Indoor LED Lighting Circuit Protection

Littelfuse Indoor LED Lighting Circuit Protection ensures a long operating life, increased energy efficiency, and safety. LEDs can be damaged by voltage or current surges, and by extreme temperatures. Littelfuse circuit protection technology protects LED assemblies from potential damage. Important circuit protection technologies include metal-oxide varistors (MOVs), transient voltage suppression (TVS) diodes, and fuses.

工業通訊和控制

Littelfuse工業通訊和控制為RS-485和乙太網應用提供保護。工業RS-485能驅動多個連接埠、具有10Mbps及1500m長距離傳送。工業乙太網提供100m長距離傳送、額定30W PoE+及額定1Gbps快捷速度。Littelfuse工業通訊和控制RS-485及乙太網裝置理想適用於能源儀表、工廠自動化、風控制及人機介面。

RS-485 ESD, Lightning, & Power Fault Protection

Littelfuse RS-485 ESD, Lightning, and Power Fault Protection feature polymeric positive temperature coefficients (PPTCs) that can protect against short circuit and power crosses. The RS-485 product line includes the resettable PPTCs, TVS diodes, GDTs, and SIDACtor series. The TVS Diode Arrays and SM712 series are specifically designed to protect RS-485 applications from ESD, EFT, and lightning-induced surges. When lightning occurs, the SIDACtor will react by causing voltage to increase across PPTC until GDT fires.

PolySwitch自復式裝置

Littelfuse PolySwitch 和 POLY-FUSE裝置均為聚合物正溫度係數 (PPTC) 裝置，可提供替代的自復式過電流保護解決方案，協助降低保固、服務與維修方面的成本。由於電流增加，PTC的電阻會隨溫度提高而增加。元件的設計能限制超出安全範圍的電流，維持在恆定安全的電流等級，並在故障排除且溫度恢復到安全等級後，自動「重置」電阻。PTC可在發生故障電流後自我重置，很適合用於操作位置不方便的電路。PTC經常用於電路保護的應用，這類應用的敏感元件持續受到過電流狀況的威脅。此外，此類元件也適合經常發生過電流狀況或需要不間斷運作的環境。自復式PTC (PPTC) 主要用於消費性電子裝置、電源線、電信、I/O連接埠、製程控制及醫療設備的保護應用。

PolySwitch Telecommunication Resettable PTCs

Littelfuse PolySwitch Telecom Resettable PTCs are designed to protect against short-duration high-voltage fault currents typically found in telecom applications. These components help provide protection against damage caused by power cross and power induction surges, as well as help improve the reliability of customer premise and network equipment worldwide. Littelfuse PolySwitch Telecom Resettable PTCs are compatible with high-volume electronics assembly, assist in meeting regulatory equipment requirements, help improve line balance, and are applicable for legacy POTS and modern digital communications equipment. These devices are available in chip, surface-mount, or radial-leaded configurations.
