GYC1E331MCQ1GS

The GYC1E331MCQ1GS is a conductive polymer hybrid aluminum electrolytic capacitor in a surface-mount chip-style can (φ10 × 10 mm). It provides 330 µF capacitance at a 25 V rating with polarized mounting and is offered in embossed carrier taping for automated assembly.

Designed for high-temperature, high-reliability applications, this Nichicon GYC-series device supports operation from −55 °C to +135 °C, AEC-Q200 qualification, and an endurance rating of 4000 hours at 135 °C—making it suitable for demanding power and automotive electronics where sustained ripple performance and low ESR matter.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance at a 25 V rated voltage with a tolerance of −20% to +20% for bulk energy storage and decoupling.
• Low ESR & High-frequency Performance — ESR of 20 mΩ measured at 20 °C/100 kHz supports low-loss operation and effective high-frequency decoupling.
• High Ripple Current Capability — Handles 300 mA at 120 Hz (low frequency) and 2.0 A at 100 kHz (high frequency), enabling robust performance under AC ripple loading.
• Thermal Endurance — Rated for operation from −55 °C to +135 °C with an endurance life of 4000 hours at 135 °C, suitable for prolonged high-temperature use.
• Loss Characteristics — Dissipation factor (tan δ) of 0.14 at 20 °C, 120 Hz for the 25 V rating, supporting predictable loss behavior in AC conditions.
• Leakage Current — Specified leakage current of 82.5 µA after rated voltage application, enabling predictable standby currents in designs.
• Package & Assembly — Surface-mount radial can (SMD) in φ10 × 10 mm size with recommended land pattern 10.3 × 10.3 mm; supplied in embossed carrier taping for reel-fed placement.
• Compliance & Qualification — AEC‑Q200 qualified for automotive-grade reliability and RoHS compliant.

Typical Applications

• Automotive power electronics — Bulk filtering and decoupling in ECUs and power distribution modules where 135 °C tolerance and AEC‑Q200 qualification are required.
• DC–DC converters — Output smoothing and high-frequency decoupling for converters that demand low ESR and high ripple capability.
• Battery management and energy storage — Stabilizing supply rails and absorbing transient currents in high-temperature environments.
• Industrial power systems — Bulk capacitance for control, drive, and auxiliary power circuits operating in elevated ambient temperatures.

Unique Advantages

• High-temperature reliability: Endurance of 4000 hours at 135 °C supports long-term operation in thermally challenging environments.
• Predictable high-frequency behavior: 20 mΩ ESR at 100 kHz and 0.14 tan δ at 120 Hz deliver low-loss performance for switching and high-speed converter applications.
• Strong ripple handling: Dual-frequency ripple specs (300 mA at 120 Hz, 2.0 A at 100 kHz) reduce thermal stress and extend service life under AC loading.
• Compact SMD can: φ10 × 10 mm footprint offers substantial capacitance in a board-friendly surface-mount package for automated assembly.
• Industry qualification: AEC‑Q200 rating and RoHS compliance provide design confidence for regulated and automotive programs.
