UPM1C681MHD6

The UPM1C681MHD6 is a radial-lead aluminum electrolytic capacitor from Nichicon’s UPM series, offering 680 µF capacitance at a 16 V rating. It is engineered for applications that demand low impedance, reliable long-term operation at elevated temperatures, and compact packaging.

Targeted for automotive environments, this AEC-Q200 qualified component delivers specified performance across a wide temperature range and a long rated lifetime for demanding power conditioning and decoupling tasks.

Key Features

• Capacitance & Voltage: 680 µF nominal capacitance with a 16 V rated voltage and ±20% tolerance, suitable for mid-voltage power rails.
• Low Impedance: Rated impedance of 70 mΩ provides effective decoupling and reduced voltage drop under dynamic loads.
• High Ripple Current Capability: Supports 557.6 mA at 120 Hz and 820 mA at 200 kHz, enabling handling of both low- and high-frequency ripple currents.
• High Temperature Endurance: Designed for 5000 hours of load life at +105°C, supporting long-term stability in elevated-temperature environments.
• Automotive Qualification: AEC-Q200 rated, making it suitable for qualified automotive system use cases where that standard is required.
• Compact Radial Can Package: φ12.5 × 15 mm can with 5 mm lead spacing and radial lead mounting for through-hole assembly and straightforward mechanical retention.
• Leakage and Loss Characteristics: Specified tan δ of 0.16 and measured leakage current of 326.4 µA, providing quantifiable loss and leakage behavior for design margining.
• Compliance: RoHS compliant.

Typical Applications

• Automotive power electronics — Bulk energy storage and smoothing on 16 V rails where low impedance and long-life performance at up to +105°C are required.
• Control modules and ECUs — Power rail decoupling and filtering for electronic control units that require AEC-Q200 qualified components and extended endurance.
• Infotainment and telematics power supplies — Decoupling and ripple suppression for circuits seeing both low- and high-frequency ripple currents (specified at 120 Hz and 200 kHz).
• On-board filtering — General-purpose bulk capacitance and smoothing in automotive assemblies where a compact radial can with 5 mm lead spacing is preferred.

Unique Advantages

• Verified high-temperature lifetime: 5000 hours at +105°C provides designers with a quantifiable endurance metric for heated environments.
• AEC-Q200 qualification: Explicit automotive rating simplifies component selection for applications requiring automotive-grade parts.
• Strong ripple handling across frequencies: Dual ripple current specifications (557.6 mA at 120 Hz, 820 mA at 200 kHz) enable designers to address a range of switching and alternator-induced ripple.
• Low impedance for tight regulation: 70 mΩ impedance helps maintain voltage stability under transient loads and reduces losses in power delivery networks.
• Compact, through-hole form factor: φ12.5 × 15 mm radial can with 5 mm lead spacing for easy placement in legacy and mechanically robust PCB layouts.
• Measurable leakage and dissipation values: Specified leakage current (326.4 µA) and tan δ (0.16) allow accurate margining during power budget and thermal assessments.
