UPV1H4R7MFD

The UPV1H4R7MFD is a miniature, low-impedance aluminum electrolytic capacitor from Nichicon's UPV series. It is a polarized, radial-lead component specified at 4.7 µF and 50 V, designed for general-purpose use in compact electronic assemblies.

Engineered for elevated-temperature operation, the UPV1H4R7MFD delivers a long load life of 5000 hours at +105°C while maintaining low impedance and controlled leakage, making it suitable where space is limited and sustained thermal reliability is required.

Key Features

• Electrical Characteristics — 4.7 µF capacitance at a rated voltage of 50 V with ±20% tolerance; polarized design for DC energy storage and smoothing.
• Low Impedance Performance — Part of Nichicon's low-impedance UPV series, offering reduced AC impedance for improved ripple handling; specified ripple current: 39.69 mA at 120 Hz and 81 mA at 200 kHz.
• High-Temperature Endurance — Rated endurance of 5000 hours at +105°C; after this test the part meets specified limits for capacitance change (within ±30%), tan δ (≤300% of initial specified value), and leakage current (≤ initial specified value).
• Leakage and Dissipation — Series leakage current specification: after 1 minute at 20°C, leakage current is not more than 0.03CV (µA). Tangent of loss angle (tan δ) for 50 V rating is specified up to 0.10 (measurement at 120 Hz, 20°C).
• Compact Radial Package — Radial can package with 2 mm lead spacing and compact dimensions (L: 1.1 × D: 0.5 cm), suited for space-constrained board layouts.
• Wide Operating Temperature — Rated for operation from −55°C to +105°C to support designs exposed to broad temperature ranges.
• Regulatory Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose electronic equipment — Local energy storage and smoothing in compact assemblies where a miniature, polarized capacitor is required.
• Power supply filtering — Output smoothing and ripple reduction in small DC power supplies and regulators, leveraging the capacitor's low impedance and specified ripple current.
• Embedded modules and boards — Decoupling and bulk capacitance for embedded control boards and electronics with limited board area.

Unique Advantages

• Designed for elevated-temperature reliability — 5000 hours at +105°C endurance provides predictable performance in thermal stress conditions.
• Low-impedance behavior — Ripple current ratings at both low and high frequencies support improved AC performance in filtering and smoothing roles.
• Space-efficient form factor — Miniature radial can and small dimensions enable use in densely populated PCB designs.
• Clear electrical limits — Specified leakage current formula and tan δ limits give measurable acceptance criteria for design and testing.
• RoHS compliant — Conforms to applicable RoHS directives for environmental and regulatory requirements.
