HHS SERIES - RESISTANCE WELD CRYSTAL The HHS series is the lowest profile HC49/USS and HC49/USSM (surface mount) industry standard crystal, with the same lead spacing as the HC49U/US and encased in the rugged resistance weld package. With a maximum height of only 2.5mm for through hole type and 3.2mm for surface mount, these crystals are both cost effective and ideal for many space limited applications. FEATURES: • Lowest profile (2.5mm / 3.2mm SMD) • Industry standard lead spacing • Resistance welded for good aging • Cost effective OPTIONS: • Extended temp. range • Surface mount package • Insulator • Tighter tolerance option • Tape & Reel ELECTRICAL SPECIFICATIONS PARAMETERS FREQUENCY RANGE FREQUENCY TOLERANCE FREQUENCY STABILITY, REF @ 25°C OPERATING TEMPERATURE RANGE STORAGE TEMPERATURE RANGE SHUNT CAPACITANCE (CO) CONDITIONS MINIMUM MAXIMUM 3.200 70.000 -30* +30* -50* +50* 0°C to +70°C / -40°C to +85°C -30°C to +85°C / -55°C to +125°C 7.0 @ 25°C 3.200 - 70.000 MHz LOAD CAPACITANCE (CL) Per customer spec.
