UVR1E223MRD

The UVR1E223MRD is a Nichicon UVR-series miniature aluminum electrolytic capacitor in a radial-lead can, delivering 22,000 µF of polarized capacitance at a 25 V rating. It is designed for general-purpose applications and entertainment electronics where bulk energy storage and ripple smoothing are required.

Key electrical characteristics include high ripple-current capability at both low and high frequencies, a wide operating temperature range of −40 °C to +85 °C, and a rated endurance of 2000 hours at 85 °C. The part is RoHS compliant and supplied in bulk or bag packing.

Key Features

• Capacitance and Tolerance — 22,000 µF nominal capacitance with tolerance −20% to +20% at 120 Hz, 20 °C, providing substantial bulk charge storage for smoothing and decoupling.
• Rated Voltage — 25 V DC rating suitable for many low-voltage power supply rails and energy-storage applications.
• Ripple Current Performance — Low-frequency ripple current 4.5 A at 120 Hz and high-frequency ripple current 5.175 A at 10 kHz, supporting effective AC ripple handling across common power frequencies.
• Loss Characteristics — Tangent of loss angle (tan δ) of 0.58 measured at 20 °C, 120 Hz, for assessing ESR-related losses in filter and smoothing applications.
• Leakage Current — Specified leakage current of 16,500 µA, defined under rated-voltage conditions for initial screening and design margining.
• Package and Mounting — Radial-lead can with φ25 × 50 mm dimensions, lead spacing 12.5 mm (±0.5 mm), and polarized orientation for through-hole assemblies.
• Temperature and Endurance — Operating range −40 °C to +85 °C with a rated life of 2000 hours at 85 °C, providing predictable aging characteristics for thermal designs.
• Environmental Compliance — RoHS compliant.

Typical Applications

• General-purpose power supplies — Bulk smoothing and energy storage on low-voltage rails to reduce ripple and support transient loads.
• Entertainment electronics — Bulk decoupling and filtering in consumer AV equipment where UVR series components are specified.
• Through-hole PCB assemblies — Radial-lead packaging and 12.5 mm lead spacing for reliable mounting in conventional board-level power sections.

Unique Advantages

• Large bulk capacitance: 22,000 µF delivers significant energy reserve for smoothing and hold-up in compact footprints.
• Dual-frequency ripple capability: Rated ripple currents for both 120 Hz (4.5 A) and 10 kHz (5.175 A) enable designers to quantify performance across power-conversion harmonics.
• Design-ready mechanical form: φ25 × 50 mm can and defined 12.5 mm lead spacing (±0.5 mm) simplify mechanical integration and PCB layout for through-hole designs.
• Predictable thermal endurance: 2000 hours at 85 °C rating and −40 °C to +85 °C operating range help in specifying lifetime and thermal margins.
• Clear electrical parameters: Published tan δ and leakage current values (0.58 at 20 °C, 120 Hz; 16,500 µA) allow straightforward ESR and leakage budgeting in designs.
• RoHS compliance: Meets environmental directive requirements for lead-free assemblies.
