UVK1H103MRD

The UVK1H103MRD is a miniature-sized aluminum electrolytic capacitor from Nichicon’s UVK series, presented in a radial-lead can with a 10,000 µF capacitance and a 50 V rated voltage. It is intended for general-purpose electronic applications that require bulk capacitance in a compact form factor.

Key attributes include a wide operating temperature range (−40 °C to 85 °C), a rated endurance of 2000 hours at 85 °C, and measurable ripple current capability at both low and high frequencies, making it suitable where sustained smoothing and decoupling are required within the stated specifications.

Key Features

• Capacitance & Voltage: 10,000 µF nominal capacitance with a 50 V rated voltage and ±20% tolerance at 120 Hz, 20 °C.
• Low Loss (tan δ): tanδ = 0.12 measured at 20 °C, 120 Hz, supporting predictable dissipation characteristics within the specified conditions.
• Ripple Current Capability: Low-frequency ripple current 4.0 A (120 Hz) and high-frequency ripple current 4.6 A (10 kHz) as specified for this part.
• Leakage Current: Specified leakage current of 15,000 µA (as provided for this part configuration).
• Temperature & Endurance: Operating range −40 °C to 85 °C with an endurance rating of 2000 hours at 85 °C when the rated voltage is applied.
• Package & Mounting: Radial lead can (φ25 × 50L) with 12.5 mm lead spacing (±0.5 mm). Available packaged as Bulk (no terminal forming) or Bag packing.
• Series & Size Advantage: UVK series — miniature sized; datasheet notes one rank smaller case sizes than UVR in the same family.
• Regulatory Compliance: Compliant to the RoHS directive (2011/65/EU, (EU)2015/863) as noted in the series documentation.
• Product Status: End Of Life.

Typical Applications

• General-purpose electronic circuits — Provides bulk capacitance (10,000 µF) for smoothing and energy storage in assemblies described as general purpose.
• Power supply filtering (general purpose) — Used in designs within the specified 50 V rating and ripple current limits to manage low- and high-frequency ripple as stated.
• Embedded and industrial electronics (general purpose) — Suited to applications operating within −40 °C to 85 °C with the specified endurance and leakage characteristics.

Unique Advantages

• High bulk capacitance in a compact can: 10,000 µF in a φ25 × 50L radial package supports significant capacitance where board space is constrained.
• Measured ripple performance: Rated ripple currents of 4.0 A (120 Hz) and 4.6 A (10 kHz) give clear design targets for filtering and decoupling under specified conditions.
• Defined reliability window: Endurance specified as 2000 hours at 85 °C with post-test limits provided for capacitance, tanδ and leakage current.
• Wide operating temperature: −40 °C to 85 °C operating range supports deployment across a broad set of general-purpose environments.
• RoHS compliance: Series-level compliance to the RoHS directive is indicated in the manufacturer documentation.
• Flexible packing options: Bulk (no terminal forming) or bag packing to suit assembly and procurement preferences.
