Product Overview
M.D.L. GT Series 105°C Snap-in Terminal Type Aluminum Electrolytic Capacitors
The GT and GK Series share the same snap-in mounting format and general application areas. Their primary differences are the temperature rating and materials used in production.
The GT Series uses aluminum foil, high-temperature electrolyte, sealing materials and related components selected for 105°C operation. These higher-grade materials increase the manufacturing cost but provide greater thermal margin for equipment with higher internal temperatures, limited cooling or extended operating periods.
Low impedance and high ripple-current capability help reduce internal heating while supporting stable power filtering, energy storage and transient-current delivery. Snap-in terminals simplify PCB positioning and improve assembly efficiency.
Key specifications:
- Operating temperature: −40°C to +105°C
- Working voltage: 10VDC to 500VDC
- Nominal capacitance: 47μF to 20,000μF
- Capacitance tolerance: ±20% at 120Hz and 25°C
- Load life: 2,000 hours at 105°C
Typical applications include:
- High-power audio and power-amplifier supplies
- Professional audio power filtering
- Switching power supplies
- Uninterruptible power supplies
- Inverters and frequency-conversion equipment
- Industrial control and automation systems
- Communication and server power supplies
- Electronic equipment with higher internal temperatures or limited cooling
