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。
