UPS1V330MDD

The UPS1V330MDD from Nichicon is a miniature, low‑impedance aluminum electrolytic capacitor designed for switching power supplies and general‑purpose circuits. It is a radial‑lead, polarized can type that combines a compact footprint with wide operating temperature capability to support compact power modules and board‑level decoupling.

This part offers a 33 µF capacitance at a 35 V rating, RoHS compliance, and specifications targeted at reliable ripple handling and thermal endurance in demanding environments.

Key Features

• Capacitance & Voltage — 33 µF nominal capacitance with a 35 V rated voltage; capacitance tolerance ±20% (120 Hz, 20°C).
• Low Impedance Design — Marketed as low impedance for improved ripple performance in switching power supplies; frequency‑dependent ripple ratings are provided for application sizing.
• Ripple Current Ratings — Rated ripple current 27.2 mA at 120 Hz and 160 mA at 10 kHz to support filtering and decoupling in switching regulator circuits.
• Wide Temperature Range — Operating temperature −55°C to +105°C suitable for a broad range of thermal environments.
• High‑Temperature Endurance — Lifetime specified as 2000 hours at 105°C (DC bias plus rated ripple current applied per series endurance conditions).
• Dissipation Factor — tan δ ≤ 0.12 (max.) measured at 120 Hz, 20°C for the 35 V rating, useful for assessing AC losses.
• Leakage Current — Series specification: after 1 minute at rated voltage and 20°C, leakage current ≤ 0.03 C V (µA), enabling predictable bias current in designs.
• Compact Radial Package — Radial can with 2 mm lead spacing; dimensions L: 1.1 × D: 0.5 cm and maximum seated height 1.1 cm for tight board layouts.
• Regulatory Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Switching Power Supplies — Bulk and smoothing capacitor for DC‑DC converters and switching regulators where low impedance and predictable ripple handling are required.
• Board‑Level Power Rail Decoupling — Compact footprint makes the part suitable for decoupling and local energy storage on dense PCBs and power modules.
• General‑Purpose Electronics — Useful in consumer and industrial general‑purpose circuits that require polarized electrolytic capacitance within a small radial package.

Unique Advantages

• Space‑Efficient Form Factor: Small L × D footprint (1.1 × 0.5 cm) and radial lead configuration reduce board area for compact designs.
• Designed for Ripple Duty: Published ripple current ratings at 120 Hz and 10 kHz help designers size capacitors for switching environments and AC stress.
• Wide Thermal Range: −55°C to +105°C operating range supports applications exposed to low and high ambient temperatures.
• High‑Temperature Life: Specified 2000 hours at 105°C under rated conditions provides a measurable endurance metric for thermal reliability planning.
• Predictable Electrical Behavior: Specified dissipation factor (tan δ) and leakage current limits allow tighter design margins for loss and bias current calculations.
• Regulatory Confidence: RoHS compliance supports deployment in regions and products requiring restricted‑substance conformance.
