# Hybrid Aluminium Electrolytic Capacitor, Vibration-Proof, 120 µF, ± 20%, 50 V, Radial Can - SMD ![Product image](https://novapart.co/image/farnell:4906169RL/) **URL**: https://novapart.co/products/GWC1H121MCXADNGS/hybrid-aluminium-electrolytic-capacitor-vibration **SKU**: GWC1H121MCXADNGS **Manufacturer**: NICHICON **Price**: €0.2630 **Stock**: 10+ **Lead Time**: 151 days (indicative) ## Description The GWC1H121MCXADNGS from NICHICON is a conductive polymer hybrid aluminum electrolytic capacitor featuring a 120 µF nominal capacitance with ±20% tolerance, rated for 50 VDC operation across an extended temperature range of –55°C to +135°C. This surface-mount device employs a radial can construction in a 10 mm diameter × 10 mm height package, integrating both liquid electrolyte and conductive polymer technologies to achieve low equivalent series resistance (ESR) of 20 mΩ maximum at 100 kHz and 20°C. The hybrid construction delivers high ripple current capability—4700 mArms at 125°C and 3000 mArms at 135°C—while maintaining a dissipation factor (tan δ) of 0.10 maximum at 120 Hz. The capacitor exhibits stable impedance characteristics with maximum ratios of 2.0 at –25°C and 2.5 at –55°C relative to 20°C, ensuring predictable performance across thermal extremes. Designed for high-reliability applications, the GWC series meets AEC-Q200 qualification standards for automotive electronics, with demonstrated endurance of 4000 hours at 135°C under combined DC bias and rated ripple current. The component maintains capacitance within ±30% of initial value, ESR within 200% of initial specification, and leakage current below 0.01CV (µA) following life testing. The vibration-resistant construction addresses mechanical stress concerns in harsh environments, while the surface-mount radial format facilitates automated assembly processes. Typical applications include DC-DC converter output filtering in automotive powertrain systems, voltage regulation in LED driver modules, energy storage in industrial motor drives, and bulk decoupling in telecommunications infrastructure where high temperature operation and long service life are critical requirements. ## Datasheet 📄 [Download PDF](https://novapart.co/datasheet/farnell:4906169RL/) ### **CONDUCTIVE POLYMER HYBRID ALUMINUM ELECTROLYTIC CAPACITORS** **GWC** Chip Type, 135°C High Reliability High Reliability, Low ESR,High ripple current.
