GYC1H121MCQ1GS

The GYC1H121MCQ1GS is a surface-mount conductive polymer hybrid aluminum electrolytic capacitor in Nichicon’s GYC series, designed for high-temperature, high-reliability power applications. It delivers a 120 µF capacitance at 50 V with low equivalent series resistance and rated endurance for operation up to 135°C.

Engineered for demanding environments, this part targets applications that require robust ripple handling, low loss, and long operational life—particularly in automotive and industrial power electronics where temperature and reliability matter.

Key Features

• Capacitance & tolerance — 120 µF nominal with a tolerance of −20% to +20% measured at 20°C, 120 Hz.
• High-temperature endurance — Rated for operation from −55°C to +135°C with an endurance specification of 4000 hours at 135°C.
• Low loss (tan δ) — tanδ of 0.1 at 20°C, 120 Hz, supporting efficient energy storage with controlled dissipation.
• Low ESR — ESR specified at 28 mΩ measured at 20°C, 100 kHz for reduced voltage drop and heat generation under AC stress.
• High ripple capability — Low-frequency ripple current 240 mA at 120 Hz and high-frequency ripple current 1.6 A at 100 kHz to support switching supplies and converters.
• Leakage current — Specified leakage current of 60 µA (measured per product test conditions).
• Package & mounting — Surface-mount radial can, size φ10 × 10L (1.0 × 1.0 cm) with embossed carrier taping for automated assembly; recommended land size L: 1.03 × W: 1.03 cm.
• Standards & compliance — AEC‑Q200 qualified and RoHS compliant for regulated and automotive-grade designs.

Typical Applications

• Automotive electronics — Power smoothing and decoupling in modules that require AEC‑Q200 qualification and extended high-temperature endurance.
• DC–DC converters and power supplies — Low ESR and high ripple current capability help reduce output voltage ripple and thermal stress in switching regulators.
• Industrial power systems — Suitable for power conditioning in harsh environments thanks to a wide operating temperature range and long endurance.
• On-board power decoupling — Compact surface-mount package provides bulk capacitance and transient buffering on densely populated PCBs.

Unique Advantages

• High-temperature reliability: 4000 hours at 135°C provides predictable long-term performance in elevated-temperature applications.
• Efficient filtering with low ESR: 28 mΩ ESR at 100 kHz minimizes losses and heat generation in high-frequency environments.
• Strong ripple handling: Combined low- and high-frequency ripple ratings (240 mA @ 120 Hz; 1.6 A @ 100 kHz) support both legacy and high-speed switching power systems.
• AEC‑Q200 qualification: Built to meet automotive-grade reliability requirements for designs that demand proven component robustness.
• Surface-mount, assembly-ready: Radial can SMD in embossed carrier taping streamlines placement and soldering in automated manufacturing.
• Regulatory readiness: RoHS compliance simplifies use in regulated markets and products.
