GYF1V391MCW1GS

The GYF1V391MCW1GS from Nichicon is a conductive polymer hybrid aluminum electrolytic capacitor in a surface-mount can package. It delivers 390 µF capacitance at a 35 V rating with low ESR and high ripple-current capability for demanding environments.

Engineered for high-temperature and high-ripple applications, the GYF1 series is AEC-Q200 qualified and RoHS compliant, offering a long endurance (4000 hours at 125 °C) and vibration-resistant construction suitable for automotive and other robust electronic systems such as battery management subsystems.

Key Features

• Capacitance and Voltage — 390 µF nominal capacitance with ±20% tolerance at 20 °C, rated for 35 V operation.
• Low Loss (tan δ) — tanδ of 0.12 measured at 20 °C, 120 Hz, enabling predictable ripple performance.
• Very Low ESR — ESR of 20 mΩ at 20 °C, 100 kHz for reduced dissipation and improved high-frequency performance.
• High Ripple Current Handling — Low-frequency ripple current 420 mA (120 Hz) and high-frequency ripple current 2.8 A (100 kHz) to support high-stress power circuits.
• Long Endurance at Elevated Temperature — Rated endurance of 4000 hours at 125 °C with specified limits for capacitance change, tanδ and ESR after test.
• Wide Temperature Range — Operating range from −55 °C to +125 °C for use in thermally challenging environments.
• Automotive Qualification and Compliance — AEC-Q200 qualified and RoHS compliant, supporting automotive and high-reliability programs.
• Surface-Mount, Assembly-Friendly Packaging — SMD can (φ10 × 10L) with embossed carrier taping and vibration-resistant design for automated placement.

Typical Applications

• Automotive Electronics — Bulk capacitance and high ripple capability for electronic control modules and power conditioning in automotive environments.
• Battery Management Systems (BMS) — High ripple current and low ESR characteristics suited to smoothing and decoupling in BMS applications.
• Power Supply Filtering — Bulk and decoupling use where low ESR and high-frequency ripple handling improve regulator stability and transient response.
• High-Temperature Electronics — Elevated endurance at 125 °C for electronics that must tolerate sustained high operating temperatures.

Unique Advantages

• High ripple-current capability: Supports up to 2.8 A at 100 kHz and 420 mA at 120 Hz, reducing thermal stress in power stages.
• Low ESR (20 mΩ): Minimizes power loss and improves efficiency in high-frequency circuits.
• Extended high-temperature life: 4000 hours at 125 °C provides predictable long-term performance in harsh environments.
• AEC-Q200 qualification: Meets automotive-grade reliability requirements for designs targeting vehicle systems.
• Compact SMD can with tape packaging: φ10 × 10L SMD can and embossed carrier taping simplify automated assembly and save board space compared with through-hole alternatives.
• RoHS compliant and mass-production available: Documented compliance and production status for volume designs.
