250 Watt BDS250 Series
From TE Connectivity, the BDS250 series of thick film power resistors offer a virtually inductance free solution, with inductance of less than 40 nH. With a wide range of different resistance options and low tolerance of only 1%, these power resistors allow for flexibility within your designs. A power rating of 250 W in a 67 x 60 mm casing ensures high power density over a range of ohmic values.
Features and Benefits:
Available in multiple configurations and multi-resistor packages
2 or 4 easy to connect terminals
Optimum stability
Space saving solution for demanding creep and clearance requirements
Less than 10pC at 7.5 kV partial discharge guarantees quality, excellent reliability and a long life span
Product Applications:
Suitable applications for these thick film power resistors include snubbing and filtering. BDS100 power resistors can be used in high frequency and high-voltage applications and can also be used as balancing resistors (in a multi-resistor package).
