UHD0J561MPD

The UHD0J561MPD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UHD series, featuring a compact φ8×11.5 mm can and a 3.5 mm lead spacing. It is a general-purpose polarized capacitor designed for applications that require significant ripple-current handling and low impedance at higher frequencies.

Key value propositions include high ripple-current capability, low-loss performance at 120 Hz, a wide operating temperature range from −40°C to 105°C, and a rated life of 3000 hours at 105°C under rated conditions.

Key Features

• Capacitance & Voltage: 560 µF nominal capacitance with a rated voltage of 6.3 V and tolerance of −20% to +20% (measured at 120 Hz, 20°C).
• Low Dissipation Factor: tanδ (DF) of 0.22 at 20°C, 120 Hz (rated 6.3 V), supporting efficient energy handling with controlled losses.
• High Ripple Current Capacity: Low-frequency ripple current of 570 mA (120 Hz) and high-frequency ripple current of 760 mA (100 kHz), matched to high-ripple environments.
• Leakage Current: Specified leakage current of 35.28 µA after standard application conditions.
• Temperature & Endurance: Operates from −40°C to 105°C with an endurance rating of 3000 hours at 105°C under DC bias plus rated ripple current.
• Compact Radial Package: φ8 × 11.5 mm can (L: 1.15 cm × D: 0.8 cm) with 3.5 mm lead spacing (±0.5 mm), supplied in bulk or bag packing.
• RoHS Compliant: Conforms to RoHS directive requirements as noted in product documentation.

Typical Applications

• General-purpose electronic circuits: Provides bulk capacitance and filtering where a 560 µF, 6.3 V polarized capacitor is required.
• High-ripple environments: Suitable for circuits subject to significant AC ripple thanks to rated ripple currents of 570 mA (120 Hz) and 760 mA (100 kHz).
• Compact radial through-hole assemblies: Designed for space-constrained PCB layouts using radial-lead mounting with a φ8 can and 3.5 mm lead spacing.

Unique Advantages

• High ripple tolerance: Explicit ripple-current ratings at both low and high frequencies reduce the need to derate for ripple stress in many designs.
• Low-loss performance at 120 Hz: A specified tanδ of 0.22 at 20°C and 120 Hz helps minimize power dissipation in filter and smoothing applications.
• Compact footprint: φ8×11.5 mm can and tight lead spacing enable smaller board layouts without sacrificing capacitance.
• Wide operating range and endurance: −40°C to 105°C operating range and 3000 hours life at 105°C provide predictable long-term behavior under elevated temperature and bias conditions.
• Measured leakage current: A defined leakage current figure (35.28 µA) allows designers to budget standby losses precisely.
• RoHS compliance: Meets environmental directive requirements for restricted substances as documented in product materials.
