Designed for Demanding Power Conditions

GKT-EA and GKT-EB are built to perform in power circuits where temperature, space, and reliability are critical factors. Both series are RoHS compliant and lead-free, making them suitable for global applications.

Key Specifications

• Operating Temperature Range: -55°C to +105°C
• Rated Voltage Range: 2 ~ 25V DC
• Capacitance Range:
  • GKT-EA: 2.2µF ~ 470µF
  • GKT-EB: 6.8µF ~ 680µF
• Endurance Test: 2,000 hours at 105°C
• Low ESR: As low as 4.5mΩ (100kHz, 20°C)
• Ripple Current: Up to 4,800mArms (GKT-EB)

Compact Case Sizes for Flexible Layouts

• GKT-EA Dimensions: 7.3 × 4.3 × 1.9 mm
• GKT-EB Dimensions: 7.3 × 4.3 × 2.8 mm

The shared footprint simplifies layout design, while different heights accommodate varying capacitance needs without compromising board space.

Stable Electrical Characteristics at High and Low Temperatures

Both series demonstrate outstanding temperature impedance stability:

• Z(+105°C)/Z(+20°C) ≤ 1.25
• Z(–55°C)/Z(+20°C) ≤ 1.25

This ensures minimal performance deviation across a wide thermal range — a key requirement for mission-critical systems.

Passed Environmental Tests

Each capacitor series complies with strict environmental reliability testing:

• Humidity Resistance: 500 hrs at 60°C, 90–95% RH (no voltage)
• Surge Test: 1,000 cycles with voltage surge through protective resistor
• Post-test Stability:
  • Capacitance change ≤ ±20%
  • ESR and leakage current ≤ 150% of initial value

Applications (as specified in datasheet)

• System Board
• Display Card
• Small Charger
• Smart TV

These are ideal platforms where heat resistance, ESR control, and form factor matter.
