1、2.5V Super Farad Capacitor - Ideal for supercapacitor protection boards. 2、Each capacitor is equipped with a protection board, effectively safeguarding it from exceeding voltage limits. 3、The power tube and large copper on the back of the resistor enhance heat dissipation for more stable operation. 4、High-power switch with three 2010 SMD resistors connected in parallel to form a 0.4 ohm resistor (considering heating issues, the continuous voltage limit should not exceed 1A current). 5、Utilizes a high-precision regulator IC as a reference; the standard regulator is 2.5v±50mV (adjustable R4, R5 resistors adjust the pressure limit).
