UHV1V331MPD

The UHV1V331MPD is an aluminum electrolytic capacitor in a radial-lead can, offering 330 µF capacitance at a 35 V rating. It is part of the UHV series designed for low impedance and high ripple-current performance in general-purpose power circuits.

Key attributes include low impedance (133 mΩ), high-frequency ripple capability (1.36 A at 100 kHz), a wide operating temperature range (−40 °C to +105 °C) and a rated endurance of 6000 hours at 105 °C, making it suited to long-life power applications where ripple handling and compact size matter.

Key Features

• Electrical Performance 330 µF capacitance with a rated voltage of 35 V and capacitance tolerance of −20% to +20%.
• Low Loss / Low Impedance Tangent of loss angle (tan δ) of 0.11 (120 Hz, 20 °C, 35 V) and specified impedance of 133 mΩ for improved AC performance.
• High Ripple Capability Rated ripple current 680 mA at 120 Hz and 1.36 A at 100 kHz, targeting demanding ripple and high-frequency applications.
• Leakage & Stability Leakage current specified as 115.5 µA (measured condition in product data), enabling predictable bias behavior after voltage application.
• Reliability & Lifetime Endurance rated for 6000 hours at 105 °C under rated voltage plus ripple, with defined limits for capacitance change, tan δ and leakage current after the test.
• Compact Radial Package Cylindrical can size φ10 × 12.5 mm length, radial-lead mounting with 5 mm lead spacing, available in bulk or bag packing for flexible assembly handling.
• Wide Temperature Range & Compliance Operating temperature range −40 °C to +105 °C and RoHS compliant.

Typical Applications

• Power Supply Filtering Use where low impedance and high ripple current reduce output voltage ripple in general-purpose power supplies.
• DC/DC Converter Support Suitable for bulk decoupling and high-frequency ripple handling in converter output stages up to the 35 V rating.
• Embedded and Electronic Control Modules Compact φ10 × 12.5 mm size offers bulk energy storage in space-constrained boards while supporting long operating temperatures and endurance.
• Industrial Power Circuits Long endurance at 105 °C and specified leakage/tan δ characteristics support reliable operation in continuous-duty power applications.

Unique Advantages

• High ripple tolerance: 1.36 A at 100 kHz and 680 mA at 120 Hz enable robust handling of both low- and high-frequency ripple.
• Low AC loss: tan δ of 0.11 at rated conditions and low impedance (133 mΩ) deliver efficient performance under AC stress.
• Predictable lifetime: 6000 hours at 105 °C with specified end-of-life limits provides a measurable reliability baseline for design planning.
• Compact radial form factor: φ10 × 12.5 mm can with 5 mm lead spacing saves board space while keeping through-hole mounting simplicity.
• RoHS compliant and production-ready: Material compliance and mass-production status simplify procurement and regulatory considerations.
• Measured leakage specification: Defined leakage current (115.5 µA) supports predictable bias and power-loss calculations.
