UVK2A220MED

The UVK2A220MED is a miniature-sized aluminum electrolytic capacitor from Nichicon’s UVK series, configured as a radial-lead, standard-type component. It provides 22 µF capacitance at a 100 V rating with a compact φ6.3 × 11 mm can and 2.5 mm lead spacing, intended for general-purpose electronic applications that require polarized bulk capacitance in a small through-hole package.

Designed for reliable operation across an industrial temperature range (−40 °C to +85 °C) and specified for 2000 hours at 85 °C, this part balances electrical performance and endurance for use in power-supply filtering and other general-purpose circuits.

Key Features

• Core Electrical — 22 µF nominal capacitance with ±20% tolerance and a 100 V rated voltage for mid-to-high-voltage rail applications.
• Frequency & Loss — Tangent of loss angle (tanδ) specified as 0.08 at 20 °C, 120 Hz (measurement condition at rated 100 V), supporting predictable AC characteristics at line and audio frequencies.
• Ripple & Leakage — Low-frequency ripple current 130 mA (120 Hz) and high-frequency ripple current 260 mA (10 kHz), with a measured leakage current of 66 µA.
• Reliability & Endurance — Endurance rated for 2000 hours at 85 °C with specified limits on capacitance change, tanδ increase and leakage current after the test interval.
• Package & Mounting — Radial lead (through-hole) can with overall size φ6.3 × 11 mm and 2.5 mm lead spacing; available in bulk (no terminal forming) or bag packing.
• Environmental Compliance — RoHS compliant as indicated for the UVK series.
• Miniature Series Design — UVK series is specified as a miniature-sized family (one rank smaller case sizes than UVR), enabling reduced PCB footprint where space is constrained.

Typical Applications

• General-purpose power filtering — Bulk capacitance for smoothing and filtering on intermediate- and higher-voltage rails up to 100 V, using specified ripple current ratings to guide thermal and life considerations.
• Decoupling in control circuits — 22 µF capacitance with low tanδ at 120 Hz supports decoupling and energy buffering in through-hole mounted control electronics.
• Industrial and instrumentation electronics — Polarized, high-voltage-capable electrolytic for general-purpose energy storage and filtering across a −40 °C to +85 °C operating range.

Unique Advantages

• Small footprint for through-hole designs: Miniature φ6.3 × 11 mm can reduces PCB space compared with larger radial electrolytics.
• High working voltage: 100 V rating allows use on higher-voltage rails where mid-range electrolytic capacitance is required.
• Defined AC performance: Specified tanδ (0.08 at 20 °C, 120 Hz) provides predictable loss characteristics for frequency-dependent designs.
• Measured ripple capability: Separate low- and high-frequency ripple current specs (130 mA at 120 Hz, 260 mA at 10 kHz) let designers size components against expected ripple spectra.
• Endurance specification: 2000 hours at 85 °C endurance data enables life-cycle planning for thermal stress environments.
• RoHS compliance: Meets RoHS requirements as indicated for the UVK series.
