The TDK Corporation B59970T1100A062 is a PTC thermistor designed for overcurrent protection in telecom applications, suitable for line card applications like POTS and access networks. It features two resistance-matched PTCs within a plastic housing.
This device operates with a maximum fault voltage of 600 V AC and a maximum operating voltage of 135 V AC. The operating temperature range is -40°C to 125°C when V=0, and 0°C to 60°C when V=Vmax. It has a nominal resistance of 70 Ω at 25°C with a tolerance of ±15%.
Key electrical specifications include a sustaining current rating of 150 mA at 25°C and 85 mA at 70°C, and an initial current rating of 70 mA at 25°C and 40 mA at 70°C. Switching times are specified as less than 100s at 0.15A, less than 1s at 1A, and less than 0.15s at 2.5A. The resistance matching in one housing is less than 1.0 Ω.
The B59970T1100A062 is compliant with GR-1089 edition 5 Central Office requirements and telecommunication ports, including lightning surge and AC power fault conditions. It also complies with ITU-T standards for basic-level lightning surges and power induction. The thermistor is housed in a 4-SMD package and is designed for surface mounting. The housing material is UL94-V0 rated, and it holds UL approval to UL 1434.
