GYE1C391MCW1GS

The GYE1C391MCW1GS is a conductive polymer hybrid aluminum electrolytic capacitor in a compact surface‑mount can package. It delivers 390 µF capacitance at a 16 V rating with a chip‑type construction optimized for high ripple currents and elevated operating temperatures.

Designed for high‑reliability applications, this part combines low equivalent series resistance, long life at high temperature, and AEC‑Q200 qualification, making it suitable for demanding automotive and industrial electronics environments.

Key Features

• Capacitance & Voltage — 390 µF nominal capacitance with ±20% tolerance at 20°C (120 Hz) and a rated voltage of 16 V.
• Low Impedance / ESR — ESR specified at 25 mΩ (measured at 20°C, 100 kHz), providing low impedance at high frequency.
• High Ripple Current — Rated low‑frequency ripple current 300 mA (120 Hz) and high‑frequency ripple current 2.0 A (100 kHz).
• High‑Temperature Endurance — Long life: 4000 hours at 125°C under DC bias plus rated ripple current; operating temperature range −55°C to +125°C.
• Reliability & Qualification — AEC‑Q200 qualified and RoHS compliant, suitable for applications requiring industry reliability standards.
• Package & Assembly — Surface‑mount radial can (φ8 × 10 mm) with embossed carrier taping for automated placement; vibration resistant.
• Leakage & Loss Characteristics — Leakage current specified at 62.4 µA and tan δ (DF) of 0.16 at 20°C, 120 Hz for the 16 V rating.

Typical Applications

• Automotive Electronics — For electronic control modules and in‑vehicle power circuits that require AEC‑Q200 qualified passive components and long life at elevated temperatures.
• Power Supply Filtering & Decoupling — Low ESR and high ripple‑current capability make this capacitor suitable for smoothing and high‑frequency decoupling in DC‑DC converters and power rails.
• Industrial Power Electronics — Designed for systems that operate at elevated temperatures up to 125°C and require sustained performance over long endurance periods.
• Vibration‑Prone Assemblies — Vibration resistant construction supports use in equipment subject to mechanical stress.

Unique Advantages

• Conductive polymer hybrid construction — Combines polymer and aluminum electrolytic characteristics for higher capacitance density in an SMD can.
• Low high‑frequency impedance — ESR of 25 mΩ at 100 kHz reduces impedance where high‑frequency ripple is present.
• High ripple handling — Rated for 2.0 A at 100 kHz and 300 mA at 120 Hz to support circuits with substantial AC stress.
• Extended high‑temperature life — 4000 hours endurance at 125°C under rated conditions for long‑term stability in hot environments.
• AEC‑Q200 qualified and RoHS compliant — Meets specified automotive reliability standard and environmental compliance.
• Surface‑mount, tape‑and‑reel friendly — Embossed carrier taping enables automated assembly and repeatable placement.
