General Notes: NOTES: 1. Tolerances on 3 place decimals ±0.020(.51) except as noted. 2. Dimensions in inches over millimeters. 3. Solder Tabs: .002 ± .0005(.05 ± .01) thick iron nickel alloy, gold plated .0005(.0012) thick min. 1. The QJE-2-.312GG is ideal for high power applications. A high thermal conductivity dielectric is used to disperse heat insuring high performance and reliability. 2. The Filmbrid Sandwich Package is sealed under heat and pressure insuring the printed substrates and low-loss dielectric laminates are permanently bonded together. This minimizes the effects of dirt and moisture and prevents separation under shock and vibration. 3. Custom units are readily available to accommodate special bandwidth and frequency requirements. 02Feb07 For further information contact MERRIMAC / 41 Fairfield Pl., West Caldwell, NJ, 07006 / 973-575-1300 / FAX 973-575-0531
