The B59751B0120A070 is a 2-pin PTC Thermistor with lead-free terminals. This B597 series thermistor is marked with manufacturer's logo, date code and type designation stamped on in black. Self-protecting in case of malfunction of short-circuit relay or internal short circuit of capacitor. Inrush current limiters are not damaged when directly connected to Vmax even without additional current limitation. Soldering can use rosin-type flux or non-activated flux. The soldering due to insufficient preheating may cause ceramic cracks. Suitable for over-current protection, short circuit protection, inrush current limiter (charging resistor) for smoothing and DC link capacitors and to replace high-power fixed resistors for capacitor charging.
