The SG200 is a negative temperature coefficient (NTC) thermistor designed for inrush current limiting applications. It offers a nominal resistance of 5 Ohms at 25°C and can handle a maximum steady state current of 7 Amperes. The device has a ±15% resistance tolerance and exhibits a reduced resistance of 70 mOhms when operating at its maximum rated current.
This inrush current limiter is capable of withstanding up to 200 Volts. It features a through-hole design with a diameter of 15.24mm (0.600 inches) and a lead spacing of 7.87mm (0.310 inches). The component carries CSA and UR safety approvals.
SG200 belongs to the SURGE-GARD family from Ametherm, specifically developed to suppress high inrush current surges in power supply circuits. It helps lower the required peak forward surge current rating of rectifiers, reduce fuse failures, and minimize noise. The device is typically used in applications where a low-impedance charging capacitor would otherwise expose the rectifier bridge to excessive current at turn-on.
The part is RoHS3 compliant and REACH unaffected, with an MSL rating of 1 (unlimited). Although the datasheet confirms through-hole dimensions, the part record lists surface mount mounting — this discrepancy should be verified before design-in.
