URS1V332MRD

The URS1V332MRD is a miniature, low-profile aluminum electrolytic capacitor from Nichicon’s URS series, specified for general-purpose electronic applications. It is a polarized, radial-leaded, can-type capacitor delivering 3.3 mF capacitance at a 35 V rating, designed where compact size, moderate ripple handling and reliable endurance are required.

As part of the URS family—which provides compact, low-profile capacitors across a broad range of voltages and capacitances—this part is suited to through-hole PCB assemblies needing stable bulk capacitance and predictable thermal and endurance behavior.

Key Features

• Capacitance & Voltage — Rated at 3.3 mF and 35 V, suited for bulk energy storage, filtering and decoupling duties within the specified voltage range.
• Compact, Low‑Profile Package — Radial can package with physical size L: 2.5 × D: 2.0 cm and a seated height of 2.5 cm, enabling space-constrained through-hole layouts.
• Radial Lead Mounting — 1.0 cm lead spacing and radial lead configuration for standard through-hole assembly and prototyping workflows.
• Operating Temperature & Endurance — Rated for operation from −40 °C to +85 °C with an endurance rating of 2000 hours at 85 °C; capacitance change after endurance is specified within ±20%.
• Ripple Current Capability — Rated ripple current: 2.0 A at 120 Hz and 2.3 A at 10 kHz, enabling effective AC ripple handling for power supply smoothing across common frequencies.
• Tolerance & Polarization — Capacitance tolerance is −20% to +20%; the device is polarized and must be installed with correct polarity.
• Leakage Current Specification — Leakage current characterized in the URS series: after 1 minute ≤ 0.03 CV (µA) and after 2 minutes ≤ 0.01 CV (µA), providing predictable leakage behavior.
• Readable Marking — White printing on a black sleeve for easy identification on assembled boards.

Typical Applications

• Power supply smoothing — Bulk capacitance and rated ripple current make the part suitable for smoothing and energy storage in low- to mid-power supplies.
• Decoupling and filtering — 3.3 mF capacitance at 35 V supports decoupling of downstream regulators and reduces low-frequency voltage ripple.
• General-purpose through-hole assemblies — Radial lead spacing and compact can package are convenient for prototyping, repairable designs and PCB layouts that require axial clearance.

Unique Advantages

• Space-efficient bulk capacitance — Compact L: 2.5 × D: 2.0 cm footprint and low-profile construction deliver large capacitance in a small through-hole package.
• Sustained performance at elevated temperature — Endurance specified at 2000 hours at 85 °C, with capacitance stability limits defined for predictable long-term behavior.
• Frequency-aware ripple handling — Specified ripple current at 120 Hz and 10 kHz enables designers to size the capacitor based on application frequency content.
• Clear, manufacturer-specified leakage and loss characteristics — Series leakage current and tan δ limits provide measurable electrical baselines for design validation.
• Through-hole assembly friendly — Standard 1.0 cm lead spacing and radial leads simplify placement and soldering in conventional manufacturing or repair workflows.
• Part of a flexible series — The URS family spans a wide range of voltages and capacitances, making it easier to standardize on a series across multiple design points.
