Thick Film Power Resistors Type BDS300 Series Type BDS300 Series Characteristics Electrical Resistance Values: Resistance Tolerance: Temperature Coefficient: Power Rating: Capacitance / Mass: Capacitance / Parallel: Inductance: Maximum Working Voltage: Insulation Voltage: Single Shot Voltage: Insulation Resistance: Partial Discharge: The BDS300 has been designed for use as a snubber resistor where compensatation is required for C-R peaks in traction power supply equipment. The High alumina metallized ceramic is ideally suited Characteristics Environmental to allowing maximum connection to Operation Temperature: Short Time Overload: the main heatsink. The resin filled epoxy casing provides large creep distance to mass, large air distance between the terminals and high R505 to 100K 5% or 10% 150ppm/C (others upon request) 300W at 85C 110 pF 40 pF 80 nH 5,000VDC 6kVrms, 50Hz,1Min. up to 12 kV Normwave (1.5/50 secs) 10G Min. at 500V 3kVrms <10pC -55C to +150C 1.5x rated power = 450W at 70C for 10 sec, R = 0.4% max. Characteristics Mechanical insulation resistance, whilst the Terminal Size: Max. Torque for Contacts: Max. Torque for Mounting: Creeping Distance: Air Distance: design of the Resitive element element allows for perfect current yeild over the entire component.
