UVK1A223MHD

The UVK1A223MHD is a Nichicon UVK series aluminum electrolytic capacitor offering 22,000 µF (22 mF) capacitance at a 10 V rated voltage in a compact radial-lead can. It is designed for general-purpose electronic applications that require high bulk capacitance in a small, through-hole package.

Key value comes from its miniature φ18 × 40 mm size, radial-lead mounting and defined endurance of 2000 hours at 85°C, making it suitable for designs that need substantial low-voltage energy storage with predictable lifetime characteristics.

Key Features

• High Capacitance — 22,000 µF (22 mF) rated capacitance provides substantial bulk energy storage for low-voltage circuits.
• Rated Voltage — 10 V rated voltage for low-voltage system use.
• Capacitance Tolerance — ±20% tolerance at 120 Hz, 20°C for predictable design margins.
• Loss Characteristic (tan δ) — tan δ = 0.66 measured at 20°C, 120 Hz (DF measurement condition).
• Ripple Current Capability — Low-frequency ripple current 3.4 A (120 Hz) and high-frequency ripple current 3.91 A (10 kHz) to support AC load conditions within the specified frequencies.
• Leakage Current — Specified leakage current of 6,600 µA after rated-voltage application at 20°C.
• Endurance — 2000 hours at 85°C with specified post-test limits for capacitance, tan δ and leakage current.
• Operating Temperature — −40°C to +85°C operating range.
• Package & Mounting — Radial lead, can-style package with lead spacing 7.5 mm (±0.5 mm) for through-hole assembly.
• Compact Dimensions — Physical size φ18 × 40 mm (L: 4 × D: 1.8 cm) for space-conscious designs.
• Packaging Options — Available in bulk (no terminal forming) and bag packing for flexible procurement and assembly handling.
• Compliance & Availability — RoHS compliant and in mass production from Nichicon.

Typical Applications

• General-purpose electronics — Intended for general-purpose circuits that require high-capacitance, low-voltage bulk storage in a radial-lead format.
• Power filtering in compact designs — Provides bulk capacitance and ripple handling where a compact φ18 × 40 mm can is required.
• Through-hole assemblies — Radial-lead package and defined lead spacing make it suitable for conventional through-hole PCB layouts and manual or wave-solder assembly processes.

Unique Advantages

• High bulk capacitance in a small footprint — 22,000 µF in a φ18 × 40 mm can reduces board space required for equivalent capacitance.
• Defined ripple handling across frequencies — Specified ripple currents at 120 Hz and 10 kHz support designers targeting both low- and high-frequency ripple environments.
• Predictable lifetime specification — 2000 h endurance at 85°C with clear post-test limits helps quantify long-term performance.
• Wide operating temperature — −40°C to +85°C range supports deployment across a broad set of ambient conditions.
• Through-hole readiness — Radial lead spacing (7.5 mm ±0.5 mm) and canned package simplify integration into existing through-hole assemblies.
• Regulatory and production status — RoHS compliance and mass-production availability from Nichicon aid procurement and regulatory planning.
