UPM1J681MHD

The UPM1J681MHD is a radial-lead aluminum electrolytic capacitor from Nichicon's UPM series. It provides 680 µF capacitance at a 63 V rating in a compact φ16 × 30.5 mm can with 7.5 mm lead spacing, designed for demanding thermal and electrical environments.

With AEC-Q200 qualification, a wide operating temperature range of −55 °C to +105 °C and a 5000-hour load life at 105 °C, this component targets automotive-grade applications where low impedance, stable performance and long-term reliability are required.

Key Features

• Capacitance & Voltage: 680 µF rated capacitance at 63 V with ±20% tolerance (120 Hz, 20 °C), suitable for energy storage and decoupling in high-voltage circuits.
• Low Impedance: Rated impedance of 32 mΩ helps minimize voltage drop under ripple and transient conditions.
• Ripple Handling: Specified ripple current of 1.156 A at 120 Hz and 1.7 A at 200 kHz supports continuous ripple loading across low and high frequencies.
• Loss Characteristics: Tangent of loss angle (tan δ) of 0.08 at the rated voltage, supporting predictable AC behavior at 120 Hz.
• Leakage Current: Specified leakage current of 1285.2 µA, allowing designers to budget for standby and leakage behavior in system power budgets.
• Thermal Endurance & Reliability: 5000-hour rated life at 105 °C and operating range from −55 °C to +105 °C, providing long-term stability in elevated-temperature environments.
• Package & Mounting: Radial-lead can (φ16 × 30.5 mm) with 7.5 mm lead spacing for through-hole assembly; polarized construction for correct polarity installation.
• Qualification & Compliance: AEC-Q200 qualified and RoHS compliant, aligning with automotive reliability and environmental requirements.

Typical Applications

• Automotive electronic modules: Use in automotive modules where AEC-Q200 qualification, −55 °C to +105 °C operating range and 5000-hour life at 105 °C are required.
• Power electronics assemblies: Suitable for power-supply and energy-storage roles in systems that require 63 V rating and high ripple-current capability.
• Control and ECU environments: Applicable to electronic control units and control modules that demand stable capacitance and low impedance over temperature and time.

Unique Advantages

• Automotive-grade qualification: AEC-Q200 rating provides documented suitability for automotive electronic applications.
• Long-term thermal reliability: 5000 hours at 105 °C supports prolonged high-temperature operation and predictable end-of-life behavior.
• Effective ripple management: Low impedance (32 mΩ) together with specified ripple currents at 120 Hz and 200 kHz helps reduce voltage ripple in power systems.
• Compact through-hole form factor: φ16 × 30.5 mm can with 7.5 mm lead spacing fits standard radial lead assemblies while delivering 680 µF at 63 V.
• Clear electrical parameters: Tangent of loss angle (tan δ = 0.08) and quantified leakage current (1285.2 µA) allow accurate system-level budgeting for losses and standby currents.
• Environmental compliance: RoHS compliance supports regulatory and end-product environmental requirements.
