GYG1E121MCQ1GS

The GYG1E121MCQ1GS is a conductive polymer hybrid aluminum electrolytic capacitor from Nichicon’s GYG series, engineered for high-reliability applications that require low ESR and high ripple-current capability. With a 120 µF capacitance at 25 V and a rated operating range of -55°C to 125°C, it targets designs that demand sustained performance in elevated-temperature environments.

Key value propositions include a long endurance of 4000 hours at 125°C, AEC-Q200 qualification for demanding applications, and RoHS compliance—making the part suitable for automotive and other high-reliability systems where thermal endurance and stable electrical characteristics matter.

Key Features

• Capacitance & Voltage — 120 µF rated capacitance at 25 V with ±20% tolerance, providing bulk energy storage in a compact SMD package.
• High-Temperature Endurance — Qualified for operation from -55°C to 125°C with a guaranteed life of 4000 hours at 125°C, supporting prolonged high-temperature use.
• Low ESR and High Ripple Handling — ESR of 50 mΩ at 100 kHz, with ripple current ratings of 210 mA at 120 Hz and 1.4 A at 100 kHz, enabling effective smoothing and decoupling at both low and high frequencies.
• Reliability Qualification — AEC-Q200 qualified for use in demanding environments and applications that require component-level reliability validation.
• Surface-Mount Can Package — Radial, can-style SMD package with compact footprint (L: 5.8 × D: 6.3 mm) and recommended land size of 6.6 × 6.6 mm for PCB integration.
• Regulatory Compliance — RoHS-compliant (2011/65/EU, (EU)2015/863) for regulatory and environmental requirements.

Typical Applications

• Automotive Electronics — Suitable for automotive modules and systems that require components qualified to AEC-Q200 and capable of sustained operation up to 125°C.
• Power Conversion and Regulation — Used for output smoothing and decoupling in power supplies where low ESR and high ripple current at 100 kHz improve voltage stability.
• Industrial High-Temperature Systems — Fits industrial electronics operating in elevated ambient temperatures that need durable capacitance and predictable end-of-life behavior.
• High-Frequency Filtering — Low ESR at 100 kHz and specified high-frequency ripple handling make it suitable for filtering in high-frequency switching applications.

Unique Advantages

• Long High-Temperature Life: 4000 hours at 125°C provides predictable endurance for designs subject to sustained elevated temperatures.
• High Ripple Capability: 1.4 A ripple current at 100 kHz and 210 mA at 120 Hz reduce voltage ripple and thermal stress in power stages.
• Low ESR Performance: 50 mΩ ESR at 100 kHz minimizes losses and improves transient response in decoupling and output applications.
• AEC-Q200 Qualified: Component-level qualification supports deployment in reliability-sensitive systems, including automotive electronics.
• Compact SMD Can Format: Small footprint (5.8 × 6.3 mm) with defined land pattern (6.6 × 6.6 mm) simplifies PCB layout for space-constrained designs.
• Regulatory Ready: RoHS compliance supports environmental and regulatory requirements for modern product development.
