UVR2W101MRD

The UVR2W101MRD is a polarized aluminum electrolytic capacitor in a radial-lead can, offering 100 µF capacitance at a 450 V rated voltage. It belongs to Nichicon’s UVR miniature series, designed for general-purpose and entertainment electronics where high-voltage filtering and compact radial mounting are required.

Key measurable attributes include a 100 µF nominal capacitance with ±20% tolerance, a -25 °C to 85 °C operating range (for 450 V parts), and a 2000-hour endurance rating at 85 °C. The part is RoHS compliant.

Key Features

• Capacitance & Voltage — 100 µF nominal capacitance with a 450 V rated voltage; capacitance tolerance is -20% to +20% (measured at 120 Hz, 20 °C).
• Loss Angle (tan δ) — tan δ = 0.25 measured at 20 °C, 120 Hz, providing a specified dissipation characteristic for design margining.
• Ripple Current Handling — Low-frequency ripple current 350 mA at 120 Hz and high-frequency ripple current 560 mA at 10 kHz, enabling bulk filtering and ripple suppression across frequency ranges.
• Leakage Current — Specified leakage current of 1900 µA under rated conditions, useful for predicting standby and bias currents in high-voltage circuits.
• Reliability & Endurance — Rated for 2000 hours at 85 °C (endurance condition per series specification), with capacitance and leakage limits defined after the test.
• Form Factor & Mounting — Radial-lead can with body dimensions φ22 × 40 mm and 10 mm lead spacing (±0.5 mm); available in bulk or bag packing.
• Environmental Compliance — RoHS compliant as stated in product data.
• Product Status — End Of Life.

Typical Applications

• High-voltage power supplies — Bulk filtering and energy storage on 450 V DC rails where a compact radial electrolytic is required.
• Entertainment electronics — Fits designs within the UVR series target segment for consumer/entertainment devices requiring miniature high-voltage capacitors.
• AC/DC converter smoothing — Ripple suppression across low and high frequencies, leveraging specified ripple current ratings at 120 Hz and 10 kHz.

Unique Advantages

• High-voltage capability: 450 V rating allows application directly on elevated DC rails without series stacking.
• Measured dissipation characteristic: tan δ specified (0.25 at 20 °C, 120 Hz) helps designers assess ESR-related losses and thermal rise.
• Frequency-versatile ripple handling: Distinct ripple current values at 120 Hz and 10 kHz provide quantifiable behavior for both mains-frequency smoothing and higher-frequency switching noise.
• Thermal endurance data: 2000 hours at 85 °C endurance rating gives a defined baseline for lifetime planning in elevated-temperature environments.
• Compact radial package: φ22 × 40 mm can and 10 mm lead spacing deliver a space-efficient radial solution for through-hole layouts.
• RoHS compliance: Environmentally compliant construction suitable for regulated markets.
