UHD1V221MPD

The UHD1V221MPD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UHD series designed for general-purpose electronic applications that require high ripple handling and low impedance at higher frequencies. It provides 220 µF capacitance at a 35 V rating in a compact φ8 × 15 mm can with radial leads and 3.5 mm lead spacing.

Built for continuous operation across a wide temperature range and long endurance, this part addresses power filtering, decoupling and ripple-current demands in compact board layouts while offering RoHS compliance and production-ready packaging options.

Key Features

• Electrical performance — 220 µF nominal capacitance with ±20% tolerance and polarization suitable for DC applications; rated at 35 V.
• High ripple capability — Low-frequency ripple current 696.5 mA (120 Hz) and high-frequency ripple current 995 mA (100 kHz) to support demanding AC ripple conditions.
• Low loss at rated voltage — tan δ = 0.12 (measured at 20°C, 120 Hz for 35 V rating), enabling lower dissipation in filtering and decoupling roles.
• Compact radial package — φ8 × 15 mm case with 3.5 mm lead spacing (±0.5 mm) and radial can mount for tight board placement; typical lead diameter φd = 0.6 mm for φ8 case.
• Temperature and endurance — Operates from −40°C to +105°C with rated endurance of 3000 hours at 105°C under rated DC bias plus rated ripple current.
• Leakage current — Product-specific leakage current of 77 µA (after specified test conditions), supporting stable long-term operation.
• Compliance & packaging — RoHS compliant; available in bulk (no terminal forming) or bag packing. Status: Mass Production.

Typical Applications

• Power supply filtering — Smooths DC bus and output rails where high ripple current capacity and compact size are required.
• DC–DC converter output caps — Provides decoupling and energy buffering on converter outputs benefiting from low impedance at higher frequencies.
• General-purpose board-level decoupling — Fits dense PCB layouts that need radial lead mounting and reliable performance across −40°C to +105°C.

Unique Advantages

• High ripple-handling in a small footprint: 696.5 mA at 120 Hz and 995 mA at 100 kHz enable robust ripple performance without large case sizes.
• Lower high-frequency impedance: UHD series design and a measured tan δ of 0.12 help reduce losses in high-frequency filtering tasks.
• Compact radial form factor: φ8 × 15 mm can and 3.5 mm lead spacing simplify placement in space-constrained designs while retaining through-hole mounting convenience.
• Durability under elevated temperature: Rated for 3000 hours at 105°C, supporting long-term stability in high-temperature environments.
• Production-ready and compliant: RoHS compliance, mass-production status and simple bulk/bag packaging options streamline procurement and assembly.

Why Choose UHD1V221MPD?

The UHD1V221MPD combines the high-ripple, low-impedance characteristics of the UHD series with a compact radial can, making it suitable for designs that demand effective power filtering and decoupling in limited board space. Its 35 V rating, clearly specified ripple currents, and endurance rating make selection and sizing straightforward for engineers targeting reliable DC performance.

This part is well suited to general-purpose electronic designs that require a balance of compact packaging, measurable ripple capability, and long-term thermal endurance, backed by RoHS compliance and production availability.
