UVY1V331MPD

The UVY1V331MPD is a Nichicon UVY-series aluminum electrolytic capacitor in a radial-lead can package, rated 330 µF at 35 V. It is designed as a general-purpose polarized capacitor for applications that require bulk capacitance, ripple handling and operation across a wide temperature range.

Key attributes include a compact φ10 × 12.5 mm can, a rated temperature range of -55°C to 105°C, endurance of 2000 hours at 105°C, and defined ripple and leakage characteristics suitable for power filtering and supply stabilization in electronic systems.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a rated voltage of 35 V and capacitance tolerance of -20% to +20%.
• Temperature Range — Rated to operate from -55°C to 105°C, supporting circuits that experience wide ambient or thermal variation.
• Ripple Current Performance — Low-frequency ripple current of 350 mA (120 Hz) and high-frequency ripple current of 525 mA (10 kHz), enabling effective AC ripple smoothing at both mains and switching frequencies.
• Electrical Losses & Leakage — Tangent of loss angle (tan δ) of 0.14 (measured at 20°C, 120 Hz) and measured leakage current of 346.5 µA, providing predictable dissipation and standby current behavior.
• Endurance — Life rating of 2000 hours at 105°C with specified limits on capacitance change and tan δ after the endurance test.
• Mechanical & Mounting — Radial lead mounting with 5 mm lead spacing (±0.5 mm) and a compact case size φ10 × 12.5 mm for through-hole PCB designs.
• RoHS Compliance — Compliant with RoHS requirements for lead-free material restrictions.

Typical Applications

• Power Supply Filtering — Bulk decoupling and smoothing for linear and switching power supplies where 330 µF at 35 V and defined ripple ratings are required.
• Embedded & Industrial Electronics — Stabilizing DC rails in controllers and instrumentation operating across -55°C to 105°C ambient ranges.
• Consumer Electronics — Energy storage and transient suppression in devices that use through-hole radial components and require reliable leakage and loss specifications.

Unique Advantages

• Compact radial can — φ10 × 12.5 mm case provides significant capacitance in a small footprint for space-constrained through-hole designs.
• Wide operating temperature — -55°C to 105°C rating supports applications exposed to broad thermal environments without derating outside specified limits.
• Defined ripple capability — Separate low-frequency and high-frequency ripple current ratings (350 mA @120 Hz and 525 mA @10 kHz) let designers size capacitors against expected ripple spectra.
• Long endurance at elevated temperature — 2000 hours life at 105°C provides a measurable reliability baseline for thermal-stressed applications.
• Predictable electrical characteristics — Specified tan δ (0.14 at 20°C, 120 Hz) and leakage current (346.5 µA) enable predictable loss and standby current budgeting.
• Regulatory compliance — RoHS compliance simplifies material-conformity planning for production and procurement.
