URS2E330MHD

The URS2E330MHD is a Nichicon URS-series miniature aluminum electrolytic capacitor in a radial-lead, standard-type can package. It delivers 33 µF capacitance with a 25 V rated voltage and is designed for general-purpose power filtering and decoupling in compact through-hole assemblies.

Its compact case (φ18 × 20 mm) and 7.5 mm lead spacing make it suitable for space‑constrained boards that require polarized bulk capacitance with extended endurance and a wide operating temperature range.

Key Features

• Capacitance & Tolerance  33 µF nominal with ±20% tolerance (–20% ~ +20%) at 120 Hz, 20°C.
• Rated Voltage  25 V DC rated voltage suitable for a range of low‑voltage power rails.
• Compact Radial Can  Radial lead, can-style package with a case size of φ18 × 20 mm and 7.5 mm lead spacing for through‑hole assembly.
• Operating Temperature  Specified for –40°C to +85°C operation to cover common industrial and consumer environments.
• Endurance  Rated for 2000 hours at 85°C with defined limits for capacitance change, tan δ and leakage current after test.
• Loss Characteristics (tan δ)  Series specification provides maximum tan δ values at 120 Hz and 20°C (for a 25 V rated device the max tan δ is 0.16), supporting predictable AC loss behavior.
• Ripple Current Capability  Specified ripple current values support AC ripple handling; frequency‑dependent coefficients and ripple ratings are provided in the URS series specification.
• Polarized  Standard polarized aluminum electrolytic construction for bulk energy storage and smoothing applications.

Typical Applications

• Power supply filtering  Bulk decoupling and smoothing on low‑voltage DC rails where 25 V rating and 33 µF capacitance are appropriate.
• Consumer electronics  Through‑hole assemblies in compact consumer devices requiring polarized bulk capacitance and a low‑profile can.
• Industrial control  Local energy storage and ripple suppression in control boards operating across –40°C to +85°C.
• General purpose electronics  Circuit designs needing a reliable, compact aluminum electrolytic for decoupling, timing reservoirs or smoothing.

Unique Advantages

• Compact, low‑profile design: φ18 × 20 mm can offers significant capacitance in a small footprint for space‑limited PCBs.
• Through‑hole reliability: Radial lead construction simplifies assembly and provides robust mechanical connection for vibration-prone environments.
• Endurance-rated: 2000 hours at 85°C endurance rating gives predictable long-term performance for sustained operating temperatures.
• Broad operating range: –40°C to +85°C capability supports a wide set of deployment environments without additional qualification claims.
• Series documentation: URS-series specifications include detailed tan δ, leakage current formula and frequency coefficients for ripple current, enabling precise design margining.
