UHD1V151MPD

The UHD1V151MPD is a miniature, high-reliability aluminum electrolytic capacitor in Nichicon’s UHD series. It is a radial-lead, polarized capacitor offering 150 µF capacitance at a rated voltage of 35 V, optimized for applications that require low impedance and elevated ripple handling in a compact φ8 × 11.5 mm can.

Designed for general-purpose power filtering and decoupling, this part provides a combination of high ripple current capability, wide operating temperature range, and long endurance for demanding electronic and industrial designs.

Key Features

• Capacitance & Voltage — 150 µF rated capacitance at 35 V, with capacitance tolerance ±20% (120 Hz, 20°C).
• Low Loss / Frequency Performance — Tangent of loss angle (tan δ) 0.12 measured at 120 Hz, 20°C, supporting stable performance in AC ripple conditions.
• High Ripple Current — Low-frequency ripple current 532 mA (120 Hz) and high-frequency ripple current 760 mA (100 kHz), enabling effective smoothing in power circuits across a broad frequency range.
• Leakage Current — Specified leakage current 52.5 µA after application of rated voltage, suitable for power supply and decoupling uses.
• Thermal & Endurance — Rated for operation from −40°C to +105°C with an endurance of 3000 hours at 105°C.
• Package & Mounting — Radial lead, polarized aluminum can with case size φ8 × 11.5 mm and lead spacing 3.5 mm (lead spacing tolerance 0.5 mm); available as bulk or bag packing.
• Environmental Compliance — RoHS compliant.

Typical Applications

• Power Supply Filtering — Smoothing and bulk decoupling for linear and switching power supplies where compact size and elevated ripple handling are required.
• DC–DC Converters — Input/output filtering and transient suppression in DC–DC converter stages that benefit from low impedance at higher frequencies.
• Industrial Control Electronics — Local energy storage and ripple management in control modules operating across −40°C to +105°C.
• Consumer and Communication Equipment — General-purpose decoupling and filtering in space-constrained boards with moderate ripple current demands.

Unique Advantages

• Compact form factor: φ8 × 11.5 mm can provides necessary capacitance while saving PCB area compared to larger radial types.
• High ripple capability across frequencies: Specified ripple currents at both low and high frequencies (532 mA @120 Hz, 760 mA @100 kHz) support effective smoothing in mixed-frequency environments.
• Wide operating range: −40°C to +105°C rating allows deployment in a variety of ambient conditions without compromising performance.
• Long endurance at elevated temperature: 3000 hours at 105°C supports longer service life in thermally stressed designs.
• Low dissipation factor: tan δ of 0.12 at 120 Hz helps reduce heating and energy loss in AC ripple conditions.
• RoHS compliant: Meets RoHS requirements for environmentally responsible designs.
