The B57235S0509M000 is a leaded NTC thermistor from TDK Electronics, specifically designed for inrush current limiting applications. It features a nominal resistance of 5Ω at 25°C with a tolerance of ±20% and a maximum current rating of 4.2A. The device is housed in a 9.5mm diameter radial leaded package with kinked tinned copper leads, suitable for through-hole mounting.
Under typical operating conditions, the thermistor can handle a maximum power dissipation of 1.8W at 25°C. The dissipation factor is approximately 9 mW/K in air, with a thermal time constant of about 60 seconds. These parameters make it suitable for repetitive inrush current limiting in power supplies and motor start circuits.
The component is rated for an operating temperature range of -55°C to +170°C, derived from climatic category 55/170/21 (IEC 60068-1). The coating is flame retardant to UL 94 V-0. It carries approvals from CQC, UL, and VDE, confirming compliance with relevant safety standards.
