Bourns Mini Breaker SD Series (AECQ Compliant)
SD Series Breaker (Surface Mount Thermal Cutoff Device)
Features a wide temperature range (-55°C to 150°C). Suitable for automotive applications.
■Features - Capable of protection against overheating and overcurrent - Wide temperature range of +55 ℃ to +150 ℃ (SD Series) - Ultra-low resistance (stable resistance at maximum) - Option for automatic reset function - AEC Q200 compliant products available (SD Series) tested according to internal standards ■Benefits - High reliability against high-temperature anomalies - Independent overheating protection function that does not require additional protective components - Reduces user safety concerns - Contributes to improving customer quality, brand, and reputation Thermal cutoff (TCO) devices, represented by Bourns' mini breakers, are used as safety measures to prevent overheating and fires caused by overcurrent, such as that from lithium-ion batteries. They maintain a tripped (operated) state at abnormal temperatures and automatically reset when the power is cut and the temperature returns to a safe level. Compared to polymer PTCs and thermal fuses, they provide protection at lower temperatures.
