UVR2F221MRD

The UVR2F221MRD from Nichicon is a miniature, standard-type aluminum electrolytic capacitor in the UVR series, supplied in a radial lead can package. It delivers 220 µF capacitance at a 315 V rated voltage and is intended for general-purpose and entertainment-electronics applications that require through-hole, radial-lead components.

Key electrical and mechanical attributes include a wide operating temperature range of −40°C to +85°C, rated endurance of 2000 hours at 85°C, defined ripple current performance at both low and high frequencies, and RoHS compliance.

Key Features

• Capacitance and Voltage — 220 µF nominal capacitance with a 315 V rated working voltage; capacitance tolerance is −20% to +20%.
• Package and Mounting — Radial lead can package (φ22 × 50 mm length) with 10 mm lead spacing (±0.5 mm); available in bulk or bag packing (no terminal forming).
• Temperature and Endurance — Operating range −40°C to +85°C with endurance specified as 2000 hours at 85°C under rated voltage.
• Ripple Current Performance — Low-frequency ripple current: 850 mA at 120 Hz; high-frequency ripple current: 1.36 A at 10 kHz.
• Leakage and Dissipation — Specified leakage current 2872 µA; tangent of loss angle (tan δ) 0.2 measured at 20°C, 120 Hz.
• Polarized, Standard Series — Polarized aluminum electrolytic type from Nichicon’s UVR miniature series, noted as a standard series for entertainment electronics.
• Regulatory — RoHS compliant.

Typical Applications

• Entertainment Electronics — Suited to designs in the entertainment-electronics segment where miniature radial electrolytic capacitors are specified.
• General-Purpose Electronics — Applicable to general-purpose circuits requiring 220 µF capacitance at elevated DC voltages with through-hole mounting.
• Through-Hole Assemblies and Repairs — Form factor and standard radial lead spacing make it appropriate for replacement or assembly in through-hole PCB designs.

Unique Advantages

• High Working Voltage: 315 V rating supports higher-voltage DC applications within the specified temperature and endurance limits.
• Defined Endurance: 2000-hour life at 85°C provides a clear, testable reliability metric for thermal-stressed applications.
• Dual-Frequency Ripple Data: Specified ripple currents at 120 Hz and 10 kHz allow designers to evaluate performance for both low- and high-frequency filtering.
• Compact Radial Can: φ22 × 50 mm footprint with 10 mm lead spacing for straightforward through-hole integration and retrofit.
• Measured Dissipation and Leakage: tan δ = 0.2 (20°C, 120 Hz) and a specified leakage current of 2872 µA enable predictable power-loss and standby-current budgeting.
• RoHS Compliance: Meets RoHS requirements for restricted substances in applicable regions.

Why Choose UVR2F221MRD?

The UVR2F221MRD is positioned as a compact, radial-lead aluminum electrolytic capacitor for general-purpose and entertainment-electronics designs that require 220 µF at 315 V. Its combination of defined endurance (2000 h at 85°C), measured ripple-current performance at both low and high frequencies, and explicit leakage and dissipation specs make it straightforward to evaluate for thermal, power-loss, and lifetime requirements.

This part is suited to engineers specifying through-hole electrolytic capacitors who need clear, verifiable electrical and mechanical parameters—particularly where a miniature radial can with 10 mm lead spacing is required. The Nichicon UVR series designation and RoHS compliance add clarity for environmental and series-level selection.
