– Hermetic Sealing: Protects components from moisture and contaminants
– Thermal Conductivity: Helps in heat dissipation
– Electrical Insulation: Prevents short circuits

Limitations:
– Weight: LSG components may be heavier due to the glass envelope
– Temperature Sensitivity: Glass may exhibit limitations in extreme temperature conditions

Comparing GT vs LSG Technologies

Thermal Conductivity: When it comes to thermal conductivity, Graphite (GT) technology edges out Lead Sealed Glass (LSG). Graphite’s high thermal conductivity allows for efficient heat dissipation in various applications, making it a preferred choice for heat-sensitive components.

Electrical Resistance: Graphite (GT) technology offers superior electrical resistance compared to Lead Sealed Glass (LSG). This makes graphite an ideal choice for electronic applications where good electrical insulation is crucial.

Hermetic Sealing: While Graphite (GT) excels in thermal conductivity and electrical resistance, Lead Sealed Glass (LSG) technology shines in terms of hermetic sealing. LSG provides an excellent seal against moisture and contaminants, making it indispensable in applications where component protection is paramount.

Cost Considerations: Graphite (GT) technology may be more expensive compared to Lead Sealed Glass (LSG), primarily due to the cost of graphite material. However, the superior properties of graphite may justify the cost in certain applications.

Weight and Size: Lead Sealed Glass (LSG) components are typically heavier and bulkier than Graphite (GT) components due to the glass envelope used in LSG technology. This may be a critical factor to consider in applications where weight and size constraints are present.

Environmental Factors: Both Graphite (GT) and Lead Sealed Glass (LSG) technologies exhibit good chemical stability and resistance to harsh environments. However, the choice between the two technologies may depend on specific environmental conditions within the application.
