UPJ1K6R8MDD

The UPJ1K6R8MDD is a miniature, high-reliability aluminum electrolytic capacitor in Nichicon's UPJ series. It is a radial-lead, polarized capacitor designed for general-purpose use and for applications where low impedance and compact size are required.

With an 80 V rated voltage, 6.8 µF capacitance and a wide operating temperature range, this part suits compact power assemblies and switching power supply applications that require reliable filtering and decoupling on higher-voltage rails.

Key Features

• Capacitance & Rated Voltage — 6.8 µF nominal capacitance with an 80 V rated voltage and tolerance of ±20% (–20% to +20%).
• Low Impedance Series — Part of the UPJ series, which is specified for low impedance performance suitable for switching power supply applications.
• Ripple Current Performance — Low-frequency ripple current 17 mA at 120 Hz and high-frequency ripple current 34 mA at 200 kHz, enabling effective ripple handling across frequencies.
• Dissipation & Leakage — Dissipation factor (tan δ) 0.08 measured at 20°C, 120 Hz and 80 V; specified leakage current 16.32 µA.
• Temperature & Endurance — Operating temperature range from –55°C to +105°C with a rated life/endurance of 2000 hours at 105°C.
• Compact Radial Package — Cylindrical can, size φ5 × 11 mm (L: 1.1 × D: 0.5 cm) with 2.0 mm lead spacing (±0.5 mm).
• Mounting & Packaging — Polarized radial-lead mounting; available in bulk (no terminal forming) or bag packing.
• RoHS Compliant — Conforms to RoHS requirements.

Typical Applications

• Switching Power Supplies — Low impedance characteristics and specified ripple currents make this capacitor suitable for filtering and decoupling in switch-mode power circuits.
• High‑Voltage PCB Power Rails — 80 V rating and compact footprint support decoupling on higher-voltage rails in compact assemblies.
• General‑Purpose Power Filtering — Provides reliable energy storage and ripple reduction in a range of general-purpose electronic equipment.

Unique Advantages

• High-voltage capability: 80 V rating allows use on higher-voltage rails while maintaining a small package footprint.
• Compact footprint: φ5 × 11 mm can size and 2 mm lead spacing help conserve PCB area in dense designs.
• Measured low dissipation and leakage: tan δ of 0.08 and leakage current of 16.32 µA support stable performance in filtering applications.
• Wide thermal range and defined endurance: –55°C to +105°C operation with 2000 hours endurance at 105°C provides predictable life under elevated temperature stress.
• Designed for switching applications: UPJ series low-impedance characteristics improve ripple suppression in power conversion circuits.
• RoHS compliant: Suitable for lead‑free manufacturing environments.
