GYB1E331MCQ1GS

The GYB1E331MCQ1GS is a conductive polymer hybrid aluminum electrolytic capacitor in a surface-mount radial can package. It combines low ESR and high ripple-current capability with long-term endurance for demanding power applications.

Designed for automotive and high-reliability systems, this 330 µF, 25 V capacitor delivers low impedance at high frequency and a rated lifetime of 10,000 hours at 105°C, making it suitable for power-rail decoupling, DC–DC converter outputs, and other power-management locations where durability and performance are required.

Key Features

• Conductive polymer hybrid construction — Low ESR and improved high-frequency performance compared to conventional electrolytics.
• High ripple current capacity — 2.5 A at 100 kHz (high-frequency) and 375 mA at 120 Hz (low-frequency) for robust handling of switching and ripple loads.
• Low ESR — 20 mΩ measured at 100 kHz, 20°C, reducing power loss and voltage drop under dynamic loads.
• Long endurance — Rated life of 10,000 hours at 105°C with DC bias plus rated ripple current applied, maintaining capacitance and ESR within specified limits.
• Wide operating temperature range — −55°C to +105°C to support harsh-environment operation.
• Compact SMD radial can package — Size φ10 × 10 L (1.0 cm × 1.0 cm) with embossed carrier taping for automated placement.
• Automotive-grade qualification — AEC-Q200 qualified for use in automotive applications.
• Low leakage current — 82.5 µA (calculated per 0.01·C·V), suitable for power-sensitive circuits.
• RoHS compliant — Conforms to RoHS requirements.

Typical Applications

• Automotive power rails — Bulk and decoupling at DC–DC converter outputs and ECU power supplies where AEC-Q200 qualification and high-temperature endurance are required.
• DC–DC converters — Output filtering and ripple suppression benefiting from low ESR (20 mΩ) and high-frequency ripple capability (2.5 A at 100 kHz).
• Infotainment and body electronics — Stable decoupling under varying load conditions and elevated ambient temperatures up to 105°C.
• Embedded power modules — Compact SMD radial can fits tight layouts while providing long life and reliable performance in continuous operation.

Unique Advantages

• High-frequency performance: 20 mΩ ESR at 100 kHz and 2.5 A high-frequency ripple current support efficient suppression of switching noise.
• Durability under heat: 10,000-hour endurance at 105°C preserves capacitance and limits ESR growth over the product lifetime.
• Automotive-ready: AEC-Q200 qualification enables use in automotive electronic systems that demand proven reliability.
• Compact SMD form factor: φ10 × 10 L package with embossed carrier taping simplifies automated assembly for space-constrained boards.
• Predictable leakage behavior: Leakage current of 82.5 µA (0.01·C·V) provides a verifiable parameter for power-budget calculations.
