UHV1V122MHD

The UHV1V122MHD from Nichicon is a radial-lead aluminum electrolytic capacitor in the UHV series, offering 1200 µF capacitance at 35 V with a polarized radial can package (φ12.5 × 25 mm). It combines high ripple-current handling and low impedance characteristics to support general-purpose power smoothing and decoupling in compact assemblies.

Designed for robust operation from −40°C to 105°C with a 6000-hour endurance at 105°C, this part delivers long-term stability and RoHS-compliant material construction for industrial and electronic power applications.

Key Features

• Capacitance and Voltage — 1200 µF nominal capacitance with ±20% tolerance at a rated voltage of 35 V for bulk energy storage and DC filtering.
• Low Impedance — Specified impedance of 41 mΩ, supporting effective high-frequency performance and improved ripple attenuation.
• High Ripple Current Capability — Rated ripple current of 1.914 A at 120 Hz and 3.19 A at 100 kHz, enabling sustained AC stress handling in switching environments.
• Thermal and Lifetime Performance — Operates from −40°C to 105°C with an endurance rating of 6000 hours at 105°C for prolonged reliability under elevated temperature conditions.
• Compact Radial Package — φ12.5 × 25 mm can with 5 mm lead spacing (±0.5 mm), suitable for through‑hole board layouts requiring a small footprint.
• Leakage and Polarization — Polarized device with specified leakage current of 420 µA; suited for DC filter and smoothing applications where polarity is maintained.
• Packaging and Production Status — Available in bulk (no terminal forming) or bag packing; part is in mass production and RoHS-compliant.

Typical Applications

• Switching Power Supplies — Bulk filtering and output smoothing where high ripple currents and low impedance at high frequency improve regulation performance.
• Power Conversion Modules — DC-link and decoupling duties in compact power stages that require sustained ripple handling and long thermal endurance.
• Industrial Control Electronics — Energy storage and transient suppression in industrial boards operating across −40°C to 105°C and demanding long life.

Unique Advantages

• High Ripple Endurance: Ripple ratings up to 3.19 A at 100 kHz let designers handle high-frequency switching stress without oversized cans.
• Low-Impedance Performance: 41 mΩ impedance supports improved high-frequency filtering and tighter voltage regulation in compact assemblies.
• Long-Term Thermal Reliability: 6000 hours at 105°C endurance provides predictable ageing behavior for designs exposed to sustained elevated temperatures.
• Compact Footprint: φ12.5 × 25 mm radial can with 5 mm lead spacing enables space-efficient through-hole layouts while retaining substantial capacitance.
• RoHS Compliant: Material compliance supports environmental requirements for modern electronic products.
