UVY1V103MRD

The UVY1V103MRD is an aluminum electrolytic capacitor from Nichicon’s UVY series in a radial-lead can. It provides 10,000 µF capacitance at a 35 V rating, packaged in a φ22 × 50 mm case with 10 mm lead spacing (±0.5 mm).

Designed for general-purpose electronic applications that require high bulk capacitance, wide operating temperature range (−55°C to 105°C), and defined endurance (2000 hours at 105°C). Status: End Of Life.

Key Features

• Capacitance & Voltage — 10,000 µF nominal capacitance with tolerance −20% to +20% at a rated voltage of 35 V.
• Wide Temperature Range — Rated for operation from −55°C to 105°C.
• Endurance — 2000 hours at 105°C (meets the UVY series endurance condition after rated-voltage application).
• Loss Tangent (tan δ) — tanδ = 0.32 measured at 20°C and 120 Hz for this part.
• Ripple Current Capability — Low-frequency ripple current 2.65 A (120 Hz) and high-frequency ripple current 3.0475 A (10 kHz), enabling sustained AC loading within specified limits.
• Leakage Current — Specified leakage current of 10,500 µA.
• Package & Mounting — Radial lead, can-style package (φ22 × 50 mm) with 10 mm lead spacing; available in bulk (no terminal forming) or bag packing.
• RoHS Compliance — Compliant with the RoHS directive as noted for the UVY series.
• Series-Level Size Advantage — UVY series offers one rank smaller case sizes compared to UVZ (series-level characteristic).

Typical Applications

• General-purpose electronics — For designs requiring 10,000 µF at 35 V with wide temperature capability (−55°C to 105°C).
• Power systems with bulk capacitance needs — Where long endurance (2000 h at 105°C) and defined ripple handling at 120 Hz and 10 kHz are required.
• Industrial and commercial equipment — Suitable for applications that demand stable capacitance and predictable loss characteristics (tanδ measured at 20°C/120 Hz).

Unique Advantages

• High bulk capacitance in a compact radial can — 10,000 µF in a φ22 × 50 mm package provides substantial energy storage without larger case footprints.
• Wide temperature and defined endurance — −55°C to 105°C rating with 2000-hour endurance at 105°C supports designs exposed to extended temperature ranges.
• Measured AC performance — Specified tanδ (0.32 at 20°C/120 Hz) and explicit ripple current ratings give predictable AC behavior for design validation.
• RoHS-compliant packaging options — Available in bulk or bag packing and compliant with RoHS directive requirements documented for the UVY series.
• Series case-size benefit — Part of the UVY series, which is specified as one rank smaller in case size than the UVZ series for tighter PCB area usage.
