## **H49, 49T, H49MJ & 49TMJ CRYSTALS** 

**AT-Cut round crystal blank, optimized for low harmonics Tight tolerances and stabilities available Available <200MHz with 5th overtone mode RoHS compliant** 

## **OUTLINE & DIMENSIONS** 

## **DESCRIPTION** 

H49 crystals are industry-standard crystals. Standard H49 crystals provide a very low cost source of system clock frequency while the part may also be produced with tight tolerances and stabilities. Several holder variants are available. 

## **SPECIFICATION** 

Frequency Range H49: 1.0MHz to 1.3MHz (SL-Cut) 1.8MHz to 200.0MHz (AT-Cut) 49T: 3.1MHz to 200.0MHz Oscillation Mode: _See table_ Load Capacitance (CL): Series or from 8pF to 32pF ( _Customer specified_ ) Drive Level: 100mWatts typ., 500mWatts max. Calibration Tolerance at 25ºC AT-Cut: ±5, ±10, ±20 or ±30ppm SL-Cut: ±50ppm Frequency Stability: _See table_ Shunt Capacitance (C0): 7pF maximum Ageing: ±2ppm maximum Storage Temperature: -50° to +105°C Crystal Holder: Resistance-weld hermetic seal Supply format: Bulk pack RoHS Status: RoHS Compliant
