GYC1V271MCW1GS

The GYC1V271MCW1GS is a surface-mount conductive polymer hybrid aluminum electrolytic capacitor designed for high-temperature, high-reliability power applications. It delivers 270 µF at 35 V with low ESR and elevated ripple-current capability in a compact φ10 × 10 mm SMD can.

Engineered for automotive and demanding industrial environments, this AEC-Q200 qualified device offers long life at 135°C and features targeted electrical characteristics for power-supply filtering, decoupling, and high-frequency switching circuits.

Key Features

• Capacitance & Voltage — 270 µF nominal capacitance with ±20% tolerance at 120 Hz, rated for 35 V operation.
• Low Loss / Low ESR — tan δ of 0.12 (120 Hz, 20°C) and ESR of 20 mΩ measured at 100 kHz, 20°C, supporting efficient energy handling in switching applications.
• High Ripple Current Capability — 300 mA at 120 Hz (low frequency) and 2.0 A at 100 kHz (high frequency) for robust performance with both line-frequency and high-frequency ripple.
• High-Temperature Endurance — Rated for continuous operation from −55°C to 135°C with a life rating of 4000 hours at 135°C.
• Leakage Current — Specified leakage current of 94.5 µA (after 2 minutes at rated voltage, 20°C), consistent with the capacitor’s CV-based specification.
• Automotive-Grade Reliability — AEC-Q200 qualified and vibration resistant for use in automotive electronic modules and other demanding environments.
• Surface-Mount Packaging — Compact radial can SMD package (φ10 × 10 mm) supplied in embossed carrier taping for automated assembly.
• Regulatory Compliance — RoHS compliant.

Typical Applications

• Automotive Power Electronics — Bulk filtering and decoupling in ECUs, DC–DC converters and power modules where high temperature endurance and AEC-Q200 qualification are required.
• Switch-Mode Power Supplies — Output filtering and high-frequency ripple handling in DC–DC converters and point-of-load regulators.
• Industrial Power Systems — Energy buffering and smoothing in high-temperature industrial control and power distribution units.
• Infotainment & Telematics — Stable decoupling in vehicle electronics subject to vibration and elevated operating temperatures.

Unique Advantages

• Low ESR for improved efficiency: 20 mΩ ESR at 100 kHz reduces conduction losses and supports tighter voltage regulation under load.
• High ripple tolerance across frequencies: Rated ripple currents of 300 mA (120 Hz) and 2.0 A (100 kHz) accommodate both line-frequency and switching ripple profiles.
• Designed for high-temperature durability: 4000 hours life at 135°C enables reliable operation in elevated-temperature environments.
• Automotive-ready qualification: AEC-Q200 rating and vibration resistance provide assurance for vehicle electronics and similar demanding applications.
• Compact SMD can package: φ10 × 10 mm footprint in embossed carrier taping simplifies automated assembly while delivering high capacitance density.
• Predictable leakage behavior: Leakage current specified as 94.5 µA (2 minutes at rated voltage, 20°C) for design-level planning.
