GWC1H680MCX1GS

The GWC1H680MCX1GS is a surface-mount conductive polymer hybrid aluminum electrolytic capacitor designed for high-reliability, high-temperature applications. As a chip-type SMD capacitor, it delivers low impedance and high ripple-current capability in a compact φ8 × 10 mm can-style package.

Targeted for automotive and other demanding environments, this capacitor combines a 68 µF nominal capacitance at 50 V with low ESR and a long rated life of 4000 hours at 135°C to support power conversion, filtering and decoupling in thermally and electrically stressful systems.

Key Features

• Capacitance and Voltage — 68 µF nominal capacitance rated for 50 V operation, with a tolerance of ±20% at 20°C, 120 Hz.
• Low Impedance / High Ripple Handling — ESR of 24 mΩ measured at 100 kHz (20°C) and high-frequency ripple current of 2.7 A at 100 kHz, enabling robust performance in high-ripple power stages; low-frequency ripple current is 405 mA at 120 Hz.
• High Temperature Endurance — Rated operating temperature range from −55°C to +135°C with endurance specified as 4000 hours at 135°C under rated conditions.
• Leakage & Loss Characteristics — Typical leakage current of 34 µA and tan δ (DF) 0.10 at 20°C, 120 Hz for the 50 V rating.
• Automotive-Grade Reliability — AEC-Q200 qualified for use in automotive electronics; designed for long life and stability under thermal and electrical stress.
• SMD Packaging and Assembly — Radial can-style SMD package (φ8 × 10 mm) with embossed carrier taping for automated surface-mount assembly; recommended land size 8.3 × 8.3 mm.
• Compliance — RoHS-compliant.

Typical Applications

• Automotive Power Electronics — Suitable for power modules and electronic control units where high-temperature endurance and high ripple current capability are required.
• DC–DC Converters and Power Regulation — Use for bulk filtering and output decoupling in converter designs that demand low ESR and stable performance at elevated temperatures.
• High-Reliability Embedded Systems — Fits compact boards that require long-life capacitors capable of sustaining performance up to 135°C.

Unique Advantages

• Short-term thermal robustness: Rated for operation to 135°C with a 4000-hour endurance rating, supporting sustained use in hot environments.
• Enhanced ripple handling: Low ESR (24 mΩ @100 kHz) and high-frequency ripple capability (2.7 A) reduce voltage ripple and thermal stress in power circuits.
• Compact SMD form factor: φ8 × 10 mm can-style SMD package and embossed carrier taping streamline automated assembly while conserving board area.
• Automotive qualification: AEC-Q200 rating provides an added level of design assurance for automotive electronics applications.
• Measured, predictable leakage and loss: Specified leakage current (34 µA) and tan δ (0.10 at 50 V, 120 Hz) enable predictable behavior in precision and power applications.
• Regulatory compliance: RoHS-compliant for global conformity in commercial and industrial products.
