Amphenol Thermometrics

<p>The CL-140A is an NTC inrush current limiter from Amphenol Thermometrics designed to suppress surge currents in switching power supplies, fluorescent lamp inverters, and motor circuits. Its cold resistance at 25°C is 50 Ω with a tolerance of ±25%. At rated current of 1.1 A, the hot resistance drops to 890 mΩ, enabling efficient steady-state operation with minimal power loss.</p><p>&nbsp;</p><p>This radial leaded through-hole component has a diameter of 11.4 mm and a lead spacing of 6.35 mm, suitable for PCB mounting. It operates over a wide temperature range of -50°C to 175°C and carries UL recognition per UL 1434 (File E82830). The thermistor's solid-state construction provides excellent mechanical strength and low cost for inrush suppression applications.</p>
