UPJ1H6R8MDD

The UPJ1H6R8MDD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UPJ series, designed for low-impedance performance in power applications. It provides 6.8 µF capacitance at a 50 V rating in a compact φ5 × 11 mm can with 2 mm lead spacing.

This part is suited for general-purpose power filtering and switching power supply circuits where compact size, low leakage and defined ripple handling across low and high frequencies are required.

Key Features

• Capacitance & Tolerance — 6.8 µF with tolerance of -20% to +20% (specified at 120 Hz, 20°C).
• Rated Voltage — 50 V DC rating for mid-voltage power rails and filtering tasks.
• Low‑impedance design — UPJ series specification targets low impedance behavior suitable for switching power supplies; specified tanδ (DF) = 0.10 at 20°C, 120 Hz for this rated voltage.
• Ripple performance — Defined ripple capability: 22.5 mA at 120 Hz (low frequency) and 45 mA at 200 kHz (high frequency), enabling predictable performance under AC ripple loads.
• Low leakage — Leakage current specified at 10.2 µA, supporting stable bias conditions in DC circuits.
• Temperature & Endurance — Operating range -55°C to +105°C with rated life/endurance specified as 2000 hours at 105°C for this part.
• Compact radial package — Can-style radial lead package with dimensions φ5 × 11 mm and 2 mm lead spacing (±0.5 mm), available in bulk/bag packing.
• RoHS compliant — Meets RoHS directive requirements as indicated for the UPJ series.

Typical Applications

• Switching power supplies — Low-impedance behavior and defined tanδ make this part suitable for filtering and smoothing in switch-mode power stages.
• Power filtering and decoupling — 6.8 µF capacitance and low leakage support local decoupling on mid-voltage rails and PCB power planes.
• Compact power modules — Small φ5 × 11 mm can and radial leads fit space-constrained power assemblies and modules.

Unique Advantages

• Predictable AC performance — Specified low- and high-frequency ripple currents (22.5 mA at 120 Hz, 45 mA at 200 kHz) allow designers to size capacitors against measured ripple loads.
• Stable leakage characteristics — 10.2 µA leakage current supports stable biasing and predictable standby behavior in DC circuits.
• Compact footprint — φ5 × 11 mm can and 2 mm lead spacing reduce board area while keeping a standard radial form factor for through-hole assembly.
• Wide operating temperature — Specified for -55°C to +105°C operation, enabling use across a broad range of thermal environments.
• RoHS compliance — Meets regulatory requirements for restricted substances, simplifying regulatory management for products incorporating the capacitor.
