UHW1H270MDD

The UHW1H270MDD is a radial-lead aluminum electrolytic capacitor in Nichicon’s UHW series, offering a compact φ5×11 mm can with radial leads and a 2.0 mm lead spacing. Designed for general-purpose electronics, it delivers a balance of capacitance and voltage handling in a miniature package.

This part provides measurable high-frequency performance and reliability characteristics from the UHW family, including a -40°C to 105°C operating range and specified ripple-current capability for both low and high frequency applications.

Key Features

• Capacitance & Voltage — 27 µF nominal capacitance at a rated voltage of 50 V with tolerance of -20% to +20%.
• Compact Radial Package — φ5×11 mm can with 2.0 mm lead spacing (±0.5 mm) for space-constrained through-hole designs.
• Ripple Current Performance — Low-frequency ripple current 180 mA at 120 Hz and high-frequency ripple current 450 mA at 10 kHz, supporting smoothing and decoupling under varying frequency conditions.
• Low Loss — Tangent of loss angle (tan δ) of 0.1 measured at 20°C, 120 Hz, indicating controlled dissipation for stable operation.
• Low Leakage — Specified leakage current of 13.5 µA, supporting improved hold-up and low-standby-loss circuits.
• Temperature & Endurance — Rated for operation from -40°C to 105°C with an endurance specification of 7000 hours at 105°C.
• Polarized, RoHS-compliant — Polarized aluminum electrolytic construction and RoHS compliance for regulatory alignment.
• Packaging Options — Supplied in bulk (no terminal forming) or bag packing to match assembly and handling preferences.

Typical Applications

• General-purpose power filtering — Compact smoothing and reservoir capacitor in small power supplies where space is limited and 50 V rating is required.
• Decoupling in power stages — Local decoupling for regulators and DC/DC converter outputs where controlled loss (tan δ) and specified ripple currents are important.
• Consumer and industrial electronics — General-purpose use in board-level circuits that require a small, polarized electrolytic with a wide operating temperature range.

Unique Advantages

• Space-efficient form factor: φ5×11 mm can and short lead spacing enable denser through-hole layouts without sacrificing capacitance.
• Frequency-flexible ripple handling: Distinct low- and high-frequency ripple current ratings (180 mA @120 Hz, 450 mA @10 kHz) allow designers to assess performance across typical power-supply frequencies.
• Controlled dissipation: A tan δ of 0.1 at 20°C/120 Hz supports predictable thermal and electrical behavior in decoupling and filtering roles.
• Wide temperature span: -40°C to 105°C operating range supports deployment across diverse environmental conditions.
• Long endurance rating: 7000 hours at 105°C provides a clear reference for expected lifetime under elevated-temperature stress.
• Low leakage: 13.5 µA leakage current helps maintain charge retention and reduces standby losses in low-current circuits.

Why Choose UHW1H270MDD?

UHW1H270MDD combines a compact radial can, a practical 27 µF/50 V rating, and defined ripple-current performance to serve general-purpose power and decoupling needs in space-constrained through-hole designs. Its -40°C to 105°C operating range and 7000-hour endurance at 105°C make it suitable for applications that require consistent electrical behavior across temperature and time.

Engineers specifying this part can rely on the UHW series’ focus on miniature size and high ripple capability while taking advantage of low leakage and controlled loss characteristics for predictable circuit performance.
