GYE1J121MCW1GS

The GYE1J121MCW1GS is a conductive polymer hybrid aluminum electrolytic capacitor designed for high‑reliability, high‑temperature applications. It is a chip‑type, surface‑mount can that combines high capacitance with low ESR and high ripple‑current capability.

Engineered for demanding environments, the part supports automotive use (AEC‑Q200 qualified), long life at elevated temperature, and RoHS compliance for regulated designs.

Key Features

• High‑temperature endurance: Rated for operation from -55°C to 125°C with a specified lifetime of 4000 hours at 125°C, supporting sustained performance in hot environments.
• Low ESR and high ripple capability: ESR of 20 mΩ at 100 kHz and ripple current ratings of 450 mA at 120 Hz and 3 A at 100 kHz reduce heating and support high dynamic current demands.
• Polymer hybrid construction: Conductive polymer hybrid aluminum electrolytic architecture delivers high capacitance in a chip‑type SMD package.
• Robust electrical rating: 120 μF capacitance at 63 V with ±20% tolerance, offering substantial energy storage for decoupling and smoothing tasks.
• Automotive qualification and regulatory compliance: AEC‑Q200 qualification and RoHS compliance (2011/65/EU, (EU)2015/863) support regulated and automotive program requirements.
• Compact SMD can package: Package dimensions L: 1.25 × D: 1.00 cm and recommended land size 1.03 × 1.03 cm enable space‑conscious board layouts.

Typical Applications

• Automotive systems: Suitable for use in automotive electronics where AEC‑Q200 qualification and high‑temperature endurance are required.
• Power management in high‑temperature environments: Low ESR and high ripple current ratings make the capacitor well suited for power filtering and energy buffering under elevated ambient temperatures.
• Industrial electronics: Long life at 125°C and robust leakage and endurance characteristics support reliable operation in demanding industrial control and power subsystems.

Unique Advantages

• Extended high‑temperature life: 4000‑hour rating at 125°C reduces frequency of replacements and supports long‑life product designs.
• Improved thermal and electrical performance: Low ESR (20 mΩ at 100 kHz) and high ripple handling (3 A at 100 kHz) lower internal dissipation and help maintain capacitance stability under dynamic load.
• Standards and compliance: AEC‑Q200 qualification and RoHS conformity simplify qualification for regulated markets and automotive programs.
• Compact SMD form factor: Chip can package with a small footprint (1.25 × 1.00 cm) supports dense PCBs and automated assembly.
• Predictable electrical behavior: Specified leakage current (≤0.01CV μA after 2 minutes at 20°C) and defined endurance/shelf‑life conditions aid reliability modeling and qualification testing.
