值脉冲电流和峰值脉冲功率选项。Littelfuse TVS二极管受到青睐的原因是响应速度快（低箝位电压）、电容值低、泄漏电流小。TVS二极管有单向（单极）和双向（双极）两种电路配置。

热泵

Littelfuse供应各种用于热泵的元件，包括保险丝、TVS二极管、栅极驱动器等。热泵市场正在迅速增长，这得益于政府为减少温室气体排放和提高能源成本而采取的举措。得益于逆变器驱动电机提高系统效率，热泵可用于各种气候条件。了解Littelfuse技术如何使热泵更安全、更可靠、更节能。由于逆变器驱动的电机提高了系统效率，热泵可用于各种气候条件。这些元件适合用于各种应用，如能源管理、安全系统、暖通空调系统、烟雾探测器和物联网控制设备。Littelfuse采用保护、控制和感测技术，以提高楼宇的可靠性、安全性和能效。
