URZ1H222MRD

The URZ1H222MRD is a radial-lead aluminum electrolytic capacitor in the Nichicon URZ series, offering 2200 µF capacitance with a 50 V rated voltage. It is a compact, low-profile radial can designed for general-purpose power applications that require high capacitance density and reliable ripple handling.

Key electrical characteristics include a capacitance tolerance of ±20%, tan δ = 0.12 (measured at 20°C, 120 Hz), leakage current of 330 µA, low-frequency ripple current of 1.25 A (120 Hz) and high-frequency ripple current of 1.4375 A (10 kHz). The capacitor is rated for operation from −55°C to +105°C with an endurance of 1000 hours at 105°C. Status: End Of Life.

Key Features

• Capacitance & Voltage — 2200 µF nominal capacitance with ±20% tolerance at a 50 V rating.
• Loss and Leakage — tan δ = 0.12 (20°C, 120 Hz) and leakage current specified at 330 µA for predictable DC performance.
• Ripple Current Performance — Low-frequency ripple current 1.25 A at 120 Hz and high-frequency ripple current 1.4375 A at 10 kHz (values provided at 105°C).
• Wide Temperature Range & Endurance — Operates from −55°C to +105°C with a rated endurance of 1000 hours at 105°C.
• Compact Radial Package — Can-style radial package with dimensions φ20 × 25 mm and lead spacing 10 mm, suitable for through-hole mounting.
• Packaging Options — Supplied bulk (no terminal forming) or in bag packing to match assembly handling preferences.

Typical Applications

• General-purpose power supplies — Bulk energy storage and smoothing on 50 V rails where high capacitance and ripple capability are required.
• Power converter filtering — Decoupling and input/output filtering for converters and regulators that operate within the capacitor’s voltage and temperature limits.
• Industrial equipment — Energy storage and smoothing in equipment that requires operation across −55°C to +105°C and long endurance at elevated temperature.

Unique Advantages

• High-capacitance solution: 2200 µF provides substantial bulk storage for smoothing and hold-up on 50 V systems, reducing the need for multiple smaller capacitors.
• Measured loss and leakage specs: Specified tan δ and leakage current values allow predictable thermal and DC performance in design calculations.
• Frequency-aware ripple ratings: Separate ripple current figures for 120 Hz and 10 kHz help quantify performance across low and high frequency loads.
• Wide operating range: −55°C to +105°C temperature rating with 1000-hour endurance at 105°C supports demanding thermal environments.
• Through-hole radial format: φ20 × 25 mm can with 10 mm lead spacing simplifies replacement and prototyping on conventional PCB layouts.
