The UVY1H103MRD is a Nichicon UVY series aluminum electrolytic capacitor in a radial-lead can. It provides high bulk capacitance (10 000 µF) at a 50 V rating in a compact φ16 × 30.5 mm package for general-purpose electronic use.

Key technical attributes include a wide operating temperature range (−55 °C to 105 °C), a rated endurance of 2000 hours at 105 °C, and RoHS compliance. Note: this part is currently listed as End Of Life.

Key Features

• Capacitance & Voltage — 10 000 µF (10 mF) rated at 50 V, suitable for bulk energy storage and smoothing in power circuits.
• Temperature & Endurance — Rated operating range −55 °C to 105 °C with an endurance of 2000 hours at 105 °C, meeting the UVY series endurance specification.
• Low Loss Tangent — tanδ = 0.12 measured at 20 °C, 120 Hz, supporting predictable dissipation characteristics at rated conditions.
• Ripple Current Capability — Manufacturer-specified ripple current values include low-frequency and high-frequency ratings (data provided: 1.890 A low-frequency; 2.850 A high-frequency), enabling effective AC ripple handling in filtering applications.
• Leakage Current — Specified leakage current of 15 000 µA at rated conditions for initial sizing and standby loss considerations.
• Radial Can Package — φ16 × 30.5 mm aluminum can with radial leads and 12.5 mm lead spacing (±0.5 mm), supplied in bulk (no terminal forming) or bag packing for through-hole assembly.
• Polarized — Polarized aluminum electrolytic design for DC power circuits and general-purpose applications.
• Regulatory — RoHS compliant as indicated in product data.

Typical Applications

• General-purpose power supplies — Bulk energy storage and smoothing for low- to medium-power DC supplies where a 50 V, high-capacitance solution is required.
• Power filtering — Ripple attenuation and decoupling in power conversion and regulation stages needing high capacitance and rated ripple handling.
• Industrial electronics — Energy buffering and transient suppression in general-purpose industrial control equipment within the specified temperature and endurance limits.

Unique Advantages

• High bulk capacitance: 10 000 µF at 50 V provides substantial energy storage for smoothing and hold-up in compact assemblies.
• Wide temperature range: −55 °C to 105 °C supports deployment across varied thermal environments within the specified limits.
• Endurance at elevated temperature: 2000 hours at 105 °C gives designers a measurable lifetime metric for high-temperature applications.
• Radial through-hole convenience: φ16 can with 12.5 mm lead spacing simplifies mounting and replacement in through-hole boards and legacy layouts.
• Predictable loss behavior: tanδ = 0.12 (20 °C, 120 Hz) helps quantify dissipation for thermal and ESR-related design considerations.
• RoHS compliant: Meets lead‑restriction requirements for environmentally mindful designs.
