URS2C221MRD

The URS2C221MRD is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon’s URS series. It delivers 220 µF capacitance at a 160 V rated voltage in a compact φ20 × 25 mm can, intended for general-purpose electronic designs.

Engineered for compact power filtering and smoothing in through-hole assemblies, the device combines a wide operating temperature range (−40°C to 85°C) with a 2000‑hour endurance rating at 85°C to support reliable performance in demanding ambient conditions.

Key Features

• Capacitance & Tolerance — 220 µF nominal capacitance with tolerance of −20% to +20% for predictable bulk energy storage.
• High Rated Voltage — 160 V rated voltage suitable where elevated DC bus voltages are required.
• Low‑profile radial package — φ20 × 25 mm can in a radial‑lead form with 10 mm lead spacing (±0.5 mm), simplifying through‑hole placement and PCB layout.
• Frequency and ripple handling — Low frequency ripple current 770 mA at 120 Hz and high frequency ripple current 1.232 A at 10 kHz, supporting a range of filtering and smoothing applications.
• Loss factor (tan δ) — tan δ = 0.2 (measured at 20°C, 120 Hz, 160 V) for characterization of dissipation in AC conditions.
• Leakage and endurance — Leakage current specified at 1508 µA and rated endurance of 2000 hours at 85°C, with performance criteria defined after restoration to 20°C.
• Operating temperature range — −40°C to +85°C to cover a broad set of environmental conditions.
• Packaging options — Supplied as bulk (no terminal forming) or bag packed to suit prototype and production handling preferences.

Typical Applications

• General-purpose power circuits — Bulk energy storage and smoothing for through‑hole power supply and converter designs that require 220 µF at 160 V.
• Filtering and decoupling — AC ripple reduction and decoupling in circuits where elevated voltage rating and compact radial cans are desired.
• Industrial electronics — Power conditioning in equipment that operates within the −40°C to +85°C temperature range and benefits from a 2000‑hour endurance at elevated temperatures.

Unique Advantages

• High-voltage capability: 160 V rating enables use on higher DC rails without changing topology or capacitor family.
• Compact, serviceable form factor: φ20 × 25 mm radial can and 10 mm lead spacing make the part easy to place and replace in through‑hole designs.
• Clear performance metrics: Specified ripple currents (770 mA @120 Hz, 1.232 A @10 kHz) and tan δ value (0.2) allow accurate thermal and ripple budgeting.
• Designed endurance: 2000 hours at 85°C provides a defined reliability baseline for thermal stress planning.
• Simple procurement and handling: Bulk or bag packing options accommodate prototype runs and larger production batches.
