UPM1J820MPD

The UPM1J820MPD is a radial-lead aluminum electrolytic capacitor from Nichicon's UPM series designed for low-impedance, high-reliability power applications. It delivers 82 µF at a 63 V rating in a compact φ8 × 20 mm can with 3.5 mm lead spacing.

Engineered for demanding environments, this polarized capacitor combines a wide operating temperature range (−55°C to +105°C), AEC-Q200 qualification, and a rated endurance of 3000 hours at 105°C for small case sizes—making it suitable for robust automotive power systems and other applications that require reliable bulk capacitance and ripple handling.

Key Features

• Capacitance & Voltage — 82 µF nominal capacitance with a 63 V rated voltage and ±20% tolerance (120 Hz, 20°C).
• Low Loss — tan δ of 0.08 (max.) at the rated voltage, supporting efficient energy storage with minimal dissipation.
• Low Impedance — specified impedance of 150 mΩ to help reduce voltage ripple under load.
• Leakage Current — typical leakage current listed as 154.98 µA, consistent with electrolytic performance expectations.
• Ripple Current Capability — 200.2 mA at 120 Hz and 385 mA at 200 kHz, enabling effective smoothing and decoupling across low and high frequency ranges.
• High Reliability & Lifetime — endurance specified as 3000 hours at 105°C for smaller case sizes; series notes also reference 5000 hours at 105°C for larger sizes where applicable.
• Automotive-Grade Qualification — AEC-Q200 qualified, supporting use in automotive electronic designs.
• Compact Radial Package — φ8 × 20 mm can (L: 2.0 cm × D: 0.8 cm) with 3.5 mm lead spacing and radial lead mounting for through-hole assemblies; lead diameter for φ8 units is 0.6 mm per series specifications.
• Wide Temperature Range — Rated for operation from −55°C to +105°C.
• RoHS Compliant — Meets RoHS material requirements.

Typical Applications

• Automotive power systems — Bulk smoothing and decoupling in vehicle power electronics, leveraging the capacitor's low impedance, rated ripple current, and AEC-Q200 qualification.
• Electronic control modules — Local energy storage and transient suppression in modules that require stable capacitance across −55°C to +105°C.
• Power conditioning — Filtering and ripple attenuation in DC power supplies where compact radial-can packaging and high ripple capability are required.

Unique Advantages

• Automotive-qualified reliability: AEC-Q200 qualification and 3000-hour endurance at 105°C for small case sizes provide documented suitability for vehicle electronics.
• Compact footprint: φ8 × 20 mm radial can offers substantial capacitance in a small through-hole package for space-constrained board designs.
• High ripple tolerance: Measured ripple currents at both low and high frequencies (200.2 mA at 120 Hz, 385 mA at 200 kHz) support effective smoothing across a range of switching environments.
• Low electrical loss: Low tan δ (0.08) and 150 mΩ impedance reduce heat generation and improve AC performance in power circuits.
• Wide temperature operation: −55°C to +105°C rating maintains capacitance stability across harsh thermal conditions.
• Regulatory compliance: RoHS compliance supports use in regulated manufacturing environments.
