GYB1H680MCQ1GS

The GYB1H680MCQ1GS is a conductive polymer hybrid aluminum electrolytic capacitor in a surface-mount can package, offering 68 µF capacitance at a 50 V rating. It is designed for applications requiring low ESR, high ripple current handling, and long-term stability across a wide temperature range.

Targeted at automotive and high-reliability power electronics, this capacitor combines low impedance (30 mΩ at 100 kHz) and a 10000-hour endurance at 105°C to support robust power filtering and decoupling in demanding environments.

Key Features

• Capacitance & Voltage — 68 µF nominal capacitance with a rated voltage of 50 V and ±20% tolerance, suitable for mid-voltage power rails.
• Low ESR & Loss — ESR of 30 mΩ measured at 100 kHz and 20°C, and tan δ of 0.10 at 20°C, 120 Hz (50 V), enabling efficient high-frequency ripple performance.
• High Ripple Current Capability — Low-frequency ripple current of 270 mA at 120 Hz and high-frequency ripple current of 1.8 A at 100 kHz for effective smoothing under dynamic loads.
• Long Endurance — Rated life of 10000 hours at 105°C under specified bias and ripple conditions, with defined limits for capacitance change, tan δ and ESR after endurance testing.
• Temperature Range & Stability — Operates from –55°C to 105°C with impedance stability defined across low temperatures (Z(–25°C)/Z(+20°C) ≤ 2, Z(–55°C)/Z(+20°C) ≤ 2.5 at 100 kHz).
• Package & Mounting — Surface-mount radial can (φ8 × 10L) in embossed carrier taping for automated PCB assembly; recommended PCB land size 8.3 × 8.3 mm.
• Automotive-Grade Qualification — AEC-Q200 rating and RoHS compliance for use in regulated environments.

Typical Applications

• Automotive Power Electronics — Bulk decoupling and smoothing on 12 V/48 V vehicle power rails where AEC-Q200 qualification and long life at 105°C are required.
• In-vehicle ECUs and Control Modules — Local energy storage and transient suppression for electronic control units that demand low ESR and stable performance across –55°C to 105°C.
• High-frequency Power Filtering — Decoupling for converters and regulators that generate high-frequency ripple, leveraging the 1.8 A ripple capability at 100 kHz and low ESR.

Unique Advantages

• Low impedance for high-frequency stability: 30 mΩ ESR at 100 kHz reduces voltage ripple and improves regulator stability in high-frequency circuits.
• High ripple tolerance: Combined low- and high-frequency ripple ratings (270 mA @120 Hz, 1.8 A @100 kHz) allow a single part to address a wide range of ripple environments.
• Designed for long-term high-temperature operation: 10000-hour life at 105°C provides predictable aging and service life in thermally demanding applications.
• Automotive qualification and compliance: AEC-Q200 rating and RoHS compliance support designs that require recognized reliability and environmental compliance.
• Compact SMD can format: φ8 × 10L surface-mount can with embossed carrier taping supports automated assembly and space-efficient PCB layouts.
