GYB1H121MCQ1GS

The GYB1H121MCQ1GS is a conductive polymer hybrid aluminum electrolytic capacitor in a surface-mount radial can package, optimized for applications that require low ESR and high ripple-current capability. It provides 120 µF capacitance at a 50 V rating in a compact φ10 × 10 mm SMD form factor and is available for mass production.

Designed for long-term reliability, the device is AEC-Q200 qualified, RoHS compliant, and rated for 10,000 hours at 105°C with an operating temperature range of −55°C to 105°C—making it suitable for demanding automotive and related power electronics environments that need low impedance and sustained ripple performance.

Key Features

• Conductive polymer hybrid design — Combines conductive polymer and aluminum electrolytic construction to deliver low ESR and stable performance under bias.
• High capacitance and voltage — 120 µF nominal capacitance at a 50 V rated voltage for higher-voltage power rails.
• Low ESR — 28 mΩ equivalent series resistance measured at 100 kHz and 20°C, supporting efficient energy delivery and reduced loss at high frequencies.
• High ripple-current capability — Supports 300 mA at 120 Hz (low frequency) and 2.0 A at 100 kHz (high frequency) for demanding ripple and decoupling requirements.
• Long endurance — 10,000 hours life specification at 105°C with specified limits on capacitance change, tan δ and ESR after endurance testing.
• Automotive-grade qualification — AEC-Q200 rating for use in automotive electronic designs where qualification is required.
• Compact SMD can package — φ10×10L size (10 mm diameter × 10 mm length) in an embossed carrier tape for surface-mount assembly and automated production.
• Leakage current specification — Leakage current listed at 60 µA, supporting predictable bias behavior in power circuits.
• Wide operating temperature — Rated from −55°C to 105°C for use across harsh thermal environments.

Typical Applications

• Automotive power rails — Low ESR and 50 V rating make this capacitor suitable for decoupling and smoothing on higher-voltage automotive power rails in ECUs and electronic modules.
• DC–DC converter outputs — High-frequency ripple capability (2.0 A at 100 kHz) and low ESR support output filtering and stability in switching power supplies.
• Long-life electronic modules — 10,000 hours at 105°C and AEC-Q200 qualification address longevity and reliability needs in automotive and similarly demanding systems.

Unique Advantages

• Predictable low-impedance performance: 28 mΩ ESR at 100 kHz yields reduced voltage drop and heating under high-frequency ripple currents.
• Robust ripple handling: Dual specification for low- and high-frequency ripple currents (300 mA @120 Hz, 2.0 A @100 kHz) enables use across a range of power-conversion tasks.
• Automotive-capable endurance: AEC-Q200 qualification combined with a 10,000-hour life at 105°C supports integration into automotive-grade designs.
• Compact SMD form factor: φ10×10 mm SMD can supports high-density PCB layouts and automated assembly via embossed carrier tape.
• Wide temperature range: −55°C to 105°C rating ensures operation across vehicle-relevant temperature extremes.
• Regulatory compliance: RoHS compliant construction for global manufacturing requirements.
