UVY1H3R3MDD

The UVY1H3R3MDD is a radial-lead aluminum electrolytic capacitor designed for general-purpose power-decoupling and filtering tasks. It delivers 3.3 µF capacitance at a 50 V rating in a compact φ5 × 11 mm can, making it suitable for space-constrained boards and small power modules.

Engineered for wide temperature operation (−55°C to 105°C) and specified endurance (1000 hours at 105°C), this component provides defined electrical characteristics including low-frequency and high-frequency ripple current ratings and low leakage current, with RoHS compliance.

Key Features

• Capacitance & Voltage: 3.3 µF nominal capacitance with a rated voltage of 50 V and tolerance of −20% to +20%.
• Dielectric Loss (tan δ): tanδ = 0.12 measured at 20°C, 120 Hz, providing predictable dissipation characteristics for AC and ripple environments.
• Ripple Current Ratings: Low-frequency ripple current 25 mA at 120 Hz and high-frequency ripple current 50 mA at 10 kHz, enabling defined AC load handling across common power frequencies.
• Low Leakage: Leakage current specified at 4.95 µA, supporting low-standby and low-bias-current circuits.
• Wide Temperature Range: Operating from −55°C to 105°C to support designs exposed to broad ambient conditions.
• Endurance: Lifetime/endurance specified as 1000 hours at 105°C for reliable performance over the defined operating profile.
• Compact Radial Package: φ5 × 11 mm can (L: 1.1 cm × D: 0.5 cm) with 2.0 mm lead spacing (±0.5 mm tolerance) for through-hole assembly and straightforward board placement.
• Polarized Construction: Polarized aluminum electrolytic format for DC smoothing and power supply decoupling applications.
• Packaging Options: Available in bulk (no terminal forming) and bag packing to suit manual or automated handling preferences.
• RoHS Compliant: Meets RoHS requirements for use in lead-restricted designs.

Typical Applications

• Power-supply decoupling: Local DC smoothing and ripple reduction in small power modules where 50 V rating and compact size are required.
• Control and instrumentation: Energy buffering and stability improvement in sensor interfaces and control circuitry operating across a wide temperature range.
• Standby and low-current circuits: Filtering and hold-up where low leakage current (4.95 µA) helps minimize standby power draw.

Unique Advantages

• Space-efficient radial can: φ5 × 11 mm package provides capacitance in a small footprint for compact PCB layouts.
• Defined ripple-handling across frequencies: Specified ripple currents at 120 Hz and 10 kHz allow designers to quantify AC stress for both line-frequency and higher-frequency switching environments.
• Low leakage for power-sensitive designs: 4.95 µA leakage current supports low-bias applications and longer battery life in standby modes.
• Wide operating temperature: −55°C to 105°C rating enables deployment in systems exposed to extreme ambient conditions within the specified range.
• Predictable end-of-life characteristics: 1000-hour endurance at 105°C gives a measurable reliability baseline for thermal stress planning.
• RoHS compliance: Suitable for designs requiring lead-restriction conformity.
