Thick Film Power Resistors Type BDS100 Series Key Features 2 � 100W in a 9.5cm footprint • Gives an impressive power density of 2 10.5W/cm � Virtually inductance-free • Inductance < 40nH � Wide resistance range: 0.47Ω to 1MΩ • Coupled with 1% tolerance gives ultimate design flexibility � Multiple terminal configurations and multi-resistor packages • The space saving solution � Partial discharge <10pC at 2kV • Guaranteeing quality, With less than 40nH inductance and a 100Watt power rating in an easy-mounting reliability and long life 38mm x 25mm Isotop case, the BDS100 offers high power density over a wide range of ohmic values (R47 – 1M0) and benefits from 10 years experience in the field. Available in 6 resistor configurations with 2 or 4 easy to connect terminals, the resistors are made from Applications quality materials for optimum reliability and stability with very low partial discharge. � Snubbing TE Connectivity can test resistors to conform to relevant customer specifications, and will (Low inductance) advise on the use of resistors for pulse energy and high voltage applications (HV designs � Balancing Resistor available). Resistors with alternative terminations or flying leads are available, and custom (Multi-resistor package) designs are welcome. This product is available via distribution. � Filter (Low inductance) � High Voltage Characteristics -Electrical � High Frequency Resistance Range: R47 - 1MO Resistance Tolerance: ± 10%, 5% (Tighter by discussion) TCR: R<1Ω ± 250ppm/°C R>1Ω ± 150ppm/°C Rated Power: Heatsink: 115°C / 100°C / 60°C 25W / 50W / 100W Capacitance: Parallel 15pF To Earth 40pF Series Inductance: 40nH (Maximum) Limiting Element Voltage: (100W or Less) 500Vdc/ac rms Isolating Voltage: (Terminal to Heatsink) 2.5kVac rms Single Shot Voltage: 1.5/50ms 4kV Insulation Resistance: (at 500V dc) >100GΩ Partial Discharge: at 2kV <10pC Heat Dissipation: Although the use of proprietary heat sinks with lower thermal resistance is acceptable, up rating is not recommended. The use of proprietary heat sink compound to improve thermal conductivity is essential.
