General Specifications
   Package / Form Factor       
   Your choices are...         
   Through Hole Technology (THT)       Through hole technology (THT) mounts components on a printed circuit board (PCB) by inserting component leads through holes in the board and then soldering the leads in place on the opposite side of the board. 
   Connectorized       Connectorized devices attach with coaxial or other types of connectors. 
   Waveguide Assembly       Waveguide assemblies are used in microwave waveguide systems. They consist of a hollow metallic conductor with a rectangular, elliptical, or circular cross-section. Some conductors contain solid or gaseous dielectric materials. 
   Surface Mount Technology (SMT)       Surface mount technology (SMT) adds components to a printed circuit board (PCB) by soldering component leads or terminals to the top surface of the board. SMT components have a flat surface that is soldered to a flat pad on the face of the PCB. Typically, the PCB pad is coated with a paste-like formulation of solder and flux. With careful placement, SMT components on solder paste remain in position until elevated temperatures, usually from an infrared oven, melt the paste and solder the component leads to the PCB pads.   Industry-standard pick-and-place equipment can mount SMT components quickly, accurately, and cost-effectively. SMT is a widely used alternative to mounting processes that insert pins or terminals through holes and solder leads into place on the opposite side of the board.

   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Features / Standards       
   Your choices are...         
   RoHS Compliant       Restriction of Hazardous Substances (RoHS) is a European Union (EU) directive that requires all manufacturers of electronic and electrical equipment sold in Europe to demonstrate that their products contain only minimal levels of the following hazardous substances: lead, mercury, cadmium, hexavalent chromium, polybrominated, biphenyl and polybrominated diphenyl ether. RoHS will become effective on July 1, 2006. 
   Lead Free       Devices do not contain lead (Pb) in any form. The electronics industry is working to provide lead-free products in response to concerns about the environmental impact of using lead in solder finishes. These efforts are in response to both customer demands and government directives to decrease the amount of waste from consumer electronics. Officially, products that are lead free have less than 1000 ppm lead by weight. 
   Programmable       The frequency of the device can be selected and programmed by the user. 
   Military Standard       The device is suited for military applications. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

Performance
   Oscillation Frequency       This is the nominal value of the oscillator frequency. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Total Frequency Stability       Total frequency stability is the maximum frequency deviation from the nominal value for all conditions (e.g., temperature, supply voltage, etc.). It is usually measured in parts per million (ppm). 
   Search Logic:      All matching products will have a value less than or equal to the specified value.
   Frequency Tolerance       Frequency tolerance or frequency error is the allowed, stated deviation of the nominal oscillation frequency. Generally, this amount is expressed as a percentage (%). 
   Search Logic:      All matching products will have a value less than or equal to the specified value.
   Load Capacitance       Load capacitance is the total capacitance across the crystal. 
   Search Logic:      All matching products will have a value less than or equal to the specified value.
   Drive Level       Drive level is the total power that the crystal dissipates internally. 
   Search Logic:      All matching products will have a value less than or equal to the specified value.
   Max ESR       Equivalent series resistance (ESR) is the equivalent Ohmic resistance when a device is in operation. Typically, this is expressed as a maximum amount. 
   Search Logic:      All matching products will have a value less than or equal to the specified value.
   Operating Temperature       This is the full-required range of ambient operating temperatures. 
   Search Logic:      User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria.
