UVK1H4R7MDD

The UVK1H4R7MDD from Nichicon is a miniature radial-lead aluminum electrolytic capacitor in the UVK series, offering 4.7 µF capacitance with a 50 V rated voltage. It is a standard polarized, through-hole component intended for general-purpose power-filtering and decoupling use in compact electronic assemblies.

Designed for space-constrained designs, the part combines low-frequency and high-frequency ripple handling with endurance at elevated temperature, making it suitable for a range of consumer and industrial electronic applications that require reliable, compact bulk capacitance.

Key Features

• Capacitance & Tolerance — 4.7 µF nominal capacitance with ±20% tolerance (measured at 120 Hz, 20°C), providing predictable filtering characteristics.
• Rated Voltage — 50 V working voltage for mid-range power rails and supply decoupling.
• Loss Characteristic (tan δ) — tan δ = 0.12 at 20°C, 120 Hz, supporting stable AC performance for filtering applications.
• Ripple Current Capability — Low-frequency ripple current 40 mA (120 Hz) and high-frequency ripple current 80 mA (10 kHz), allowing handling of both mains-frequency and higher-frequency switching components.
• Leakage Current — Specified leakage current of 7.05 µA, useful for low-standby-power designs and predictable bias behavior.
• Temperature & Endurance — Operating range −40°C to +85°C with endurance of 2000 hours at 85°C, suitable for extended operation at elevated ambient temperatures.
• Miniature Radial Can Package — Compact φ5 × 11 mm can with 2 mm lead spacing (lead spacing tolerance ±0.5 mm), available in bulk or bag packing for through-hole assembly.
• RoHS Compliance — Compliant with RoHS requirements for restriction of hazardous substances.

Typical Applications

• Power Supply Filtering — Bulk and smoothing capacitor on intermediate rails where 50 V rating and 4.7 µF value provide effective ripple reduction for compact converters.
• Decoupling for Power Modules — Through-hole radial form factor offers robust mounting for decoupling near discrete regulators and power transistors.
• Consumer and Industrial Electronics — Space-constrained designs in instrumentation, controls, and handheld devices that require reliable capacitor performance over −40°C to +85°C.
• Noise Suppression — Use at input/output nodes to attenuate switching noise, leveraging both low- and high-frequency ripple current specifications.

Unique Advantages

• Compact, space-saving footprint — Miniature φ5 can offers bulk capacitance in a small radial package for denser board layouts.
• Balanced ripple performance — Specified ripple current at both 120 Hz and 10 kHz supports mixed-frequency filtering needs in switched and linear supplies.
• Predictable leakage and loss — Low leakage current and defined tan δ at standard test conditions help with predictable bias and thermal planning.
• Extended high-temperature endurance — 2000 hours at 85°C provides a measurable reliability baseline for elevated-temperature operation.
• Through-hole robustness — Radial lead configuration simplifies assembly and provides mechanical stability where wire-leaded mounting is preferred.
• Compliance-ready — RoHS compliance supports regulatory requirements for modern electronic products.
