Datasheet
## **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 ## **ESR and OSCILLATION MODE** |1.0 ~ 1.3<br>1.8 ~ 3.0<br>3.1 ~ 3.5<br>**Frequency**<br>**Range MHz**||H49<br>H49<br>H49<br>**Holder**<br>**Type**||SL, Fund.<br>AT, Fund.<br>AT, Fund.<br>**Crystal Cut/**<br>**Oscill.

About Novapart
Novapart is a B2B electronic component broker specialising in stock shortages and cost reduction. We source hard-to-find parts and identify compliant alternatives across a catalogue of 410,000+ components from 500+ manufacturers.
Learn more →Stock Shortage Specialist
When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.
Request a quote →Compliant Alternatives
We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
