PTC SMD Thermistors

TDK B59602 and B59603 PTC SMD Thermistors provide thermal management in LED driver circuits. Constructed as ceramic PTC SMD thermistors, these devices feature a maximum operating voltage of 32V_DC, an operating temperature range of -40°C to +125°C/+145°C, and a resistance tolerance of 5% to 50%. TDK PTC thermistors for thermal management in LED driver circuits are ideal for DC/DC converters, home appliances, dimmers, electronic ballasts, and overtemperature protection of power components.
