Reliable 105°C Solid Capacitors – Kingtronics GKT-EA / GKT-EB

Kingtronics International Company —Inspired by Innovation

When reliability under thermal stress is a must, Kingtronics® GKT-EA and GKT-EB Series deliver trusted performance with proven consistency. Engineered for demanding environments, these SMD multilayer solid capacitors meet global quality standards while offering compact size and stable characteristics across a wide range of power applications.

105°C Rated Performance You Can Rely On

Both GKT-EA and GKT-EB are rated for 2,000 hours at 105°C, ensuring long-term operation in harsh thermal conditions. This makes them an ideal choice for high-density designs where heat management and stability are crucial.

• Temperature Range: -55°C to +105°C
• Endurance: 2,000 hrs @ 105°C
• RoHS & Lead-Free Compliant

Flexible Voltage & Capacitance Options

Series	Capacitance Range	Voltage Range	Size (mm)
GKT-EA	2.2μF ~ 470μF	2V ~ 25V DC	7.3 × 4.3 × 1.9
GKT-EB	6.8μF ~ 680μF	2V ~ 25V DC	7.3 × 4.3 × 2.8

The shared footprint design streamlines PCB layout, while the different heights allow for greater capacitance options without requiring additional space.

Stable ESR and Ripple Handling

With ESR as low as 4.5mΩ and ripple current up to 4,800mArms, GKT-EA and GKT-EB capacitors provide reliable filtering and power stability, even under dynamic load conditions.

Thermal and Environmental Stability

• Impedance Stability:
  • Z(+105°C)/Z(+20°C) ≤ 1.25
  • Z(−55°C)/Z(+20°C) ≤ 1.25
• Humidity Resistance: 500 hrs @ 60°C, 90–95% RH
• Surge Test: 1,000 cycles through resistor
• Post-Test Requirements:
  • Capacitance shift ≤ ±20%
  • ESR / Leakage current ≤ 150% of initial value

These parameters ensure stable electrical behavior in high-humidity or temperature-fluctuating systems.

Applications in Power-Critical Systems

According to the datasheet, GKT-EA and GKT-EB are recommended for:

• System boards
• Display cards
• Small power chargers
• Smart TVs

These capacitors are ideal for designs where long life, thermal resistance, and compact size are required simultaneously.
