GXC1H121MCQ1GS

The GXC1H121MCQ1GS is a conductive polymer hybrid aluminum electrolytic capacitor in a surface-mount radial can (φ10 × 10L) package. It delivers low ESR and high ripple-current capability in a compact SMD form factor optimized for high-reliability environments.

Targeted at designs requiring elevated temperature endurance and sustained ripple handling, this AEC-Q200–rated part provides robust electrical performance across –55°C to 135°C and a 4000-hour life at 135°C.

Key Features

• Capacitance & Voltage — 120 µF rated capacitance with 50 V nominal voltage and ±20% tolerance for power-storage and decoupling needs.
• Low ESR & High-Frequency Performance — 20 mΩ ESR measured at 100 kHz and 20°C, enabling effective high-frequency filtering and low-loss operation.
• High Ripple Current Capability — 450 mA at 120 Hz (low frequency) and 3.0 A at 100 kHz (high frequency), supporting demanding ripple conditions in power circuits.
• Leakage Current — Typical leakage up to 60 µA (measured per datasheet conditions), consistent with hybrid polymer electrolyte behavior.
• High Temperature Endurance — Rated operating range from –55°C to 135°C with an endurance specification of 4000 hours at 135°C.
• Automotive-Grade Reliability — AEC-Q200 qualification and chip-type construction for high-reliability applications.
• Package & Assembly — Surface-mount radial can (SMD) in embossed carrier taping; part configured for mass production with a compact 10 mm × 10 mm footprint and recommended land size 10.3 mm × 10.3 mm.
• Regulatory — RoHS compliant.

Typical Applications

• Automotive electronic modules — AEC-Q200 rating and 135°C endurance make this capacitor suitable for vehicle electronics requiring robust thermal and electrical reliability.
• High-frequency power stages — Low ESR and 3.0 A ripple-current rating at 100 kHz support smoothing and decoupling in high-frequency DC–DC converters and power modules.
• Harsh-environment electronics — Wide operating range (–55°C to 135°C) and long-life specification support extended operation in elevated-temperature assemblies.

Unique Advantages

• High thermal endurance: 4000 hours at 135°C provides confidence for designs exposed to sustained high temperatures.
• Low-loss filtering: 20 mΩ ESR at 100 kHz reduces heat generation and improves power-stage efficiency in HF circuits.
• Robust ripple handling: Combined low- and high-frequency ripple ratings (450 mA @120 Hz, 3.0 A @100 kHz) address mixed-frequency ripple environments.
• Automotive-capable qualification: AEC-Q200 rating enables use in automotive systems and other high-reliability applications.
• Production-ready packaging: Embossed carrier taping and SMD can package support automated assembly and volume manufacturing.
• Regulatory compliance: RoHS conformity simplifies material compliance for global product programs.
