QBS SERIES - 120 WATT
Rev. 04/2001
DESCRIPTION QBS single output DC/DC converters provide up to 120 Watts of output power in an industry standard, quarter-brick footprint. The QBS converters feature open-frame packaging, along with planar magnetics to provide maximum useable power with minimal thermal constraints. The QBS is especially suited to telecom, networking, and industrial applications, and is fully compatible with production board washing processes.
FEATURES * "Quarter-Brick" * High Power Density Up To 120W * Open-Frame Packaging * 100C Baseplate Operation * Water Washable * Outputs From 2.5V to 15V * 1500V Isolation * Positive or Negative Enable Logic
