GYF1E681MCW1GS

The GYF1E681MCW1GS is a conductive polymer hybrid aluminum electrolytic capacitor in a surface-mount radial can package, designed for high-reliability applications. It provides 680 µF capacitance at 25 V with low equivalent series resistance and high ripple-handling capability.

Targeted at automotive and other demanding markets, this capacitor combines long endurance, wide operating temperature (-55 °C to 125 °C), and vibration resistance to support power smoothing and high-ripple circuits where durability and stable performance are required.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance with a ±20% tolerance at a rated voltage of 25 V, suitable for bulk decoupling and energy storage in power rails.
• Low ESR — ESR of 16 mΩ measured at 20 °C and 100 kHz, minimizing losses and improving transient response in high-frequency circuits.
• High Ripple Current Capacity — Supports low-frequency ripple current of 525 mA (120 Hz) and high-frequency ripple current of 3.5 A (100 kHz), enabling robust performance under dynamic load conditions.
• Long Endurance at Elevated Temperature — Rated 4000 hours life at 125 °C, maintaining capacitance, tan δ, and ESR within specified endurance limits after the test period.
• Wide Operating Temperature Range — Specified for continuous operation from −55 °C to 125 °C to meet harsh-environment requirements.
• Leakage Current — Specified leakage current of 170 µA for predictable standby behavior in power-sensitive designs.
• Automotive-Grade Reliability — AEC-Q200 rating cited for series-level qualification, supporting use in automotive electronics requiring component-level reliability.
• Compact Surface-Mount Can — φ10 × 12.5 L (L: 1.25 cm × D: 1.0 cm) radial can SMD package with embossed carrier taping for automated assembly and vibration resistance.

Typical Applications

• Battery Management Systems (BMS) — Handles high ripple and provides low-impedance bulk capacitance to stabilize battery and power-management circuits.
• Automotive Power Supplies — Smooths DC rails and absorbs transient loads in automotive electronic modules operating across a wide temperature range.
• DC–DC Converters and Voltage Regulation — Supports input/output filtering where low ESR and high ripple current capability improve efficiency and transient performance.

Unique Advantages

• High ripple tolerance: 3.5 A at 100 kHz and 525 mA at 120 Hz allow reliable operation in circuits with substantial AC components on DC rails.
• Low-loss operation: 16 mΩ ESR at 100 kHz reduces heat generation and improves converter efficiency under high-frequency switching.
• Extended high-temperature life: 4000 hours at 125 °C provides design margin for long-term deployment in elevated-temperature environments.
• Automotive-focused qualification: Series AEC-Q200 rating supports use in vehicle electronics and other applications requiring automotive-level reliability.
• Compact SMD form factor: Radial can SMD packaging with embossed carrier taping enables automated assembly and helps meet board-space constraints.
• Predictable leakage behavior: Specified leakage current of 170 µA supports power budgeting and standby leakage planning.
