UPM1J680MPD

The UPM1J680MPD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UPM series. It delivers 68 µF capacitance at a 63 V rating in a compact radial-can package intended for demanding electronic power applications.

Designed for low impedance and high reliability, this part is AEC-Q200 qualified and RoHS compliant, with a wide operating temperature range and rated life at elevated temperature—making it suitable for automotive and other electronics systems requiring stable bulk capacitance and ripple handling.

Key Features

• Electrical performance — 68 µF nominal capacitance with a 63 V rated voltage and ±20% tolerance at 120 Hz, 20 °C.
• Low impedance and loss — Specified impedance 170 mΩ and a tan δ of 0.08 (max) at the rated voltage and test conditions provides reduced AC loss in filtering and smoothing applications.
• Ripple-current capability — Rated ripple currents of 160.7 mA at 120 Hz and 315 mA at 200 kHz for effective handling of AC ripple in power rails.
• Leakage current — Measured leakage current of 128.52 µA after rated-voltage application, suitable for power electronics where defined leakage is required.
• Reliability and life — Rated for 3000 hours at 105 °C (endurance specified for smaller case sizes), with characteristic stability requirements after endurance and shelf-life testing according to the series datasheet.
• Operating temperature — Wide operating range from −55 °C to +105 °C to support harsh-environment deployments.
• Package and mounting — Radial lead, can-style package with nominal diameter φ8 mm and compact footprint (size 1.5 × 0.8 cm) and 3.5 mm lead spacing for through-hole assemblies.
• Standards and compliance — AEC-Q200 qualified and RoHS compliant for regulated and automotive markets.

Typical Applications

• Automotive power electronics — Bulk smoothing and decoupling on automotive power rails where AEC-Q200 qualification and operation to 105 °C are required.
• On-board power supplies — Filtering and energy storage in DC power modules that require 63 V-rated capacitance with specified ripple-current handling.
• General DC filtering — Decoupling and ripple suppression in embedded power subsystems that benefit from low impedance and defined leakage characteristics.

Unique Advantages

• AEC-Q200 qualification: Provides an added level of assurance for automotive and similarly demanding applications that call for component-level reliability.
• Designed for elevated-temperature endurance: 3000-hour rating at 105 °C supports long-term stability in hot operating environments.
• Low impedance and low loss: 170 mΩ impedance and tan δ 0.08 minimize AC losses and improve filtering effectiveness.
• Measurable ripple performance: Specified ripple current at both low and high test frequencies (120 Hz and 200 kHz) allows predictable thermal and electrical behavior in converter and supply designs.
• Compact radial-can footprint: φ8 mm diameter and 3.5 mm lead spacing enable dense through-hole layouts and straightforward assembly.
• Regulatory compliance: RoHS conformity supports integration into regulated products and markets.
