GYB1H121MCW1GS

The GYB1H121MCW1GS is a conductive polymer hybrid aluminum electrolytic capacitor in a surface-mount can package, offering 120 µF capacitance at a 50 V rating. It targets high-reliability applications that require low equivalent series resistance (ESR), high ripple-handling capability and long-term stability across a wide temperature range.

Designed and qualified for demanding environments, this part combines low ESR and high ripple-current capability with a 10 000-hour endurance at 105 °C, making it suitable for automotive and other robust electronic systems that require durable power decoupling and smoothing components.

Key Features

• Conductive polymer hybrid construction Combines polymer and aluminum electrolytic technologies for reduced ESR and improved ripple performance.
• Capacitance and tolerance 120 µF nominal capacitance with tolerance of −20% to +20% (measured at 120 Hz, 20 °C).
• Rated voltage and dissipation factor 50 V rated voltage; tan δ (DF) 0.10 at 20 °C, 120 Hz for predictable loss characteristics.
• Low ESR and high ripple capability ESR ≤ 28 mΩ at 20 °C/100 kHz; low-frequency ripple current 300 mA at 120 Hz and high-frequency ripple current 2.0 A at 100 kHz.
• Leakage current Leakage current specified at 60 µA (after application of rated voltage under standard conditions).
• Long-life endurance Rated for 10 000 hours at 105 °C under rated conditions (endurance criteria documented in the datasheet).
• Wide operating temperature range −55 °C to 105 °C to support extended-temperature operation.
• Package and mounting Surface-mount radial can (φ10 × 10 L / L: 1 × D: 1 cm) with embossed carrier taping for automated placement; vibration resistant.
• Compliance and qualification AEC‑Q200 rating and RoHS compliant for regulated production environments.

Typical Applications

• Automotive electronic modules Designed for automotive systems where AEC‑Q200 qualification, high ripple handling and long-life at elevated temperature are required.
• Power supply decoupling in harsh environments Low ESR and 2.0 A high-frequency ripple capability support smoothing and decoupling on switch-mode regulator outputs and power rails operating at elevated temperatures.
• High-reliability industrial electronics Long 10 000-hour endurance at 105 °C and vibration resistance make this part suitable for industrial control and instrumentation requiring sustained performance.

Unique Advantages

• Low-loss, low-ESR performance: ESR ≤ 28 mΩ at 100 kHz reduces voltage ripple and power dissipation in high-frequency circuits.
• High ripple-current capability: 2.0 A at 100 kHz and 300 mA at 120 Hz enable effective handling of both switching and low-frequency ripple components.
• Long-term high-temperature endurance: 10 000 hours at 105 °C supports extended field life in elevated-temperature applications.
• AEC‑Q200 qualified and RoHS compliant: Meets industry qualification for automotive use and regulatory environmental requirements.
• Compact SMD can package with taped reel option: φ10 × 10 L form factor and embossed carrier taping simplify automated assembly and conserve board area.
• Predictable leakage and loss characteristics: Specified leakage current (60 µA) and tan δ (0.10 at 50 V, 120 Hz) facilitate reliable design margins.
