UPTW6270MHD

The UPTW6270MHD from Nichicon is a radial-leaded aluminum electrolytic capacitor in the UPT series, specified at 27 µF and 420 V. It combines a miniature radial can (φ12.5 × 30.5 mm) with high ripple-current capability and long-life endurance for general-purpose high-voltage applications.

Designed for operation over −40°C to 105°C with a rated endurance of 5000 hours at 105°C, this part suits applications that require sustained high-voltage ripple handling and reliable long-term performance.

Key Features

• Electrical Rating: 27 µF capacitance at a rated voltage of 420 V and capacitance tolerance of ±20% (120 Hz, 20°C).
• High Ripple Current Capability: Rated ripple currents of 240 mA at 120 Hz and 384 mA at 10 kHz support heavy AC ripple environments; suitable for circuits with significant high-frequency ripple content.
• Loss Characteristics: Tangent of loss angle (tan δ) up to 0.20 at 120 Hz and 20°C for the 420 V rating, allowing designers to account for dissipation in thermal budgets.
• Leakage Current: Specified leakage current of 690.4 µA (measured per the product data), useful for estimating standby losses and charge/discharge behavior.
• Long Life at Elevated Temperature: Endurance of 5000 hours at 105°C under rated DC bias plus ripple, with defined limits for capacitance change, tan δ, and leakage after test.
• Compact Radial Package: φ12.5 × 30.5 mm can with 5.0 mm lead spacing (lead spacing tolerance ±0.5 mm), available in bulk or bag packing for through-hole assembly workflows.
• Wide Operating Range & Compliance: Operating temperature range −40°C to 105°C and RoHS-compliant construction.

Typical Applications

• Ballast Circuits — Suited for ballast applications where high ripple current tolerance is required.
• General-Purpose High-Voltage Filtering — 420 V rating and 27 µF capacitance for DC-link or high-voltage filter duties in compact, through-hole designs.
• Long-Life Power Circuits — Use in designs that require sustained operation at elevated temperature thanks to a 5000-hour endurance at 105°C.

Unique Advantages

• High ripple-current handling: Rated ripple currents at both 120 Hz and 10 kHz let you design for mixed-frequency ripple environments without oversizing the capacitor.
• Designed for elevated-temperature durability: 5000-hour life specification at 105°C ensures predictable performance in thermally demanding assemblies.
• Compact radial can form factor: φ12.5 × 30.5 mm size and 5 mm lead spacing deliver a small footprint for through-hole boards while preserving capacitance and voltage rating.
• Quantified dielectric loss and leakage: Specified tan δ (0.20 at 420 V, 120 Hz) and measured leakage current (690.4 µA) provide the electrical parameters needed for thermal and power-loss analysis.
• RoHS-compliant construction: Meets RoHS requirements for environmentally restricted-substance compliance.
• Readily available packaging options: Offered in bulk (no terminal forming) or bag packing to match assembly and inventory handling preferences.
