URZ1H331MHD

The URZ1H331MHD from Nichicon is a compact, low-profile radial-lead aluminum electrolytic capacitor in the URZ series. It delivers 330 µF capacitance at a 50 V rating with a wide operating temperature range of −55°C to 105°C, intended for general-purpose electronic designs.

This part combines a small φ12.5 × 12.5 mm case with 5.0 mm lead spacing and polarized radial leads, offering a reliable energy-storage and filtering solution where space is constrained and thermal endurance is required (rated 1000 hours at 105°C).

Key Features

• Capacitance & Voltage: 330 µF nominal capacitance with a 50 V rated voltage and ±20% tolerance, suitable for bulk decoupling and smoothing in general-purpose circuits.
• Compact, Low-Profile Package: φ12.5 × 12.5 mm case size (L: 1.25 × D: 1.25 cm) with radial can construction and 5 mm lead spacing for easy through-hole mounting and dense board placement.
• Wide Temperature Range: Rated for −55°C to 105°C operation, supporting applications that require extended ambient temperature capability.
• Endurance: Designed for 1000 hours at 105°C, meeting the URZ series endurance specification for long-term thermal performance.
• Loss Characteristics (tan δ): tan δ = 0.12 measured at 20°C, 120 Hz for the 50 V rating, enabling predictable dissipation behavior in AC conditions.
• Ripple Current Capability: Low-frequency ripple current 370 mA at 120 Hz and high-frequency ripple current 555 mA at 10 kHz, supporting both mains-frequency and higher-frequency ripple environments.
• Leakage Current: Specified leakage current of 495 µA (measured conditions provided), helping estimate standby loss and insulation performance.
• Packaging & Availability: Supplied in bulk (no terminal forming) / bag packing; part is in mass production.

Typical Applications

• General-purpose power filtering: Used for smoothing and bulk energy storage in general-purpose power supplies and converters where a compact, radial electrolytic is required.
• Decoupling on through-hole PCBs: Provides local energy reservoir and decoupling for circuits using through-hole components with 5 mm lead spacing.
• Thermally stressed designs: Suitable for applications that require operation up to 105°C with a 1000-hour endurance rating at that temperature.

Unique Advantages

• Space-efficient low-profile form: φ12.5 × 12.5 mm case packs 330 µF into a compact footprint for board-level space savings.
• Wide temperature tolerance: −55°C to 105°C rating supports deployments across broad ambient conditions without spec compromise.
• Measured ripple capability: Defined ripple current values at both 120 Hz and 10 kHz let designers size thermal and ripple handling with confidence.
• Predictable dissipation: Specified tan δ (0.12 at 20°C, 120 Hz) provides a clear reference for loss and heating calculations.
• Long-duration thermal endurance: 1000-hour life at 105°C supports longevity in elevated-temperature applications.
• Production-ready supply: Mass production status and bulk/bag packing options simplify procurement and assembly planning.
