UVK1H222MHD

The UVK1H222MHD is a radial-lead aluminum electrolytic capacitor from Nichicon's UVK series, designed for general-purpose through-hole applications. It delivers 2.2 mF (2200 µF) capacitance at a 50 V rating in a compact φ16 × 30.5 mm can, combining high capacitance with a miniature-sized profile.

Key technical attributes include a -40°C to 85°C operating range, 2000 hours endurance at 85°C, measurable low- and high-frequency ripple current capability, and RoHS compliance—making it suitable for a wide range of standard electronic power and energy-storage functions.

Key Features

• Capacitance & Voltage — 2200 µF capacitance rated at 50 V for bulk energy storage and decoupling in mid-voltage circuits.
• Radial Lead Through-Hole Package — Radial, can-style package with 7.5 mm lead spacing (±0.5 mm) for standard through-hole assembly and hand or wave soldering.
• Compact Miniature Size — Body dimensions φ16 × 30.5 mm (L: 3.05 × D: 1.6 cm) provide high capacitance in a reduced footprint; part of the UVK miniature-sized series.
• Ripple Current Performance — Low-frequency ripple current of 1.98 A (120 Hz) and high-frequency ripple current of 2.277 A (10 kHz) to support smoothing under AC and switching conditions.
• Loss and Leakage Characteristics — Specified tanδ (DF) of 0.14 measured at 20°C, 120 Hz and a leakage current of 3300 µA, with endurance retention requirements defined over the rated life.
• Endurance & Temperature — Rated life of 2000 hours at 85°C and an operating temperature range of -40°C to 85°C for sustained performance under elevated temperature conditions.
• Packaging Options — Available in bulk (no terminal forming) or bag packing to suit prototyping and production handling preferences.
• Compliance — RoHS compliant as part of the UVK series manufacturing and material standards.

Typical Applications

• General Power Supply Filtering — Bulk capacitance and specified ripple current make the UVK1H222MHD suitable for smoothing and filtering in mid-voltage power supplies.
• Decoupling for Discrete Electronics — Radial lead format and compact size support decoupling and energy storage in general-purpose through-hole circuit designs.
• Industrial and Consumer Electronics — Designed for general-purpose use where durable capacitance, temperature tolerance, and straightforward mounting are required.

Unique Advantages

• High Capacitance in a Small Footprint: 2200 µF in a φ16 × 30.5 mm can delivers significant energy density for size-constrained designs.
• Mid-Voltage Capability: 50 V rating supports a broad range of supply rails without over-specifying voltage margin.
• Through-Hole Simplicity: 7.5 mm lead spacing and radial can package simplify placement and soldering for traditional PCB assembly methods.
• Measured Ripple Endurance: Specified ripple current values at 120 Hz and 10 kHz provide quantifiable performance for both low- and high-frequency filtering tasks.
• Robust Temperature and Lifetime Specs: -40°C to 85°C operating range and 2000 hours endurance at 85°C give predictable lifetime behavior under elevated temperature stress.
• RoHS-Compliant Manufacturing: Conforms to RoHS requirements as part of the UVK series, supporting regulatory-driven designs.
